Review on 📱 MOTOPOWER MP0609EA: Waterproof Motorcycle Dual USB Charger Kit for Phone, Tablet, GPS - 3.1Amp by Michael Hellewell

I can leave it plugged in all the time, even days when the bike is off because I have a ST1300 with a large battery. A smaller bike with a smaller battery will require you to turn it off daily when the bike is off. Otherwise I give my ST1300 two USB sockets. I attached it with velcro to the inner wall of the right compartment, very handy for phone, gps, GO-Pro etc. Good reliable product, have been using it for a few months.
