Ultrapower UP400AC Charger review, comparison to Graupner Ultra Duo 60 and Team Orion

How to charge all those miniquad batteries? I use 3 different Dual-Chargers - see their options and features here. Ultrapower UP400AC Duo - buy: http://bit.ly/2cMntmo
Tech specs: http://bit.ly/2cEWM5g

Graupner Ultra Duo Plus 60   (289€) http://bit.ly/2d0x36Z
Team Orion Advantage Touch  (215€) http://bit.ly/2cqGs5b
buy: http://bit.ly/2czEXj5

DONT LET YOUR CHARGER UNATTENTED! make sure to always be around, have more chargers to charge more efficiently, USE A SMOKE ALERT in that room, have a fire extinguisher...
