To use the mCube 90 to power your phone or laptop from a wall charger, you must reconnect the sub unit with the main part of the adapter. The AC power cable uses a proprietary connection, but it measures a convenient 5 feet. We're not sure why the Innergie designed the mCube 90 in this way--we think it would be easier if you kept the adapter in piece no matter what you were charging. Also, we'd prefer if the various cable ports were consolidated.
Unfortunately, the mCube 90 doesn't come with any phone tips in the box. You must purchase them separately for $7.99 per manufacturer. Each package includes a retractable cable and the various tips for that manufacturer. The Motorola kit, for example, comes with mini-USB and micro-USB tips. Other kits are available for LG, HTC, Nokia, Sony Ericsson, RIM, and Samsung phones. That leaves a few manufacturers--Apple, PCD, Kyocera, Pantech, and Palm--out in the cold.
The phone cable uses the USB port next to the DC power cable jack. The cable stretches to 2.5 feet with the phone tips connecting neatly at one end. We tried powering a Samsung SGH-T349 and a Samsung SGH-A177. Both handsets and an IBM laptop charged in the normal manner. One particularly nice feature of the mCube 90 is that it can power a phone and a laptop simultaneously.
