Sae to USB Optimate Adapter

Weatherproof power on any ride. This OptiMate SAE-to-USB charger lets you power a phone, GPS, or camera right from your bike’s battery—then route the sealed USB port to your handlebar, tank bag, or pannier for easy access in any weather.

The fused ring-terminal lead connects directly to your battery, while the in-line module delivers up to 3.3A of smart, device-safe charging. Built-in protection monitors your parked battery and automatically shuts USB output off to prevent drain, then resumes when the engine fires. An LED status light helps confirm your battery is “start ready.”
