Identify your Mac power adapter - Apple Support discusses that subject.
Briefly stated, you can use any power adapter that fits your Mac without any ill effect. Power adapters that don't provide sufficient power won't charge as quickly, or might not charge it at all, and power adapters capable of providing more power than the Mac can use won't charge any faster.
Cables are also important. Some USB cables are inappropriate for charging and cannot be used for that purpose.
