Welcome to my instructable!
Today i will show you how I made USB Power Bank.
It holds anywhere to 7000-16000mAh ,which depends on batteries you'r using. Capacity for C type batteries
This small device can be used to power any small gadget which use 5v USB input like those small rc quad copters and rc cars.
Module i'm using is USB step-up booster ,which boosts anywhere form 0.9V ~ 5V and can output stable 5V dc voltage. This will not charge your phone! For that application please use different kind of module.
Anyway back to project!

- I used switch as well
I used tools as :
- Soldering iron & soder
- Drill & drill bits
- Hot glue gun

Step 2: Preparing Parts and Project Box
I started by modifying battery holder and project box to fit each other.
Then i placed parts in project box and arranged them in order which they fit best.
Step 3: Soldering
Soldering is pretty straight foward.
Just solder positive to positive and negative to negative ,just remember to add switch between one of those wires so you can turn power bank on and off.
Step 4: All Done
After soldering all parts together you can put in batteries and close project box and your done!
This is how my project turned out , I'm pretty happy with result and it definitely dose what it's made for.
