What's the best wireless charger for travel?

Travel buyers tend to converge on foldable 25W Qi2.2 stations (Anker Prime, Amazon Basics 3-in-1) or compact 2-in-1s like the Twelve South Butterfly, which Pack Hacker and MacRumors forums praise for folding to roughly the size of a pocket watch. Magnetic 10,000mAh power banks like the Anker MagGo are the alternative if you need topping-up on the move rather than overnight charging.
