12v TV and Soundbar when on standby

[Jewellbags]

When off grid I’m a little obsessive about battery drainage . Does a avtex 12 v TV and sound bar drain much on standby ? As the 12v socket is tucked up behind a cupboard and difficult to reach . In addition I keep my mifi charged and the stereo header unit continues to draw - comments welcome …

What battery (Batteries) have you got?

 

[Figaro]

Can you not fit an isolation switch for the tv and sound bar ?
I guess you'll need the mifi connected permanently but the stereo could do with being isolated too ?

I’ve read somewhere that stuff on standby can use up to 70% of the units power usage….

I have a similar set up and have found leaving them on stand by has very little effect on my power consumption.I bought a split 12V power cable ftom avtex which means 1 plug supplies both the TV and soundbar. Does not effect power consumption of course but does make it easier to isolate both items.

Our TV and soundbar are both turned off at source when not in use.

Same here. The sound bat itself has an on/off button.

Example

24-inch TV

19.8W in use

0.8W standby

That's the battery voltage just after, or during charging, if the battery is fully charged.
In other words, that's the charger voltage.
An hour off charge or a light load will drop it to around 12.6v

That is your battery voltage, if you have solar or on mains it will be the charger voltage.

So no watch the devices are drawing but how much they are receiving ?
