Portable Power Pack

Electronics, Outdoor Technology, Side Projects / By /

I recently built myself a portable battery pack out of 48 used 18650 cells that I got from https://batteryhookup.com.

Charging it up for the first time. Each pack is roughly 190Wh, for a total of about 380Wh.
Two 120v outlets and two 5v USB Ports capable of supplying a total of 155 Watts.
