Not talking about the band.

I have seen powerbanks with a low wattage 110V output come down in size to make bringing one along on my trips a feasible option.

Does anyone use one?
Can you share which one and your experience with them as well as the feature that you wish you have paid extra for?

These are the ones that I found on Amazon that I am considering:
