Customer Ratings & Reviews

Great power backup. Compact and stylish and affordable.

This portable charger is perfect. Fits in my shirt pocket and charges my phone a couple of times before I need to charge it. I would definitely recommend this charger if you're in the market for one.

Convenient, colorful and compact backup power for portable devices. This device has been very helpful in keeping my older model cell phone working through long days at work or away from an outlet.

I found this device was able to charge my phone about 1 1/2 times before running out of juice. Definitely glad i bought it. Having it provides peace of mind and can work on several gadgets.

Bought for son. Light, easy to carry. Works well..

It is minimal and it feel nice in the hand. The only problem I have with this charger is that it doesn't have any buttons to turn on/off you just have to plug/unplug the cable to get it to turn on. It wasn't too expensive so one can't complain, however there are other options with buttons for the price range.

My phone is always running out of battery throughout the day. This is a nice, inexpensive, convenient way to recharge your devices throughout the day when an outlet is unavailable. Some level of foresight is necessary since you will need to, in essence, charge both your phone and this device overnight.

We have kids who seem to drain the juice out of every device we have. This battery is a lifesaver on our road trips. It works great, and is easy to use. Don't leave home without it!

I love it. I use it all the time to charge my iPhone from the 20% to 100% and still has power to charge other items.

I purchased three of these and use two for hiking and gave one to my wife. They provide about an 80% charge for my Samsung Galaxy. Perfect for recharging the phone while hiking in the backcountry and running my GPs tracker app all day long. Makes me feel secure that my phone will always be charged.

I got this product for my mom since she replaced her old Nokia with an iPhone 4s. Of course battery life differs drastically between those models. As a result the phone would run out of juice most of the time. Pros: -Compact in size. -Sturdy aluminum body. (Always a good thing inside a purse) -Bright color. (Easier to locate in a purse) -Charges in less than 2 hours using a USB wall charger. -Auto cut off feature if not in use.

Charges device quickly but gets hot when charging. Cord that comes with this portable battery only connects to the battery to charge it so that's another cord to carry around. Somewhat bulkier than I would have liked. But the price was right.

I loved it so much I brought a second one as a gift for someone else. It's bright colors have caught the attention of others to inquire what it was, and how does one operate It, and is it beneficial. My answer was yes. Not only does it charge a dead phone on the go, it doesn't require a socket to use.

This is a nice little USB backup battery / charger to have on hand. It is very handy, charges up quickly and I carry mine everywhere in my backpack... Go get one from Best Buy!

Cheap external battery, Perfect for days when you're on the go all day. Have lent to my brother who has been able to charge his Samsung smartphone fully off of this product.

My wife bought this and another one for when we're traveling, out and about, shopping, at the ball park...you name it. These come in handy in a pinch when you forget (or don't) have a car charger, or when a car charger isn't available. Charged up my new smart phone that had almost drained.

This little guy is the best!!! I always takes me out of an emergency. With my activity on my phone I always need backup power, portable fits in my jeans pocket. Must have.

I bought two of these batteries on sale (50% off) and had reasonable expectations of them. I bought these devices for a 10 day hiking trip and will see how the operate in the backcountry in August. However, I have recently used one battery to fully charge an iPhone 4 and 50% of an iPhone 6.

I really liked my battery charger. It has helped me when I didn't have access to a wall unit and my phone was going dead. I will recommend this product to others.

Bought the Dynex Lithuim-Ion battery for travel and for the car, after being charged worked quickly and as described, would rate 5 stars however unknown how long it will last. If durable would be a good purchase for anyone on the go who wants to charge cell phones quickly!!
