    Went to Scotland for two weeks and had two Samsung phones to keep charged up. The airlines want it as carry on baggage but there wasn't a problem with the power rating. Never had any problems with the Power Bank so I went and had to buy another one. My girlfriend keeps taking mine and forgets to return it!

    This power bank isn't the greatest. It turns off during use. It doesn't give a lot of juice either. It could charge 45 hours and still give 5 minutes of charge. I would not recommend.

    The energizer battery works perfectly. I love it. I use it in the airport. I use it traveling. I use it at home. If I don’t have my phone fully charged it’s just such a great product.
