I can’t agree more. I have used Targus adapters in the past, but long time ago I settled on the Juice 70 (the second link). It is really good and solid, but the AC cable a little thick though.
Only one problem so far… In Lufthansa’s seats, with 110V sockets, the charger draws too much startup power (just a peak) triggering sometimes the seat protection and shuttting off power.
Everywhere else it has worked great.
