We've all had that moment where our mobile phone has died right at the point when we needed it most. Well, tech company Lenmar has a solution or two, or three.

The new Lenmar Helix Portable Power Pack features three USB ports for mobile phones and tablets, with the ability to charge an iPhone up to four additional times and juice up an iPad before needing to be recharged—all while on the go. It's practically a huge battery you can carry around.

Although the price tag on the device might be steep ($99.99 plus taxes and shipping and handling) it'll probably be very beneficial in the long run, especially if you find yourself out for long trips with your chick, or if you're riding the subway multiple times a day before you make it home.
