Our Review/Thoughts
Nice bright screen, good build quality You will often see huge capacities on a power bank, but there is seldom a way to actually check if that is true
Comes in a blister pack with a card back (the kind that slides out - the plastic doesn't have to be cut)
It does its job perfectly well without any issues
Really helpful bit of equipment at a reasonable price does exactly what it says in its description and enables you to determine weak cables and charges
I just throw out 3 bad USB cables because of low current flow
It is compact, easy to use and reliable
