Yes. It comes with 100W USB-C, USB-A, and a 12V car socket that provides power for phones, laptops, car refrigerators, and more.

3How many B300s can I connect to an AC300 or AC200MAX?

AC300: up to 4 B300s for a capacity of 12288 Wh.
AC200MAX: up to 2 B300s for 8192 Watt-hours of power.

4Does the B300 support program management?

Connect it to the AC300, pair them with the BLUETTI App, and you can control your system anytime, anywhere.

5What is the maximum input charging power of the BLUETTI B300?

700 W max. with the optional DC charger D050S*.
* Sold separately

6Can I use a car cigarette lighter or lead-acid battery to charge the B300?

Yes, you need the BLUETTI D050S DC Charging Enhancer*.
* Sold separately

7Can I use third-party solar panels to charge BLUETTI B300?

Yes, if the characteristics of the solar panels correspond to

1) General voltage: 12-60 В

2) Total power: 200W Max.

3) Plug in the MC4 connectors.

8Can I charge and discharge at the same time?


9Can I use or charge the B300 in sub-zero temperatures?

Temperature ranges for the B300:
charging: 0-40 ℃ (32-104 ℉);
Range: -20-40 ℃ (-4-104 ℉);
Storage: -20-40 ℃ (-4-104 ℉).
Technically, it can power electrical devices in such situations, but please do not charge it.

10How long can my device work?

Operating time = Battery capacity × DoD × η ÷ Device rated power DoD refers to the depth of discharge, and η is the efficiency of the local inverter.
For the B300, DoD and η are 90%. If you use a 100W light bulb, the operating time will be:
3072 W-h × 90% × 90% × 100 W ≈ 25 hours
. Note: the above data is for reference only.

11Is the B300 waterproof?

No. Also, please DO NOT store it in a humid environment for a long time.

12Can I replace the built-in battery?
