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 -4℉.

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.

Never Run Out of Power

AC500 powers your devices like a gas generator, but without any fuel costs, noise, and pollution,
making it safe enough to use next to you whether you're at home, pitching a tent, or trying an RV road trip.

Pricier than B300

The battery is certainly good. In our case, we have no use for more than 2 or 3 batteries, so we don't benefit from the increased number of batteries that can be connected together. Moreover, the extra cost related to the self-heating feature isn't useful in our case either. So we only pay the higher price tag as this battery is the only one compatible with the AC500 - which offers the extra power we need compared to AC300.
