Customer Ratings & Reviews

It's inexpensive and works great. I charge my iPhone 6+ 128 gb when it gets down to about half charge and it brings it back up to 100% battery life (you need a seperate charging cable for iPhone). I than leave it in the USB port on a computer until I need to recharge. It's great to not be tethered when having to charge your phone also.

revolutionary thing. The battery on my phone can not withstand even a whole day. This battery helps me a lot to be able to feel comfortable by the end of the day and not to worry that I will run out of battery

A very good portable charger it last a long time..

Daughter loves this color! Charger unit has worked fine on all tablets, phones except for Fire HD. Light, easy to carry, can top off charge or give near full charge. Good deal for Black Friday price.

Easy to carry, quick to take or give charges. Perfect. Bright red makes it easy to find. Not too heavy or odd shaped. Bought more for my sons & my dad for power outage backup.

This charger comes semi pre charged. I was in a pickle the day I got it and needed a quick fix until I got home to my charger. In total it gave me about 30% battery before it died and needed recharging itself. When fully charged I get about 60-75% battery charge for my iPhone 6. I would like to have a full charge when I buy one of these things but for the price I paid $8 it is a good deal. I now have 2 so that I can get a full charge when I need it.

The Dynex portable battery recharger is such a great way to get that much needed recharge when on the go. It is easy to set up and gives a guick charge when needed. It is small and easy to carry in a purse. I have used it many times since purchasing it and each time it has worked great. I will definitely continue to keep it charged and ready to use.

I love this battery. It is small enough to fit in my pocket. It is inexpensive and easy to charge just plug it into a computer via usb. Great for long nights out. It doesn't come with an iphone charger wire but if you have one you can just plug it in there. It charges with the wire it comes with.

As far as spare batteries go for recharging your portable devices, this one is fairly standard. There's no bells or whistles, and it does it's job. There's little setting this apart from others on the market. It retails for $20, though I got it on sale for $10. This particular brand is owned by Best Buy, so that's probably why it was discounted to get greater sales. After doing some more research, there were better batteries for the same size and capacity, but since this was on sale I decided to get it. It does work with anything that can be recharged via USB, so far I've used it on my iPhone, iPod, and PS Vita with no issues. Be aware that it only comes with the USB cable and no wall adapter, so you will either need to charge it via your computer or have a USB wall charger, which most phones have.

This power pack is effective and convenient. If you ever been out and have a low battery on your cell phone but no access to car charger or outlet to charge up your phone then you need this product. This power pack came in handy many times so far as I was able to plug in my phone and not have my phone battery die on me. So convenient because I am not always near an outlet and allows mobility while charging unlike wall charger. A must have if you're a habitual cell phone user.

Wife bought these for when we're on the road, at baseball games, out and about. These come in handy in a pinch when your smart phone battery is draining. Compact. Portable. Lightweight. Low profile. Charges well.

Good unit for the money. My Note 4 needed a larger unit to obtain a full charge. This unit does get it back to a 1/2 charge from zero. Comes in handy when on the run. Fits in my pocket.

This product is good for getting a little extra charge into your phone while on the go until you reach an outlet. I haven't gotten a full charge out of it, but it brought my completely dead iPhone up to 83%. It's a little slow to charge (it took about an hour and a half) and you can't use your phone while charging. It comes with a micro USB cord, so if you will be charging an iPhone you have to purchase a separate lightning cable. Carrying the portable battery and cord in my purse with me isn't a hassle and it's not heavy. For the price and convenience, this is exactly what I was looking for!

Yep. It worked. Have bought others that didn t. And came with all necessary adapters for lots of devices. Reasonably priced and always throw them in kids bookbags so they can t say they didn t call and tell me where they are cause, "Dad, my phone is dead." Good for oldest who is driving so he can call if phone dead if car breaks down. What can I say, I worry.

comes in different colors and handy. Very thin piece so does not take a lot of space. It holds charge as nomally devises will do. 2200 MAmp capacity.

I purchased this while it was on sale and took with me on a trip. During the trip several people with me required it and were able to use it with no problem. It quickly charged their phones whith no issue at all. It was fast and simple to recharge. This is extremely handy when you are in need of a charge. It is small, light and easy to use.

Bought this as backup battery power for my Samsung smartphone. Easy to use. Small size comparable to similar products by other manufacturers. Full charge on external battery provides near full charge from empty on smartphone battery (when power save function is enabled on smartphone.) Appreciated being able to pick a color to suit my style.

I have several of these as I travel a lot and I love giving them as gifts. I normally get about three-four charges out of one of these. They charge fairly fast too and are much less expensive than other power banks but work just as well if not better. Would deff recommend

This was a great buy for me. The battery back up is light and easy to carry around. Works with all my devices. Lifesaver for a long car trip when the devices start running out of juice. Kids are able to continue what they are doing on the tablet.

This is a great little gadget to keep in your purse or car for those emergencies when your phone or device battery runs low and there is no immediate alternative charging method. The price was great. You do need to recharge it if you don't use it for a few days. This works great for my sons Kindle and tablet when we are somewhere without charging capabilities and his battery runs low.
