Setup
Charging the Power Bank
Before first use, fully charge your power bank. There are two primary methods to recharge the device:
- Using the Built-in AC Wall Plug: Extend the foldable AC prongs located on the back of the power bank and plug it directly into any standard wall outlet. The LED display will show the charging progress. This method takes approximately 5 hours for a full charge.
- Using the USB-C Input Port: Connect a USB-C cable to the power bank's USB-C input port and plug the other end into a compatible power adapter (not included) or a computer's USB port. This method supports PD18W input and can fully charge the power bank in about 2.5 hours.
The LED digital display will indicate the battery percentage, allowing you to monitor the charging status accurately.
