Anybody tried to use standart HTC 5V wall charger for Flyer?
I have HD2 and its charger can safely give 1A. This type of chargers have USB data pins shortened. So all HTC devices conneced by standart USB cable identifies it as AC charger. I have tried to connect Flyer for a half a minute. Charger was identified as AC and as I remeber (not shure...and afraid to test once more) Flyer was sucking more than 1A (Battery monitor pro).
Flyer AC charger is 9V 1.62A, standart charger 5V 1A so question is do Flyer detects difference between Flyer charger and Standart 5V charger? Is it safe and possible to use standart 5V charger?
yes you can use standard USB, it will just charge slower

Have you tried or you just think so?
If flyer tries to get more than 1A, yes it will charge slower, but it will also burn charger.
I charge with reg usb all the time

I do it routinely. The device cannot draw more than the usb port will supply. PC ports supply only 0.5 amp. So they will only work if you turn the power off the Flyer. Wall chargers vary, some supply 1 amp. The original is 9v 1.6 amp were usb chargers typically are 5v so they will charge slower, much slower in some cases.

Sorry for last several anoying questions. Just want to be shure.
1. Do you use HTC charger or other vendor? In most cases only HTC 5V chargers are identified as 1A AC chargers. If not - device will not request more tha 500ma in order not to burn USB port (device thinks that it is port in that case)
2. Did you see that Flyer identified charger as AC source?
3. Did you charge when battery was less than 10%, what was charge current value on Flyer
Ok, now its getting annoying, did you actually read the information I put in the post you quoted? You just ask me the same questions I already answered.
The chargers all run on AC and produce DC . Flyer original output is 9 Vdc 1.6 amp .

Sorry but I think you did not gave the anwer. My english is not so good so maybe the question was not clear. I will try to explain once more, it is up to you to answer or just end this conversation/thread if you think i asked same stupid question once more.
1. Usually non HTC 5V chargers on HTC devices are identified as USB port and thats why devices draws no more than 500mA. It made so no to burn USB port.
2. All 5V HTC chargers on HTC devices are identified as AC 1A, so devices try to get as much as thay can (usually phones request less than 1A).
3. HTC Flyer with empty battery can request no more than 9*1.6A=14.4W. Flyer charger can handle that. Standart can handle only 5*1A=5W.
The question was: do 5V 1A HTC charger will not burn because Flyer identifies charger as AC and can request more than 1A. USB ports usually have protection from current. I do not know if 5V HTC chargers has protection or do Flyer identifies difference between 9v and 5v chargers and sets max current it can get from charger?
extra pins not present on a usb cable for mains charging. if using usb cables the the flyer is a usb device and has the same power restrictions as any other device...simple as that.

You are not right.
HTC 5V HTC mains charger comes with standart USB cable with no extra pins. Thats true. But mains charger has Data+and Data- shortened inside what makes HTC phones think that it is mains... with any USB cable. So power restrictions will not be as for USB....but as for AC. I have tested that in practice. I made belkin car charger and iphone charger able to be treated as mains chargers just by connecting pins (iphone charger data pins should be disconnected from schema before connecting. I have secret how to connect pins without opening unopenable iPhone charger....).
So the question is Flyer is able to identify mains 5V1A and 9V1.6A difference and do it apply different restrictions. Now for both shows it as AC source and I think sucks as much amps as it can up to 1.6A. So teoretically it should burn 5V charger if it will suck more than 1A.
What are you trying to do exactly?

