Headlight-Battery Phone Charging Adapter

As I’m heading out for a three day snow-shoe hike with friends tomorrow, I quickly hacked an adapter which enables me to charge my phone from my headlight LiPo batteries. This way I don’t need an additional backup for my phone.

In one of my junk-boxes I found a 5.5mm plug which matches the batteries. For the phone end I simply cut some left-over micro-USB cable. I wired it all up with a 5V 500mA Step-Down Voltage Regulator from Pololu and insulated my beautiful soldering job with heaps of hot glue and a silicone cover from an LED strip 😀
