I'm planning to buy a car charger for our mobiles including Z2 Plus. What are the specs that I should look for? Like wattage, Amp, voltage, etc.? Is there any specific brand or model that you can suggest?
I found a few over shopping sites and almost all of them have two ports, each having 2.4A thus making 4.8A total output (Sony, Flipkart Smartbuy, etc.). Are they good for our device?
Also, what if I connect my phones with 1A input? Will it harm those devices?

Dont use charger which is greater than 2.4A Voltage -5V. Lower amp is okay but over amperage can damage device

If anyone is looking for an alternative mains charger I can confirm that the charger for the current LG portable DVD range will fit just fine. They provide a full 2A current, so they are plenty strong enough for our tablets. These are readily available and reliable.
LG Models DP371B and DP581B and probably many more.
This is the way that I charge my g-Tablet in the UK, where US mains sockets are in short supply.
Do you mean this one?

That looks like the one that comes with the g-tablet. I saw a few people asking about alternatives and thought I'd share a working solution.
BTW the portable DVD players also come with regulating car power adapters which should work with the g-tablet.
If anyone knows where to buy alternative clip-in country-specific connectors for the standard power supply unit could they please let me know where to find them.

Thanks.. just bought three of them from a guy on eBay.
Hi,
I've read some threads here about charging the S3, but not all is clear to me. I would appreciate some explanation:
1) I've read that the stock chargers output 1A. However, on the charger I got with my S3 it's written "output: 5V 0.7A". So do you think I somehow got a wrong charger?
2) I want to buy a car charger for the S3. There are many generic car chargers in ebay, some of then output 2A current. What is the maximum current allowed for the S3? I couldn't find this number in my S3 manual or on the phone itself. Will a charger of 2A cause harm to my phone? or to the battery? or to both?
Thanks in advance!
bump... does anyone know?
My charger output states .05v=1.0a.
As for what aftermarket charger to buy, I would stay away from chargers with more output than the official for 'peace of mind that my charger's specifications are the same as the official charger that came with the phone' reasons.
Cheers
Generally wall chargers output 1000mA (1A) and USB ports 500mA (0.5A)
You do not want to purchase anything that goes above 1000mA

I attach a picture of the adapter I got with my S3.
It says 0.7A on it, while it appears that other have one with 1A.
Did they con me with this adapter?
And regarding the maximum current allowed: do you think an adapter of 1.2A might harm the S3?
Do not know where your S3 come from but this charger is not made For S3 but for S2!
I just checked the model number:
S3 charger: ETAOU81EBE
S2 charger: ETAOU10EBE (like yours)
And there is no cable on the S3 charger, it use the USB cable
Thank you for this!
I don't get it. The charger was inside the S3 box and looked original. Damn!
I think the store I bought from import their S3 from Germany, since it came with Vodafone German stock ROM. Is it possible that this is the charger they sell on German vodafon? Or perhaps the store switched it for some reason?
Mine also come from my carrier: french vodafone
Was your S3 box sealed?

Hi,
Background - I am an electronic engineer and have designed power supplies.
The Amp rating on a power supply is it's maximum capability to deliver power. The Voltage is the 'force' that it can push electrons through the device, this is the important one to have correct. So a 5V 300A Power supply will not charge your S3 any quicker than a 5V 1A power supply.
Get yourself a 1A car charger and you'll be fine. Depending on how the data pins on that charger are configured it'll be recognised as either a fast or slow charger but it will be fine in any case.
So, according to what you say, there should be not problem to use a 5V 2A charger on the S3?
The charger cannot accidentally push too much current to the device?
No. The phone limits the Amp the battery can get.
It simply won't go above 0.5 or 1Amp depending on what resistor is coded between the data pins (the 2 middle pins on the normal USB-plug)
(Note that this does not extend to all devices. E.g. cheap chinese toys and their batteries may not have any current limter, connecting them to "too powerful" chargers will result in damages or potential blow-up of the battery. The same applies to batteries without any electronic such as car batteries which can overheat and "cook")
I bought S3 in Germany 1.0A, there is a date on the charger:18.05.2012

Hi burmo,
An interesting concept. I have no clue in these things but what you say is not clear to me "all the way".
Charging my i93100 phone with 5.0V 3.1A will do no harm because it won't "push" more than 1A anyway?
And who is "responsible" for controlling this "push" the charger/battery/phone?
Does it work the same for Car chargers?
Thanks a lot,
Izik

so i have been wondering about this as well because i am currently building a custom charger for my s3 that charges the battery without having to plug into the charging port. i have redirected wires from the wireless charging port to metal tabs i have place on the back of my phone. it is a "drop in charger".
Anyway i have tested the charger that came with my phone. I also have the samsung stock charger that say the output is .7amp but after testing it with mutimeter, i have found that the output is actually 1.2 amps. As for max charging amps, I am not sure. I have tested several chargers. The new S4 charger puts out 2.34amps and i have not found any problem charging my s3 with it.

