Qumo Premium Power Bank [13000 mAh] Ultra-Portable External Battery Charger [Multi-Functional Compact Size Universal Power Bank] for Smart Phones and Other Digital Devices

This is perfect. Exactly what I was looking for. I can do two items at once AND it has a flashlight. I might get another just to keep in my car!

I have not tried the product yet, however the protective barrier was knocked off the battery. i put the pieces back on and now there is a rattling noise within the device. i am looking to exchange the product.

So power banks are tricky things. I fully plan to update this review as time passes to see if this power bank holds up. As I have had several power banks in the past (though they were much cheaper than this one) that ended up falling apart or that just stopped charging as well. Some stopped working completely after only a few uses.All of ^^^ that being said though FOR NOW this power bank seems to work really well. It's big and bulky which is kind of a bummer, but for me is not an inconvenience (thus why I did not deduct a star). I have been trying to get a few more power banks since my husband and I started playing Pokemon Go. The thing is killer on batteries and so having the spare power is a must. So since I do not need to tote it around everywhere I just keep this in a backpack specifically for Pokemon hunting. There for the bulky size of this pack does not bother me. It is something that you should keep in mind though if you plan on keeping it somewhere like a purse. I have not tried charging a device with lower battery with this to full charge so I can't say just how much it charges. I can say that in the course of a day of hunting it kept my phone from dying when it was on like....40% battery and when I unplugged it to plug into my tablet, just to keep it from dying due to playing Pokemon Go it was not actually low on battery, that my phone was charged fully and my tablet did not die. There was even some battery to spare as there was still one light on after having used it. So it is a decent little pack. It also seems to charge pretty quickly which is a big bonus. The cord provided is not very long, but it gets the job done.Now here is a warning! I did not have an issue with the ports on THIS pack. However I got to test a smaller version of this same battery pack from the same seller as well as this larger battery pack. The smaller one I never even got to charge as the metal bit in the port you charge the pack from fell inside the battery pack when I plugged in the cord. Now let me repeat. I did not have that issue with this particular battery pack. I did have it with the lower power version of this one. Since they are pretty much the same product I would thought I would throw that out there as something to watch for.

This power bank/USB battery appears to work very well. I've only had it a few days, but it's charged everything I've connected to it, and it itself has charged up nicely from the wall. Functionally, it does everything it promises to.It has one 2.1A output, and one 1A output. The 2.1 is faster, obviously. The 1A output doesn't really bother me (if I'm charging two things, one is usually slower or smaller), but the 1A input does annoy me a little. Many batteries have a 2.1A input, which means they can be charged from the wall, and ready to go, in about half the time. I have noticed that the batteries with this feature tend to be much more expensive, though, so it must be expensive/difficult to implement. At this price, I won't hold the 1A input against the Qumo, but you should be aware that there are other (more expensive) options.The one thing that did cause me to take one star off was quality. First impressions weren't great - the thin plastic box it came in was split all the way down the side. When I pulled the battery out of the box, one end had slightly separated, and had to be snapped back together. This came in an Amazon box with a few other items, none of which had the least sign of damage. As I hold & feel this battery, I can feel a little movement along the middle & the seams - something you don't want to feel in your electronics. There may be a reason this one is so cheap. This may be perfect to use around the house, or to keep in an emergency kit, or something like that. But I'm not sure just how well it will stand up to the rigors of travel or something like that.Good design, good functionality, great price, decent quality. That comes out to 4 stars in my book.

Lets start off by saying this is a perfectly nice power bank. i am only knocking it a star because i have a nicer one. and to be fair that nicer one was more expensive. so use your value judgement here on price point versus form factor.This is a good power bank its got a good mount of juice at 13000 mAh. Its not ugly, they have a decent pattern on it which breaks up the acreage and also helps with the grip.I would have passed on the flashlight. Its not a good one, and you really dont need it. If your lose it you can lose the button on the unit and make it slightly smaller as well as cheaper. Alternatively you can put a flashlight in here worth having.so here is the deal. I think this thing is to big. OR if its got to be this big, its the wrong form factor. OR if its this big because your using 6 18650 cells then why isnt it a lot closer to 20,000 mAh? Its just to long and to heavy and to clunky. That flashlight doesnt help either.Look I did get this thing for free, so im not complaining about that. I get some stuff for free and I promise to review said stuff. so maybe if i had paid full price for my other more expensive nicer battery back i would be more appreciative of the $10 i would have saved buying this much larger unit. but that other one has the same mAh and uses only 4 cells. so its smaller and they dont lay them all out next to each other so it fits the hand easier. But it is what it is and i think I would pny up for a better cell in a better form factor.

Too big and too heavy...!
