But in 2015, Apple resurrected the name with an ultra-light, ultra-portable MacBook model that lasted a few more years until being just recently discontinued.
Apple chargers for a MacBookįor a long time, MacBooks used to be the only laptops Apple would make, and the last ones of this original type were made in mid 2010.

With your MacBook information in hand, navigate to the appropriate section below to see the kind of Mac charger you need. It’s not only the Air or Pro that you need to know (for which you might just look at your monitor’s bezel), or even the screen size, but the year and even the part of year it was manufactured in (e.g. Given a variety of MacBook chargers available, the most prudent thing to do before buying one is to check your MacBook’s model. While MagSafe and USB-C have been using the same connectors for all models, MagSafe was split into a T and L-shaped connectors, each with its advantages and disadvantages. The last thing to consider is the shape of the connector. The latter is used for the newest MacBook models. As of 2021, there have been only three versions released: MagSafe, MagSafe 2, and USB-C. The second thing that the MacBook Pro charger name tells you is its type. If you go with a charger below whatever’s required, your MacBook will probably not charge at all. That’s why it’s so important to be careful about picking the right charger for MacBook Pro. Naturally, the higher it is the more power your Mac receives.Ĭontrary to the popular belief, however, getting a higher wattage Apple MacBook Pro charger wouldn’t charge your Mac faster, but also wouldn’t damage your Mac, given that it’s officially supplied by Apple. Looking at all the variations of MacBook Air and MacBook Pro power adapters, you’ll notice that the first thing they specify is wattage, which can go anywhere from 29W to 87W.

The bigger dangers are when the power source is at the wrong voltage.Try free Essential Differences In MacBook Chargers When the inverse situation,having a 12V 20A charger and having a device connected to it that only draws 0.6A, the load (device that is charging) will only draw the 0.6A it needs, even if the charger can supply 20A.Īs far as AMPS go, the load draws what it needs, or less if it is not available, and the power source supplies what the load needs by virtue of the laws of physics, unless it CANNOT. There is potentially more danger is using a charger rated lower than the load requires, but usually only if there is no current limiting circuit or those circuits fail. Bigger Voltages means you can deliver the same wattage at lower currents (which is the most dangerous part of electricity) So when you plug in a PD charger, there is a digital negotiation of rates, once that occurs, the charger will set the voltage to the desired rate and allow current to flow as much as is needed, or as much as it can.įor instance, if you have a 12V 0.6A charger, it can only deliver 0.6A at 12V, usually that means that it is current limited, or that having a load of over 0.6A will cause the voltage to drop below the rated levels. PD simply allows the negotiation of charging voltages, and the charger circuit and the draw of the loads circuit will determine the rest. (the Apple 5 Watt charger that has come is most phones since 2007 is 5V 1A or 5V x 1A = 5W) That's why on many older USB chargers (before PD) they were all 5V N Amps. I can supply that V Volts at a current UP TO I AMPS, or in terms of the POWER, P WATTS (which is a function of voltage and Current). The TL DR is to think of a power adapter (the general sense, putting PD aside for now) as a device that says: I supply power at V Volts. In general, power adapters will only ever deliver the power they need to.
