This high-capacity, fast-charging power bank is 49% off right now
The USB-C port doubles as an input, allowing you to recharge the power bank itself at up to 60W (which brings it from zero to full in 100 minutes). Alternatively, you can recharge using the Micro-USB port (but that one has a max throughput of 18W). And the small LED display shows you exactly how much battery is left for charging.
