Review on MOTOPOWER MP0608 3.1 Amp Motorcycle Dual USB Charger with SAE to USB Adapter, Battery Monitor, Switch Control, LED Indicator – Prevent Battery Over-Discharge by Maurice Arnold

Reading the product description one would assume that the 3.1A rating means it is fast charge compatible, but that is not the case as the output voltage is only 5V and the fastest / fastest / The turbo requires a higher voltage to charge. ALSO 3.1 amps at 5v gives about 18 watts. 36W for full charger power. With 12V going through the fuse it's only 3 amps TOTAL for the charger at maximum power. So a 7.5A fuse with a blown fuse is total overkill, making it useless. In a nutshell. , it's just a regular USB charger with extra boosters on the ports that most devices can't use. I think extra amps are better than missing amps, but I'd rather have some sort of fast charge. I bought it for the form factor rather than because it's flat so it's easy to attach to my bike with 3M VHB tape. It's well done. Hasn't screwed me up almost 1 year later.
