With new smartphones, tablets, and other portable media devices quickly increasing the speed and power of hardware, it vastly improves the fluidity of these devices. As these devices become much faster, everything inside it is receiving an upgrade - except the battery life. It seems that many companies are pushing for thinner devices as well, but, do we really need such a thin device? I'm sure many people wouldn't mind having a slightly thicker device if it meant better battery life. As a result, many companies have begun developing cases which have batteries built into them. However, this may not appeal to everyone, and of course, these companies cannot develop a case for every device out there, as it would increases their expenses vastly.
Gigabyte's solution to this problem is a 6600 mAh "Power Bank". Since a typical tablet has a 4000-5000 mAh battery, this should allow for one full charge. With phones, this should allow for 2-4 full charges, depending on your battery's size. With a USB interface, this Power Bank allows connection to many devices, as it includes about 5 connectors. It appears that this device can charge your camera, portable gaming device, mp3 player, iPod, tablet, and of course, your phone. It also features a nice dual-digit display on the top which show its charge level. The time it takes to fully charge the Power Bank should be around 12 hours by a USB cable, 6 hours if using the included AC adapter. Suprisingly, this device only measures 78.3 x 77.9 x 22.5 mm, weighing 155.5 g, roughly the weight of a phone. It also shuts itself off automatically after 30 seconds, if no device is plugged in, to save power. It features Charging and Discharging overload protection, and claims to meet RoHS (Restriction of Hazardous Substances Directive). This Power Bank (OTG G66B1) is now available at an unknown price.
