It's junk.  Don't buy it.  I loved mine.  Stopped charging after 5 months.  They replaced it.  Stopped charging after 5 months.  They won't fix because of the claim of excessive damage.  The device is in excellent condition.  Very small hairline crack on display screen that has NOTHING to do with the defective battery design of the product.  Search the internet!  Many are having the same problem.  They don't even make them anymore.

Edit 4/18/2018: Ive changed my review since they sent me a new charger because my old one was defective. Will update if this one stops working.

Loved this cable. I bought it September 2017. Its now April 2018 and stopped working. The cable is still in great condition so I don't see why it would stop charging.

I loved this thing while it lasted. After about 7 months, it either won't charge anymore or it won't hold a charge more than a few minutes. I've ordered a replacement (different brand that looks like the same manufacturer). Other than that, my only complaint is that it's really hard to adjust the volume without changing the track since both functions use the same buttons.

After 5 months, the cord no longer connects properly to charge phone, great till this point.  Haven't contacted ibolt yet, but will once back home, from being on the road.  I'll update this post once I do.

UPDATE: 02/15/16
This charger completely stopped working after a year of use. It would show the battery fully charged, and then die instantly when plugged into a device. Maybe faulty, or maybe just cheap hardware. I loved it while it lasted.

Works great. Will charge my phone about 4 times before it needs to be recharged (not positive about that). I work in a workshop and I like to be able to stuff this in my sweatshirt pocket while it is charging my phone in my pants pocket. That way I can use my phone anywhere while it is being charged.

You can also easily check how much juice is left in the battery by pressing the little button on the case, which illuminates x out of 4 lights that represent the percent by quartile.

Also, you can plug this battery into the wall to charge it, while also connecting your phone to the battery in order to charge both at once.

Great little usb battery charger.

Well It was delivered August 7th and it was perfect! Now January 12th, a little over 5 months it's stopped charging for no reason.... I'm quiet disappointed...

I loved this when it was working but a charging slot (the little plugging slot to connect USB) got broke (came off) and I no longer be able to charge this speaker even though everything else seems to be working fine.  Otherwise I love it.  Could anyone show how to fix the little slot for charging?

loved it, until it stopped working... after only 5 months.  I wore regularly, and took care not to wear in shower or knock around and yet, I put it on the charger one night, and the next morning nothing.  Moved it to another plug, still nothing.

Fabulous product until ..... IT STOPPED WORKING COMPLETELY!

It is a very convenient charger to have as it has a wall plug connection. I would like to hear back from the seller because only after 5 months of use this product is not working.

At this moment I DO NOT RECOMMEND THIS PRODUCT

I purchased this in December 2017....and was an immediate fan. It charged my Galaxy in rapid time and even my MacBook Air.  I kept it charged and packed in a diaper bag for the inevitable charges needed on tablets for kids. However...it abruptly lost its functionality in July 2018....on a vacation when I needed it most. It was a five star rating and great up until then.

***EDIT: Shortly after commenting on the abrupt demise of the PowerCore C01000mAh, I was contacted by a representative to remedy the problem and the offered me a replacement product. I received the charger very quickly and I am happy to say it is back to being in my diaper bag. Thanks so much to the company for the quick solution.

This item was fine, but stopped charging after about 7 months.  I tried using other micro-usb cables and it still wouldn't charge.  I am trying to see if they will honor a warranty of some kind.  I think they should replace it.  I will update my review then.

Worked great for about 5 months. Now whenever I turn it on it will randomly stop working, but start again if I mess with the power cord or turn it off and on again. But it cuts out every few minutes.

Mine stopped working this week, meaning it worked for five months only. Now needing to buy another one and spend more.

I loved this device so much. I bought it April 5th, it's now July 26th,and I'm sad to say it's not charging properly any more. Very disappointing.

Worked well for a month or two. Since has stopped charging my phone. Case will charge but will not transmit any power to the phone. Was 5/5 but now it is just a 40$ case without charging capabilities. Loved it while it worked!
