There is no sense to deny, that most technologies changes constantly. Tvs, cameras, laptops and iPhones. Compare one of them with its brother from 10 years ago and see, that it can be almost beyond our recognition. Well, except one, may be-batteries. I can’t say, that this technology hasn’t changed at all. But those tiny batteries, that keep our devices measured in weeks and not days or hours, are above our attainment.

Well, there are the Morphies Juice and Air power sleeves, which are perfect, if you know in advance that you’ll need an extra power for your batterry, or an external battery pack, that can be used as a charge for your phone.

The Digital Treasures Powerflask is a new approach to solve the problem. This tech is a pack that can charge an iPhone and one or two iPads at the same time. It looks like a quality product with its metal at top and a leather bottom with contrasting red stitches and won’t be out of place with your stylish iDevices.

There are three ports at top: two USB ports with a small red LED that lights up when it’s used; and USB port for charging it. The first port is used only by phones, while the other is suitable for both a phone and iPad. Besides, the flask includes two micro-USB to Apple connectors to charge two iDevices. The flask can be charged from main power or, for example, from a laptop.

The capacity of the Powerflask is equal to 13,000mAh, that is enough for charging the iPad’s and iPhone’s batteries. 12 hours-and both devices are still fully-charged and are in the same state as if they have just been charged. Of course we need remember that the iPad 3 and 4 need twice the battery power, so the use of the Powerflask will be less.

One more advantage is its size, that allows to carry it in your pocket or a handbag. The Powerflask has almost the same height as an iPhone 4, but it’s a little bit thicker and wider than it.
