Today is our third day without power and the gear batteries started failing one by one. There’s only so long you can run before needing to charge those batteries and that was today. I remembered getting a power inverter for running gadgets in my car and I rummaged around and found it. It is the Slim Line Inverter with USB Power Port by AIMS Power. The Slim Line inverter is a tiny gadget in its own right, only 3.25 x 4.75 x .75 inches and weighing 6 ounces. It is designed to convert the 12 volts of DC to 120 volts of AC power to let you run your gear in the car. I am impressed with this little dandy so far. The inverter is the little silver box in the lower left of the picture at right. You can gauge the size by the white Apple adapter to its right.
I plugged the inverter into the cigarette lighter in my car and the MacBook Pro adapter into the inverter. It was then a simple matter to plug the MBP adapter into the notebook and let it charge away. The inverter has a fan with a vent so it’s important not to block it so it won’t overheat. I’ve only been charging the MBP for about 20 minutes and it’s over 25% charged according to the LED indicator on the battery. I’m going to let it charge it up completely and then charge the second battery which will provide me with about 7 hours of new life for the Mac. The only downside to the inverter is the single outlet so you can only use it to charge or power one device at a time. It does also have a USB port for charging phones and PDAs which is handy though.
