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.

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.

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.

Great little charger that gives you an extra boost to get through the day.

Ideal size. Variety of colors. Easy to use. Charges quickly and lasts long.

This is a really good gadget for keeping you topped up. Its a great colour and slim and small enough to keep in your purse or pocket. Great for days out when you're taking lots of photos with your phone and need an extra boost.

I needed a portable battery charger because my android phone loses power before the end of the day. I purchased this portable charger because it was the least expensive one I could find and I was concerned it might be a lemon -- nope -- it works great. It charges the phone, is easy to carry around in my purse, and I charge it at night along with my cell phone.

Great size and weight, mobile charger great to have when time runs out!

I ordered this for my daughter so she could have a back up charger for her phone. The price was great and was able to get it her favorite color. She has used it several times with no problem.

Fits into small bags and is very light to carry around if your battery is getting low on your phone. Easy to change cables too. All you need is a USB port to the charger and any cable will fit.

This is a decent back-up charger for immediate use. I'm able to fully charge my phone whenever the battery is completely depleted. The only issue I have is that this battery does not hold a charge for more than a couple of days so you will need to use it immediately otherwise it will lose charge.

This is really just a back-up,'just in case I need' it device, but I haven't actually had a situation come up where I needed to use it yet. I did charge it up and verified that it appears to power and increase the battery level of my mobile device I plugged it in to. It is sufficiently small and light for my purpose.

This is such a great charger. It charges very fast. It's small and looks good. Easy to carry with you and use whenever you need it. I'm gonna get a couple more.

This battery was definitely a good addition to my phone's arsenal. I usually use my phone from dusk to dawn and this battery helps me. It charges somewhat quickly and lasts a good amount of time. I would definitely recommend this to both a friend and anyone who wants to expand their phone usage.

pretty much all you can ask is for something to do what it says it will. not a long charge but not a big battery, perfect for phone or small player or camera etc and doesn't take up a ton of stuff...good for concerts, or camping or other long excursions where you won't have charge capacity.
