How should I store and maintain the product?
1. To preserve the battery lifespan, recharge it to 100% after every use.
2. Turn on Power Saving Mode and turn off all the buttons on PowerHouse.
3. We recommend recharging it 100% every month.
What should I do before using for the first time and what do I need to pay attention to?
Charge your portable power station to activate the battery before using for the first time. Do not use with CPAP overnight and in Power Saving mode.
Why does the power station’s battery drain even when no devices are connected?
When the AC and car socket control buttons are turned on, there will be a certain amount of no-load power consumption. To avoid this, make sure the control buttons are turned off, or turn on Power Saving mode when not in use.
