Juovi J2621 20000mAh 45W Power Bank review
The Juovi J2621 is a 45W power bank with a large 20,000mAh capacity and four ports for versatile, long-lasting charging performance. It’s a hefty brick for sure, but thankfully it’s not as heavy as it looks. This means it would be easy enough to carry around in a back, but not slim enough for pocketing.
Overall, its design is fairly anonymous, although the two-tone colorway adds some interest. There’s no clutter to ruin its minimalist credentials, as there’s only one button for the power, but ultimately, the J2621 won’t win any awards for style.
The build quality isn’t on a par with some of the best power banks, as there’s some flex in the chassis when pressed, and the front and back panels have prominent joins that feel sharp in the hand.
However, one very smart-looking feature is the display. It’s imperceptible when inactive, since there’s no glass screen; instead, it shines through the chassis when on. This also means there’s no delicate glass to scratch or crack, which is reassuring.
The USB-C ports provide up to 45W of power. Charging a Google Pixel 7a from half to full took just over an hour, which amounts to an average performance. Thanks to its large 20,000mAh capacity, though, the J2621’s battery only depleted by 16%, which means you should be able to get about six charges out of it.
On the other hand, the USB-A ports only reach a maximum of 30W each. Charging a Pixel 7a via this method was inevitably slower, taking closer to two hours, with the J2621 depleting by 17%.
There’s also a trickle charging mode, designed for low-current devices such as earbuds and smartwatches. It can be activated easily by pressing the power button twice, with an indicator appearing on the display.
The J2621 itself took just over an hour to charge itself from 70% to full, which isn’t bad considering its large capacity.
Ultimately, if you need a large capacity and port selection, then the J2621 is a worthy choice. It undercuts some other power banks, including those from Anker, and although it’s not as well engineered as its rivals, or as portable, it still makes for a versatile power bank.