As far as I know the phone limits it so as you've found yes you will be fine
My original S3 charger is 5v 1.0amp
My original S3 charger is 5v 1.0amp. It was bought in Thailand with the phone.
I agree with burmo an advanced phone will have a current limiter as part of its circuit, however I prefer not to rely on it and not to exceed the manufacturer volt/amp recommendation.
The phone controls the current. In custom kernels (Boeffla and so on) you can change the target current. The phone has a protection built in, if the voltage is unstable (drops to much) it lowers the current untill the voltage is stable.
A HTC One charger I sometimes use (0,7A rated) only delivers 0,8A. A aftermarket charger I own (1,0A rated) is fine delivering 1,2A (modified target current, not stock). These charging currents can be read by various apps.
Get yourself a 1,0A rated charger and speed up your charging time.

Seconded the post above being an electronic engineer as wel.
Voltage should be exactly the same as you need, but this will always be the case for a USB charger.
Current should just be enough or more.
The charging current is dictated my your phone and not - and I repeat - NOT by your charger!
mine rates at 1A

I'm not very familiar with the iSound charger, does it provide a high enough Amp output?
When I got my Galaxy Tab 10.1v a couple of years ago, I bought some adapters that feature a resistor and a swap some pins around to ensure the device goes into charge mode and not data mode when plugged into a PC. The resistor enables a higher Amp output than you get from a normal USB port. I've checked ebay recently and found that there are even better adapters out now than what I bought in 2011, much more low profile.
Maybe one of these could help?

the output opportunity of your mobile power bank to produce the current with enough power Is significant . As example u can see my mobile Iconbit charger which produces two current opportunities: 2.1 A and 1A.
The first allows to charge my phone very fast, the second allows not to lose phone battery chargŠµ during walking with maps enabled.
So, may be your's power bank is not quite good to output good current. may be it was very good in past but battery have lost the capacity and opportunity to produce current.
Also I've throwd to the garbage a lot of adapters which had lost their opportunity to put goodie high current, a lot of famous brands also. During the year and half of Note 1 I've changed five batteries and three wall chargers. some changes I have bought to replace did not charge my phone.

Some good points here - particularly about charges and cables to degrade and lose their capability to provide a quality current - I've had to dispose of a few cables and chargers as well.
Still, the adapters that discussed earlier can help to a certain extent.
I've been looking at different Micro USB Charging Cables for my brand new Nexus 6 and I want to make sure that I'll still get the benefits of the Faster charging with a different cable. I found this, but I have no idea if any 3rd party cables can be used.
http://www.amazon.com/Mediabridge-U...11893&sr=8-2&keywords=nexus+6+micro+usb+cable
That cable will work fine. Pretty much any 3rd party cable will work.

Do NOT buy any cable from anywhere else. Unless it's cheaper, but it probably won't be. Their stuff has always been great and the selection is awesome.
http://www.monoprice.com/Search/Index?keyword=micro+usb
If you buy from monoprice and want a cable over 3 ft then you have to buy a "premium" cable and that costs more. I got this one on Amazon, it will give you the full charging speed at 6 ft or more:
http://www.amazon.com/gp/product/B00RB6881Y/
Keep in mind that to get the full speed with a cable longer than 3 ft you really need to get something like 24/28 AWG otherwise it can't carry the charge. I bought a bunch of 28/28 cables and none of them gave me the full speed. At 3 ft pretty much any cable will work.
10ft cable that is 28/28 from Mono Price is $1.27

It actually does work, IF you are using a QuickCharge charger. They increase the voltage, and lower the amperage. This in turn causes lower voltage drop over the cable, making the size less relevant. I have a pair of 10ft Monoprice 28/28s here, the charge speed is the same as the cable the phone comes with. Once it drops to 5V, the battery is already only allowing small currents to top it off anyway.
With a standard 5V charger, that article is dead on. And all things being equal, you generally do want the thicker ones, so do get them if they are available.

If it works for you then I'm envious, but I've got 3 Motorola chargers, 3 Nexus 6s and 8 6ft 28/28 cables that aren't doing it and for my money that's a pretty good sample. I only have all these because I manage the phone plan at work. When we bought the 24/28 6ft cables we had no issues.

Usually, it is not possible to draw full power simultaneous from all ports. There is an upper, overall limit on the power dissipation and if this is exceeded, all ports will become unstable.

24W are sufficient for two standard fast charging ports *or* one QuickCharge port at full power.
You will only be able to use all ports at the same time, if some devices draw significantly less than the maximum power at their respective port.
For a combined Fast/QuickCharge charger with an european plug i would probably choose something like these:
https://www.amazon.de/dp/B01DF165YA
https://www.amazon.de/dp/B01BEMEY4U
https://www.amazon.de/dp/B01KUV3Q0O
All provide QuickCharge 3.0, which may be desired by your next phone and should be upward-compatible to QC2.0.
The latter two feature a detachable power cord, which is more robust and more convenient than a wall charger. They also provide more total output power, which will actually allow you to use three ports at the same time.
All feature Smart Device detection feature on their fast charging ports.
