The trend in external battery packs for charging smartphones and other small devices is to make them smaller and more compact. The Coi+ Power Brick doesn't care about being tiny. It cares about being bumpy -- bumpy enough to offer a base for building Lego creations on top.
The 4,200 mAh power pack comes with four slanted official Lego bricks that can be attached to turn the device into a stand for your phone. Chances are, if you're interested in buying this, you already have a Lego stash of your own to add onto it. You could build a little throne and set your iPhone in it, or turn it into a landing pad for your "Star Wars" Lego ships.
Once you're done playing (or in the middle of it), you can plug your smartphone or tablet into the pack's USB port for a recharge. The ports are on the side of the device, so as not to interfere with the space for building your toy creations. There's a power button and a set of indicator lights on the backside to show how much charge is left.
The Power Brick is currently available for preorder for $49, with a scheduled ship date of mid-March. There are smaller and more powerful external batteries out there, but perhaps the world would be a happier place if more random technology items were Lego-compatible.