by the way, it is standard, not standart.
I use the Flyer with a variety of USB wall chargers, car chargers and PC ports and have never experienced fire or explosion, only charging and slow charging. Are you trying to figure out how to use a different charger and still get a rapid charge rate?
Ok, I think I understand what the question really is but it is poorly phrased.
On my previous statement I agree with your answer in terms of how it is possible to read what I had said, in fact probably the logical way to read it on re-reading what I wrote, what I meant was electrically present, not that there were extra physical pins, whether electrically present is hi or lo doesn't matter.
If the question is can you rapid charge at 5V from a sufficiently powerful 5v then the answer is no, even if you pull D+ and D- to ground. Also it is highly likely that in the AC charger a resistor rather than direct connection is used to pull them to ground and these resistors could be electrically significant in the overall charging circuit.
The most probable reason for this is that there are two parallel charging circuits in the flyer ( almost certain of this ), and hence why 9v is used. The charge voltage for a 3.7v battery is 4.2 volts and somewhere around 500-750mA, the second charging circuit will have an isolation circuit to ensure that it is only engaged for charging purposes and does not directly feed the tablet that would be the purpose of the modified connections of d+ and d-, activate the secondary charging circuit.
Assuming you feed the device 5v from usb that would mean that the second circuit would receive a 0.8v supply, probably (hopefully) not enough to activate it so you just burn up the extra as heat in the circuit. In theory you would see a higher current draw by asking the flyer to run as if it was connected to an 9v supply when you connect a 5v supply. Best and most likely case scenario you're just being inefficient, medium case you burn out a component or protection (eg thermal fuse), worst case scenario you reverse the battery and it gets damaged or explodes.

This is what i meant! I was curious which one of scenarious will happen in practice.
From DigitalMD post above I can make a conclusion that in reality we will have 1st scenario (just inefficient).
Thank you guys.
I recommend you look at the following USB battery charging spec. A properly designed charging circuit will have current limiting and can recognize the power capabilities of the port vs. device vs. cable. This is why some charging circuits use a special cable vs. a standard USB data cable.

Nice link, it's got some pretty decent information in it.
Honestly to answer your previous question I can't tell, I'm guessing nothing except some heat, but that doesn't mean that you couldn't thermally damage something ( eg the screen ).

I think that there is no chance to damage Flyer thermally But theoretically, if Flyer wll requests more than 1A charger can overheet and possibly damage the Flyer. But if Flyer can detect that charger as 5V1A and if it can request less than 1A, then it is safe. Also if charger can detect current higher than 1A and can limit it - that also should be safe to use it.
I will read pdf maybe there will be some good info.
I use a self powered usb hub as a daily charger for both my Flyer and Kindle. Works fine. With no "burning out". At work, I use a generic 5v 1a charger, no problems either except for charge speed...
The charge state shows USB instead of AC, so it appears there is some sort of voltage/amp sensing going on?

