We pre-power comes portability in this product. When your phone need to pick me up but you just can't stopThe Dynex portable charger is great for on the go because it's small and meets the specs of most iPhone and android products I use is an average of once a week and I'm glad Best Buy told me about it

Bought for Pokemon Go, not bad for the price. I wasn't expecting a full charge, but it provided me with enough charge till i can get to an actual wall outlet. It does come with mini hdmi like android users are using. Sorry iphone users, there is a USB input in which you can plug your lighting cable though

Inexpensive charger that holds a charge for about a month. These are great to have one in the car and backpack. I like the fact they come in different colors so we can identify who's charger is who's.

this charger has saved my phone battery so many times but the main reason why i purchased it is because i have a camera that also uses up lots of battery if im filming or vlogging for a video on my youtube channel therefore i need a backup charger and this works well it charges up fast and good for 2-3 uses

The battery itself works very well for an iPhone 6 or 7. Recharging time is also fairly short. You don't get an amazingly large charge out of this, but, it can definitely come in handy in a pinch.

I got this mainly for the cord, my old one broke for my big back up power bank, but this little one proved to be useful as well. Only good for one charge, but helped since we had multiple devices that needed a boost while we were out taking photos while on vacation, since we all forgot to bring cameras.

This when fully charged only gives my iphone about 32% charge so it’s not useful at all. I bought an Anker brand for $35 that works much better.

This charger works very well! Charges fast and seems to last for quite awhile. I plug it into my laptop when I get to work, then drop it in my purse and I'm on my way - I always have it with me when my I forget to charge my phone (which is often!). It has saved my many times in the short time I've had it!

Very reasonably priced for very decent performance, you can't go wrong having the ability and option of charging a device wherever you may be. It gets my phone to about 40 percent from totally dead.

This is a great product for the price. I have a galaxy s7 and it charged mine from 5% to 90% before it ran out of juice. Its definitely a great thing to have as a back up in case of emergencies.

You can find this one in any best buy store and sometimes on sale. I don't spent much money on external batteries anymore and I this one can give you waht you need for a weekend travel for example

I keep it for an emergency in my car. Check the charge once a week.

Great way to charge your smartphone or iPod Touch on the go. My little sister uses this to charge her iPod Touch 5th generation when out and about. Using the Apple made lightning cable is better than the one is great as its long enough to have the charger in your pocket or bag while using the device.

I bought it on sale and bought multiple for my family however this only charges one device and does not even finish charging it fully before it dies. I wouldn’t recommend.

This is good EMERGENCY power, not to be depended upon on a regular basis. This unit (when fully charged) only brought my iPad 1 back to about 30% power. I have not tried it on my iPhone 5c yet.

I bought two and gave one to a friend. Both work well for what they are. Give you more time on your phone when you are not close to a power supply. I use it to extend the time on my bike light.

i like this charger because it is compact and handy. the downfall is that it doesn't hold a lot of juice. If i use it to charge my iPhone 6 it will only charge me to about 70 percent or so.

Works great on Android phones, charges faster than the wall charger and fills a battery completely. Apple phones charge slower and get about 3/4 of a charge from these. Overall good purchase.

This little power bank works well for when you're on the go and need to charge your phone. It will fully charge my phone from being dead and still have some life in it to charge something else.

Although it isn't sufficient to give a complete charge on the phone the device is good for unexpected emergencies when you don't have time or when you can't charge your cell phone adequately.
