In this post, I’m going to cover building a portable USB device charging kit and how that fits well into your preps.

I’ll go over the how what and why of building a device charging kit.

I also cover the cost of building your charging kit, including an itemized list of everything I put in the best charging kit I own – which I just put together this week.

I won’t get all technical and geeky on you. Honestly, while I’ve been using these kits for the last five years, I have no interest in learning anything beyond what is necessary to make the best portable charging kits while keeping the costs down. I am not an electrician and won’t pretend to understand every aspect of these devices.
