Customer Ratings & Reviews

Its a nice slim design compared to the 20k or 30k mah battery packs. It fits perfectly in my small bag that I carry with me daily, perfect fit for the zipper compartment. It has a pretty decent amount of power too, i can get three to four good charges out of it before it needs to be recharged. Its fairly light weight compared to the larger models as well, i found that when i carried the larger models in my bag it would weigh it down and stress my shoulder. Overall I very much like this model. Good job!

This Energizer Universal Portable Battery Charger/Power Bank is excellent to do a fast charge on my Android mobile phone. The cable it comes with both charges the Charger and when switching connections so it will charge my phone, it is easy and so convenient. I don't even have to take the case off my mobile phone! This was a great buy at Best Buy!!

Reliable, external battery, pack with visual battery power status, which is convenient. Larger in size and heavier in weight than my battery size comparable Anker though.

Great product, I’ve repurchased these for gifts multiple times. I own one myself and it holds a good charge and has actually lasted compared to others I’ve bought in the past at similar price points or more. Easy to use and can charge two devices at once.

I buy a lot of these. I was apprehensive about the digital display, it just seemed like more potential problems. I consider this my most functionally sound mobile battery/power bank at the moment. It holds a true charge and I like the option of either C or micro for charging it back up, depending on what I have on hand between my other electronics. Well-known brand and solid performance... Does not disappoint me... Also nice to have the option to juice up my phone and earbuds at the same time if need be on the go. I wrap a rubber band around it to keep a charger cord, and it fits just right in my back pocket.

perfect for travel and capacity readout is a plus and more accurate than bars of lights. Classy pattern and thinner size than the 20,000mAh makes this my go to product for quick trips.

Perfect battery pack! Great size—not too big or small, not too heavy or light. Love the display for knowing how much it has charged. Time will tell how many charges it holds up to but so far very happy.

This was small enough to bring anywhere and powerful enough for multiple charges of phones. I also bought another for my heated vest and it lasted all day.

Easy to use, but a little heavy. Had to get the correct accessories ( plugs and wires) for it I can get several phone charges Easy to read the power left.

These battery pack is excellent! Took it to Disneyland recently and as able to maintain my phone battery and two teenagers phones through out the trip. The slim design is perfect and fit easily into a compact bag.

A great portable charger that isn’t hard on the budget and works with multiple devices. I use this if I’m going away for a long period of time to get me through the day and more on all my devices.

Tons of spare power in this thing. I'm able to charge my iPhone 12 Pro Max 4 times fully and part of a 5th time before I have to put it on the recharger. Can be recharged with MicroUSB or USB C cables (I usually use USB C.) Only word of caution would be that if it's low you probably want to charge it overnight if you want to get it back to full power, but beyond that, this is a workhorse! Oh, and it's also bulkier and heavier than chargers with lower mAh. That's the trade-off. Still, it fits in my pocket. (I just have to make sure I'm wearing a belt.)

My favorite portable charger! Has been around the world with me. No signs of battery degradation. Compact and fast to charge!

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 power backup. For a great price. Easy to use and quick charge time.

Good backup power for my electronics. Small and easy to use . Back up my phone to a full charge fast and about 3 times on one charge .

Great in size, the battery life is excellent, and the display is correct with the battery life left.

I enjoy using this product. This portable charger charges my phone fast. I also use it for my laptop, which works well since this Energizer charger has a C-type charging port on the side of the device. I recommend it, as I have used this charger several times with just one charge.

It is amazing! I use this device to charge my phone on the go, to power my gaming chair’s back massager, and just for all around portable use. I have zero complaints, it works amazing, and I would def recommend to everyone needing a portable charger in their life. Not only does it charge my phone to full completion, it doesn’t loose battery fast when staying idle, and the LED on the top of the device keeps you up to date on how much juice it has left!

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!
