Question: I have an old MacBook Pro 17" with original Magsafe. Will this work in the car for me?
Document: It charges my Macbook Pro 15&#34; really well. It charges it faster than others I have tried. I also like the extra usb port so I can charge other things too.However, when I received the car charger, it appeared used, or like it was put together from an old Macbook charger found in a junk yard. I have not used mine a whole lot so I don't know if it will work for a while or die after a month of high usage.
We're going on a long trip and needed a car charger. I received overnight shipping as promised and the charger is reasonably priced.At first I was disappointed as this is for the earlier version of magsafe charger - I am a computer user, but not a geek and had no idea. So understand this is NOT for Retina Macbook Pro. The adapter, available on line at Amazon or from the Apple Store, converts this to charge the retina.
Worked excellently for me, keep my Macbook Pro 17&#34; Notebook fully charged while traveling in my truck on a long vacation.
This adaptor just send sparks flying form the end of it to my computer when I unplugged it from the computer and left a big burn mark on my macbook pro. Luckily my hand didn't get in the way.Two of the pins on the adapter were melted and the inside of the magsafe part was burnt black. This is not a safe item, and you should stay away from this product.
I wasn't sure if it really would work with my MacBook Pro but it fits perfect and charges the battery.
Was a little worried about this working correctly. I've now used it a lot and it works great on my old 17&#34; MBPs
this did not work, it did not have the correct adapter for my Macbook Pro, big waste of money
As an Amateur (Ham) Radio (K6OL) and Navy MARS (NNN0BJB) Operator, this car charger for my MacBook Pro is a "MUST HAVE." Now I don't have to worry about where the nearest power source will be at the end of my 10 hour battery life on my MacBook Pro. Now I'm able to use my MacBook Pro 'in the field' as long as I need.
Spa Magsafe is excellent quality and the answer to my prayers when I need to use my macbook while my husband is driving me long distances.
I was very disappointed to find that it doesn't work with my MacBook. I need to return it. But I haven't had time.
Answer: It should work fine. I use mine with older MacBook Pro 15" with original Magsafe. The new Magsafe uses the 45 watt.
