An emergency battery charger for your mobile phone comes in handy, but it's not the ultimate solution; once it's dead it's useless (what a waste). If you want to really get off the metaphorical grid, you can follow the steps in this video to construct a more robust circuit that will not only bail you out of an inconvenient situation but also recharge in between uses. The simple addition of a low voltage solar panel and rechargeable batteries makes this possible. Enjoy!
Parts:
4 x NiMH AAA Batteries
1 x 4 AAA battery holder
1 x Small PV (photovoltaic) solar cell
1 x Diode rated min 5V 500mA
1 x USB cable or cable of your choice
Tools Required:
Soldering Iron
Lead Solder (the kind with flux core is best)
Heavy Shears
Wire strippers
Electrical tape
Tips:Solder in a well ventilated area on a non flammable surface
ALWAYS WEAR EYE PROTECTIONCheck the circuit polarity before final soldering
