Most laptops come with a charger, and that charger is usually good enough for the job, but it can be very convenient to have a second charger, so you can have one at home and one at the office. Also, portable chargers are a must for traveling. Thankfully, some of the best USB-C laptop chargers feature compact designs, making them the perfect traveling companion.  Also: Best laptop docking station 

This is the perfect replacement for your existing USB-C laptop charger, even if you have something like the latest 16-inch MacBook Pro. The next-gen Gallium Nitride (GaN) technology not only means that this charger is smaller than chargers based on older silicon technology (it’s smaller than the Apple charger), but it also runs cooler. This is my go-to charger for pretty much everything I have that uses USB-C. The SuperPort 4 features two USB-C ports and two USB-A ports with Zen+2.0, allowing you to charge up to four devices simultaneously with a maximum combined output of 136W. The device is small, lightweight, and slimline – plus, it works across all voltages. It’s an excellent travel charger for those who lug a lot of gear around. This flexibility makes this the perfect desktop charger for those with multiple devices that need to be kept topped up. Here you get a 2-port Anker charger, featuring 2 compact Gallium Nitride (GaN) 45W USB-C ports. It’s compatible with most Apple devices, so you can charge your laptop as well as your iPhone or iPad without worrying about connectivity issues. It also has a quick-charge feature that brings your iPhone up to 50 percent power in just 30 minutes. This charger offers an enormous 100W of charging power, which is enough to charge two USB-C laptops and two smartphones simultaneously. Thanks to sophisticated power allocation technology, the full 100W of power are available if you connect a single device to a USB-C port. The LinkOn offers high-power USB-C charging for when you’re on the move. This compact charger features a 90W USB-C port that’s good for even demanding laptops like the 16-inch MacBook Pro, as well as an 18W USB-A port. This has become my favorite car charger because of its power, flexibility, and reliability. I also pick manufacturers that offer a decent, no-quibble warranty. Things can (and often do) go wrong, so dealing with a company that has you covered offers added peace of mind. Then there’s a quality issue. You’ve likely spent big bucks on a laptop, so it doesn’t make sense to connect that up to a cheap charger that you picked up from a dollar store! Most manufacturers take the guesswork out of this for you. They’ll include device compatibility on their package and/or website.
