Docking connectors for extra DIY chargers??? - Eee Pad Transformer Accessories

Looks like others have found the docking connector used on the TF. Has anyone tried getting the connectors to make a simple DIY charge plug? I know just getting a universal 11V+ adapter is like 10$. With a little solder one could have a much cheaper charger for home.
Any info on which pins on the connector are for power? I am ordering some samples of the connectors just to see if its possible.

Please check this post "DIY TF101 charger and other charging methods" by Devcake for all the information you will need for your project.

Car charger for XDA..

Is there actually any components inside the cigarette lighter plug thats used to charge the XDA in-car?
As i'm getting one of the digitraveler gps receivers, and want to modify the cable to allow me to charge the xda whilst using the gps. The only problem is I don't have an in-car charger for my xda, i do have to spare cigarette lighter plugs though.
Would it be possible to just use one of the plugs and send the + feed to pins 20,21,22 and the - feed to 16,17 & 18 ? as in Yorch's guide (http://www.yorch.net) Or does this thing need resistors and things inside it ??
:?
Many Thanks
Swifty, I modified a usb sync/charger with the lighter socket adaptor, just add the wires from the digitraveler to the usb cable, you then end up with sync/charger, car charger and digitraveler y lead/xda charger.
:? Hmmm I think I understand what you mean.. I don't really want to touch the usb cradle i have though, I just want to add the lighter plug onto the gps cable, solely for the purpose of charging when using the GPS in the car.
Cheers
Swifty, not the cradle, I got a usb sync/charger and a car lighter adaptor from ebay, I modified this instead of trying to add wires to the digitravelers connecter. The thread is under another posting about a cheap gps. Also the cables that come with it need to be modified to work with xda.
Yeh, I understand what your saying, but I'd rather not have to buy a car charger or whatever to then hack it about. Not when I have got several lighter plugs lying around, if I can use one of them... :wink:
Cheers
OK, if you use a standard plug end, you will blow it, if however you have an old phone charger lead that gives 5volts that should do the trick I think.
Aha! thats what i'm after, cheers mate
Anyone confirm its 5v I need before I cook my XDA :lol:
Cheers
The HTC XDA/Qtek must be feeded with 5 V. The current consumption can be as high as 1A when in use and charging internal battery.
I have made my own 5V regulator for car use, but this require some experience in electronics.
Here's what I have installed, with converter schematics.
More info here.

Spare Battery Charger anyone?

Has anyone found a craddle that could charge a spare battery for the Mini S? Have found so many spare batteries with extra power but no chargers. Its really weird why nobody has thought of bringing out one? I am sure there is a lot of demand. Wonder what the issue could be? Any ideas anyone?
I'm trying to make a charger for my Blue Angel batteries - I find the cradle too big when travelling. I'm thinking of super-glueing electronics board with some solder onto crocodile clips and attaching a USB plug to the end of the wires to be used with a USB charger. I haven't figured out which strips on the battery are positive and negative yet.

Transformer Prime Charging

I just want to make sure I am clear on the whole 5V, 5V+ charging. Is it true if you can some how provide 12V over USB (yes this is sort of a hack) you can get reasonably decent charging rates? I ask because I'm in the market for a large portable battery pack (in the 10Ah 3.7V range). Some of them provide 12V output to a DC barrel plug.
Someone in the original Transformer prime suggest buying a DC plug to female USB plug adapter off eBay. They sell multiple sizes of these, so I figured that if I can find the right size adapter for the DC plug, the battery pack should be able to charge my Prime? The only problem is if I pull a brain fart and accidentally plug my phone in that
Somewhere in the forum is a thread about DIY chargers ....maybe under accessories.....gives the pins for USB3 connection, and maybe USB2....The ASUS connection is USB3....different power pins from usb2

Wireless charging and charging with cable Issue

As the Huawei mate 10 pro has no wireless charging i've been looking for qi recievers for USB-C. Plenty of them. But i still haven't found what i am looking for(nice title for a song). One time i want wireless charging the other time i want charging by cable. Of course i can pull out the plug of the receiver but after a while this will definitely be broken and is also not handy when carrying the phone in the pocket. What i am looking for is a qi receiver wich is connected to the USB C port but also have an entrance for an USB -C Cable. Anyone knows if this exists?
I was once looking for a iPhone solution that didn't involved a thick case, and I came with the answer that a simple pass-through is not possible, some protetiction and routing circuit is needed...
So maybe aim for a case? But I also couldn't find anything.
So....
hey there, this is exactly what I am too looking for a qi coil that can be neatly tucked between the phone and the eternal protective case and has a usb c port which is also female so it can take in the usb charging without having to take anything apart, I imagine it to be not to difficult of a think if one had the parts to just modify something in existence. eg usb c and usb -c (female). If anyone finds anything, drop a shout!

Sonim XP8 XP8800 Charger (2 charging pins on the back)

Is anyone using the charging pins on the back of our wonderful phone?
The genuine Sonim XP8 Single Bay Drop-In Charger seems quite steep on the price, but if there are no alternatives... :crying:
I would like to hear experience of real users, of the genuine charger and alternatives available please.
After spending a minute poking with the USB-C charger (the rubber door being in the way doesn't help) I realized that I will be wanting to use the back charging connectors.
can someone at least tell me the charging time with that charger please?

AT&T has the GPSLockbox single tray charger with slot for a spare battery to charge for around $30. I use that and I prefer it. Just drop it in and let it charge. The dock uses a micro-USB charger and not USB-C
