The BBC account says very little but the new deckers do have WiFi and both 230v and USB charge outlets on the bus I have noticed so it could have been in use.
As to wave form of 230v outlet or power available both from 230v and 5v USB I have no idea.
In my own car I use an inverter and phone charger plugged into that just never got around to buying a car charger.
A related story How dangerous are phone chargers? claims Charity Electrical Safety First recently commissioned tests looking at the safety of chargers bought from online trading and auction sites.
It found that half had been wired using "sub-standard components" and none met with the safety requirements of the Electrical Equipment (Safety) Regulations Act 1994.
I wonder how many of the official chargers meet regulations? I have a official Nokia charger with an extend-able earth pin which I am sure does not comply and also official 230 to USB Iphone charger again where the area covered by the plug base does not comply but this does not make them dangerous.
The report "He said he saw a white flash and a flame about 50cm (19in) high, which caused the girl to drop the charger to the floor." makes one think it was not plugged in.
The Wales Online reports "The 14-year-old girl had just plugged a newly bought battery-powered charger into her touch-screen mobile phone when it exploded, sending a two-foot ball of white flame into the air." So maybe it was not plugged in and this is yet another NiMh battery explosion just like Dell computers and Boeing aircraft.
Maybe we should return to using NiCad batteries? But I had thought the battery problem what when they were re-charged not when being discharged? Any thoughts please.
