B210
Storage for a compatible host, with useful standalone DC outputs.
Confirm exact host compatibility, included cables, price and dispatch date with BLUETTI.
Why this component
Expansion battery.
B210 adds an energy reserve to an AC200L or AC240 setup. It is most relevant when an existing system runs out of stored energy before its inverter runs out of power.
What to check before buying
For an overnight refrigerator, first establish the host’s measured daily energy use. Extra battery capacity can extend the reserve; it does not lower the appliance’s demand or increase the host inverter rating.
Connections & compatibility
Check compatible equipment and cables
| Part of the plan | What to verify |
|---|---|
| Host | AC200L or AC240; confirm the current host manual. |
| Cable | AC200L requires an additional compatible connection cable. Verify the exact cable in the cart. |
| AC loads | Use the host inverter; B210 itself has no AC outlet. |
| Outdoor use | Protect connectors and observe the manual. An IP rating is not permission to submerge the pack. |
This table identifies the checks that matter; it is not approval of a custom installation. Use the exact current model manuals and manufacturer confirmation where a connection or operating mode is unclear.

Read this before ordering.
Do not select an expansion battery only because the plug looks similar. Host models have different expansion limits and cable requirements. Ask BLUETTI to confirm the complete bill of materials for your exact AC200L or AC240 configuration.
Check what’s included
Confirm the exact product quantity, host-specific cable or adapter, required mounting parts and warranty conditions. An ecosystem photograph or a shared brand name does not establish that every shown component comes in the selected offer.

Before you choose
Can B210 run an AC appliance by itself?
No. Its standalone outputs are DC/USB. An AC appliance needs the compatible host and its inverter.
