I bought this to replace the 65W-class Mopoint travel charger that started acting up for me with a crackling/sparking sound that seemed unsafe. Like the Mopoint it comes with interchangeable plugs for EU and UK, but an AU adapter is missing. The Mopoint adapters *do* fit to this Syncwire 67W charger, but attach less satisfyingly, with more of a friction fit.Dimensions are 58x58x30mm, which is larger than the Mopoint 66W or Aukey B4, but then again it doesn't spark. Of the three adapters the Aukey B4 is the smallest but doesn't have snap-in-place plug converters and therefore isn't very useful for international travel.Both the Sycwire 67W and the Aukey B4 keep the C2 port powered without interruption even when a device is plugged into the C1 port. This is not the case the other way round (C1 will temporarily lose power when a device is plugged into C2) but allows operation of e.g. a wireless travel router on the C2 port. The Mopoint will interrupt power to all ports when "rebalancing" its output.Overall I'm happy so far and will update this review if something should change.
