When you are busy on the go and need a lot of juice, powerbanks come in handy. But sometimes one isn’t enough, and if you have more than a couple charging them with all those cables can get messy real quick. Koonhome, a Chinese company known for their smartphone cases, just answered this challenge with their all-new stackable powerbanks. The modules are available in 3,000mAh and 6,000mAh and they magnetically click on top of each other and can be charged with a single Micro USB cable. They come in various colors and you can grab one, two or more on the go whenever you need them.
