tax incl.
The Bluetti B300S Expansion Battery is a powerful addition to the Bluetti Power Stations, with an impressive capacity of 3072 watt-hours. This expansion battery offers reliable and extended power supply for various electronic devices, thanks to multiple output ports, including AC, DC, and USB. Ideal for users who require substantial energy storage, whether for prolonged outdoor activities, emergency power during power outages, or as part of an off-grid power system.
Flexible charging
The BLUETTI B300S requires up to 500W of AC power, solar power, or car charging. Combine AC with solar or car power, and you can recharge the B300S in less than 3.5-4 hours with a maximum input power of 1000W.
* The D050S DC charging amplifier is required.
Versatile power source
You can power your smartphones, laptops, fans, lamps, refrigerators and more with dedicated outputs: 100W USB-C, 12V/10A cigarette lighter, and 18W USB-A.
Responsive, even in the cold
Waking up electronics on a freezing day can be time-consuming. But with the temperature adjustment feature, the B300S automatically warms up to keep working smoothly and efficiently as usual.
Expandable battery pack
As the companion battery pack for the AC500, the B300S has a capacity of 3072 Wh and can last over 3500 cycles to 80% of its original capacity. Connect 6*B300S to the AC500 and you get a powerhouse of 18432 Wh, enough to get you through a serious power outage.
Never run out of power
B300S powers your appliances like a gas generator, but without the fuel costs, noise and pollution.
