FAQs
What kind of battery does the B4000 use?
The B4000 uses a solid-state Li-NCM 54A battery, which provides reliable and long-lasting power.
What devices can the B4000’s AC output port power?
The B4000's AC output ports can power most household appliances. However, before connecting an appliance, please make sure that the power of the appliance is within the rated power (4000W rated / 6000W max) of the power station to ensure safe operation.
How can I calculate how long the B4000 can power my device for?
You can check the charging time shown on the B4000’s LCD Screen. This can help you estimate the charging time of most appliances. For a more detailed calculation, see below:
You can calculate how long your device will last when powered by the B4000, by taking into account the limits imposed by the B4000's depth of discharge (95%) and inverter efficiency rate (90%).
(Power Station Capacity × Depth of Discharge × Inverter Efficiency) ÷ Device Rated Power
So for example, a 60W CPAP machine hooked up to the B4000:
(2611 Wh × 0.95 × 0.9) ÷ 60W = 37.21
So, in this case, the B4000 can power the CPAP machine for almost 37.21 hours.
Can the B4000 SST charge and discharge at the same time?
Yes, the B4000 SST can charge and discharge at the same time.
