A few commonalities to the models we focused on: Most of these use a new material called gallium nitride, or GaN, that enables high-power adapters to be made in much smaller sizes. This list goes way beyond a simple phone charger. I spent a few weeks testing some of them and I've found some go-to choices for fast charging on the go. The key is getting one of the latest and greatest USB-C power delivery chargers. The fact of the matter is that if you're packing the right kind of charging cable (or dongles), and your laptop or device was released in the past couple of years, you'll be in very good shape. OK, that's a bit of an exaggeration - but not much. That's because the vast majority of modern devices - including newer laptops - can be charged with a one-size-fits-all USB-C charging technology: USB-C power delivery or USB-C PD.

Thankfully, you don't need a separate wall charger or outlet or cable for each device. Many people own far too many devices to be carrying around a separate cable and charger for each one.

And having a separate charger for each one can be frustrating and frankly a waste of space. From your phone and tablet to wireless headphones and laptop, all gadgets have their own rechargeable batteries.
