|In the uk standard voltage is 230volts - thanks to the EEC/Brussel beurocrats. it "used" to be 240.|
There is a "margib of error" allowed, aka a tolerance; and at peak times the volts may drop slightlly (as per EEC dictat). There are those who want to drop the standard volts even further (allegedly in the name of energy conservation and climate change...)
I would be inclined to have a look at the ac outlet itself. Check that its connections are secure; the screw terminals have been known to become less than secure over time. Similarly the actual pin connectors - the actual contacts for each plug pin - are not worn etc. these too have been found to fail over time.
Also is the charger directly into the ac socket, rathan via multi-p,ug adapter or extension bar?
Have you tested using another ac outlet?
And have you tested connecting the charger directly to the ac outlet - no voltage stabiliser involved in its path?
If you decide to inspect ac outlet connections - remember to switch of its circuit breaker, or remove its fuse (if your consumer unit uses those). leave a warning note on the consumer unit advising "everyone" that that circuit breaker is off and not to reset it - unless "you" say to.
Also - before removing ac outlet itself - confirm the socket is dead; use a Martindale or similar socket tester, or a working portable mains powered lamp (a table lamp will do).
You can also double check the wiring of the outlet using the Martindale, although it may not show intermittent/poor connections clearly; but if it does not show stable indicators - and they "must" be stable - it would point to a possible problem with outlet, or even the actual mains feed/cct. to the ac socket.
