We all have smartphones and all sorts of different gadgets, and most of them are pretty power-hungry. Vinsic has a power bank that may help keep the lights on for a long time as it has 20000mAh cell inside. Find out more in our full review.

The Vinsic power bank comes in a simple packaging and all you are getting is the USB cable and some documentation.

Naturally, it is not that easy to produce such a big capacity external battery in a small footprint and the solution by Vinsic is a clear example. I would say it is about 3 times larger than the popular Xiaomi power bank, which has the capacity of 10400mAh.

On the other hand, one of the selling points of this device is it thinness of 12mm. On the top side we have two USB ports – one capable of 2.1A of output and another of just 1.0A of output.

On of the key features is that there is an LCD display with the integrated touch panel and it shows the the amount of power left in power bank.

As far as design, we have all-metal unibody aluminium shell, which makes this external battery look and feel premium. Also, the device is very well constructed.

The Vinsic power bank performed well during our testings as any other high quality external battery. It charges other devices quite fast but we wished both ports were capable of at least 2A of output.

CONCLUSIONS

So here it is, the Vinsic Alien 20000mAh Ultra-slim Power Bank. First of all, it has a great design, a premium all-metal shell and top-notch build quality. Also, it performed well during our testing period with different gadgets, which included smartphones, mp3 player and another power bank.

However, one of the key disadvantages is the size. We indeed appreciate that the power bank is slim but we would actually prefer it to be thicker but smaller.

Also, the addition of two USB ports is great but only one if capable of providing decent speeds of 2.0A while another is stuck at 1.0A.

Finally, although you are getting a premium packaging, the Vinsic Alien 20000mAh ultra-slim power bank is not exactly cheap as it retails just below $50. Well, it is not the most expensive external battery out there but we’ve seen some cheaper alternatives made by Chinese competitors.
