Modern USB devices require stable power to recharge fast. Modern smartphones (iPhone, Android, etc.) now have batteries of around 3Ah (3000mAh). A lithium motorcycle battery capacity range between 2Ah to 5Ah with Lead-acid (AGM / STD) batteries 2-3x more than that. Even though it has more capacity, if discharged below 50% the vehicle may struggle to start.

OptiMate USB chargers incorporate unique power control that will protect the vehicle’s battery, ensuring there is always sufficient power to start the engine.
