The BLUETTI B210P is a 2150Wh LiFePO4 expansion battery designed for the BLUETTI AC240P power station: the connecting cable comes in the box, and the AC240P stacks up to four batteries for as much as 10443Wh. It also expands the BLUETTI AC200P L, taking it from 2304Wh to 4454Wh with one battery or 6604Wh with two, with a connecting cable sold separately. Its IP65 water and dust resistant shell and 3000 cycle battery suit RV trips, off-grid living, and home backup where more stored energy is the missing piece.
The B210P is also a useful power source on its own, with a 100W USB-C port, an 18W USB-A port, and a 12V/10A car-style outlet for phones, laptops, and 12V gear. Recharge it from up to 500W of solar with the included cable, from the wall with BLUETTI's T500 adapter (sold separately), or from a car outlet. If you're unsure which host, cable, or setup fits, we're happy to help before you buy. BLUETTI B210P Specs:
