Customer Ratings & Reviews

At a 4 day music festival in the middle of the woods, and not wanting to miss any of the excitement of the festivals or any of the artists I planned to see, I was able to charge my phone and the phone case/battery pack without having to stand around waiting for a charging station to open up.

I love this back up power device. I simply charge it the night before and take with me through course of my day. The unit actually fully charges itself in a few hours. It quick charges your cell phone. I can get two full charges of my phone before having to recharge the unit. It will take longer, of course, if you are using your phone while you are charging it, it then basically maintains your current charge position pending the amount of usage while you are charging.I personally prefer to leave phone alone while charging and allow for a quick charge. I've used it on my iPhone 5 and my Alcatel Onetouch Flint Android phone. Excellent value for the price.

I wish I bought a lot more of these when they were $2.50. The batteries work great, only issue is that they are bulky for the battery capacity, but not an issue if you just carry in your bag. Wouldn’t want to hold this on my pocket though. Too big for that.

Gives my phone a full charge! Love it and that it’s compact

This charger was a great value-- way cheaper than other models. We used it for traveling overseas and it was a great peace of mind to know we could charge our iPhones and other devices so we didn't need to worry about running out of juice. We only needed it a couple of times, but it works great!

I love my mobile battery. I recently traveled to Europe and having a portable battery on hand is just great! If my phone battery dies, I can just plug it in to the Insignia and I'm good to go. Whether I'm in the airport or sightseeing the streets, I can be ensured that my phone is always charged.

The battery lasts for multiple charges and also charges very quickly.

I can charge my phone almost three times from this unit. It takes awhile to charge 3 to 4 hours, but it works great. For the price this little blue unit will get you through the day. It also has a neat cable stowage slot on the side.

Keeps my old Moto Razr going all day. It's a good value for the price.

Quick to charge!! I would recommend as a backup and very lightweight.

1 1/2 charge for my Samsung S6 & charges fast. Great for the price.

I bought this for my teenaged son who got swept up in the Pokemon Go craze. He and his friends would be out for hours, and the game apparently sucks your phone battery's juice a lot quicker than other apps. Anyway, he appreciated the thought, but the unit is a bit bulky to carry in his basketball shorts without weighing them down on one side. He now carries it in a drawstring pack (with water, sunscreen and other Pokemon hunting essentials like trail mix) and it's not so bad. It does a good job charging up his fading phone so he can get back to business. Price was definitely right.

Great battery, no complaints. Perfect size to be carried in pocket.

My kids and I love this portable charger it has saved us a ton of times now. We've taken it on a road trip and to the beach and so on and it works fantastic. If I had one complaint it would be how long it takes to recharge it but if you plug it up before bed it's totally done before morning so it's really not that big of a deal unless you forget to plug it up.

My daughter and I purchased several of these for San DIego Comic Con and they saved us from having to hunt down outlets and becoming one of the dreaded "Wall Huggers." We charged them up at night and used them exclusively during ComicCon and they worked beautifully.

For the price that I paid this charger does a great job. It's size is perfect for slipping in your back pocket and the right angle power cord is phenomenal.

I am very glad that I bought this during deal of the day. Never would have thought this $5 gadget would be so beneficial. It's saved me from draining my battery (phone, mp3, computer) several times and charges quickly!

This little gadget comes in hand when you need emergency power. Most of us have several charges, however, when traveling instances arise where being to be tied to a charger is not feasible. This works great and charges while streaming exceeding the battery level!

Bought this for a long road trip. It charges quickly, and I can charge my phone fully TWICE before needing to charge this again. It's everything I was looking for. Works exceptionally well for such a great price, too!

I love thi charger. It's average size, not so heavy and reliable power to fill my 3000mah phone more than once. Love the design and size and priced. Thanks to best buy for the amazing product with excellent deal price.
