Hamayun Tariq - planning mass murder : given bail
Tommy Robinson - speaking out : banged up in jail

[plain talk]

"Tariq, who used the alias 'Abu Muslim', evaded the UK authorities twice to travel abroad where he is believed to have helped create bombs that could be disguised as laptop batteries and taken on planes. The move is believed to have then prompted the US to ban laptops in aircraft cabins on flights from the Middle East last year. The ban has since been lifted, but passengers are still asked to switch on laptops to prove they have not been tampered with."

If they can disguise a bomb as a laptop battery then they can disguise one as a laptop AC power converter. I have never been asked to plug in a power converter to show that it works and it would take time to test them.
