Is it safe to run a battery tender through the DC power port?

An ejection port like on fire trucks would be cool. Turn the ignition and the cord gets popped out of the recepticle!
I thought about it but it was too big to fit on that spot with any sort of mounting. I've replaced them several times on the fire trucks at the VFD. They are easy to install, just takes a trigger wire to the starter to trip the ejection.
 
Absolutely! Zero argument!

My concern is the parallel conductors. All the wires that run next to that wire. The fuse box. The PDC. Possibly the PCM.

I've gone through a lot of battery tenders. I've got mowers, tractors, vehicles, motorcycles... they're all mostly cheap crap.

When one of those fuckers decides to go...I'd prefer it melt a cable that runs from the charger straight to the battery (routed to avoid collateral damage) than taking out half my dash or lighting the Jeep (and my shop) on fire.

All complete long shots. Am I paranoid? Absolutely. Have a hauled dozens and dozens of burned vehicles out of the woods...yes.

So what you're saying is you've seen tenders fail and basically short out the battery and burn up whatever wiring is connecting the two?
 
Weather finally got dry enough to put the Harley behind the TJ, that means it will sit 'most' of the time now as the wife will drive the JKUR.
That said, I have a tender for the bike, but I'm planning to connect it to the TJ after the position swap.
My biggest fear is that the wife will decide to take the TJ and back out of the garage with the cord attached - if I run a typical SAE plug direct to the battery - unless I leave the hood propped open.
I have an SAE-to-cig lighter adapter, so I think I'll take a lesson from the image above and drop the power down from the ceiling through the driver's side door.

My guess is that placing the unit where it cannot be seen regularly is a major factor in the fire count referenced by others. I'd expect the thing to melt, smoke, etc. before it suddenly bursts into flame.
Adding a fuse between the charger and the battery won't do anything to protect the garage/AC side of the circuit when/if the thing goes south... that's what the circuit breaker is there for.

And yes I feel dumb for not noticing it is literally in your profile pic. My excuse is it's little on mobile
