Charmast Power Bank with Built in Cables X 4, 10000mAh USB C Battery pack 6 Outputs 3 Inputs with LED Display Type C Powerbank Portable Charger - brand:charmast - mpn:W1148

This power bank features 6 output ports/cables, allowing you to charge up to six devices simultaneously, depending on which built-in cables and USB ports you utilize.

The built-in cables cover Micro USB, USB-C, and Lightning (for iPhones), making it compatible with a wide range of smartphones, tablets, and other small electronic devices.

The LED digital display will show 100% when the power bank is fully recharged. You can monitor the charging progress on the display.

While it has USB-C output, the 10000mAh capacity and power output are generally not sufficient for most laptops, which typically require higher wattage and capacity power banks.

Recharge time varies depending on the input method and charger used, but typically it takes several hours for a full recharge from empty.

Most 10000mAh power banks are generally allowed on flights, but it's always recommended to check the specific regulations of your airline before traveling.

Ensure the power bank has sufficient charge by checking the LED display. Verify that the built-in cable or your external cable is securely connected to the device. Try using a different built-in cable or port.

Confirm that the charging cable and power adapter being used are functional and compatible with the power bank's input ports. Try a different input port on the power bank or a different charging cable/adapter.

Try recharging the power bank. If the issue persists after a full charge, there might be an internal issue with the display.

Ensure only one or two devices are being charged at a time, as multiple devices share the power output. Avoid charging the power bank simultaneously while charging other devices, as this can also reduce efficiency.
