The perfect charger to bring with you for emergencies

I like the portability of the Tzumi. It takes a while to fully charge but it charges my phone pretty quickly which I really like and you can take it anywhere! You don't need to be close to a plug,

Very pleased with how rapidly my phone was charged.

Easy to carry form factor, charged up quickly. Was able to recharge iPhone 6 from 50% charge to 100% at least 4x. Indicator bars are handy to judge remaining juice.

I keep this in my computer bag and have used it for at least 4 diffent devices that have batteries and need charging. This is a must I never have to stop somewhere to charge any of my devices...

THis charger charges itself up quickly via a USB cable and holds its charge for weeks, when not in use. When I have used during travel, it quickly charged my phone and my tablet.

I use it all the time. It doesnt take long to charge, and has enough to recharge my phone and headphones a few times before needing a recharge. Also doesnt take up a lot of space in a bookbag

Great charger, especially for the price. Am able to fully charge my Note 4 while simultaneously and continuously using the phone. Like the LED lights indicating the amount of charge on the charger.

I bought this for $14 and am pleased with the ability to charge on the go. It is small enough to fit in a pocket and can fill up my phone at least once, so long as the device is charged recently.

I bought this to replace another portable charger that had stopped working. The size is great for carrying in my purse and it charges much faster than my last one!

The portable charger is pretty decent. The addition of the flash light comes in handy. Takes a few hours to charge and can charge up to 2 phones off just one charge.

I purchased this charger before i went on a trip. It performed as expected. I was able to charge my phone at least once over and it charged it quickly. Size is a plus.

The power bank charges multiple devices completely. It says it will charge 2 smartphones but I have charged 2 and about half of another. It doesn't get hot while changing like others I've used.

A really compact , good looking charger . Recharges fast and can get my phone up and running in a half hour . It has a green light to show how much powers left .

This product works great! has 2.1 amp charge so it is considered a rapid charger, much faster than 1 amp charging. Great for an iphone 6, 6s or 7. Very useful charging pack for travels.

This item was a must have for me since I spend so much time traveling from state to state, with so many electronic devices to keep charged up while on the road.

I purchased this for my wife. It was on sale at a great price. Now she is able to take pictures when we are out and about. Also, I like it because she has a charge when I need to reach her.

Does not live up to its claim of charging up a device up to two times, but works nonetheless. I typically get one charge out of it, a little less than a full charge if my phone is completely dead. It serves its purpose in keeping your phone from dying in case you can't get to a wall charger or USB outlet. Very convenient when on the go, I can charge my phone in my purse. It's not terribly big, though there are smaller power banks available. The price was very affordable.

My kids are always on their phones texting, gaming and wears the battery down. So this is a good battery back up for when they're out and about with friends.

This device is great! I get about 1% per minute with it and it will fully charge my Galaxy S5 two full times before running out. Great product! I actually have bought two of these now!
