Comment(by tonyforster):

 I have a variac, so the charger and laptop are out in the shed on 278V, we
 will see what happens.

 This is only one charger so this may not be significant, I may be just
 unlucky to get a dud charger. However if the Darfon charger is more likely
 to trip out with bad voltage regulation, it will cause a lot of problems
 in the target market.

 Though the distribution code allows +50% for 10 seconds, I doubt that I
 have been getting >260V overnight.

 The problem is more likely to be the crowbar tripping and this would
 probably result from switching transients more than overvoltages.
