Power banks have been hot sellers during this year’s Prime Day sale, with two 10,000 mAh models jostling for top position on the Amazon bestsellers list. The showdown is between the INIU B6 and the Veektomx Mini (VT103), with both varying their discounts as they try to stay on top.
So which should you buy? I put both to the test and, as you can see in my best power banks roundup, the INIU B6 is the winner, passing with flying colours in my tests. Most importantly, it has the actual 10,000 mAh rating, and can output 85% of that after normal efficiency losses – an excellent result. For long-term testing, I also have an INIU B6 that has been in use for over a year and it hasn’t lost any capacity at all.
In the same tests, the Veektomx Mini outputted just 75% of the rated capacity. I also have a lightly used year-old Veektomx Mini, and it has degraded all the way down to 56% of the rated capacity. Sure, the Veektomx is slightly cheaper and slightly smaller, but it uses an under-specced battery that just can’t keep up.
So there you have it – the INIU B6 is the best affordable power bank you can currently buy. But maybe you are after a different capacity or type of power bank. To help out, I’ve included my top picks from this year’s Amazon Prime Day deals below.
