The ER Power Bank 10000 mAh 10.5W 2x USB-A Black is a portable backup battery designed to keep your mobile devices charged while you are on the move. Featuring a capacity of 10000 mAh and a total power output of 10.5W, this power bank provides reliable energy for everyday commuting, travel, and emergency situations. Its slim and compact design makes it easy to carry in a backpack or bag, ensuring you have power whenever you need it.
This ER portable power bank is built with a robust body made of fire-resistant ABS and polycarbonate materials, offering durability against everyday wear and tear during transport. It features two USB-A outputs, allowing you to charge two mobile devices simultaneously. The integrated LED indicators provide a clear and direct overview of the remaining charge status at all times. Additionally, the device includes a convenient USB-C input for recharging the power bank itself and comes supplied with a practical 0.4-meter USB-A to USB-C cable supporting up to 2A.
This power bank may not be suitable for charging high-power demanding devices such as laptops or modern tablets that require fast charging protocols or power outputs significantly higher than 10.5W. Due to the shared output when using both ports simultaneously, charging speed for multiple connected devices will be slower compared to single-device usage.
To use the power bank, first ensure it is fully charged by connecting it to a USB power source using the provided USB-C cable and a compatible wall adapter. Monitor the charging progress through the LED indicators. Once fully charged, connect your mobile device to one of the USB-A output ports using an appropriate charging cable. The power bank will automatically begin supplying energy to your device. When charging two devices at the same time, the total output power of 10.5W is divided between both connected electronics.
For optimal battery health and longevity, store the power bank in a dry place at moderate temperatures, avoid exposing it to direct sunlight or moisture, and recharge the device at least once every three months if it remains unused for an extended period.
