The Iniu B41 is one of the thinnest power banks I’ve used, but it won’t be powerful enough for everyone
Iniu B41 power bank: review
The Iniu B41 is a basic power bank with limited features, but a form factor that’s sure to please those who like to travel as light as possible. The power and battery indicator LED is in the shape of a paw – a design choice that’s not explained, but one I’m happy to go along with; if nothing else, it helps to liven up the monotony of the black colorway. Fortunately, the B41 caters to those who like a little more vibrancy, as it also comes in blue, orange, and red variants.
The matt rubberized finish does help to elevate its appearance, and the power button is integrated and seamless with the material, which adds to its sleekness. It feels premium too, although it’s maybe not quite on a par with some rivals. The overall build quality of the B41, though, is quite good. The joins are tight and secure, and there’s barely any flex to any of the panels.
It’s also very thin and light for a 10,000mAh battery, even when compared to the best power banks. This makes it one of the most pocket-friendly power banks I’ve ever used, so those who are constantly on the go will certainly welcome this aspect. Iniu even claims it’s the market’s thinnest 10K power bank.
As for port selection, the B41 features one USB-C port and two USB-A ports, a generous selection considering just how thin it is. Another nice touch is the inbuilt flashlight, which is quite bright considering its small size. It can be easily toggled with two quick presses of the power button.
It took about 90 minutes to charge my Google Pixel 7a from half to full capacity, which is a decent performance. Doing so depleted the battery by only one bar, which means you should be able to get a couple of full charges out of it. However, charging the B41 itself took about three hours from two to four bars, which isn’t a particularly impressive performance.
What’s more, with only 15W of power, this isn’t a bank for charging your larger devices, such as laptops. At a stretch it can charge some tablets, such as the iPad Mini, but Iniu states it will only manage 1.6 charges for this device. At least multiport charging is possible, though.
For about $20, the B41 is also good value, undercutting many of its rivals. However, Iniu also has its B61 power bank, which isn’t much more, yet offers 22.5W of power instead of 15W, as well as a screen displaying the battery readout. But while it’s thin, it’s not as thin as the B41. The B61 might be the better pick therefore, unless thinness is a top priority for you, in which case the B41 is preferable.
