Innergie's mCube 90 isn't quite what you expect at first. Though you might think that it's an emergency charger in the style of the Callpod Fueltank, it's actually a universal charging adapter for powering multiple gadgets at once. You can use it with your cell phone, of course, but it also supports laptops and Netbooks. On the whole, it's a quality product with solid construction. The design is a little perplexing, and we don't like that we have to pay extra for phone-charging tips, but it does its job well. The mCube is $99.99, which is rather expensive.
The mCube 90 and its various parts come in attractive packaging that includes a soft zippered case. The power adapter is a white rectangle that measures 5.07 inches by 2.76 inches by 0.93 inch and weighs 9.28 ounces. Innergie claims that the mCube 90 is the smallest universal power adapter. While that might very well be the case, the mCube 90 isn't exactly featherweight. On the exterior, you'll find a plug for the AC power cord, a USB port, and a DC output port for notebooks. There's also a LED indicator.
The adapter actually consists of two parts that separate near one end. The smaller part (the subunit) is used as the conduit for powering your Netbook or phone while in a car or on an airplane. On one end is a proprietary connection that accommodates the DC cable for your car's cigarette lighter. That cable measures almost 2 feet, so it should fit most environments. On the other end of the subunit are the aforementioned ports for the USB phone cables and the DC cable for notebooks. You'll need to purchase the airplane cable separately.
