Fast On-The-Go Charging—1kWh in 1.5 Hours

Charge your portable power station efficiently using your vehicle’s surplus energy. Delivers 1kWh in just 1.5 hours—up to 8× faster than traditional 100W car chargers. Built-in DC-DC converter ensures continuous, rapid replenishment while you drive.

Three Versatile Charging Modes

Use your car's alternator to charge your portable power station with 800W.

On-the-Go Power for every Journey

Auto On/Off

Powered by an intelligent voltage monitoring algorithm, 800W Alternator Charger automatically starts charging your power station whenever your car starter battery allows—even when parked. Enjoy worry-free charging with smarter, more reliable control than old-fashioned vibration sensors.

Made for Mega Series & Guardian Series

Engineered to work seamlessly with OUPES Mega and Guardian power stations, this 800W Alternator Charger delivers optimized charging profiles, stable output and simple plug-and-play connections.

Triple Safety Protection

Drive without worry: the charger protects your vehicle battery from over-discharge, features auto on/off and multiple circuit safeguards for safe operation, and lets you fine-tune output voltage to match your power station—keeping your SUV, pickup or RV ready to start and your gear safely powered.

Smart Power in Your Hands

Use the Cleanergy app to monitor charging in real time and fine-tune voltage with a tap, keeping every amp stable and smooth—whether you’re driving your SUV, towing with a pickup, or relaxing inside your RV.

Easy to install

*For safety, wear goggles and insulated gloves, and have a professional install or supervise if possible.

Step 1: Turn off the vehicle, charger and power station before installation to prevent short circuits. Connect the fuse cable to the vehicle battery terminals (+/–), then plug the other end into the Alternator Charger.
