Get ready for heat: If you're running anywhere close to the rated wattage (or above), expect your USB-C laptop charger to feel toasty to the touch.However, they usually donвЂ™t come with cables, so youвЂ™ll need to buy a USB-C to USB-C cable of appropriate length, usually at least six feet, if you donвЂ™t already have one. Bring your own USB-C cable: Most USB-C laptop chargers come in wall wart style, with a single chassis and prongs that fold inward for compact storage.In order to help you find the best USB-C laptop chargers, weвЂ™ve tested the latest GaN-powered models from major brands such as Anker, Aukey, IOGear and RAVPower. But not all of these adapters are created equal, with significant differences not only in design and ports, but also in the amount of wattage they can deliver, which is often higher and sometimes a little lower than advertised. The marketplace is flooded with GaN-powered USB-C laptop chargers with wattages that go all the way up to 100 watts (the maximum allowed by the current USB Power Delivery standard). The latest, greatest and best USB-C laptop chargers use semiconductors made from GaN (Gallium Nitride) rather than silicon, which allows them to handle more current in a smaller space.

Fortunately, if your system gets power via USB-C, you can easily find a third party charger that weighs less, looks better and may even have additional ports for charging other devices at the same time.
