OPTIMATE Fast charging SAE-to-USB - O-100v3

The OptiMate USB O-100v3 is a portable, compact SAE-to-USB charger designed for safe, fast charging of any USB device directly from your motorcycle, scooter, ATV and quadbike’s battery. It plugs into an industry-standard 2-pin SAE battery lead and delivers up to 2400mA @ 5V, ideal for keeping your phone, GPS, camera or any other device powered while you ride.

Despite its small 8 cm size, the O-100v3 includes smart battery protection and monitoring: it automatically switches off to prevent draining your AGM or LiFePO₄ battery when the engine is off, then starts charging again when voltage rises as the engine runs. A 2-LED monitor indicates whether your battery is ‘start ready’, and the weatherproof USB socket and rideproof cap make it truly fit-and-forget in any weather.
