"DIY" USB Power Bank for 2x 18650 Li-Ion cells

Описание к видео "DIY" USB Power Bank for 2x 18650 Li-Ion cells

Test and teardown of a PowerBank designed for two 18650 Li-Ion batteries. The sellers on Ebay call it "DIY" for a simple reason - it comes with no cells and you have to put your own 18650 Li-Ion cells into it. For just $1.19 including shipping its not so bad, but there's no fuse and no protection against wrong polarity.

WARNING: Batteries and power banks can catch fire or explode! Risk of fire, injury and burns.
