Verified purchase - review from a price comparison website
It’s a shame they don’t make power banks with a capacity that’s just right for my mobile’s battery (6,000 mAh); this one’s a bit too small, and those with a capacity of 10k or more are, in turn, unnecessarily large and heavy.
Small, lightweight
Just the right size for your pocket
