Customer Ratings & Reviews

THIS IS GREAT! This battery is a high quality sturdy product that’s the same size as a cell phone. I followed the rules - allowing full charge before using it. Im impressed bc it did charge to 100% quickly and the battery lasts a long time! I often carry this w/ me when I go to a concert so my phone won’t die at “the most I’mperfect time”! I take it on hikes/outings too. Mostly it is in my home - charged and ready for any unfortunate electrical outages. I like to have a battery source for back up. I recommend this.

Great unit. Almost 4 full charges once the unit is at 100%. Doesn’t get hot and easy to use.

A really good charger. Easy to use, quick to charge, and gives a good amount of charge.

I love this!! I bought it to use on a trip while flying! It worked so well!! It quickly charged my phone better than a regular charger. It was easy to use! I was also able to use it with my iPad as well!

Nice compact power bank with a good amount of charge. Worth getting this one rather than a cheaper one so you can run longer.

Works fast, easy to pack and works with lots of devices.

Very easy to charge and transport. Battery percentage indicator makes a big difference. Holds a lot of juice!

We bought these for a 7-day cruise to Alaska with multiple excursions where we didn't have access to plug-ins. It's small, light, and compact, so it was easy to pack in a bag. We were able to re-charge our phones multiple times on a single charge of the battery pack. We always forget to recharge these, so it was great that the battery has a large capacity. I definitely recommend it!

Good unit, Charges my phone quickly. I like the digital display. My only negative is it is heavy.

* Keep this in mind - this is a lithium polymer battery bank * Purchased 3/14/23 went to Japan a week later, fully charged before we left, stayed 9 days. Charged my phone 3 times and my tablet once and it went to zero. My tablet and phone were about 75% when I charged them. Last item charged was my cellphone at 74% and the power bank was at 56%. Power bank went to zero and my cell was only up to 87%. Then it took more than 6 hours to recharge the power bank. At 14.74 ounces not sure if you consider this light. Came home to Hawaii, charged power bank to 100% and charged phone 3 times and tablet once. Each device was at 75-80 percent. After all were charged the power bank had only dropped to 75%. High and low temperature in Japan 57/50 (F) High and low temperature in Hawaii 81/72 (F) Generally speaking, this power bank will serve it's purpose in cooler (not freezing) weather though it will need to be charged more often. In warmer weather your devices and the power bank should last longer before charging.

I have a Samsung s23 ultra and drive for uber eats which sticks my battery. This actually charged my phone instead of holding the battery at the same level. 4 stars because included cord could have been better and its not super cheap

This is a very good upgrade for the times when my electricity goes off and I need to charge my electronics phone, laptop..etc.. I had a smaller one and thought I would buy this as a back -up. Works great. There is a display to tell you how much power is left on this power bank. It seems to power my phone up swiftly. I would buy again.

I purchased two of the Energizer 20,000mAh models just in case we have another power outage. I charged them both to 100% then tested one of them to find out how many times I can charge an IPhone 12. I connected my phone each time when the phone battery was between 31% and 42%. I found that each time I charged the phone the battery bank dropped 10% which translates to approximatey 8 to 9 charges. It does take long to recharge the Energizer battery bank, but if you plan ahead its not an issue at all. Although I only had them 10 days they've held a 100% charge to date. I'm very happy with my purchase from Best Buy!

Great power bank. Lasts a long time, charges quickly, and of course the LED display is awesome and useful.

Love this portable charger i got 2 for 40 when it was on sale very good deal and battery last for ever best purchase

Charges my iphone fairly quickly. Can get about 2 uses sometimes three depending on what my percentage was at. Can even get my ipad charged to full with it. So i am satisfied with this portable charger. One of the best ones ive had for the price.

The best thing about this charger is the display! It's nice to know how much charge I have left, and this is worth its price. If you're willing to spend a little more, the higher capacity charger will last you longer. This one will last me throughout the day when I'm out, but I have to charge it again when I get back. I may purchase the higher capacity charger in the future.

This unit will charge for hours. Great LED percentage readout. Charges quickly to use again.

For the money, this power bank charger is totally worthy of a 5/5 rating. I purchased one for myself as a back up for all the air travel I do and have never been disappointed with its performance. I just purchased a second one for my son for an upcoming trip which included a couple of days of camping and was so relieved to have it.

Easy enough to charge and set up. Bought it for my son so I’m waiting to see what he says about it. Energizer has been making batteries for a while so I’m assuming they made a good one here. It does have some weight to it so some people will not want to carry it in their backpack pack or purse.
