Optimate USB O-108 KIT, Smart 3300mA in-Line USB Charger with Sleep Mode and Vehicle Battery Controller.

The OptiMate USB O-108KIT is a premium, comprehensive in-line USB charging kit designed to provide fast, reliable power to your electronic devices directly from your vehicle's battery terminals. Pairing our smart in-line USB charger with a heavy-duty permanent battery ringlet lead, this setup delivers a powerful 3300mA of charging current straight to your handlebar, tank bag, or pannier. Engineered with advanced microprocessor power control, it actively monitors voltage and includes a built-in standby mode to prevent your vehicle's battery from draining during long-term parking, guaranteeing you always have enough power to start your engine.

Features and Benefits

• Complete plug-and-play charging kit — Bundles the smart in-line USB-A charger with the heavy-duty O-31 permanent battery lead, offering a total combined routing distance of 200 cm (80″) from the battery compartment to your device mount.

• High-output single USB port — Delivers a true, stable 3300mA current output at 5V, enabling fast and efficient recharging of power-hungry smartphones, GPS units, action cameras, and tablets.

• Smart microprocessor battery protection — Features a low-input auto-off feature that cuts power if input voltage drops below 12.4V or after 1 hour of the engine being turned off, completely shielding your AGM or Lithium (LiFePO4) battery from total discharge.

• Integrated 2-LED battery monitor — Provides at-a-glance status verification of your parked vehicle's battery; dedicated LEDs blink every 5 seconds to confirm if your battery holds a charge greater than 50% and is ready to start the engine.

• Adaptive charge delivery — Automatically coordinates a charge confirmation "handshake" (including built-in Apple 1A handshake) to seamlessly adapt charging speeds to your specific device’s hardware limits.

• Weatherproof unique seal design — Features an innovative enclosed electronic housing with a form-fitting rubber cap and socket seal that squeezes tight against your inserted USB cable for safe charging in any weather condition.

• Permanent powersport ringlet terminals — The included battery lead features heavy-duty 1/4" (M6) ringlet eyelets tailored to bolt cleanly onto powersport battery posts, protected by an inline 10A fuse.

• Rated for –20 °C/–4 °F — Built with premium SPT-1 rated cabling designed to survive seasonal outdoor elements, keeping the insulation pliable and crack-resistant at below-freezing temperatures.
