Great product

Awesome product. Love the added light. Little larger and heavier than I thought from picture but does exactly what it's supposed to.

As Stated

I did not perform extensive testing, but it seems to do exactly what it claims to do. I got this one at a fairly inexpensive price ($33), so I'm quite happy with my purchase.

If I carried a backpack or purse it would be awesome in one of those

I ordered this because a hurricane was coming and I wanted some backup power for devices in case power went out. Then I found out this is handy not just for emergencies but everyday use. When visiting family or in a room where outlets are scarce it doesn't matter as long as I have this to plug in my phone. If I carried a backpack or purse it would be awesome in one of those. A little too heavy for a pocket but could fit in a large pocket.

this thing is great!

I don't know how I ever lived without it. I can charge all my stuff at once without worrying about over charging. I love it.

Great Item for People that Need Power on the Go

This is a good power bank for phones and other small electronics. My son and I started playing Pokemon Go and needed something to keep the phones going on the longer walks. We can keep both of our phones plugged up for 4-5 hours charging and the battery will still be 50-75% when we get home. It will charge from 25% to full overnight but if you need a quick charge, it can be fully charged with both adapters in a few hours. The flashlight is a bit dinky, but we have used it a time or two when out. There is a good bit of heft with the battery, but it fits nicely in a back or cargo pocket.There are other, more technical reviews out there, so I will leave you to those if you want an in-depth diagnostic of the product. I don't care about the nitty gritty of that stuff. I want a power bank that can keep the phones going that works and isn't something I need to fool with or worry about it going out. In the couple of months that we have owned this, it has impressed me on all fronts. I'd recommend this to anyone that is in the market for a power bank.

great power bank

Works great! Has a great battery life. Have used it on my Pokemon Go walks and while it is a bit heavier than most would like (sags my pockets) it works very well! I recommend this purchase.

I absolutely love this product

I absolutely love this product. Once it is charged, it will easily last a weekend so when I'm out and about I don't have to worry about how to keep my phone charged. I also take it to class with me to keep my devices charged because I don't have easy access to an outlet. Well worth buying!

Worth it over other more expensive brands with less features and less mAh for the price.

It works great with charging on the go or stationary. It isn't so heavy that it's a pain to carry. It charges my phone fast and has plenty of capacity to recharge it multiple times. I used it to charge my Surface 3 and that worked great. The Surface 3 did drain it much quicker than my phone but it was nice to know that in a pinch it works. I have used it for Pokemon Go and it wasn't much of a hassle to have it in my pocket with a cable coming out. Also, I have used it with a backpack which was nice since you didn't have your pocket filled with it. The flashlight is a nice addition even though I haven't really needed to use it much. I usually always default to using my phone's flash for a flashlight. The two included cables are short but they get the job done, and I have used them here and there when I don't need a lot of reach. Lastly, another main bonus for this huge capacity power bank is the dual ports for charging it. For example, using two phone chargers charge it easy and relatively fast. It makes it not seem like it's taking forever to charge it when you want to use it later. Without dual charging it still isn't so bad for a full charge.

Great product for a 20000mAh

This thing is big, but its powerful. One press of the button shows the current battery charge and 2 taps turns on the flashlight. The 4 USB's are quite nice for charging multiple devices at once. The fact that there are 2 micro usb's to charge the thing up is even better with a size of 20000. Very happy with purchase

Great for days when you need to use your phone...a lot.

I use this pretty much every day to keep my S5 Active running at work. There are days where I'm on the phone all the time, or places I have to go with limited signal that eat my battery. I've taken it camping a few times too. It has enough juice to last all weekend and functions as a weak light at night.

Like it very much!

Takes awhile to charge, but so far, it's amazing. Charges 2 note 5s, two LG Bluetooth, and s4, and still 3 lights on the display!

A great external battery solution for long trips, or other times when you will be away from power for an extended period of time.

All charged up!

Excellent product, and easy to use. Delivers what's advertised and at a reasonable price point. Charges overnight and is then a real help keeping an iPad live when flying cross country or internationally. This was a good buy.

Must have for travel

I own several power banks from small to large, and this is my go to for every occasion from airport to camping, and even just sitting on the couch away from an outlet. The bank hold enough power to charge everything I use, recently used on trip out of the country and was able to keep my tablet, phone, and wife's phone charged between and during flight and layovers on a single charge. Best part is that when I do manage to drain this bank it has 2 separate inputs (micro usb) to charge the thing back up twice as fast. Only draw back here is the weight, but with any power bank the more storage the heavier it will be. Would defiantly purchase again, and has worked flawlessly for several months now.

Fantastic.

worked great. I can't speak to the capacity but i brought it along on a fishing trip to keep my tablet, phone and speaker charged. Listened to music all day and all night and there was still some energy left in this thing. I love the 4 USB ports.
