    Great Portable Charger!

    This was super easy to use and fit great in my backpack! I brought it with to use at Disney World to keep my Samsung Galaxy S23 Ultra charged up during the day since cellular data signal is weak there and the phone spends a lot of time trying to reconnect. The only reason I did not give it five stars is because I had it fully charged and my phone was down to about 15% and it could not charge my phone up to 100% before running out of juice. It was great in a bind though to recharge up to about 85%! Overall I would definitely recommend!

    Small power bank with a BIG punch

    Great mini power bank to give you that extra boost. It's not intended for multiple recharges. For that you would need to move up to a bigger power bank. I used it at Disney when my Google Pixel 7 Pro was at 15% and got it back to 90% in about 1 hour. Its small so you can keep it in your pocket while charging or use the phone as well. When not in use you could still keep it in your pocket or if in a bag it takes up minimal space with no cord to worry about. At the price point and what my intended use was, its been a great buy so far.

    I bought this when I was going in vacation and it worked really well. I had to use when my smartphone battery was low and I wasn’t near a plug. It charged it quickly. This battery also holds the charge for at least a week before having to be recharged. I only know a week because that’s the longest time I waited.

    I love this because I carry it in my purse and if my phone needs a charge, it just plugs into the bottom and there’s no cords and no big bulky charging brick to carry around. It doesn’t really get in the way of me using my phone.

    Excellent lightweight power bank for everyday use. It charges fast and its 5000 mAh is enough to completely charge my cell phone. It is not exactly a bargain at full price but if you need a power bank on a regular basis this is a great option.

    The device itself charges quickly, and I love how compact it is. It’s a really slow charge though. It takes 40-50 hours to get the phone to 100%. It only will charge 1 phone before you have to charge the device. It was handy at Disney World. Just wish it would charge a little quicker.

    Works well and great design. I really like that it does not require an additional cord for charging your phone (you do need to use a cord to charge the devise itself.) The USB-C plug folds, so the powerbank more easily fits into pockets.

    For the price it works out as expected and charges pretty well. I use it mainly for work as I also go to school and don't have much time in between to fully charge my phone. It does take a good bit to charge up the battery itself until it's at 100%, so definitely something to keep charging every night.
