It was only a matter of time before the versatility of those little plastic blocks was put to use in the era of the smartphone. The COI+ Lego Power Brick, a block of Lego which acts as an external battery pack for your phone or tablet, is designed to offer on-the-go charging while adding a little creativity to the mix.

 

The Power Brick measures 72 x 120 x 13 mm (2.83 x 4.72 x .51 in) and sports an On/Off switch on its underside with a grid of typical Lego bumps on its top surface, inviting endless possibilities for plastic constructions.

More practically, the included slanted Lego bricks can be used to create a customizable stand for your phone or tablet, which can then be given a little extra juice through a Micro USB or regular USB port on the brick's side.

Housing a lithium-polymer battery with a capacity of 4,200 mAh, the 115 g (4.05 oz) Power Brick is capable of charge speeds of up to 2 A and is compatible with "most smartphone and tablets."
