I bought it to bring in my vacation in Orlando, FL. It has been terrible. I charged it fully the night before. 4 solid bars. Took it to Sea World and it wouldn't charge my phone. I tried,both ports, nothing. I am so disappointed in the product.

It was difficult to figure out how to use, it's heavy and gets warm. Once you figure out how to use, it works as it's intended.

The price was great, but not having a cord to charge it or to plug into my phone was a real disappointment. BTW a plug did come with it, but it doesn't fit any of my apple devices even tho it says apple on the box and it is not one I can charge the device with. so when I went to buy all that I need with it. Not so great a deal.

It is much heavier than I expected.im not sure if weight was in description. If so I missed it. It is a gift so I have not used it and can't speak to usability.\nI think my grandson will like it. I like that it should store charge for six months when not used.
