Customer Ratings & Reviews

Got 2 of this for myself and my sister and it is a very good product.

I bought it because it’s the energizer brand and that it was on sale helped a lot. I love to be able to take it from room to room. I needed to replace one that got lost on vacation.

This has been a great product, a bit chunky but it goes on for literal days without charging again

Don’t recommend. If you. You have to always hit the side button to turn it on or else it won’t charge your device. Now I can’t use it because it keeps power surging my phone and it won’t charge any devices. Says 100% on the battery pack but it’s useless now. Lasted barely 6 months. I’ll buy something different now

Got two for my boys as we travel a lot and their bus ride is long. Chargers are slow to charge, if completely drained it can take over 24 hours to charge up. They are also charge phones slow. Easily broken if dropped. Oldest son broke his within a few months as he uses it the most. I recently dropped the other one onto the kitchen floor and it broke in a way I can’t tape it to hold it together so it isn’t usable. Same day I dropped my old charger (different brand) from the top of the bleachers onto concrete and it is intact without damage. I’ll be replacing these with something more durable.

Charger does not keep charged and very slow to recharge and charge devices. Device is also very heavy.

Purchased when they were on sale. Slim. The size is better than most.

Great product, Excellent Price. Recommend to others.

I bought this battery because my phone's battery was becoming inconsistent, When I started using it I plugged it into USB port 1 which did not change the phone for some reason, however, I put it in USB port 2 which started charging my phone right away. I was somewhat disappointed because I was under the impression that fast charging would take 2 to 4 hours to fully charge. this battery takes about 5 to 7 hours from dead to full. However the price was only 20 dollars and it has served its purpose of making my phone last the day, so I guess I cannot complain to much.

This was not a good battery and I had to get a new one. The battery arrived being expanded/bloated which is hazardous. I assume something happened as it was shipped. It’s a good battery, just this one was bad.

Dies after charging for 30 minutes at most and doesn’t even charge my iPhone 14 Pro Max battery more than 50% before it dies

Bought two of these to have when traveling for work. The box said they could give multiple charges for smart phones. When my phone was about half dead, it killed the fully charged battery pack trying to charge my phone. It takes almost a full day to recharge and has been pretty much useless. Sadly I bought two and it's been a waste of money.

Exactly what I needed. Holds its charge very well and can last the hold day if needed. You can also charge two phones at once if you need to. Tip though, when I first took it out of the box to charge it, it got stuck on 85%. I solved it by using the power until around 50 and then charging. It's worked fine ever since.

I purchased 2 of these power banks, and have had them for several years, the full charge can charge 2 of our phones. Its a little bulky, heavy, but It has done the job, only recently, have dropped it too many times, still works, but taped up with black tape.

This works precisely as advertised. High Capacity 20,000 mAh ultimate power capacity that can charge a standard smartphone up to 6 times. Yes! 6 times. The bright LCD screen shows you how much power remains in the power bank so you always know how much power you have. The Dual Inputs are handy. You can recharge your powerbank via the USB-C input or micro-USB input. Energizer is a name you can trust. I was a little disappointed with the weight. Little heavier than expected. And, many of the other" chargers "out there" have more "whistles and bells!"

Instructions are easy to understand and charges to 100% quickly and works with all types of phones, tablets, etc. Small enough that stores almost any place.

Charges my iPad Air about 70% from full charge. Charges my phone at least twice (15 pro). The battery recharges quick enough. Overall satisfied and recommend for very portable charger that will fit anywhere your phone would

It works great! It comes out of the box with about 80% power and so I tried to charge it up to 100%, but it stopped at at 86%. After doing some research, I learned that you should use it right away to charge your phone, tablet, etc to drain it down a ways. Then, when you go to charge it up, it will go all the way to 100%. It's a real convenient portable charge to have, and a great value.

Its very pocketable and i love the lcd display letting me know how much charge it has exactly, it charged mine and my girlfriend phone fully and still had 32% left i would like the larger 30k mah one for travel but this one is perfect for daily use. The only problem ive had with it so far is ive forgotten my phone twice thinking it was my phone in my pocket bit thats me being dumb not the devices fault.

Excellent battery pack. Came pre-charged at 75%. Took about two hours to get to 100% so not lightning fast but good enough for us. Our son used it for his iPhone8's ever failing battery. Began the day with 97%, came home from the convention with 93% while using it all day to keep the phone alive to take tons of pictures. He kept it in his pants pocket and said it was very light, did not get hot and he liked the display. We will keep this in our backpack when we visit the Orlando Parks.
