We’ve all been there. You’re out on the road, doing your thing, and then you whip out your portable device only to discover that it’s out of juice. If you’ve got an iPad, Element5 has you covered. The Mini L Solarbag is exactly what you think it is; it’s a bag with a solar panel on it.

The carrying bag is clearly designed with the Apple iPad in mind, but the dock connector on the inside will work with any variety of iOS devices. The Swiss-made Mini L Solarbag features the BluCell solar panel on the top flap, which is presumably where it’ll get the most sunlight when you’re walking down the street on the way to Starbucks.

The eMicro battery found inside the bag is supposed to set “new standards at recharging Smartphones and iPads,” giving up to five extra hours on your iPad or three full charges of your iPhone. Element5 doesn’t say, but if this is anything like other solar chargers, getting the eMicro battery to fully charge is going to take a while. Maybe leave the bag by your windowsill when you’re at the office.

Though going green by way of this Swiss solar bag isn’t going to come cheaply. Available in black or white, the Mini L Solarbag is a whopping $400. Ouch, you’d be better off going for a Voltaic Spark at a $100 less.