Your flyer identifies charger and hub as USB and limits current to 500ma. The initial discussion was about the case when 5V1A charger is identified as AC. This case happens when standart htc phone charger is used (eg HD2 charger). That charger has data pins shortened inside that makes HTC phones (conected by standart USB cable) think that charger is AC. Surprisingly Flyer identifies it also as AC. In that case flyer do not limit current and possibly tries to draw 15W from 5V charger which can deliver only 5W ! I think that good chargers should have protection from oveload....
So soldering data pins together in you generic charger would make it more efficient. I modified my all generic chargers even genuine iphone charger and now all HTC and possibly other phones identify them as AC !! But I still not shure is that safe for flyer.
Little bit offtopic:
Yesterday i dissasembled Griffin car charger thas has 2x1A USB ports. In fact there is a chip inside that can deliver up to 3A. The chip is XL1583E1. This chip can be set to deliver other voltage than 5V by changing resistor.
It would be nice to get somewhere flyer pinouts and see if it uses the same pins for 5V and 9V charging. If the same - it means that this car charger can charge flyer as fast as flyer mains charger just coupling data pins (now it has identifications circuitry for iphone -resistors between vcc,data,data,vdd). If not - it means that charger shoud be modified to deliver 9V and special cable with extra pins will be needed also.
you sure are going through a lot of contortions just to do same things that the HTC charger that comes in the box already does. Why not use the adapter made for the device?
I've got around 4 different micro-USB AC Adapters that I have lying around. One is the OEM Lenovo, One is OEM Samsung (i777 charger + Samsung Micro-USB cable), one is a multi-USB port AC adapter with a micro-usb cable, and the last is an iPad 2 wall charger with a micro-USB cable.
ALL of the chargers except the OEM Lenovo ones don't charge my tablet. When It's plugged in, for a couple of seconds it says Charging (AC), and then it just switches to discharging. I've tried all the aforementioned chargers and cables in different combinations, and the ONLY ones to work correctly is the Lenovo combo.
Is there a specific reason to this? Also tried all 4 cables connected to my PC.. They all don't charge efficiently at all.
look at the Voltage and Amperage of the adapter !
Lenovo use 2A if I remember well, the other use only 1A
quyTam is correct... most USB chargers are between 500mA and 850mA. The dual battery design of the tablets requires a min of 2A to charge correctly. This is why most computer USB ports will not charge the device.
However... the changer isn't the only thing restricting the power. The cable you are using can also effect power. Not all cables are created equal.
I stopped by Staples just after getting my tablet and picked up a 4 port 2.1A USB wall charger. It will charge my phone, Bluetooth, and tablet. There are also really nice 2A "extra battery" devices out there that allow you to a charged battery with you that will power and recharge your device.
I also recommend the dock for the tablet... it has a 65w power supply and charges the tablet in a 1/3 the time then the usb chargers.
where to get a charger
i tried 2Amp chargers....didn't help/
my brother says:
"the pins are slightly different/off/longer/shorter/what DID lenovo do here?"
as a safety i bought:
http://www.ebay.com/sch/?_kw=886605022780&_clu=2&_fcid=100&_fvi=1&_localstpos=&_stpos=&gbr=1
just in case...
it costs an arm and a leg for a microUSB charger, but not charging the device for a couple of days would cost me more :S
just another things that makes the TPT slightly less then perfect
o,O
Charger
I use a Dell Axim x51 charger and an LG cable from an old phone. Seems to work very well and eBay prices for the charger are less than $4.

In my experience a 1A charger will also work. Nothing less than 1A will do anything.
I keep my Lenovo charger in my home office and use a 1A phone charger next to my bed for overnight charging.
I too have a 4 port mains to USB charger: 2A but I thought it was distributed to the 4 ports. If all were being used then each port would only be .5A.
Will have to try it out. If it works it would lighten the travel load of chargers.

The tablet needs to see 5.3 V, when using >500mA.
Already thinner USB-Cables increase the voltage drop
so the thinkpad wont charge, even with the original charger.
It may have less to do with your charger than with the cables. I bought extra long (6 and 10 ft) USB cables for charging phone and my TPT. The 28AWG of any length won't charge the TPT. The 24AWG 6 ft and 10ft cable *will* on a 2A charger. I haven't tried other combinations. I believe it will charge on a 1A charger as well, but would likely require the larger 24AWG cable.

