Bluetti Charger 2 Launches with Dual Solar and Engine Charging

Bluetti has introduced the Charger 2, a new device designed to charge portable batteries using both vehicle engines and solar panels. Unveiled at CES 2026, the device solves a key limitation of the original Charger by accepting dual power inputs simultaneously.

The new unit features a dual-input architecture that accepts up to 600W from solar panels and 800W from an engine. This combination allows for significantly faster charging speeds, claimed to be 13 times faster than a standard car charger. The system is capable of managing multiple Bluetti power stations and expansion batteries, and it includes smart energy management to prioritize sources based on availability. Additionally, the device can function as a jump starter for vehicle engines.

For existing users, Bluetti offers a $99 upgrade kit available through February 7, which utilizes the same cabling as the previous model. New customers can purchase the Charger 2 for $349 during the promotional period, with the price increasing to $499 thereafter.

The Charger 2 represents a significant evolution in mobile power management, specifically targeting off-road enthusiasts and users with high energy demands. The device was developed to address the inability of the original Charger to utilize solar energy while driving. Previously, users could connect to a vehicle's alternator to charge batteries while on the move, but solar power remained a separate, unused resource during transit.

The new system introduces a dual-input architecture that allows for simultaneous power intake. According to the specifications, the device can accept:

• 800W of power directly from the vehicle engine
• 600W of power from connected solar panels
• Combined input for rapid charging capabilities

This integration ensures that users arrive at their destinations with fully charged batteries, regardless of whether they are driving or stationary. The system is designed to automatically detect and manage these sources, optimizing the flow of energy based on what is currently available.

Beyond simple power input, the Charger 2 incorporates advanced management features designed to handle complex power needs. Bluetti claims the device charges batteries significantly faster than the first model, boasting a charging rate that is 13 times faster than a standard car charger. This speed is achieved by leveraging the combined wattage of both engine and solar inputs.

The system is also scalable. It is capable of managing more than one Bluetti power station and expansion batteries simultaneously, catering to users with extensive power requirements. The internal logic is smart enough to identify the source of the energy and manage the inputs based on availability, ensuring efficient power transfer without manual intervention.

Furthermore, the device adds utility outside of charging portable batteries. It includes a feature that allows users to jump start their engine should the vehicle battery fail, providing an additional safety net for remote travel.

Bluetti has structured the release to reward loyalty to the original product while welcoming new users. For those who already own the Charger 1, the transition to the new model is described as "fairly painless." The Charger 2 utilizes the same cabling as its predecessor, allowing owners to swap the units without needing to rewire their setup or "get their fingers greasy."

To incentivize this upgrade, the company is offering the Charger 2 upgrade kit for $99. This promotional price is valid through February 7. Following this date, the upgrade option may no longer be available at this price point.

New customers looking to purchase the Charger 2 outright will pay $349 through the same February 7 deadline. After this promotional window closes, the retail price is scheduled to leap to $499. This pricing strategy suggests a limited-time opportunity to acquire the dual-input device at a lower cost.
