Power banks are becoming more and more essential, with all of the new bezelless phones. Today, I will be giving you an unbiased review of the ROMOSS Polymos 20 by taking a look at all of the different aspects that this beast has to offer.
First of all, the specs. This device has a battery capacity of 20000mAh. It has a 5V and 2.1A input and a 5V and 2.1A output as well as a 5V and 1A output. The power bank is rather bulky, its dimensions are 16 x 8 x 2 cm (6.3 x 3.1 x 0.8 inches). Fully charged, the power bank weighs 482 grams (17 oz).
I was given a period of a week for this review, and I have not had to charge the device more than once. I received the power bank with 50% charge in the box and then charged it completely full. In the 6 days that I used it after this, I have not had to charge it. At the end of the week, the power bank battery display was on 1 bar and it had charged my phone around 5 times. It’s ideal for school or work if there are limited power sockets.
The power bank has consistently managed to charge my OnePlus 3 to 40% in half an hour when using the original Dash Charge cable connected to the 5V 2.1A socket. It can also charge 2 devices at the same time. I was really impressed by the time that the device charged itself in. It took it 4 hours (a night) to charge from 50 to 100%.
The outside of the power bank feels like cheap plastic and it catches a lot of dust. It also becomes dirty very easily but this is easy to clean off because of the hard plastic shell. Furthermore, the LED’s aren’t bright and are not visible in outside light, but these are both minor cons and aren’t deal breakers.
In the end, the ROMOSS Polymos 20 is a great power bank for traveling or for school. The pro’s massively outweigh the cons for me personally. To be able to charge my phone whenever I want at a fast pace is perfect for me. But if you prefer a stylish looking power bank, ROMOSS sells those too.
