Bought it here It's off ebay but UK supplier despatched from UK .
My first thought was to do what you said actually until I realised when I looked that a lot of stuff ,including another charger I have ,has the these converters fitted and I had one spare . Yeah it should have had the thing...
It's a car type 3 stage charger . I'm putting the attached 2 pin plug into the 3 pin for use here in the UK. to use manual says to be connected to 240V 50Hz . The 3 pin plug is the type that opens up and you place the 2 pin one inside locating the pins in the live and neutral positions .
I have a battery charger with a European 2 pin plug fitted . I have just noticed that the three pin plugs on other appliances I have are actually adaptors which accept the two pin ones inside and the pins locate in the live and neutral terminals .
How do I identify the positive and negative...
