Now, can anyone recommend a small, lightweight PD charger that ideally also has 3 to 4 "normal" USB ports, provides 100 Watts and has an EU socket connector? I would love to carry a single power supply for charging all my devices when travelling.
Anker PowerPort Adam PD4 100w [1] is likely the closest. It has two USB-C PD and two USB Type A. It splits that 100w amongst attached devices, giving the full 100w to a single USB-C PD port (20V @ 5A) or sharing the 100w across multiple devices, for example:
Or the simpler everyday use: 15in Macbook Pro (87w) + USB-A (12w). It uses a standard IEC-320-C7 cable for power (two pin, round hole) so getting local cables anywhere should be easy.
MSRP is $99.99. Availability is a tight, but it does exist. A few sites have reviewed it and there's at least one teardown on the web.
I didn't like a review saying it's small because some components were left in the cable and hence not all USB-C cables work. It might be an outlier/mistake, but yeah...
