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

Compared to the first generation, this one works great, it has more endurance, even though it declares the same capacity

The entire powerbank is not even enough to fully charge the mobile, so the question is whether it is better not to invest in a larger one.
