Another new product from Genius is the ECO-u821, a compact 8000 mAh portable PowerBank for multiple smart devices. This gadget is extremely handy for situations like CES 2014 where you're walking around taking pictures, texting messages and making calls, and there just isn't enough battery juice for one full day.
What's great about this peripheral is that it can charge two devices at the same time, and is compatible with nearly every 5V Micro USB device on the market, making it a great recharging solution for most smartphones, tablets, media players, game devices, e-readers and so on. The ECO-u821 also features a built-in USB output cable so that the only cable you need to worry about is the one for the second device.
Specs show that the ECO-u821 is rather lightweight, weighing only 0.47 pounds. This should make the recharger easy to stick in a back pocket or purse for on-the-go charging.
