Great amount of juice for when you need it thanks.

Bought it for camping so I could have extra charge

Nice size, multiple charges of my phone and tablet

The charger works like it should but you have to carry around your iPhone charging cord to be able to charge your iPhone. The charging cord that comes with the charger is not compatible with the iPhone.

I'm using this as a back-up battery to another "Best Buy" battery that is my primary. It doesn't have as much juice as my primary, but I am able to complete my work day with this battery when the primary is drained. This product is doing what I bought it for.

Needed a battery pack for a teen who's phone is always dead. Went for twice the mA to hopefully get him two charges per cycle. The included cable seemed to be a little flakey. I think it works, but like all things with a teen, it's probably lost in his room.

It's an okay back up charger. A little bulky but works really well. I wish the green light wouldn't stay on, as it seems to drain the battery of this charger. Flashlight is good too

This a nifty portable charger that comes with an LED light. I gave it 4 stars because I feel like it doesn't do as many full charges as it said it does but I'll have to test that out again. It still does enough for 1.5 charges.

Good for the price. However would love to know how much charge is left on the portable charger so you know whether to recharge or not. But again it wasn't expensive so it works!!

Decent battery. You can't through charge (charge your device and the battery at the same time). The USB cord shorted after a week. It is less expensive than many other alternatives.

It does the job of charging my phone and definitely holds a good enough charge, but the size of it and the charging cord it comes with makes it a bulky item in the pocket.

This device broke twice while I was trying to charge it. I discovered it was my computer's usb port. Device wirks fine but the usb cord stopped working and I had to get a new cord.

It's a nice pocket charger the only bad thing is that the small cord get a bit loose at the phone charger side u have to wiggle it to work. It should not do that.

This product is alright. I got it for pokemon GO game. When playing game, it keeps phone on and slowly charges. When just charging, I can get 2 full charges out of it.

I like that it has a flashlight. charges my phone only twice instead of the 3 times advertised. the product I really wanted was not in stock so I settled for this one.

Bought for a trip overseas. If I remember correctly, it serves its purpose. Lost the charger a bit ago, so haven’t used in a while. Honestly, don’t even know where it is right now.

I wasn't too sure what to expect from a product like this which was priced extremely cheap on Best Buy; however, I can say that I am happy with this purchase and feel that I have a quality product that does as it says it does in the item description!

iPhone 7 plus is my first phone and previously, I have owned android phones. I have always used Morphie portable charger for android phones. It was very reliable. This product, Tzumi, took a long time to be charged. When plugging it to the iPhone, it was nearly used up the whole portable charges. Would I recommend this product...no, not if you own iPhone 7 plus because its battery last a very long time. But it would be useful to have a portable charger for travel or if you're away from places with plugs. Try other product instead of Tzumi.

Its a good charger, but after you leave the device plug into it will do an auto-shutdown even if the device isn't fully charged which is kind of annoying, Other than that its a good charger.

I like the charger though I have one complaint - the charger doesn't always begin charging immediately when plugged into item needing charging. I have to manipulate the cord to get it to charge.
