Solutions for a raising battery range upgrade when PnR or VnR mode is impossible : DIY OUTDOOR POWER CHARGER

Recommended Posts


this is my first compact version for DIY outdoor power charger. 

I didn't invent anything, I just tried to make a case that was as easy to transport as it was efficient.


Yes it's a PLAYMOBIL case with a 10S3P (388Wh) li-ion battery (modified shape to fit in the box), a 600W booster DC/DC module (modified shape to be more slim), some wires and accessories (connector, power switch, electric tester) and it's done.

Very helpful for relaod my OW+ (possible to do full charge until 3 times when battery is full)
