    What a great power bank. I got it on sale for half the regular price. Easy to use. Can charge up to 3 de ices at a time. You have the Qualcomm fast charging option which charges fast. USB c option and 10 watt fast charging which also charges fast. Can last a long time depending on what your charging and how many device. If I'm just using it for my phone it can last over a week charging it every day. If you can find this one on sale I say get it. Still worth it at regular price but I would wait for a sale.

    Strong build design. Decently quick to charge on Android. Got on sale at good price. Only thing that really kept this from being perfect 5 was the advertisement on the front stating it comes precharged. I was on an airplane the first time I used it the day after purchase and it began with less than half of a charge left right out the box. I do understand that these do lose charge over time but I think it would have been better not to list "pre-charged" on the front of the packaging

    I was looking for a lighter portable charger that would charge more than once and was easy to pack whether it was in my luggage or purse. This charger was recommended by a salesman in Best Buy who owned one, and he was right, it is a great charger and WAY lighter than the one I previously purchased!

    Pretty good. You'll need an ac adaptor to charge it or usb- ready outlet but that's not a big deal.

    I looked at all different types and the Energizer had the most I/O. I purchased the 20,000 mAp. They also have a 10,000 mAp. I fully charged it...put it i a drawer for over one year...came back and it was still a full charge....thats impressive!!! Very clean design and high quality.

    What a great little charger. It charged my iPhone 11 from 6% to fully charged in less than 10 minutes and still had enough left (3 lights) to charge again at least 2 times if not 3. I only gave it 4/5 stars because it is very heavy. I did read reviews before I purchased it, so I knew what I was getting, but I would rather have a fast charger and deal with the weight. Note: I purchased the the 10kmAh

    In all fairness my critiques are harsh simply because I don't believe in 100% satisfaction. That being said this product is very good. Heavy but, useful. I frequently get stuck on planes, wear batteries down on multiple devices, kids "borrowing" chargers whatever the reason this portable charger has been handy in a pinch. Allows me a little confidence in my travels. Works on anything and has helped children's with traveling devices.
