If you've ever been out hiking, or been away from powered civilization for any length of time, you've surely run into the issue of how to power your devices. Portable power banks and solar chargers works great, but cost quite a lot of money. In this instructable I show you how to create your own portable charger, using materials which can be gathered for peanuts. Let's get started!

Materials

Car USB charger/cigarette lighter to USB converter
Battery holder for 8 AA batteries
8 AA batteries
Snap battery connector
On/off switch
Enclosure

Tools

Soldering iron
X-acto knife
Wire cutters


Now watch the video and make your own charger, and never fret again that you will have charge when you're out and about!

Stay classy Instructables!
