I recommend the dual-port 60W Anker: https://www.anker.com/products/variant/powerport-atom-pd-2/A2029121 https://www.anker.com/products/variant/powerport-atom-pd-2/A... It'll do 60W from one (laptop), or 2x30W and is fairly compact. So I amusingly now have lightning to USB (damn you Apple), and also bring a single USB-A to USB-C adapter sometimes (e.g., for a Fitbit charging cable).
