As my microusb jack on my sgs4 is starting to wear out i was wandering if i could use the two terminals on the back for the Qi charging pad for charging with a USB powerblock or computer etc?
What i was thinkin is to take a USB lead and just keep the male USB A plug, bare the wires and then connect the red and black wires to the Qi charging terminals on my phone, thus providing my phone with another means of charging..
So i guess im wondering if its possible to put 5v DC on the Qi pad terminals without damaging anything..
Grateful for any help

Hello Friends,
i made myself a Carholder with Charger and Audio-Connection for my Wizard100. I took a Lm7805 to create +5V out from 12V of the Car Battery. I also took a normal Mini USB Plug, and connected the two wires who leads the Voltage to the unit with my 5V Regulator. When i turn on ignition in my car i could measure the 5Volts at the Cradle and when i plug in my Device the Charging LED goes Red and the Symbol in my Today Screen shows the charging. But when i pull out my Device after a while the batterypower goes down very fast and rapid. Why? Is there any conection that has to be done? How many pins are used to charge the Wizard by USB?
Charging current...
How much current is your rig capable of, the stock charger puts out 1 Amp. I know that the wizard is rather finicky 'bout its charging method. Hope this leads you in the right direction...as for pins, i would think that if it says its charging, then your pin outs are ok. It would most likely be about the amperage
The L7805 Regultaor IC fits up to 1.5A .Thats enough i suggest. Now i´ve ordered a real car charger and put the electronic in my carholder. What about grounding? Is ist allowed to put the Audio Ground together with the charging ground or must I divide both grounds?
Thanks so far for your replys...
hello,
i am trying to achieve inductive charging on my defy.
did- installed back cover coil- working
- soldered usb pins for connections.
now i need to shorten data pins to force defy to charge.
but Q - wont the inductive charging work when simple usb plug is connected?
with out special mod...
So its been a while since my s4 i9500 wall charger's cable been cut. Although the phone does get charged up. It isnt charging up quickly as it used to before the wire was cut. Sometimes the phone doesnt even charge even thought the battery icon shows that it is charging.
Now, I have been thinking of replacing the charger. But do i have to buy the charger or should i just replace the cables? I have a lot of micro usb cables . Can i use them with the adapter to charge up my phone?
You can use quite literally any micro-usb 2.0 cable and any usb charger to charge it; however, to achieve the maxium charging speed (1900mah) you will need a high quality shielded micro-usb cable (like the stock Samsung cable) and a 2A (or higher) usb charger (like the stock Samsung charger or an iPad charger).
I fried my charging port socket (don't ask -- coffee, I think). It smelled burned and the charger tip would get hot in the port. I bought a new charging port panel and properly installed it with the protective film removed from the bottom and carefully connected the ribbon cable. The phone will not accept input through the charging port micro USB, but it will charge on a wireless charger. Could I have fried the connector at the battery through which the plug-in power goes? Is there a separate circuit that inputs current from the wireless charger? Could that explain why changing the charging port circuit panel did not fix the problem? Should I buy a new battery and try that? Diagnostic help would be appreciated.
Hi folks,
I'm trying to fix my old Nubia with a broken USB port by bypassing the port.
Since it's soldered to the motherboard, it's almost impossible to solder right on the usb pins.
But I've noticed testpoints, and found the VCC one, on which I soldered a wire. another being soldered to the outside of the port for grounding.
I thought I would be able to charge it that way, but it's not showing any signs of life (with or without the battery)
So I have 2 questions:
-can I charge through the testpoints ?
-do I need to send a signal to the ID pin ? (I guess not, I opened up a charge only cable and it had only 2 wires)

I tried charging it with a lab psu and an Aukey Quickcharge 2 charger
Thanks for your help
