MagSafe 1 or 2 for MacBook Pro 2015

I have a 2015 MacBook Pro and need to know if I should be using a MagSafe 1 or 2 charger. I've searched around with Google but so far I've found conflicting information.

I recently ordered an 85W MagSafe 2 (T-style) car charger and while the green light comes on showing power coming in, the menubar battery doesn't show the lighting bolt in the UI.

Need to know if it is just defective or if I'm buying the wrong charger.

Solution 1:

Those two styles for the glorious magsafes are physically different. If it fits without an adapter you have the right prong for your machine. An overview for which Apple (don't call it)laptop mobile devices need which can be found here.

The menubar not reflecting what the charger is telling you may be caused by something else. You indicated that your charger is declared as having the right power rating. Since it is apparently not an Apple product giving you problems, you might want to check if it really delivers the amount of power adversed.

Trying an SMC reset and making sure the connector for the charger on the MBP is clean would be the next steps. Defective chargers cannot be ruled out entirely. Since it's new, go let it be checked out.
