This is a combined power metre and extension lead
It has a special socket configuration for one larger sized plug
and four normal sockets for normal sized plugs.
But where this extension lead differs from your standard
one is that it contains a power consumption metre.
If you connect this to an inverter you will have an
accurate readout on the LCD screen of exactly how many
Watts you are using through your attached appliances.
This will take the guess work out of adding or trying to convert
Amp hours to Watts because you can see in an instant exactly
how much you are using.
This is the energy measuring extension lead
With this lead you can measure the energy consumption of up to 5 devices at the same time.
The energy meter measures,
It has an integrated rechargeable battery for storage of data incase of power cuts.
The data will calculate the amount of carbon dioxide used and the corresponding energy cost.
The extension cable length is 1.5 M
