Cooler Master has announced that it will be on hand and MWC 2011 with its line of Power Fort offerings. I have talked a bit about the Choiix Power Fort offerings before; it's a line of external batteries and power solutions for smartphones and other gadgets.
At MWC 2011, Cooler Master will have some gear on hand at the show that we have not seen before. One of the more interesting items is the Power fort solar iPhone 4 case. The solar case has a small solar panel on the back to charge up the internal battery while you are on the go. Exactly how much power the battery inside the case has is unknown, but those details should be offered at MWC.
Other gear that will be shown at MWC will include the Power Fort 5.5Whs/1500mAh battery that is for any USB device including the iPhone. The Power Fort 2700mAh battery will also be shown off along with a boxy 1500mAh battery. A brand new product will also be unveiled at MWC called the Power Fort Go Music.
