XPAL Power and the MacBook Pro

Last year I wrote about hooking up my XPAL Power XP 18000 to my MacBook Pro. My method was a bit wacky, but worked fine. As I was surfing the web the other day, I found that XPAL now offered a connector to the MacBook Pro. Very interesting, I thought, so I looked at it. As Apple has a patent on the MagSafe connector, no company has been able to create a knock off cable. What did Energizer do? Well, they created a cable that connected the battery to a female connector that you then use the Apple airline adapter with MagSafe connector. Very clever, but an added expense.

In my case, I already had the adapter, so I used my free tips for life and for $4, I got the connector. The connector works fine and is a bit cleaner than my solution. However, there is a slight difference between my cable and the XPAL Power solution. The Apple airline adapter doesn’t charge the computer when connected (the MagSafe connector has electronics in it to indicate if it should charge the computer). The cables that I used were regular charger cables, so they charge the computer when the battery is connected. In my case, the battery heated up quickly as it was charging the computer. With the XPAL Power solution, my computer didn’t charge, but the battery stayed cool.

So, having said all that, I think that the XPAL Power solution is better than my solution as I’m seeing better battery life. As I compile code a lot, my main battery only lasts about 90 minutes, so if I can get another 1.5-2 hours out of the external battery, I’m quite happy. I believe that the XPAL Power is now going to give me that (before I maybe got an extra 1 hour to 1.25 hours.
