3. Product Introduction

The CHARGER 1 is your go-to for fast charging BLUETTI portable power stations using extra power from your car's alternator. It fits perfectly in cars, SUVs, and RVs and can replenish your power station up to 5 times faster than regular car outlets thanks to its built-in booster module. Plus, it smartly detects your car battery's voltage to prevent drainage, so you'll never be left without power on your adventures.