Design Flaw in Thinkpad Tablet prevents Landscape Mode Charging for Developers
I actually sent my 1838-22U in for service, thinking that there was a hardware problem preventing charging while connected via USB. At first I had noticed that while connected directly to a PC via USB for development purposes (no docking station), the unit indicated that it was charging. However, it seemed to be discharging faster than it was charging and slowly worked its way down to unusable. Lenovo Tech Support indicated that they had heard of this happening, and that I should send it in to have its system board replaced. I sent it in only to find that all they had done was replace the battery and reload the firmware. I did notice, however, that when I connected the USB cable, it appeared to go into charging mode for a couple of seconds then switch into discharge mode. I asked Tech Support about this and they said they this was actually the way it should have been behaving all along, and that this was by design.
The User Manual (see attachment) states only that it might not charge, and that it will only discharge if the tablet "exceeds USB 2.0 power limits" (i.e. 500ma).
Well, the Thinkpad Tablet seems to be pretty good at doing that.
Here's where I present to the development community a conundrum. How can one develop in landscape mode while charging (even slowly)? In portrait mode, one can use the accessory docking station, which uses its own charger and charges through the proprietary connector next to the micro USB port, while separately allowing the USB to be used for data. In landscape mode, there is no such option. I will accept that the unit may draw too much current to charge well via a 500ma USB data connection, but then Lenovo should provide a optional charger that connects directly to the same proprietary connector used by the docking station. This is done elsewhere. For instance, Motorola realizes that the Xoom draws too much current to charge via a USB data connection, so they don't even bother with it - they provide a dedicated charger connection and charger.
==UPDATE== 25-May-2012
SOLUTION FOUND
The solution to using a data connection and charging the Thinkpad Tablet at the same time, without relying on the portrait-mode-only Dock Station, is to connect through a powered USB hub which supports the USB Battery Charging Specification (with a Charging Downstream Port). The specification provides at least 1.5A, which quite handily satisfies the Thinkpad. I found such a hub, the GWCTech HU2V40, on Amazon for $15.99.
If you get this model, note that only one of the 4 ports can be used for high-current charging. It includes a tiny "Smart Charger Adapter" but which appears to block the data connection (at least when when used with the Thinkpad). In other words, ignore the little black passthrough adapter included with it, and plug directly in as you normally would. The instructions don't explain the purpose of the passthrough adapter.
Hi everyone!
I just wanted to ask this: I just bought a 90W charger for my laptop. It is a "Targus Compact Charger for laptop and usb tablet"
It charges my laptop and also has that usb port which charges through a cable, compatible devices. Only that on that usb port, it says that it charges 2.1A, which is a lot. My phone charger does only 550mAh.
So the question, shouldn't I charge my phone through the adapter?
Thanks in advance!
Has anyone successfully used a 12v usb charger other than the BN ripoff? I have a gmax 2.1a and aluratek 2a and neither one will charge the bn tablet. I get the "not charging" message on the tablet.. so I supposed its getting some juice, but not enough to sustain it. I soldered d+/d- together on both adapters and now both will show ac charging in the nexus - so I know each is getting close to 1amp. Ironically, the tablet will show ac charging if I use the nexus power ac power cube which is rated at 5v / 1amp output. So you would think the 12v usb adapters which are rated the same would work as well.
thoughts?

There's also the part of the equation where the USB adapter must supply a lot more than the 500mA of current that most adapters and computer USB ports are limited to. Mine will say "charging" as long as the adapter puts out around 1A (1000mA) or more and I use the NT's supplied cable. <-- But it still won't charge as quickly as it does when I use a 2A charger such as the one it came with. The factory charger is around 2A and expecting the NT to charge with anything less may not result how you'd like. Just because your phone likes a charger doesn't mean your NT will.
There is more to it than just shorting the D+ and D- pins. If the charger was designed for iPad, then you will also need to remove 4 resistors. Check out the two links in my post relating this issue at http://forum.xda-developers.com/showthread.php?t=1614091
I modded a car charger by just shorting the two pins. My HTC EVO 4G phone showed AC charging but my NT showed USB charging. I opened it up again and removed the resistors network and NT showed AC charging right away. Good luck.
bigdogz - good advice - made an attempt at it but my eyesight and hand steadiness aint what it used to be However, I did find one that works - Scosche reviveII - GUSBC3. Its a 2.1a port for the galaxy tab and a 1amp port for apple. It charges both the galaxy tab 10.1 and the nook tablet on the 2.1a port. It also will charge in ac mode a galaxy nexus from the tab port. The 1a port does not have the d pins shorted, but will charge an iphone.
can someone point me to some car chargers, that have dual input(able to charge 2 items at the same time),but i need that full 1amp power so i can keep my note charging WHILE using it

I haven't come across a dual USB charger that will put 1A into an Android phone out of the box. If you don't mind buying a USB cable that has the data pins shorted (so the phone recognizes it as a dedicated charger), then the Griffin Powerjolt dual USB car charger (1A each port) is nice.

The Note will only charge at about 1/2A until you use cables with the data pins shorted together (I shorted the data pins inside the charger).
It looks nice (almost like in came with the car since it sits about flush with your dash). I can confirm it can put 1A into the Note (using Current Widget).

