Hello,
I have a vacuum cleaner which works with batteries and I use it for cleaning inside my car. The problem is that the yield is too short only around 10 minutes with fully charged batteries.
Now I would want to connect a plug for the 12Vdc car´s connector and use this source as power supply. I have checked the power when my car is running at this plug and there are 14,4Vdc.
I aslo checked that the vacuum cleaner uses a motor which consumps 7A at 3,6Vdc (3 batteries in serial) so I have thought about the possibility of installing a power transistor which takes the 10,8Vdc at its Vce or Vds. I think is necessary to use a MOS transistor but I don´t work usually with them so I´m not sure if that is possible to do.
For example I found a IRFZ44R which I think has enough properties to do it but I would like to confirm the way of connecting it. Can you help me?
Thanks and best regards.
