iv seen some voltage regulaters in robinsons mall, in their handyman store,

now im not sure what it is i should be buying,
it looks like a transformer or battery charger,
2 voltage meters at the front, at the rear is 3 times 260 volt sockets for multy connection uk phil ect, plus 1 socket for 110 volts, the unit has a 2 pin plug to plug into a 2 pin socket from the main supply,

there are different models and prices depending on how many watts output,

can anyone advise which would be best to buy,

i take it that the more the watts output the more appliances can be run at the same time,
like,, washing machine, refridgerater,,computer ect
