Mobile devices are essential in today's society, and the last thing a user wants to see is the red battery on an iPhone. However, that's no problem with the Power Tube 4000L, a portable charger by Mipow. The 4000mAh battery capacity will juice up a device with its built-in female USB port. The extra male USB connector will recharge itself through powered USB equipment. By simply pressing the on-and-off button, the battery level can be checked. Red means 15 percent, orange means 15 percent to 40 percent, green means 40 percent to 70 percent and blue means more than 70 percent charged. This portable charger is available in white, black, purple, red, dark blue, sky blue, gray, yellow, neon green and pink. It is compatible with the Apple iPhone 5.
It is currently available for $69.95.
