I have two of the predecessor to this, 45W / 30W / 18W +15W - this successor is 45W / 30W / 20W +15W , and it works to charge my newest laptop which maximum needs are 45W but is happy to get 30W or less if I use the 2nd USBC port.
Note all of these “desk” chargers use C8 cords, they come with the cord with the local plug type but you can use other country type cords and/or plug adapters. e.g. last week I visited USA and swapped the UK delivered cord with a US cord and spent a few nights in UK with US-UK plug adapter on end to minimise total tech volume/weight.
Pretty good value when you look at the newest range
