This is not the lowest price for this product (was £32).
This is a good travel charger where you have a lot of devices and/or where the wall socket is in an inconvient location - e.g. B&B where usually there’s only 1 socket far from the bed.
45W is sufficient for most laptops to be charged if they take USB-C.
Supports PPS for faster charging of Samsung, it may even be the SuperFast 2.0 45W but that’s not been tested but will do 25W.
I have the near-identical predecessor 63W the main difference is the 18W port became 20W.
