It also powers the system if you choose to operate without a battery.Ĭompatible only with MacBook Air featuring MagSafe 2 power port. This power adapter recharges the lithium polymer battery while the system is off, on, or in sleep mode. An AC cord is provided with the adapter for maximum cord length, while the AC wall adapter (also provided) gives you an even easier and more compact way to travel.ĭesigned to be the perfect traveling companion, the adapter has a clever design which allows the DC cable to be wound neatly around itself for easy cable storage.

When the connection is secure, an LED located at the head of the DC connector lights up an amber light lets you know that your notebook is charging, while a green light tells you that you have a full charge. Mac Book Pro Charger - 100W USB C Charger Power Adapter Compatible with MacBook Pro 16, 15, 14, 13 Inch, MacBook Air 13 Inch, iPad Pro 2021/2020/2019/2018 and All USB C Device, 7.2ft USB C to C Cable. In addition, the magnetic DC helps guide the plug into the system for a quick and secure connection. It also helps prevent fraying or weakening of the cables over time. So if you’re wondering why your laptop isn’t charging even when plugged in, it could be an issue with the charging port or the charging cable you’re using.The 45W MagSafe 2 Power Adapter features a magnetic DC connector so if someone should trip over it, the cord disconnects harmlessly and your MacBook Air stays put safely. Specifically, not all USB-C ports support Power Delivery and not all of them accept charging. The other thing is that not all USB-C ports are the same. This means that not every USB-C laptop will be able to charge at the same speeds, no matter how powerful the charger’s power output. The newest MacBook Pros support a max power input of 96 watts, for instance, while the newest MacBook Airs are significantly less than that. Different laptops support different power inputs. A lot of it has to do with how much power the laptop can take as well. It’s not just about how powerful the wall adapter is. Not all laptops charge at the same speeds. There are even rumors that Apple will include a 65-watt GaN charger with its next MacBook Pros. Anker has been a leader in GaN chargers, releasing the PowerPort Atom PD 1 last year, but a lot of other charging companies are catching on. Essentially, it’s a new material that is way more energy- and space-efficient than silicon, the traditional material used in wall adapters, so GaN chargers can be smaller and lighter, but also still really powerful. GaN stands for Gallium Nitride and it’s a new buzzword in the world of charging technology. What is GaN? And how does it affect charging? For instance, Anker’s 18-watt Power Delivery charger and Aukey’s 18W PD Fast Charger are both designed to fast charge your smartphone, not your laptop. PD technology can be integrated into many devices whose power outputs can range from 18-watts to 100-watts. That said, just because a charger supports PD, doesn’t necessarily mean it can charge your laptop. And yes, PD is the only charging standard that can charge a laptop. Power Delivery (PD) is a charging standard that allows a charger to output higher currents and higher voltages, thus allowing you to charge your smartphone or laptop from 0% to 100% in a shorter time. What is Power Delivery (PD) and does the wall adapter need it? A safe range for a wall adapter is between 45-watts and 96-watts - those will definitely be able to charge your laptop (with normal use). For instance, if you have a larger laptop or your running heavy-duty programs, a 30-watt wall adapter might not be able to charge your laptop as fast as you’re draining it. This, of course, will vary depending on how intensive your power consumption is.

Typically, a wall adapter or portable charger has to output at least 29-watts or 31-watts to give a laptop more power than it consumes by just being on. Is there a minimum wattage required to charge a laptop? If you’re looking to have some of the most common questions about laptop charging answered, look below. The confusing part is that not every USB-C wall adapter is capable of delivering enough juice to charge your laptop. The good news is that we’re living in a day-and-age where basically every new laptop charges via USB-C - it doesn’t matter if it’s made by Apple, Dell, HP or Lenovo.
