This fast charging power bank from Joyroom has a 20,000mAh capacity that will keep you charged on leisure or business trips. The power bank has dual built-in charging cables, as well as a lanyard for better grip, making charging easier on the go. It has 2 input ports and 4 output ports, allowing it to charge 4 devices simultaneously. With its digital display, it shows the exact remaining power in real time. The 22.5W super fast charging supports PD3.0, QC3.0, Samsung AFC and Huawei SCP/FCP fast charging protocols. The power bank also features a low-power mode, a feature designed to charge low-power devices such as Bluetooth headphones, smartwatches, and fitness trackers. This mode prevents the power bank from going into sleep mode by delivering a steady, low current, which would otherwise cause charging to stop due to the device's low power consumption.
