Perhaps just as important as the Aukey PA-B5's output is its size and weight. When we pulled just 65 watts, the Aukey Omnia PA-B5's temperature hit just 119 degrees Fahrenheit, which is in line with what the coolest 65-watt chargers. However, if it's not pulling close to the maximum - as laptops rarely do - the charger will be quite a bit cooler. When outputting either its maximum wattage or just below its rated wattage, the Aukey Omnia PA-B5 can get pretty hot, returning skin temperatures of 165 degrees Fahrenheit (73.9 Celsius) and 154 degrees (67.8 Celsius) respectively. This super-svelte charger can not only hit its rated 100-watt output capacity but, in our tests, it exceeded that number by more than 10%, delivering 113.7 watts (19.6V / 5.8A), which is more than the USB-PD standard even supports.

If you’re using a 16-inch MacBook Pro or another USB-C laptop that requires more than 65 watts of juice, the Aukey Omnia PA-B5 is your best bet. You can use this port to charge a mobile device or even power a Raspberry Pi, but it will take a certain amount of amperage away from the main port.īest USB-C Laptop Chargers You Can Buy Today Mind the second port: Many chargers also come with a second port that's either USB Type-A or USB-C.

You can get a cooler skin temperature by purchasing a higher capacity charger than you need and running it at less than its maximum. In our tests, after 20 minutes of running at one watt below their rating (ex: 64 watts on a 65-watt charger), temperatures ranged from 119 degrees Fahrenheit (48.3 Celsius) to 154 degrees (67.8 Celsius).

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 don’t come with cables, so you’ll need to buy a USB-C to USB-C cable of appropriate length, usually at least six feet, if you don’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.
