I have used a power inverter connected to the battery in our Subaru Forester to run a fan in the house when losing power during hurricane related power loss. Can I do this with our ID.4 and will the large battery charge the smaller one for this? If not, perhaps I'll just sleep in the air conditioned car.

Inverter on 12V bus to power devices during extended...

So, I own a '19 Chevy Bolt. It has a US-made battery so it wasn't under recall until ALL Bolts got recalled on 8/20/21 (General Motors to Recall Additional Bolt EVs). I also had '13 Leafs for almost 8 years. I'm in California and am considering requesting a buyback to see what GM offers for...

Power inverter to charge an ebike-battery ?

Hi i want to put an inverter into the trunk and thinking routing a powercable from the 12v battery to the trunk... The 12v socket doesnt have enough power for this task so i need to find a way for cabeling! and yes i gonna only charge when the car is moving... or u put a weight in the...

This is a bit of an unanswered question right now! Lots of people are asking for different reasons (eg to power a 12V fridge when camping). But I haven't seen an answer. Test is easy to do!

1) Move the fuse so the 12V socket in the back is powered all the time.
2) Measure Voltage across the 12V battery (and continue to measure throughout the test). Voltage should read 12.8V (or thereabouts).
3) Attach a load, ensure it is continuous, a few hundred Watts is perfect.
4) Monitor Voltage.

The voltage could slump a little as soon as the load is applied (depending how big the load is) eg to 12.6V. As power is drawn from the 12V battery and it becomes discharged the DCtoDC converter will hopefully kick in and Voltage would suddenly rise to 13.8 or 14.4V (or something similar). If this happens you know you're good to go and can use your inverter as you describe without exhausting the 12V battery.

An alternative is to force the DCtoDC charger to stay on by keeping the seatbelt connected and putting a weight on the seat.

Short answer, yes. I have a 1000W I connect to the 12V battery. Leave the ignition on and you're good.

Where did you connect the negative cable from your inverter? Battery neg terminal or a vehicle ground?

There is a large aluminum negative post on the firewall directly above the battery. Makes it easy.

Good to know!!

Have you experimented and confirmed that the DCtoDC converter is only activated when the “ignition“ is on? Even if the 12V battery is depleted? Bit annoying if the car would sit there and allow itself to be crippled by a dead 12V battery when it has the means to prevent that sitting there doing nothing…
