It’s a small thing, but it could make a big difference in your travel bag. Plugs: To fold or not to foldĪfter you decide how much power and how many ports you need, just one question remains: Do you want the plug to fold or not? Some chargers have folding pins to protect the adapter as well as other items if you toss it in a bag, but Apple’s 20W charger and a few others have protruding prongs. You can even get a mix of USB-C and USB-A, depending on your needs. If you’re going to be regularly charging more than one device at a time, buy an adapter with at least two ports-some have as many as four ports. Even Apple has now caught up with its latest dual-port power adapter. Many third-party adapters offer multiple ports on a single wall charger. Unless you’re buying one of the models here-which are all GaN except for Apple’s adapter-be sure to check out the dimensions in the technical specs. For example, the Anker PowerPort Atom III is 35 percent smaller than the adapter Apple supplies with the 13-inch MacBook Pro, despite delivering the same 60-watt charge. That’s due to the newest charging tech, gallium nitride (GaN), which allows for adapters that are significantly smaller and more power-efficient.Ĭharger makers have already begun replacing the silicon inside power adapters with gallium nitride, and the size difference is significant. Apple’s chargers have always been light, small, and portable, but some third-party adapters make them seem downright bulky.