So it's not the car adapter that's not putting out 1A, it's the USB cable? If I were to use any car adapter + charging USB cable, my GNote would charge at full rate?
Also: how do I know if my USB cable is strictly charging or charging + data?

The charger has to be capable of putting out 1A or more for our Notes. If the voltage regulator inside the charger can't put out >=1A, then having the data pins shorted won't do any good. But if it can put out 1A+ and you don't have the data pins shorted, then the Note won't draw the full 1A. A lot of car chargers capable of 1A+ don't have the data pins shorted. I have read some people have luck with a OEM Motorola (1A out of the box) and I believe there is at least one Rocketfish charger (sold at Bestbuy) that gives 1A out of the box (although it only has one USB output). The problem is most chargers are meant to be compatible with iDevices and don't try to comply with the USB spec.
Most likely the data pins aren't shorted on any cable you have. Even if you have a charge only cable, it is probably just missing the data wires (not shorted). A few guys at work were buying cables off Ebay that were purposely made to have the data pins shorted. There are a few threads here on XDA (in the Note sections) that discuss various chargers and the need to short the data pins together.

i used the voltage widget(as he mentioned) to check and see if it puts out 1am
just download/install the widget,plug into phone, and see what the widget says
if its 5,000 or less, then its running at only .5 amp
i see at least 9,000 (though it should be 10,000 or so) when 1amp is running
If you don't want to cut into a cable and solder, you can use:

With shipping, its kind of expensive. I ordered a few (shipping costs the same as for 1) and put one in the car because, without it, the cable I was using only charged at 500 ma.

thanks but i already tried that
it worked great for about a month (full 1amp) but now its conked out on me
so i was trying to go the shorted charger route this time, instead of an adapter
is there an instruction book somewhere that shows how to short cable?

I have a ton of Qualcomm quick chargers and I'm not feeling this Dash charge with its special cable restriction. I saw this adapter and from the reddit posts, it seems to work well. It even works with normal USB Type C cable. Does anyone have experience with it and the 6T?
https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=SFC+AFC+VOOC+SCP&_sacat=0
I have some coming in the mail as we speak - I will let you know once I get them tested. There are supposedly some signaling differences between different OP versions, which may require a new adapter.
My take is that none of the WEB- adapters (on eBay) would work with the 6T, since that manufacturer is already selling a specialized adapter for OP beyond or equals to 5T. The WEB- adapters, however, offer a wider range of fast charge protocols as opposed to the YZXStudio adapter, which supports only VOOC-DASH. The YZXStudio adapter also has a current cap, which you can slightly adjust by soldering pins on the adapter itself. You are unlikely to get the full benefit of DASH from the YZXStudio adapter because of this cap, although your Quick Charge chargers most likely will be the limiting factor. Also note that the WEB- adapters require an input of at least 10 or so volts, so their A2A adapters will automatically request QC2/3 @ 12V. If your adapter does not support 12V, then it would not work properly. Your adapter should at least output 12V @ 1.5A for it to be any good after conversion losses.
This cable works although it seems to have gone out of stock.

I think the OP is trying to avoid using OP specific cables but rather use a QC2/3-DASH adapter and a normal USB-C cable for charging the phone. That said, aftermarket cables are not that expensive on AliExpress, eBay, or even Amazon. Although if you insist, I would encourage that you get heavier gauge USB cables for this...

Thank you for the information. Please let me know what you can find. I do have QC adapters that support 12V. If there're adapters that works, I rather buy those instead of investing in new bricks, cables, car chargers, battery packs,... My other devices either support QC or PD. Investing in Dash charger doesn't make any sense at all.

