[DIY] High Current Micro USB Charging Cable From Cheap China Cable

[DIY] High Current Micro USB Charging Cable From Cheap China Cable:

WHY

I use Waze on my N5 every day during my commute to and from work. I find that the only micro USB cable I have that can still charge my N5 while running Waze is the OEM LG cable that came with it. I don't like the current state of affairs - where I'm reliant on just one cable with no backups.



WHAT

I've tried the regular 'Genuine' micro USB cables from China via Ebay that purport to handle Galaxy Note level charging, as well as 24/28 AWG cables that are supposed to handle increased currents. No joy.



NEED

- Pocket Knife

- Soldering iron + associated materials

- Electrical tape



HOW

I used a cheap, China, Ebay, micro USB cable that has a hard plastic casing around the connectors on either end of the cable; this makes it easier to pop the casing off, fiddle with the wires, and close everything up again.

(1) You begin by using a pocket knife to pop open the casings around both the USB A male and micro USB male connectors. Do this by firmly putting pressure via the blade edge on the seam between the casing halves. Once the blade has sunk about .5mm into the seam you then wiggle it to widen the gap. It may help to increase pressure on the seam by hinging the metal connector against the plastic (as if it was plugged in and someone decided to sit on the plastic). You'll see this when successful.







(2) Next, you take your soldering iron and move the green wire over to join the black wire, and the white wire over to join the red wire; on both connectors.

(3) Add a bit of a jumper between the D+ and D- connections on the micro USB connector (where the White and Green wires used to be) You'll see this when done.







(4) Finally, put the plastic connector covers back on and cleanly wrap them with some electrical tape.
