Análise do carregador portátil Xiaomi de 33W e 10.000mAh

The Xiaomi 33W 10,000mAh Power Bank is a small power bank with an integrated USB-C cable for added convenience, making it ideal for light travelers. The smart, minimalist looks are welcome too. The Ice Blue colorway I had looked classy, but there’s a Tan variant if you want something a little lighter. Both models are elegant and complement the sleek form of the Xiaomi 33W 10,000mAh Power Bank.

In keeping with its uncluttered approach, there’s no screen or interface to speak off, aside from a power check button and four discreet LED dots to indicate battery and charging status. Despite their small size, they’re pleasingly bright, which makes them easy to see at a glance or at a distance.

I also appreciated the small form factor, with its square shape taking up little room. This is all the more impressive considering its 10,000mAh capacity, as not even some of the best power banks this size have such a small footprint. However, it’s thicker than some of them, and while the Xiaomi 33W 10,000mAh Power Bank isn’t exactly heavy, it’s not the lightest either.

The plastic material body feels reasonably premium, as it’s smooth to the touch and feels solidly constructed. However, the stress relief for the integrated USB-C cable seems quite flimsy, and I wouldn’t trust it to withstand too many bends or prolonged squashing, so I’d be careful when packing it deep inside a bag. I also wouldn’t use it as a carrying handle, although in fairness, Xiaomi doesn’t mention this as a feature.

Unfortunately, the housing that keeps the jack end stowed away isn’t as secure as I would’ve liked either. It does preserve the perfectly flat contours of the bank, though, as the jack sits flush with the side panel when stowed.

In addition to the integrated cable, the Xiaomi 33W 10,000mAh Power Bank also has a USB-A port and a USB-C port. Three-way simultaneous charging is supported too, as well as two-way 30W fast charging.

Charging performance is good, as it managed to charge my Google Pixel 7a, which has a 4,385mAh battery, from empty to full in just over 90 minutes, which is a solid performance.

More impressively, the Xiaomi 33W 10,000mAh Power Bank only lost one of its four LED dots, which means you should get between 2-3 full charges of a smartphone out of it. Charging the bank itself takes somewhere between three and a half to four hours, which is reasonable for this battery size.

For the price of £19.99 (about $26 / AU$41), the Xiaomi 33W 10,000mAh Power Bank represents good value. Not many power banks with this capacity take up so little real estate, nor have an integrated cable in addition to two extra ports. The cable might not endure as much punishment as others, but for light traveling the Xiaomi 33W 10,000mAh Power Bank should make for a convenient companion.

Devo comprar o power bank Xiaomi de 33W e 10.000 mAh?

Buy it if…

Quer uma power bank compacta

Many power banks with this capacity are surprisingly small, making it easy to carry in your pocket or bag.

Precisa de várias cargas

A Power Bank Xiaomi de 33W e 10.000mAh consegue recarregar o seu smartphone várias vezes. Após uma carga completa, só perdeu um indicador de bateria, pelo que pode esperar pelo menos algumas recargas completas com ela.

Não compres se…

Estás a planear aventuras ao ar livre

A Power Bank Xiaomi de 33W e 10.000mAh é bem construída, mas o sistema de alívio de stress incorporado não é muito resistente, e a caixa do conector não é das mais seguras.

Preferes um design mais fino

Embora seja compacto em comprimento e largura, é relativamente espesso em profundidade — algo que pode ser a dimensão mais importante para alguns utilizadores.

Iniu B41

The Iniu B41 has the same capacity as the Xiaomi 33W 10,000mAh Power Bank but is slightly cheaper, although it has less power and doesn’t have an integrated cable. It does, however, include a handy flashlight. And while it’s longer than the Xiaomi 33W 10,000mAh Power Bank, it’s thinner, which might be preferable for some users. The port selection is slightly different too, with two USB-A ports and one USB-C port. Read our Iniu B41 review.
