For travel (airplane) chargers for my laptop, I like to get the Apple ones because they have a replaceable 2-prong plug that lets me plug in a longer three-prong cord that sits in the aircraft power outlets a lot better since they're worn (and because most USB-C laptop chargers are heavier than your typical phone brick). The one that my laptop uses is 96W and that trips the breaker every time. I got a 67W charger for about $50, and will use that on aircraft. It will still charge my laptop, just at a slower rate. I can charge my phone off my laptop, or off the charger itself since everything in my bag is USB-C PD capable at this point.
