PRECAUTIONS

• Some USB cables that are not compatible with the power bank or can't be used should be avoided, instead, choose or purchase the charging cable of the same mobile brand to get adequate speed.
• Do not use two charging cables simultaneously in both Type-C ports.
• When the power bank can't charge digital products, please check whether the charging cable and connectors are connected properly or change the cable. After digital devices are fully charged, please unplug the charging cable timely to avoid power loss.
• Because of the high charge and discharge current, please choose good quality charging cable and connectors.
• Please make sure the power bank is fully charged when using it for the first time. Make sure that the product is fully charged at least once in two or three months.
• During charging the power bank, please unplug the cable within 30 minutes when the power bank is fully charged.
• While using output through a single port, the powerbank delivers maximum power but if dual or more ports are used at the same time, then the power bank will divide power into two or three.
• In single port usage, the Power bank will operate in only one parameter whether QC or PD and will provide the output ratio mentioned.
• If all the ports are used in a single phase, then the Power Bank will work on basic parameters and the current will be divided into all the ports.
• It’s always suggested to discharge the powerbank completely before recharging to get enhanced battery backup. Frequent top-ups after minimal use may reduce long-term performance.
