1. What battery does the product use?
   The product uses a solid state Li-NCM 16.2A battery.

2. What devices can the product’s AC output port power?
   The portable power station’s AC output ports can power most household appliances. Before connecting an appliance, confirm the power of the appliance to ensure that the sum power of all loaded appliances is lower than that of the rated power (2000W rated/3000W max)

3. Capacity
   Multiply the capacity of the portable power station x 0.95 x 0.9 / device rated power. The 0.95 and 0.9 are DOD (depth of discharge) and inverter efficiency values. Let’s use the B660 SST and a 60W CPAP machine as an example. The calculation would be 602wh x 0.95 x 0.9 / 60W = 8.5 hours.

4. Can the B2000 SST charge and discharge at the same time?
   Yes, the B2000 SST can charge and discharge at the same time. Please keep the equipment on a level surface during use, charging, and discharging.

5. Does the B2000 SST have cooling fan(s)?
   Yes, the B2000 SST has fan(s) that will automatically activate to keep the unit from overheating.

6. How long can the product charge my devices?
   Check the charging time shown on the product’s LCD Screen. This can help you estimate the charging time of most appliances.

7. How do I know if the product is charging?
   When the product is charging, the charging indicator icon begins to flash and the remaining time will be shown on the LCD screen.

8. How do I clean the product?
   Use a soft dry towel to wipe gently across all surfaces.

9. How do I store the product?
   If the 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 product in a safe dry place with a temperature of 32-104°F / 0-40°C and a humidity within 90%. Every 3-6 months charge the product to 80% to protect battery life.
