Does this product drain power from the battery when no devices are attach I would like to connect to a port that is only active when the engine is on.

Not noticeably for a couple of hours, for example leaving a cooler plugged in while you go for a walk in the country park, but I wouldn't leave it on for long periods without the engine running.

This product comes with a cord with clips on it so you could connect it directly to the battery. The product then would produce to it's maximum stated power output. In any case without anything plugged in to either the AC or the four USB ports it would not drain enough power to have any impact on the vehicle.

I have experienced no battery drain issues. I almost always turn it off when not in use as a precautionary measure. It has been on no longer than 24 to 48 hours without cranking a vehicle. Like I said earlier , I have never had any issues. It seems to use minimal power.

No, not unless your cigarette or power port is only powered with the engine running. But it's a moot point because a large power unit such as this needs to be wired directly to the battery. It can draw way more power that the fuse or wiring of a power port can handle.

if for some reason you lose one or both batteries this port can be used for wired charging and sound. also, it can be used for forcing a driver update but this method is never needed as if it has power it has a connection.

Robert the device plugs into your 12 volt adapter or cigarette lighter ...so there is always voltage there after you turn the car off I pull mine out a little so it does not make a connection that's the only way to disconnect from your battery. but there's no problem. I would highly recommend this product I love mine it is totally hands off thru your car speakers. Just like onstar

Does your car charger port shut off if you turned off the engine and remove the key? If it is the camera should turned off with in the time you set it up. And if the car port don't turn off after shutting off the engine you're going to do it manually. Hope this help.

Garry - i'm not 100% positive (like 75%), but pretty sure that the OBDII comm shuts down shortly after most cars are turned off & I believe that this device (powered by OBDii) will also shut-off and thus not drain the battery.

Depends on how you want it wires. I connected mine to the stock wiring behind the cigarette lighter. That way when the key is in the acc or vehicle on position (engine running) the monitor will always have power. When the vehicle is off the monitor loses power not draining the battery

Yes, I have mine attached to my battery in my boat 24/7 (at least in the summer) and use the boat at the same time. Don't expect this charger to come anywhere close to charging your battery while using the trolling motor tho. Connect it and forget it.

Yes, connect to a cig lighter outlet that doesn't stay on after the engine is shut off and the unit shuts off on it's own. Comes back live when engine/car is turned on.

I don't think there's any battery drain, but I can't say for sure because mine is only unplugged when I'm using the boat.

I'm not sure what you mean. If you're asking if it will still work without the car being either on or on accessory, every car I've ever been in does maintain power to the cigarette outlet even when the car is completely off. If that doesn't work, just turn your car on accessory and it will work fine. You just turn the switch on the invertor on. I'd recommend turning the interior lights off in your car while doing this or run the cord through the window to prevent running the battery dead. If you do that, you won't have a problem with your battery going dead, not even close.

It depends on your car. Some cars continue to power the outlet even when the car is not running, and some cars turn the outlets off when the car is not turned on. Even if your car has the type of outlets that continue to run, this will not cause a significant drain on your battery.

Only if your power outlet only works when you have the key in the on or power position. Most cars do have a power outlet that works without the engine on.

As long as a device is not actively pulling electricity through the port, then there should be no strain on your battery. Your lights drain your battery because the device is engaged and actively pulling a charge through its circuits. The only issue I have had with leaving the device on is that even when my car is in the garage, my phone still passes the calls through it. Makes for an awkward first 15 seconds of a conversation....

Oh, whoops. I used mine while the engine was running with no problems. My 12-volt ports aren't powered unless my car is at least in accessory mode.If you're really afraid of your battery dying, you're probably ok using it with your car on. Just wait until your car is started before plugging it in (to prevent a surge) and make sure your parking brake is engaged.

Does not drain my battery & I do not have to have my truck running. Sometimes I may have 2 or 3 devices plugged in.
