EPS: Emergency Power System.
Once you have connected the mains and the AC input port of the EPS via the AC charger cable, you can use the AC output port of the EPS to power your unit (at this point the AC power comes from the mains, not the EPS battery). In the event of a sudden loss of mains power, the EPS can automatically switch to battery mode within 20ms. Since this is a non-professional UPS function, it does not support 0ms switching. Do not connect to equipment with high uninterruptible power requirements such as data servers and workstations. Please test several times to confirm compatibility before use and it is recommended to connect to only one device. Do not use more than one unit at a time to avoid triggering the overload protection. Failure to follow these instructions may result in equipment failure or loss of data for which we cannot be held responsible.

Battery Power Indicator
When the product is being charged, the orange circle around the battery percentage will light up in sequence. When charging other devices, the orange circle will stay on.

Low Battery Indicator
When the battery is less than 20%, the Low Battery Indicator will stay on. When less than 5%, the Low Battery Indicator will flash. When it is being charged, the Indicator will be off.

Energy Saving Mode
To avoid forgetting to turn off the output which results in battery consumption, the product turns the Energy Saving Mode on by default. This occurs when no device is connected or the connected device is less than or equal to a certain value. (Refer to the table below for more details), the device will automatically turn off all outputs after 12 hours.
| Output Output | Power Defaults | |
| AC Output | ≤25W | All outputs turned off automatically after 12 hours |
| USB Output | ≤2W | |
| Car Output | ≤2W |
