Best powerbank I've used yet
Sat, 12 Aug 2017 | Review by: Geoffrey
Feels rock solid and very well made. A previous powerbank that I used from a competitor didn't charge half the time. This powerbank however has none of the said issues. Charges quick for the size of the battery and was delivered ahead of schedule again by loot!! Fantastic!! Should last me a good few years from what Ive seen so far :)

Simply the best
Sun, 10 Sep 2017 | Review by: John K
I am somewhat of a power bank junky. I hate being without power, so I have bought just about every power bank out there. I was disappointed with my other Chinese power banks. I then bought the Romoss Polymos 20, and right away I knew I had received what was advertised - this is a heavy battery....and for very good reason.
I bought a resistor bank and current meters to check out my power banks. I was shocked to see that 95 % of the power banks I bought had wildly over inflated their capacities. Most 8000 mAh batteries were in fact only about 1500 mAh. This Polymos is what it is rated at...I can fully charge about 5 phones completely with it on one charge. I will now only buy Polymos 20 for my future needs

Works like a champ

Took this travelling through Europe. The dual charging feature was a godsend as well as charging the powerbank and devices at the same time. Charging is fairly quick and the powerbank does not get excessively hot.
