Its kind of annoying for tjhe time being as you don't know until on board if you have NCW or NGCW- both of which require completely different sets of leads.
Empower was good- I have a travel one which has car type one (like AA have) and an empower which goes onto that.

Maybe they have used a US plug as it is a lower voltage. Then they cant be blamed when stupid people blow up their 110v gear by plugging it into a 220/240 socket with no transformer- only a socket adaptor (just like the ex GF- American- did in Barcelona with her hair drier despite me warning her it needed a transformer...)

p.s- not implying that Americans are stupid...just using her stupidity as an example. ......
