Can you pull 200 watts from 5th Gen 4Runner outlets while driving?

[BlackWorksInc]

The main reason I was wondering is because I don't know what the operating amperage of the vehicle is and the overhead when pulling 400w. It's been years since school, but I vaguely remember them stating it's not great for an alternator to be operating near it's peak for significant amounts of time.

It's something that someone with a little electrical engineering knowledge, time, and a good ammeter could figure out probably. I just don't have a good ammeter or time... or a 5th Gen to experiment with. lol

I'm sure it's fine, but someone had wondered if it would hurt anything/the reason why Toyota didn't just let you do it while driving and while I don't think it would cause issues; I was just trying to figure it out.

I am having a similar issue where my rear 12V port only is giving my Bluetti eb70 35-40W. The AC plug with power supply gives 180W no problem. Any fix for this? I am going to try to use different ports on the 4Runner to see if that makes a difference. I wonder if the two add a fuses i have on the 12V drag that line down? Is there any voltage regulator accessory that can regulate to 12V and let the Bluetti pull the full current?

40W is about what you should expect from a 12V Auxiliary power socket in the rear. There is not a great way around this without modifying the circuit and upgrading the fuse.

You should be charging your bluetti with both AC & DC ports in the back of the 4Runner. 12V to USB-C on your unit and your AC power brick in the 120v. If your AC brick is rated for anything over 100w you will need to replace it with a universal one that is in the 70-100w range.
