The very best external battery power bank I have ever had!!!!

Now, I have a dead power bank that won't come back to life

when everyone else at the airport is in the corner like a hobo plugged into a sketchy outlet, I just break out this power bank and charge all my gear.

Worst power bank I have ever seen......complete junk not worth the price........dropped with in 2 inches and does not work

The first impression I had of this KMASHI 15000mAh Portable Power Bank was that it was great.

It was working very well but suddenly not charge and for the moment I stop loading

So far is working very good and charged my devices very quick

Works, 2 barging led lights already stopped working though within first week or so

The new unit is working fine so far and we have been using it for more than a month.

This is my second Kmashi.. while my first one was a dream come true unfortunately this one has died on me and no longer works after only 2 months of use

Best option out there for someone who is looking for a long charge portable battery for a cheap price

great price, lots of positive reviews, so bought it about 2 years ago.

I know I can't expect much at such a cheap price, but it only lasted for about a year with only occasional use.

It does what it says on the box, feel and looks well made, great price

Maybe it's worth the money to get a nicer brand that weighs less, but for my college self, this was a great battery at a great price.

This portable charger can charge your phone a number of times during the day you will have continuous power !!!!

Unit takes forever to charge up, and if you to charge your phone or tablet it takes 2-3x longer than my wife's cheap lipstick charger

I bought an expensive portable charger first at an airport and it only lasted me 2 months

This portable charger works very well and is extremely convenient

This portable charger is one of the most useful things I own.

item as described, works very well with iPhone and HD Fire tablet

A great item to take on a long trip like we took to the national parks in the West

Works as said but is very heavy and bulky not an easy item to carry

I attributed it to a possible defective item and just figured I’d eat the cost since it was already out of the 1 month

Not a small item, does have some weight to it, so not really convenient for small purses.. but is fine in a larger handbag or any backpack.if you are trekking around a city ( especially a foreign one ), and wont have much chance to recharge your phone or tablet, then i can easily recommend this power pak..

I purchased a KMASHI 10,000mAh portable power bank which lasted me about a year

This is a small and Portable power bank good to throw in Backpacks or a purse

The first impression I had of this KMASHI 15000mAh Portable Power Bank was that it was great.

I decided after recent hurricanes and losing power for several days, I needed one for myself.

So I have had this power bank for a couple weeks and it is one of the best power banks I've had in a while

This unit is larger and meatier and has the same good build quality

For the price this is a very good quality battery, and I use it all the time though I have to charge it maybe 1 time a week

Great capacity and really good quality for this low price

This battery is really good quality and I really love how this one has a carbon fiber feel

I'm sad about it, but they do hold a lot of charge and seem like good quality.

If the size truly is not an issue for you then this is a great product.

I used this product for about 4-5 months and it doesn’t work anymore

Great product, have used it many times and would buy it again if I needed.

If you have a faulty product they may be able to replace it for you but ask them anything

This product is really bad because I've used it only once and it stopped working already.

Because of its sturdiness, I can stand it up on my counter and charge my devices and work on them at the same time

Definitely money well spent on a portable charging device.

Customer service required proof that my device became defective

This device will charge my iphone 3 times before it dies, love it.

Super handy to have, and love the fact you can charge 2 devices at the same time

If you remember to charge this over night, you will never have a dead battery anywhere you go.

I would have drained my phone battery each day without it.

This is a great portable battery that has worked really well for me

Great battery stamina, charges phone and kindle fire two to three times on one battery charge

The problem is that it is really heavy and big for being a portable battery charger

They might be the single best thing to have if you're in a situation where your phone battery is dead

Wonderful amount of charge, usually lasts me 2/3 weeks until I need to recharge (I don't use it everyday, usually charge my phone 2/3 times per week)Only bad things are that it takes a long time to recharge, I've left it charging overnight to find out it was still charging in the morning

I've had this thing for months and it still works as promised

The only bad thing is it take a long time to fully charge, but will last for a long time fully charge

Such a great thing to have when a charger isn't available

It holds a ridiculous charge that it can last for days of use

Great capacity and charges phone quick!Does take a long time to charge the battery, but that is understandable considering it has the capacity of 5 phones in one

This portable charger holds a very good charge and I can see it charging my phone fully for 3

Works very good charges my phone about 8x before need recharge pnl downside is it takes 11 hours to charge

Nice product hold a good charge, recharge time is quick and gives my phone days of battery

I keep it in my car to charge there or sometimes I take it 'n charge in my pocket - it always works as if I'm plugged into the wall.

After 6 weeks it's not working won't charge only 1 bar

There were times that it would not charge my phone as fast as it used to

If you see this issue with your battery pack, just ignore the bars and recharge once you get to 2 bars

Only lost 1 of 4 power bars and during that time I used it for several hours on the trip.

It's a bit on the heavy side, so I wouldn't recommend it for someone wanting to carry a spare charger in a pocket; but I use it to charge my phone and pad when working in the garden or in the

but you would at least expect a bit more use out of your purchase before it dies.

I've dropped mine once, and ever since then the charging port has knocked loose a little bit and when charging the battery itself the wire has to be in a certain position to charge

works fine but its a bit big and heavy not really confortable to carry

A couple of cons I have for this power bank are that it isn't as lightweight as other power banks and it does seem a bit slower to charge.

I e had great luck with Anker

Considering the Samsung phones that are exploding and burning down houses, cars, etc

Could've burnt my house down.

Still works just fine, but this is a reflection of the cheap plastic housing

Tried to use it last weekend, but it began making a hissing noise and now it does not even charge

It also makes a pretty loud noise when you connect something to it.

The charger is pretty loud and makes hissing noise when I'm charging my phone

I e had great luck with Anker

Another thing to note is that some units make a sort of hissing noise (if you get one with

I have switched cables, devices, etc and it does not alleviate the scary sounding buzz

Again, maybe that's just because of the battery size/capacityEmits low pitched annoying sound: Haven't had a chance to see if that'll happen again

though I've noticed in my first 24 hours of using it is that it has a static sound to it.

As well as my individual charger has been emitting a weird hissing or squealing sound, very quiet