I hear you - I did buy a multifunction car charger that supports both QC3.0 and DASH - I will report whether that works when it comes (hopefully later in the week if not the following week). I have also gotten the specialized versions from WEB- in China so once I get those I will let you know.
So I got one of the adapters today - this is an older version that does DC to Type C, so I did not expect it to work (even though it specifically listed VOOC and DASH support - maybe it worked for an older OP version).
This one was from eBay, and supposedly the seller sent me the wrong item (WEB- makes a 12V and a 20V PD version - and instead of the 20V version they sent me the 12V version instead - which can only decrease voltage due to the builtin buck converter inside).
So the question is - does it work with DASH charging? --- No, it did not. However, it is still an interesting adapter because it has broad fast charge technology support. They market this little adapter to convert your "dumb" laptop charger into a "multifunctional charger."
Interesting facts:
1. This adapter requires 12V for it to function. It does start turning on at around 11V or so, and anything below that will cause the output to shut off and the operation light to go red. The USB to USB version automatically requests QC @ 12V, but obviously, this cannot be done on a DC jack (on this particular version).
2. As soon as the voltage going in exceeds 11.5V, the output turns on with a steady blue status indication.
3. The USB-C version of this adapter supports USB-C Power Delivery (PD2.0) with three selectable voltages 5.00V @ 3.03A, 9.00V @ 2.39A, 12.00V @ 2.31A (there is a 20V version that supposedly does 15 and 20V as well for laptops, but the seller sent me the wrong version).
4. The input side is a 5.5 x 2.5 DC jack, which is somewhat odd as an input because most input jacks use the smaller 5.5 x 2.1 jack (you can use an adapter on it, however).
5. You can see from the tester that this adapter supports pretty much everything, except VOOC/DASH and 20V QC and AFC 12V.
6. QC 2.0 9V engages just fine to charge my older Nexus 6 via a USB-C to USB-A adapter (since the D+/D- lines are intact).
I do have more adapters coming in soon so I will let you know how they go once they come in (including the WEB- VOOC/DASH specialized USB-USB adapter). This particular version may be a fun adapter to play with, although it won't really help with DASH charging on the OnePlus.

