Power Box, Expands Electrical Capacity BLUETTI B210P Expansion Battery 2150Wh

Power Box / Expansion Battery Bluetti B210P Expansion Battery 2150Wh
An expansion battery engineered primarily for durability and flexibility in outdoor applications. Featuring an IP65 water- and dust-resistance rating, it withstands water spray, dust, and challenging environments exceptionally well (submersion or prolonged heavy rain exposure is not recommended), making it an excellent choice for adventurers, RV users, or anyone needing a reliable power source in all weather conditions.

The B210P features a LiFePO₄ (Lithium Iron Phosphate) battery that delivers superior safety and a long lifespan of over 3,000 charge/discharge cycles to 80% of original capacity. It also comes with an extensive 6-year warranty, reflecting confidence in product quality.

A major highlight of the B210P is its standalone power source capability—it can supply power on its own without connecting to a main power station. It features built-in DC output ports, including USB-A (18W), USB-C (100W), and a 12V car port, allowing you to charge smartphones, laptops, drones, or even run 12V mini-fridges directly.

When used as an expansion battery, the B210P connects with compatible BLUETTI power stations such as the AC200P L (supports up to 2 units) and AC240P (supports up to 4 units) to vastly expand system capacity, providing enough power to multiply runtime significantly. In addition, the B210P supports versatile charging options: AC wall outlet (via the separately sold T500 adapter), solar panels (up to 500W with built-in MPPT controller), and car cigarette lighter ports (via separately sold cable), making recharging easy wherever you are.
