my Magsafe adaptor wire burnt off and Apple original Adaptor is too costly (7500/-) Is there an alternate way to charge Mac book pro mid 2012 ? Also, is it safe to buy compatible chargers which cost 3k?

Also, is it safe to buy compatible chargers which cost 3k?

"3k" what? We cannot see where you are and can't know if you are asking about pricing in dinar, rupees, yen, lira, or ducats.

Also the power adaptor model for a 13-inch MacBook Pro depends on the model year. We don't know that. Please help us help you by posting more information.
