Customer Ratings & Reviews

Het is small portable charger that fits easy in my pocket and charges my iphone 3 times after a 24hrs charge... For the low price, I have a very good charger for my trips.

I purchased this charger for my daughter to take with her on a class field trip to Washington, DC on April. It worked very well and to our expectations. It charged the phone quickly and efficiently. I will purchase one for myself as well.

I love this charger. It keeps charge for months when not in use. It will completely charge a dead phone and it's a fast charger. Not small

We bought this for a balloon photo shoot at 100,000 feet, we wanted power for photos and radio tel.. m At @ 35,000 ft, and -45 f, power was limited, but the insulated unit was fine. At 95,000 feet, the exposed unit burst and appeared to vaporize. The insulated unit was fine and sufficiently powered the cell phones for photos and tracking. I suppose the unit does not tolerate anything below -70 c. Unit survived free fall from 105,000 feet wrapped in 2 inches of spray foam.

Great battery. Charges my IPhone 8 several time. Good price. I bought two.

This was by far my best purchase hands down. #GetLikeMe

My two favorite things, red which is forbidden. Small... can get into places real fast and easy

I go on several trips with friends, and don't always have access to cars with USB inputs. Cigarette lighter adapters are always huge and get in the way. So if I want to read my Kindle in the car, it's only a matter of time before the battery dies, and this solves that problem! It's pocket-sized, each charge lasts a long time, and it's very easy to use. Just plug it in to the wall or PC and charge it! It has a micro USB input/output, and a regular USB port, with 4 lights to show how much juice is left. My only complaint is that the USB cable it comes with is only a few inches long...it makes the NES Classic controller cables look a mile long! I did notice that you can plug the USB output into the micro USB input, and it will show that it's charging itself...It even lights up! I didn't want to see what happens if I left it that way, but it's interesting nonetheless. All in all, this is exactly what you need if your device needs a pick me up on the go!

I was pleasantly surprised at how fast it charged up and I could get a couple of charges onto to my iPhone not super fast but, fast enough. all for under 20 bucks a good value....Charger fits in pocket not too bulky....

I bought two of these chargers for my kids whose phone batteries always seem to be on the verge of dying. They’re compact and charge quickly. They’re also pretty durable. After a few months they still hold a charge and work well. Overall very good quality for the price.

Great little charger at a great price! Hubby travels a lot and has a long commute and is never without it. Easily recharges his phone back up to full from empty with plenty of power to spare. Nice size, very portable

No question, this is the best back up battery out there. The Best Buy brand has been used by me & other family members for a few years now and I continue to buy them in varied capacities for myself & as gifts because they hold a charge longer than any other I've tried previously, small enough to take with you & gives my phone & tablet the ability to work longer when I'm out all day or during power outages when my device runs low. This leaves me portable even around the house verses tethered to a wall. It's a quality product, well priced & a great value just the extra plus.

This portable back up battery for any device that charges via USB is not only a great price but the best of its kind. It holds a charge longer than any other brand I've tried in the past. It's portable for use when out running errands, out all day or during any power outages when a cellphone or tablet is low battery but still needed. This is not my 1st experience with the Best Buy brand of these. I've been extremely pleased with their quality & decided to buy a few larger capacity versions for myself & my daughter. I'd surely recommend this to anyone looking for that extra battery back up. It's given me the freedom to use my devices without being tethered to a wall charger a lot.

This battery works great for charging phones. It's fast and lightweight, easy to read. Works with my Iphone and kid's Android phone and tablet. However, as a side note, we tried to charge his wireless earbuds and it wouldn't stay on to charge them.. Not sure if it's an energy output issue or if it's just not compatible for devices other than phones and tablets. I tried 3 different power cords including the one it came with. No luck.. Regardless, I would still recommend this for charging your phone on the go!

For the price I would recommend. It does not charge as fast as the charger the phone comes with, but that is to be expected. Good for 1 phone charge. I bought it because it is light weight and portable. I have a more expensive charging block that can charge a phone 5-7 times, but it is larger and heavy. I would recommend this for anyone looking for a single charge, easily portable, backup battery.

I got this as a special offer at a really great price. I already had a portable battery charger, but purchased this for travel. I'd rather not lose my more expensive and larger fast-charge Samsung battery. But, this works and looks great. Absolutely no problems and still holds a charge. Would be great as a backup to the backup or for your children.

Small, powerful, requires Samsung 8 or higher adapter for charging but is great in a pinch and holds 2 full charges.

I carry this in my bag with me in case I need an extra charge. I can carry it well over a month and still have plenty of battery to charge my phone and devices. It would b great if u could store the cord inside it though. Right now I have a rubber band around it holding the cord around it so I don’t lose I think. For the price, it’s great.

Bought this to use on a Universal Studios Florida trip. I was told that there were no charging stations in the park and very limited outlet access. Used to re-charged iPhone SE while eating lunch and had enough power to charge it two times. Fits easy in backpack or fanny pack. Great purchase for the price.

I have purchased two of these now. They work extremely well and I couldn't be happier with my purchases. I love the light indicator that says the charge level and it holds its charge for what I feel is a long time. It charges my phone well. Portable, easy to carry in a pocket. I definitely recommend this product!!
