Review on iMESTOU 5V 2.1A Motorcycle Dual USB Phone Charger Adapter w/ ON/Off Switch | Waterproof Ports | Smart Charging Socket | Fused | 12V/24V Compatible | ATV UTV Lawn Mower, etc. by Kenyatae Tillo

You get what you pay for, that's what comes to mind with this USB adapter. It's far from waterproof. The cheap rubber grommets don't fit properly on the outlets and the fit around the handlebars is mediocre at best, even with the rubber grommets provided. not in use, it has a built in fuse, the cable is long enough and it works to charge my phone while i use it for gps and music for my helmet comm device on the go.
