Wireless is super convenient but I hate all the micromanaging that needs to be done with batteries. Lithium batteries has made this generally better but there's still a lot of subtle ways that batteries like to change when you aren't looking. It's fine when you only have 1-3 batteries to deal with but it gets tedious quick as you end up with more and more batteries.
I am sick of everything having a wall-wart transformer, especially where the size or shape prevents other things from being plugged into the adjacent sockets.
Powersquids are a life saver. I try to make sure I always have a couple in reserve in case I need one.
I didn't think you could get those here in the UK, but it looks like you can! https://www.philips.co.uk/c-p/SPR5500_05/powersquid-5-outlets
My only gripe is that they look a bit messy... I am a neat freak when it comes to cabling.
