DC-DC Power Adapter
Power My Mac has launched a new car and airline charger for MacBooks, the DC Power Adapter. Designed as a DC-DC converter with regulated output voltage, the device has been factory set to 16.5V. The adapter is equipped with short-circuit protection as well as an internal temperature limit cut-off, and should support all MacBook, MacBook Pro and MacBook Air models.
Available in 60W and 85W versions, the adapter is capable of powering and charging a person's Mac with any 12-30V DC power source. Bundled with the device are two input cables -- for cigarette or airline outlets -- and an output cable meant for Apple's MagSafe connectors.
The 60W adapter is compatible with MacBook and MacBook Air systems, and is priced at $200. The 85W version supports all MacBooks, and costs $220.
