The OptiMate USB O-108v2 is a fully sealed in-line USB charger that connects directly to your bike’s SAE 2-pin battery lead and delivers up to 3300mA. With its 150 cm cable, you can route the USB port to the handlebar, frame, tank bag or pannier—wherever it’s most convenient to plug in your phone, GPS, camera or other USB device. Designed for outdoor vehicles, it includes automatic battery protection and standby behaviour to prevent draining your 12V AGM or LiFePO₄ battery when the engine is off, while still providing reliable charging in all weather conditions.
