Promate 10000mAh Portable Power Bank with Built-In 20W USB-C In/Out Foldable Connector and 20W Lightning Foldable Connector, Fast USB-C Charging Port, LED Display - Purple / POWERUP-10DUO.PURPLE / POWERUP-10DUO.PURPLE

The Promate POWERUP-10DUO in purple is a 10000mAh power bank with two foldable connectors built into the body, one 20W USB-C and one 20W Lightning. A separate fast USB-C charging port and an LED display complete the pack, so it charges an iPhone or an Android phone with nothing else in the bag.

The foldable USB-C connector is part of the pack and delivers 20W. It swings out to meet an Android phone or a tablet and folds away afterwards, and at 20W it is doing genuine fast charging rather than the slow trickle that built-in connectors used to imply.

A second foldable connector handles Lightning at 20W, so an iPhone plugs directly into the bank with no cable involved. Carrying both connector types is the reason for the DUO name, and it is what stops a mixed household hunting for the right lead every time a phone runs low.

The built-in USB-C connector works in both directions, so the same fold-out arm that charges a phone is what refills the power bank itself. One connector covering both jobs is exactly what lets the pack travel with no separate charging cable packed alongside it.

A fast USB-C charging port sits on the body alongside the fold-out connectors and takes an ordinary cable. That covers a device the built-in arm cannot reach comfortably, and it means a second device can be plugged in without disturbing whatever is already attached to the pack.

An LED display reports the charge state as a figure you can read rather than a row of dots to interpret. That reading is what decides whether you top a phone up now or leave it, and it is the difference between arriving somewhere charged and arriving somewhere flat.

Capacity is 10000mAh, the size most people settle on for a bank that lives in a bag daily rather than one reserved for trips, and this version wears a purple finish. A coloured pack is also far easier to pick out of a dark bag or off a table where several identical black bricks are charging.
