BLUETTI B300S takes up to 500W AC, solar, or car charging. Combine AC with solar or car input, you can top up B300S in less than 3.5-4 hours with a maximum of 1,000W* input rate. *The D050S DC charging enhancer is required.
Versatile Power Source
You can power your smartphones, laptops, fans, lights, refrigerators and more with specific outputs-100W USB-C, 12V/10A cigarette lighter, and 18W USB-A.
Responsive Even in the Cold
Waking up electronics on a freezing day may be time-consuming. But with the Temperature Adaptive Function, B300S will automatically heat up to work actively and smoothly as usual.
Expandable Battery Pack
As the companion battery pack to AC500, B300S has a capacity of 3,072Wh and lasts for 3,500+ cycles to 80% of its original capacity. Hook up 6*B300S with AC500, you'll get a powerhouse with 18,432Wh, enough to get you through a severe power outage.

Temperature ranges for B300S are:
Charge: 0-40℃ (32-104℉);
Discharge: -20-40℃ (-4-104℉);
Storage: -20-40℃ (-4-104℉).
Technically, it can power electrical devices under such situations, but please avoid charging it.
Running time = Battery capacity × DoD × η ÷ Device rated power DoD refers to Depth of Discharge and η is local inverter efficiency.
For B300s, both DoD and η are 90%. If you run a 100W light bulb with it, the running time will be:
3,072Wh × 90% × 90% ÷ 100W ≈ 25hrs
Note: The above data is for reference ONLY.
No. Also, please do NOT store it in a humid environment for a long time.
No. If the battery pack is faulty or even dead, please contact BLUETTI Customer Service.
Sure, please follow BLUETTI Support on YouTube.
1) Current capacity: 130A for B300S while 75A for B300.
