FAQS

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

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.

Yes, the B660 SST can charge and discharge at the same time

Yes, the B660 SST has fan(s) that will automatically turn on to keep the unit from overheating.

When the product is charging, the charging indicator icon will flash, and the remaining time will be shown on the LCD screen.

Use a soft dry towel to wipe gently across all surfaces.

If your portable power station is not going to be used for extended periods of time, power off the unit and disconnect the AC adapter from the outlet. Store it in a safe dry place with a temperature of 32-104°F / 0-40°C and humidity within 90%. Every 3-6 months charge the product to at least 80% to protect its battery life.
