Watch this shit on Youtube. Its much more entertaining

Today I took a 12v 17ah sealed lead acid battery and I combined it with a 12v USB adapter to make the world’s heaviest and most mediocre USB battery bank. Its “Portable”!

This Project consists primarily of a 12v 17ah sealed lead acid battery

And a 12v 4 port USB charger from Amazon.

I found a bigol sack to throw it all in

I clipped the male 12v plug off of the USB car battery charger thing

The handy dandy
circuit diagram for those playing at home

Solder that ish up.

Test that ish out

You charge it with a 12v battery charger. Easy peasy. you’re now the coolest kid on the block.
