* OptiMate USB deliver a powerful and stable charge required by modern USB devices. The O-100 delivers 2400mA while all the other models deliver 3300mA of charge capable of recharging any device quickly.
* Modern smartphones now have batteries with capacity almost the same as a small motorcycle's lead-acid battery or a larger motorcycle's lithium battery. Charging that phone from the parked vehicle's battery may drain it too low for the engine to start. Not with OptiMate USB! These chargers incorporate unique microprocessor power control that protects the vehicle's battery, guaranteeing there will always be sufficient power to start the engine. You can leave an OptiMate USB hooked up in a parked vehicle for months, it will not drain the battery.
* OptiMate USB chargers include a built-in standby mode that turns off USB charging one hour after the vehicle was parked and engine was turned off, preventing your vehicle's LFP (LiFePO4) or AGM (Pb) battery from draining further.
It will also turn off immediately if the voltage drops very low (i.e. below 12.4 V) during starting of the engine.
* OptiMate's O-100 and O-108 USB chargers include a built-in battery monitor that indicates your LFP (LiFePO4) or AGM (Pb) is ready to start the vehicle. Check your stored vehicle's battery status at-a-glance; the LED corresponding to battery type blinks every 5 seconds.
* The OptiMate USB range includes models with USB-A charge ports and USB-C charge ports.
