Customer Ratings & Reviews

This device is very convenient and extends the use of a cell phone battery, our teenage daughter is happy to have it.

This was great for a day sightseeing when I didn't have access to a plug in. Discovered you must use the official charger cord (not an off brand I also purchased at Best Buy) or iPhone will not charge from this device.

This charger works great for all my devices, it is easy to use and comes in very handy when you are out for a while.

Works well with charging phone after the battery dies. You can even use your phone while it's charging. Love it.

This is a very good product and serves a vital need to those who need to charge their device when away from a plug. The charger is good for charging while travelling or in an emergency. This Dynex charger has to be one of the best and most useful items I've purchased.

This spare battery saved me a few times on my vacation when I didn't have a car or wall plug to recharge my iPhone. The only complaint I have is the manufacturer should have upped the mAH to give a few more charges.

Great product. Compact and easy to use. Charges my phone with no problem.I keep one at work and one in my car.

I purchased this for my wife as she travels often for work. On the news, we saw that their was an issue with people using public charging stations as places to hack other people's cell phones. With this, she was able to keep her phone charged all day without using the public access points. She simply charged it at her hotel and was ready for the next day. Worked great! Only wish is that it came with it's own AC charger. But we have extras so it wasn't a big deal.

Works great. charges my phone quickly. Very useful if you are travelling and often forget to charge your phone.

portable chargers definitely comes in handy when your phone is dying. compared to the other ones that were $35 and up, it was worth the 7 bucks i spent on it.

I purchased the Dynex lithium battery to increase my phone time on a recent flight, but it turned out to be a lifesaver. After driving my daughter back to college I had a flat tire on the highway returning home late at night. My smartphone battery was almost gone and I remember I still had the Dynex in my purse. It gave me the all the juice I needed to get home safely.

Husband needed something to keep him charged consistently as he is often located without an outlet. So far it is working great. We'll have to wait to see what the longevity is. But happy with it currently.

I am always forgetting to charge my devices. this is a portable, powerful charger at an excellent price!

Works good, holds its charge. Does what is supposed to do. Only concern is that it hearts up while in use.

I was checking out at best buy and i saw this on sale at the counter. Bought it and was very happy with my purchase. Works excellent. Just charge it and use it on any usb electronic and it recharges it!

This thing saves me everyday! I play pandora and games all day and my iPhone 5s battery life sucks. But It can be almost dead and this will give me an complete charge to get through the day with no worries.

Great unit and convenient for traveling. This is the second unit I purchased because we have two phones.

I was curious about these portable chargers and when I saw this one at such an affordable price I couldn't pass it up. It has charged my HTC phone well and is handy to have in case of emergency.

It's a great charger to travel with. I came in very handy . I even shared it with my boyfriend . Instead of standing are sitting on the floor in the airport. I just pull my phone in my portable charger

Purchased this charger while on vacation. I was constantly on my phone using the camera or texting, so towards the end of the night, my phone was almost dead. I am so glad I purchased this charger because I was able to carry it with me during the rest of my vacation without having to think twice about using my phone in order to save the battery life. The only downside is that it can get a little heavy in your purse after awhile.
