Customer Ratings & Reviews

Great for day-long outings as it holds a full extra battery charge. Charges pretty quickly. We actually own two in our family and will probably buy more for everyone else.

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.

Works great and is a real bargain for the price. Feels sturdy and looks professional too. The only thing holding back the fifth star is that the light to see it charging or complete is not so plain to see. I have to pick it up and look at it, a small task considering the bargain price.

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.

Very handy to carry with a capacity of 2400 mAh. Charges my Galaxy smartphones in 40 to 50 mins. Charges faster than the wall charger and I believe it pushes more current ( 1 to 1.5 A) compared to regular wall charger. Color LED is very helpful to know the state of portable charger.

I was making plans to fly from Houston TX to Kansas City MO during Christmas. Last time I made that trip my phone battery went almost completely dead. I had a layover in Atlanta but due to so many people already using the charging outlets at the airport I was not able to recharge my phone. So this time I decided to be prepared. I bought this battery charger & was so glad I did. I got to the Kansas City airport for the return trip to Houston & my flight was delayed. Of course, to pass the time away I played games on my phone. Then while on the plane I was able to recharge my phone with the battery charger.

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.

Have you ever been below 10% battery life and there isn't an outlet in sight? Well, I think we all have and that is where the Dynex Lithium-ion battery come in handy. It has proven to be a life saver and you will appreciate it as much as a gas can when your almost out of gas. Get one.

Provides quick charge to my Bluetooth ear piece & my phone. No need to worry about running out of a charge .... just plug in my portable battery! Wonderful product.

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!!

Got this charger on clearance for $6.00 and I love it! It's works well and is small enough to carry in my briefcase or purse without being cumbersome.

I purchased this so that I have the ability to charge my Iphone 5C when out an about, away from my car charger and with no access to outlets. It is especially great for traveling. It recharges my phone quickly and easily and seems to be a good find. I have not yet had to charge my phone for long periods with it so I cannot address how long this charger will hold a charge before needing to be plugged in and recharged itself. I have only done short recharges, but it has done well. I usually plug it in to recharge before a trip just to make sure it is well charged.

The battery works as it's supposed to . Very compact to keep in a bag and use to top off a phone or tablet while on the go. Perfect for a day trip.

You can use it with any phone, you just have to have your charger cord with a usb connector. Not heavy at all so you can put it in your pocket and forget about it. I didn't try the storage option for data but if it is as good as the power storage it will be great. :)

Small enough to throw in my purse and have in case of emergency.. One charge is plenty and I just bought one for my daughter to keep in her purse.

I am definitely pleased it is easy to use, fits well in my purse and is just the right size. I would definitely recommend this product to others !!

This is a great value! It's far better than units twice its price! It's durable and the charge lasts longer than any other charger I've used.

I use my phone a lot throughout the day and it is constantly dying on me. Thankfully I got this for Christmas and it's saved me time and time again.
