My Old one had the 3 plugs you slot on. But I didn't like having to swap them out. And I use it at home. I know what I'm like. I could. Easily forget to bring it!I use a desktop multiport charger that has a figure of 8 mains lead socket, I then just take the correct lead with me and have it sit on a table for everyone to use.
I got this one earlier in the year as needed 65W for my Dell laptop, was £70 at the time, but have found the cheaper chargers are always a bit fast and loose in their descriptions quality.
Things like saying "65W!" but then you read into it more and it's 65W maximum across 7 different ports
