Best House Battery direct power outlet Mod

[matter]

Hi all,


After googling around much, I decided to hook up something like this but am having trouble finding a heavy duty one, say capable of 50 amp total output.

Anyone else have ideas?

Thanks in advance.

Thanks in advance.

What would you be plugging in that draws 50 amp? That is a lot of power to run through a USB connection. For example plugging in two laptops and running them hard would draw less than 10 amps actually closer to five.

50 amps takes some serious wire gauge. Pending on the wire length might need a 6 awg or larger diameter wire. Heavy stuff.

What are you thinking about running on this port?

Normally, when you get into this kind of power pull you need a different style connection. AUX ports just do not have the required contact surface area to draw this much power through it.

Maybe 50 amp is a little hefty, but was thinkin' about plugging in a hefty portable inverter into the cigarette part so I could run whatever I want.


The 2019 Redhawk has no real inverter to plug in a 110 anything near as I can tell by look at manuals and googling.

Someone on a different thread told me, “
If you plan on plugging an inverter into it, may want to find something rated a little higher, that is only a 10A outlet.

A 400W inverter, will give you about 3.3A of 120v AC power - but they typically have a 40A fuse in them for the 12V DC connection. 400W is 33.3A for 12V DC. “

+1.

I've only seen cigarette lighter outlets rated for 10 amps DC. A 500w inverter will pull about 46 amps of DC current in order to make 4 amps of AC current (including efficiency loss, etc.)

Watts = volts x amps
500w = 120v x 4.1a
500w = 12v x 46a

I purchased this inverter.

It comes with two separate sets of connectors: a cigarette lighter plug and heftier connector with alligator clips for directly attaching to a battery. The instructions state that the cigarette lighter plug is only good up to 150w. One must use the alligator clips (or some other method of higher current capacity connection) to get up to 500w. I wired it directly to the battery using a 10-gauge 2-prong SAE port.

Max current on 10-gauge wire is 30 amps, so I adjusted the fuse on that port connection to the battery to 30 amps (https://www.amazon.com/10-Gauge-Fuse.../dp/B08BWRSPY1) and limit my load. If I need more than 30 amps, I'll up the port and wire to 8 gauge.


I plug the inverter into the port on the basement wall when I need it and store it away when I don't need it.


If you want USB charging capability and inverter capability, consider making two separate connections. Add a cigarette lighter outlet that you can stuff a USB cigarette lighter adapter into. That way, you're going directly from DC to DC to charge your USB devices rather than running it through an inverter. Plus, you can buy the USB cigarette lighter adapter that is best suited for your device (fast charge, USB-C, etc.) rather than being stuck with whatever the fixed USB ports will give you (as in your image). Then, install a second port rated for the inverter you want to use to power AC devices. To safely pull 40 to 50 amps DC through a connector (rather than just a straight wire connection to the battery), you're looking at connectors like these:
