BLUETTI B210P Expansion Battery | 2150Wh
Overview
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.

Note: The B210P has no 230V outlets of its own; for mains appliances it pairs with a compatible BLUETTI power station, sold separately. The included expansion cable fits the AC240P. Connecting to the AC200P L needs a different cable, sold separately.
More Capacity for Your Power Station
The B210P is made first for the BLUETTI AC240P: plug in with the included expansion cable and stack up to four batteries, taking a system as high as 10443Wh. On the AC200P L, one B210P lifts total capacity from 2304Wh to 4454Wh and a second reaches 6604Wh, enough to run a fridge, lights, and devices through a long weekend off-grid or a serious power cut at home.
A connecting cable for the AC200P L is required and sold separately.
Built Tough with IP65 Protection
The B210P wears an IP65-rated shell, sealed against dust and able to shrug off rain showers and splashes at the campsite, on the boat, or beside the van. Its LiFePO4 battery is rated for 3000+ charge cycles, and BLUETTI backs the B210P with a 6-year warranty.
Take It Beyond the Driveway
Parked up at the lake or the back of the farm, the B210P keeps the essentials running long after dark. Stack it under a compatible BLUETTI power station for 230V appliances, or run 12V and USB gear straight from the battery itself.
A Standalone Power Source Too
The B210P is more than an add-on. Its own DC panel carries a 100W USB-C port, an 18W USB-A port, and a 12V/10A cigarette lighter outlet, so it can charge phones, laptops, drones, and camera batteries, or run a 12V fridge, without a power station attached.
Three Ways to Recharge
Fill the B210P from up to 500W of solar with the included solar charging cable in about 4.5 hours. From the wall, BLUETTI's T500 adapter (sold separately) charges it at up to 470W in about 4.7 hours. On the road, it tops up from a 12V or 24V car outlet with BLUETTI's car charging cable, also sold separately.
What's in the Box
Pairs Well With
Out of the box the B210P pairs with the BLUETTI AC240P power station via the included expansion cable, stacking up to four batteries; the AC240P is not currently in our range. From our store it pairs with the BLUETTI AC200P L Portable Power Station: one battery lifts the AC200P L from 2304Wh to 4454Wh and a second takes it to 6604Wh, with the connecting cable sold separately. If you're unsure which cable or setup fits, we're happy to help before you buy.
Frequently Asked Questions
Which BLUETTI power stations work with the B210P?
The B210P is designed for BLUETTI's AC240P, which takes up to four units using the expansion cable included in the box, though that model is not part of our current range. It also expands the BLUETTI AC200P L, which accepts up to two batteries with a connecting cable that is sold separately. If you're unsure what fits your setup, we're happy to help before you buy.
Can I use the B210P on its own?
Yes. The B210P works as a standalone DC power source with a 100W USB-C port, an 18W USB-A port, and a 12V/10A car-style outlet, so it can run phones, laptops, and 12V gear without a power station. It has no 230V outlets of its own. For mains appliances, pair it with a compatible power station.
How do I recharge the B210P?
Three ways. Solar uses the included cable and accepts up to 500W, filling the battery in about 4.5 hours. From the wall, BLUETTI's T500 adapter (sold separately) charges at up to 470W and takes about 4.7 hours. It also charges from a 12V or 24V car outlet with BLUETTI's car charging cable, also sold separately.
Can I charge it with third-party solar panels?
Yes. Panels need an open circuit voltage between 11V and 60V and MC4 connectors, and the B210P accepts up to 500W of solar input. BLUETTI advises against mixing different types of solar panels in the same array.
Is the B210P waterproof?
Not fully waterproof, but well protected: its IP65 rating means it is sealed against dust and stands up to low-pressure water jets from any direction. Rain showers and splashes are fine. Do not submerge it, and store it somewhere dry.
Can it charge and discharge at the same time?
Yes. The B210P supports pass-through charging, so it can top up from solar or the wall while it runs your devices.
Does it work with the BLUETTI app?
Yes, through a host power station. Connect the B210P to the AC200P L, pair the system with the BLUETTI app, and you can monitor and control the combined setup from your phone.
