For outdoor enthusiasts venturing off-road, harnessing a vehicle's engine to recharge portable batteries offers a practical solution, leading Bluetti to introduce its initial Charger model. This device connects directly to the alternator, pulling in power during drives to ensure batteries reach campsites fully charged. However, owners with rooftop solar panels previously lacked the ability to integrate that renewable energy source. Addressing this gap, Bluetti revealed the Charger 2 at CES 2026, designed to draw from both the engine and solar arrays concurrently.
According to Bluetti, the Charger 2 features a dual-input system capable of handling 600W from solar panels and 800W from the engine. This combined input enables much quicker battery recharging compared to the original version, with the company stating it's 13 times more efficient than a typical automotive charger. The unit also supports charging multiple Bluetti power stations and additional battery packs for expanded energy requirements. Its intelligent controls detect and prioritize power sources based on their current output, and it includes functionality to assist in starting a vehicle engine if necessary.
Owners of the first-generation Charger can upgrade seamlessly by swapping out the older device for the new one, as it employs identical wiring connections that avoid any need to handle oily components. In appreciation of existing customers, Bluetti offers the upgrade kit at a discounted rate of $99 until February 7.
New buyers can purchase the Charger 2 for $349 until February 7, after which the price will increase to $499.
