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