The biggest issue you're going to run into is that most multi-port USB-C PD bricks won't put out full output when more than one port is in use. I wish the manufacturers would come up with one which did. The larger wattage chargers also get exponentially heavier. If you're concerned with weight, you're better off going with two smaller chargers than one to rule them all. This also gives you some redundancy, which isn't a bad thing on the road.
I'm currently using these:
(Nekteck 65W USB C Charger GaN II with 6.6ft Cable). At $25, including cable, you can't go too wrong with these. Folding prongs. Compact. Pretty light-weight too. Single USB-C port.
(UGREEN RG 65W USB C Charger, Nexode 3-Port Robot GaN Fast Charger Block) Feels a bit better built than the Nekteck. It is shaped like a robot with a cute LED "face" that indicates the status... Power / Connected / Charging. It lacks folding prongs, but comes with magnetic "feet" to cover the prongs. Has 2x USB-C, 1x USB-A. Like all of the multi-ports, plugging in multiple devices will reduce the amount of power it puts out.
(Anker USB C 120W, 547 Charger, PowerPort III 4-Port Charging Station). This thing weighs 500g / 1 LB! Once you get past that, it will deliver 2x 65W USB-C connections simultaneously. Or 1x 90W + 1x 20W, or 1x 60W, 1x 30W, 1x20W, or 1x 50W, 30W, 20W, 20W. It does have a cord, which I find to be a plus when traveling. Other than it won't deliver full power with multiple devices connected and weighs a ton, I have no qualms about it. It is nice to be able to plug in my mobile phone and computer and not have the computer complain about reduced power.
(Anker 511 USB Travel Power Strip, 2 Outlets & 3USB Ports, 5ft Soft Extension Cord 30W) Think of this as a power strip with built in 30w charger. 2x USB-A ports, 1x USB-C, 2x 110v/240v outlets. The unique feature here is the ultra-soft, ultra-flexible cord. It's as flexible as a soft rope. I use this constantly when I travel, with the laptop bricks plugged into it. Then have the best of both worlds -- the bricks can run full power and I let this guy charge my mobile phone
Cables:
(INIU USB C to USB C Cable, (6ft, 2-Pack) 100W). So far these haven't let me down. Braided cable, slim metal ends, and one of the ends has an LED which lights up when connected to let you know there's power flowing. Unfortunately due to the limitations of USB-C, BOTH ends of the cable have to be connected for the LED to illuminate. They sell some USB-A to USB-C cables wherein the USB-C connector is illuminated 24/7 which makes it great for finding the end of the cable.
So, no ideal solutions on the market yet, but these are the best I've been able to come up with for travel. There are some desktop USB-C charger stations which do have higher outputs, but are too large and too heavy for travel. Perhaps in the future we'll see it.
