Expandable Battery Pack

B300S has a 3.072Wh capacity and lasts 3.500+ cycles to 80% of its original capacity. Hook up 6 B300S packs with AC500, and you'll get a massive powerhouse with 18.432Wh, enough to power up your RV, off-grid life, and get you through a severe power outage.

Responsive Even in the Cold

Waking up electronics on a freezing day may be time-consuming. But with the Self-heating Function, B300S will automatically heat up the battery to ensure it can work actively and smoothly as usual.

Note: Self-heating Function won't be activated if the ambient temperature is under -20°C.

Standalone Power Source

More than an expansion battery pack, B300S can be used as a standalone power source as it features versatile outputs - 100W USB-C, 12V/10A cigarette lighter, and 18W USB-A to feed your smartphones, laptops, fans, lights, refrigerators, and more.

Blazing Fast Recharging

Faster is always better. Charge your B300S in 4 hours* at the maximum of 1.000W input rate by 1.000W Solar input* or 500W adapter with 500W solar input.

* The data is for reference only.
* The D050S DC charging enhancer is required.

Flexible Recharging

BLUETTI B300S takes up to 500W AC, solar, or car charging.
