Solar USB Charger: 11 Steps

Imagine yourself fishing on the pier enjoying your day, fish are biting like crazy, all of a sudden your phone rings, then before you can see who’s calling, your phone dies! Now, you are dying to know if that missed call was that important one. Should you wrap up an awesome fishing day to go recharge your battery?

For you who have dead battery phobia like I do, here is a DIY gadget that you can make yourself out of simple stuff that you could find laying around (well not all of them but it’s pretty cheap to buy). You will need:

1. 4x solar garden lanterns (I used the one you can see on the picture)-

2. 4x rechargeable AA batteries-

3. a double USB port-

4. 4x 150k ohm resistor-

5. 4x 560k ohm resistor-

6. 1x diode (no LED)-

7. a little bit of plywood-

8. a little bit of some kind of strong wood-

9. some isolation tape-

10. a little bit of wire-

11. solder-

12. some green spray paint-

13. some white paint-

14. some hot glue
