You will find USB-C adapter cables for charging older laptops – Review Geek

USB-C charger cable
Michael Crider

I love my ThinkPad T450s. It’s loaded with cheap RAM, its dual chamber battery system allows me to keep working all day, and the keyboard is incredibly amazing. But I̵

7;ve kept it on the shelf for a few years because I’ve gone from bulky chargers to an all-USB-C mobile lifestyle. That’s until I found an adapter on Amazon.

See, most laptops made before about 2017 use their own charger of one kind or another, either the old barrel ports that come in so many different flavors that you need a small ratchet set of adapters if you drop it, or something completely unique , like my ThinkPad’s rectangular charger or the older MacBook magnetic cables. So trying to charge any of them from a standard USB-C charger would require some form of Frankenstein mod of the laptop’s motherboard.

Not so anymore. Sellers have started manufacturing charging cables with USB-C at one end and their own charging cable heads at the other. These are more than just ordinary cables – they have circuit boards inside that regulate the current flow and will not fry your laptop or charger. Since my original Lenovo T450 charger cable uses 45 watts (20 volts x 2.25 amps), I ordered this gallium nitrate USB-C charger to match it, and I’m on my way to the races. That’s about a third of the volume of my original charger, and I can also use it for all my other stuff.

A quick Amazon search found USB-C cables or adapters for Apple Magsafe and various barrel ports, so with a little digging you should be able to find options for many older portable models. Just make sure you have a charger that can meet or turn on the electrical input of your original charger.
