    This charges my phone quickly but only has enough power for one full charge. A decent value for money.

    Gets the job done. I easily get 4 or 5 fully charged batteries on my iPhone. It does take a long time to charge itself, but that was expected. Also doesn’t heat up.

    It keeps my IPhone charged at the end of the day. I usually charge my phone overnight and at the end of the day I’m running low on battery because usage is augmented every day.

    Needed a small light and easy to manage charger - this one certainly does the trick. Is more compact and charger much faster than I thought it would. Satisfied with my purchase.

    Fast charge. Size is nice because I hold it with my phone and use it while charging. I can’t speak to how long it will function, though, because it’s still new.

    Slim and portable. It is warm while it is charging. I bought it while it is on sale and for Energizer brand(battery cell is better than unknown brands). so far it works as I expected. I only need a power bank in my backpack in case my iPhone is low in battery, sometimes, for iPad. nothing fancy.

    Great little battery pack. I think it can power 72 hours worth of cellphone battery which is more than enough for long trips. It's a bit excessive because I don't think I'd ever need 72 hour backup battery - but it can charge 2 phones simultaneously and is nice for the whole family, no worrying about anything. It's even nicer to have for when we've had these power outages from recent hurricanes. It's not heavy at all, but a little lighter and smaller would be nice. Cannot fit it in my pocket, but easily fits into a small bag. I would recommend it and would buy it again.
