USB C Power Bank with Digital Display and Two Capacity Options

The window on the front gives you a number, which is the only thing you want from a power bank at seven in the morning

Four little bars tell you nothing useful. A figure tells you whether tonight is a charging night. This one reads the charge as a percentage in a small window on the front, with a legend printed underneath naming the supported protocols, and that single detail changes how you use it.

The body is 141 by 67 by 27 mm, which is a coat pocket rather than a jeans pocket, in a lithium polymer pack behind a PVC shell. Along the top edge sit USB-A and USB-C ports and a power button. With two way charging, the same row takes power in at 22.5 W and gives it back out to a maximum of 120 W under PD 2.0.

Key Benefits

• A charge figure, not a guess The percentage display tells you what is left before you leave the house rather than halfway through a journey.
• Both connectors on one edge USB-A and USB-C ports beside the power button, so old cables and new ones both work.
• Fills and empties through the same row Two way charging, at 22.5 W in and up to 120 W out under PD 2.0.
• Two capacities, one shape The dropdown carries a smaller and a larger pack in the same 141 x 67 x 27 mm body.
• Two plain finishes Black or white, with the capacity and protocol printed down the side rather than hidden in a manual.

Best for: a bag that already carries a phone, earbuds and a watch, long train days, and anyone who has run out of charge once and does not intend to again.

Why It Works

Most packs of this size treat the output as a single number on the box and leave you to discover the truth in an airport. Putting a percentage on the front and the supported protocols on the case is a small piece of honesty that pays off every day, because you can see the state of the pack and the ports you are dealing with without opening anything. The two way charging matters for the same practical reason: one cable goes in the top whichever direction the power is flowing.

Quick Product Facts: 141 x 67 x 27 mm; lithium polymer cell in a PVC shell; digital percentage display; USB-A and USB-C ports plus a power button on the top edge; two way charging; input 5V at 22.5 W; maximum output 120 W; PD 2.0 protocol; rated capacity 34200 mAh for the larger option; two capacity options and two finishes, black and white; supplied with a USB cable and a manual, no mains adapter.

How It Fits Your Routine

It lives in the outside pocket of a bag, charged on a Sunday evening and checked with a glance at the window rather than a guess. On a travel day it is the reason a phone still works at the far end.

At a desk it becomes the thing that charges the earbuds case and the watch while the laptop has the wall socket. Both connector types are on the same edge, so nothing needs an adapter.

Treat it like any lithium pack. Keep it out of a hot car and away from a radiator, do not carry it loose in a bag with keys and coins, and stop using it if the shell swells or deforms.

FAQ

Can I take it on a plane? That is a question for your airline, not for us. Carriers limit lithium batteries by watt hour rating. Check your carrier's published limit before you fly, and never put a power bank in checked baggage.

Is the larger option really 57000 mAh? The rated capacity of that option is 34200 mAh, which is the figure that describes what the pack can actually deliver. The headline number is the cell figure.

Will one device get the full 120 W? Unknown. 120 W is the maximum output, so a single phone or laptop will not necessarily see that figure on its own. What it will do is negotiate under PD 2.0 with whatever you plug in.

Why do the photographs show two different units? Because they do. Most images show a body printed 120W and one shows a body printed 22.5W, which is a different model from the same family. Only the options on this page can be ordered, so pick the capacity from the dropdown.
