Acefast 10,000mAh 22.5W Power Bank, LED Display, Fluorescent Yellow

Black power banks disappear into the bottom of a rucksack. This one is fluorescent yellow, which sounds like a small thing until you are feeling around a kit bag on a dark morning and find it first time. Underneath the colour it is a straightforward 10,000mAh pack built for daily carrying.

The USB-A port pushes up to 22.5W and the USB-C port up to 20W, so a modern phone gets a proper fast top up rather than a trickle. Use both at once and output steadies at 5V 3A. Charging the pack itself runs through USB-C at 18W, with Power Delivery, Quick Charge, Adaptive Fast Charging and FCP all recognised.

An LED display gives the charge level as a number and shows what is going out while it works, so you know before leaving the house whether it needs another hour on the mains. The housing is flame retardant PC, with protection built in against overcurrent, overvoltage and short circuits.