Here's an update on the car adapter I have received. Note that the other adapters are still on the slow boat so I will get to them when they arrive. This isn't necessarily what you are after, but nonetheless, it's another interesting toy. If you are interested, it can be found on AliExpress under item number 32916499372.
This is a car charger that accepts 12-24V input, and also supposedly supports multiple fast charging technologies (DASH, VOOC, QC, etc). It comes with an "original" (questionable - but capable of 3.5A charge) DASH cable which is not bad at all for about $13.
Interesting facts:
1) The car charger comes with dual USB ports. One "quick charge" port and one "standard" port. The quick charge port lights up red on one side and the blue indicates the normal charge port. Some may like that it lights up, but my thought is that it's a waste of energy.
2) The Quick Charge port supports all available quick charge methods (the VOOC-DASH section don't light up probably because it doesn't use the same protocol for unblocking DASH charging that the original charger requires).
3) The charger does not require an ID chip on the USB-C cable (unlike the stock charger), which means you can use any USB-A to USB-C cable on the market to activate DASH charging (as long as the D+/D- pins are not shorted out). This car charger doesn't even have the odd PIN in the back of the USB connector for the ID communication.
4) The car charger is not as fast as the stock wall charger, which charges around 3.5A. Here are the test comparisons (allow some current variances due to battery percentage ~70-72% - note all of them had the lightning bolt on the charging indicator which indicated that DASH was indeed activated with none of these cables having D+/D- shorted):
a) Normal, 1 ft USB-A to C Cable: 2.46A
b) Bundled DASH cable, w/ car charger: 2.73A
c) Bundled DASH cable, w/ stock wall charger: 3.5A
d) Normal, 3 ft (Rankie) USB C Cable: 2.56A
e) Normal, 3 ft MicroUSB w/ USB-C Adapter (ANKER): 1.95A
f) Normal, 3 ft multi (MicroUSB + Type C) free conference charging cable: 1.32A (this one did not "pass" the fast charging test because the current is below 1.5A but nonetheless it triggered DASH charging).
Not a big difference if you use quality cables, although don't expect it to charge as fast as the wall charger - nonetheless, it is still doing pretty well with less heat generated due to lesser current.
5) As mentioned previously, the charger supports multiple charging technologies besides DASH, where it activated QC 2.0 9V on my Nexus 6 just fine.
6) Since this adapter allows 12-24V DC input, you can use a DC to lighter adapter to power this device (as you can see in my screenshots I used a laptop battery pack and a 12V router wall brick and it was able to turn on and charge my devices just fine.) This may also be a good way to have a longer reach charging solution since DASH is very cable sensitive and it is best to keep the cable length short to minimize the reduction in charging currents.
Here's a test of the 100 cm noodle cable on AliExpress (item 32806193071):
Using the stock wall charger, charging the phone @ ~50%:
The genuine OnePlus cable was able to charge at 3.657A @ 4.69V (17.15W).
The noodle cable on AliExpress was able to charge at 3.617A @ 4.81V (17.4W).
Based on the results, it seemed like the quality was as good as the genuine cable, at least the copper that is carrying the power to the phone.
Here are the test results of the final adapter I received from WEB- (the specialized VOOC-DASH version - Taobao Item #560336325713):
Stuff to note:
1) This adapter is very similar to the car adapter, in which it supports pretty much all quick charge technologies and it does not require the OnePlus ID chip to activate DASH charging. However, this adapter is QC activated and has a USB-A input interface. Like the car charger, this charger is also not as fast as the stock wall brick, although it is still relatively quick.)
2) The USB pinout schematic also looks the same as the car charger (USB 2.0 with no dangling USB 3.0 pin in the back for ID chip identification).
3) Like the other 12V based WEB- adapters, this one uses the IP6518C chipset, which supports a wide voltage input (10.5V - 32V - from the chipset datasheet).
4) The board looks fairly similar to the USB-C board, except this one has a USB-A input (which is interesting because the board has the DC 12V-24V marking on it still).
5) The board also has the POW and OK lights similar to the USB-C version.
6) Since the board accepts broad input voltages, it is not required to use QC for the input voltage. A USB-A to 5.5 x 2.1 adapter could be used to also provide the DC input, as long as the voltage is above 10.5V.
7) Although the board indeed supports down stepping a 20V DC input, it seems like it is a bit less efficient in doing so than a 12V input.
8) Similar to the previous cable tests, the quality and the length of the cable really makes a difference. The shorter and the better quality cable that is used, the better the charging rate (remember that an official cable does not need to be used for third-party chargers).
9) As mentioned previously, this charger supports other fast charging technologies, like QC2.0 - which works fine in charging my Nexus 6 at 9V.
10) This charger / adapter essentially allows any 12V @ 1.5A output to be a multifunction fast charger w/ DASH support. In my example, I used a Xiaomi router wall brick (12 V @ 1.5A DC) and it charges my phone using DASH at almost 3A output using a short 1ft USB-C cable! (the phone registers the current slightly lower at around 2750mA).
Great info, @chowfun. I was able to purchase 2 OPPO wall chargers from Asia and a 3rd party VOOC car charger which work great.

I also got the same oneplus flat cable but 150cm length. It works good with no notable slow down.
From your findings, it looks like the WEB- adapter charge slower but that's still plenty fast and much more convenience. :good: Does it generate a lot of heat when charging a low battery?
Nice keyboard, I like it. ?
That said, the Quick9 charger you bought probably does not require the ID chip as far as DASH is concerned. I didn't get that one because it had a lower current rating and that the top of the charger is wider than the other one I bought. I doubt the OPPO charger would work with a regular microUSB cable since I presume that it also requires the chip on the cable end... Did you also see what kind of maximum currents you are seeing on those chargers?
Heat wise, it does generate a bit of heat with the conversion. But given that the adapter is housed in an aluminum case it's to be expected. It feels just slightly warm to the touch, but not exactly hot to the touch. Instead of that conversion being done in the phone it's just being done outside the phone which is directing the heat away from the battery...

LOL. My wife doesn't like those RGB lights. lol
The input and output of the OPPO charger look exactly the same as the 1+ charger. It's pretty much identical except for the cosmetic (logo, prints, the USB A female is green). They're selling for $4.
