Ugreen Uno 10,000mAh 30W power bank review
The Ugreen Uno 10,000mAh 30W power bank offers multiple ways to keep your devices running, with a friendly face designed to inject some fun into the gloomy world of charging.
The cutesy robot design is fairly minimal, so much so that you’ll likely only notice it upon closer inspection; there’s no feet or handle as there is with other products in the Uno range.
It’s relatively compact for a 10,000mAh power bank, although it’s still quite thick and the screen bulges out slightly, as does the power button on the side; the Uno isn’t a perfectly planed rectangle like some of the best power banks, such as the Ugreen 10,000mAh Magnetic Wireless Power Bank or the Anker 621 Magnetic Battery (MagGo).
The overall build quality is good, although it feels a little flimsy in places, with presses able to warp the plastic chassis, so this isn’t a power bank I would feel comfortable taking on more rugged excursions. The screen is nice and thick, though, and seems quite resistant to scratches (at least minor ones). However, the materials used are light, making the Uno easy to carry around with all day without issue.
The faces on the display aren’t just for show; they’re also indicators for the charging status. A smiling face indicates the Uno is currently charging your device, while two love hearts signal that charging is complete. There’s also a sad face to notify you when the bank’s battery is low.
It’s a shame, though, that the charging faces only display intermittently rather than continuously, meaning that sometimes you’ll have to press the power button to see what the status is. The battery percentage of the Uno also isn’t displayed unless the power button is pressed, which would’ve been another useful addition, and one that some Anker power banks feature, for instance.
The faces do change depending on how much battery is left in the Uno, but they’re too subtle to be easily read, and there’s only a few increments available: one for less than 20%, one for 21-79%, and another for 80-99%.
What is very useful, though, is the hardwired USB-C cable, which folds away neatly into its own recess on the back. It’s flat and appears quite durable, although it’s quite short, so only useful if your device or charger is close by.
When it comes to charging performance, the Uno has a 30W power output and supports two-way fast charging (three-way charging is also possible, but without the added speed boost). During my tests, it managed to charge my Google Pixel 7a from 50% to 100% in just over an hour via the USB-C port, depleting the bank’s battery from 100% to 77% in the process, so you should be able to get about four charges out of it. Charging the bank itself from 25% to full via the USB-C port took about 90 minutes, which is an impressive performance.
There’s also a trickle charging feature, designed to protect smaller devices, such as earphones and smartwatches, by providing a low-level, continuous current. It can be activated simply by holding the power button for three seconds.
As large capacity, multi-port power banks go, the Uno offers good value for money, especially considering its 30W power, which is on the higher-end of the spectrum for a compact power bank.
