There a lot of smartphone battery cases. Some strive to to be the thinnest while others brag about capacity, but what intrigues me most about BuQu’s new PowerArmour battery case is it’s one-piece design. Most cases require being broken down into two or three pieces.
The platinum gray case can extend run time up to nine hours, and BuQU says with a 2.1A USB port, it can charge 20 percent faster than other cases. The charge indicator and on/off switch is on the back of the case. It measures 5.4 x 2.5 x 0.7 inches and weighs in at 3.2 ounces.
