What kind of battery does the B660 use?

The B660 uses a solid-state Li-NCM 16.2A battery, which provides reliable and long-lasting power.

What devices can the B660's AC output port power?

The B660'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 (660W rated / 900W max) of the power station to ensure safe operation.

How can I calculate how long the B660 can power my device for?

You can check the charging time shown on the B660’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 B660, by taking into account the limits imposed by the B660'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 B660: (602 Wh × 0.95 × 0.9) ÷ 60W = 8.58 So, in this case, the B660 can power the CPAP machine for almost 8.6 hours. If you need to power your device for longer than this calculation, you can check out some of our larger power stations.

Can the B660 SST charge and discharge at the same time?
