It did not charge at all!

A good idea for the design and relatively cheap price (would have earned more stars if it had worked), and thought to be an impossible-to-fail product for to its simplicity, but it failed to charge at all which is quite uncommon at least my experience for rechargeable gadgets.  Thus,  it earned only the one star since it becomes pretty much useless, except the use of the timer to operated the cellphone.  But then, what's the point!

There's nothing I did except have it plugged into the wall and the third day, I went to charge my phone and it simply wouldn't work! I tried other cords to no avail. I took the flat USB cord that came with it and used it fine to plug into a computer and another separate wall plug and it worked. It's the square wall plug in. Sending back! After several attempts to buy cheap, I finally bought Samsung wall chargers. Before buying this, I bought fenzer chargers and they never charged correctly.

It did not charge my phone at all. I charged it for 6-8 hours and it still didn't charge it.

I cannot even charge this unit!  The charge light stays red after 6 hours of charging.  If I cannot get this to work in the next 6 hours, I am returning.

We received this for the baby shower and it was super cute to use until the charge died. We plugged it in for a few hours - nothing. Plugged it in overnight - nothing. Took it apart and plugged just the tech in - nothing. Can't return it since it was a gift so I guess we'll just toss it. Makes me sad.

I pulled it out of the box today and attached it to my laptop but the laptop never charged. Instead, the laptop eventually died on me. I am contacting the seller for a refund or replacement.

I absolutely loved it for the TWO days that it worked. Very disappointed that it won't charge, it won't reset, won't turn on or anything.. The screen is only showing 11:27..... The last time it was turned on. RETURNING.

I should have trusted the other negative reviews of this product.  It didn't deliver a charge to the phone at all.

I bought this in hope that it would charge my slowly dying computer. Not only did it arrive two days late, but it doesn't even work! It promised it would fit my computer, and it doesn't. And, it also feels way lighter than the original charger box. I wouldn't doubt that its empty! Save your money and buy a different product!

 Now, I have to find a new charger...

This battery would not charge\Shipped dead on arrival. After I installed the battery and plugged it in; I realized it didn't have any charge.  I tried to charge it and it showed a solid battery icon with the phone off, appearing to be fully charge. It was NOT. After leaving it on the charger for at least 20-30mins the screen stopped showing the black and white battery indicator and retained a completely black screen.  No dice people! DO NOT BUY unless u want to send back.

Junk, it would not charge. Never worked from the time I took it out of the box.
You shouldnt have to go through the hassle of returning and hoping the next one works.

I received this yesterday and was so excited because of the reviews that I read.  After plugging it in to charge for hours, it still will not charge.  What an incredible disappointment.  There are no trouble shooting instructions, no way to make it work, and now I have to go through the hassle of returning and shopping again to try and get what I need.  What a pain.
