FAQ

What kind of battery does the B330 use?

The B330 uses a solid-state Li-NCM 16.2A battery, which provides reliable and long lasting power.

What devices can the B330's AC output port power?

The B330'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 (330W rated / 480W max) of the power station to ensure safe operation.

How can I calculate how long the B330 can power my device for?

You can check the charging time shown on the B330's ICD 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 B330, by taking into account the limits imposed by the B330's depth of discharge(95%) and inverter efficiency rate (90%).

(Power Station Capacity x Depth of Discharge x Inverter Efficiency) + Device Rated Power

So for example, a 60W CPAP machine hooked up to the B330:

(241Wh x 0.95 x 0.9) + 60W = 3.43 Hours

So, in this case, the B330 can power the CPAP machine for almost 3.5 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 B330 SST charge and discharge at the same time?

Yes, the B330 SST can charge and discharge at the same time.

Does the B330 SST have cooling fan(s)?

Yes, the B330 SST has fan(s) that will automatically turn on to keep the unit from overheating.

How do I know if the product is charging?

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

How do I clean the product?

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

How do I store the product?

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%. Charge the product to at least 80% every 3-6 months to protect its battery life.
