Common questions about manuals, registration, and support for this brand.
When charging the power bank, the LED digital display indicates the exact battery level. Once the display reads '100%', the battery is fully charged.
Check if the connection between the charging cable, adaptor, and socket is loose. If the LED display gets stuck on a certain value and won't fully recharge, unplug the cable and press and hold the power button for 30 seconds until the display flashes to reset it.
YILANS primarily handles support through Amazon. You can reach their customer service team by logging into your Amazon account, going to 'Orders', finding the YILANS purchase, clicking 'Contact Seller', and sending a description of your issue.
Standard warranty periods typically run for 3 months from the date of purchase, according to the official user manual. For specific unit questions, please check your Amazon order details.
