Hi Guys,

Is it possible to work out how much power these electrical items use per hour?

They (the manufacturer) need to tell you what the motor consumes in either watts or amps. It should be on the label but I can't see anything.

Thanks Spruce

I found this out about the charger

Specification
Watts   96 Watts
Input Voltage   230~240V AC 50Hz via UK 13A plug
Output Voltage & Current   For 12V DC batteries
Dimensions   190mm L x 92mm W x 55mm H
Weight (kg)   1.180
Current Output   8A DC

And this about the pump

POWER: Safe operation with low energy (24 watts), low voltage (12-24V) motors. Can be used with compatible transformers (100VAC, 120VAC, 230VAC), to be ordered separately.

Does that help?

No, it doesn't with regard to the pump. You need to know what wattage the 12v motor is and what wattage the 24v motor is. If the 24 watts you mention is for the 24v then the motor draws 1amp. If the 24 watts is for the 12v motor then the motor draws 2 amps.

With regard to the charger, if I read this right then 96 watts is what the charger draws whilst it's output is 8 amps at 12vdc.  96 watts is just less than half an amp at 230 volts. Seems ok to me.

Are you wanting to use your battery charger as a transformer to run your pump?

Thanks again Spruce,

No nothing technical like that, just a little experiment to work out how much my RO unit, heaters and stuff cost me to run per year.

Too much time on my hands!
