What equipment can you use with in-seat power? Can you charge and ipad or laptop and if so, are both US and UK type plugs accommodated?
You are not supposed to charge any device on any A/C with in-seat power. It only supposed to be used to power your device whilst you are using it.
The socket type will depend on the A/C.
All the aircraft with VERA Touch (all the A333's plus the LGW/MAN 744's) have dual UK/US standard sockets.
Aircraft with VERA on demand (what was V:Port) i.e. all the LHR A346's and LHR 744's have an Empower socket so these need a special cable/adapter.
I think the A343's with VERA Reel have no power sockets at all.
