- Incompatible with appliances that require more than 200W input such as microwave, electric grill, refrigerator, electric vehicle, air compressor and more.
- Do not use with CPAP overnight and in power saving mode.
-The power station supports pass-through charging while connected via a vehicle output or AC outlet.
- Please remove the protective film on the screen before using it for the first time.
- If you feel that the battery drains fast when used for the first time, it is because the display information of the remaining power is inaccurate when the product is activated for the first time. The power remaining will automatically calibrate by discharging the battery to 1% and then recharging it to 100%.
