Does the vehicle have to be running in order for this charger to work?

This is entirely dependent on your vehicle. In some models 12v plugs can remain live when the car is off, and others do not. In example, my Grand Cherokee has two live ports at all times, and one that turns on and off with the engine. My girlfriend's Hyundai has zero live ports when the car is off. The quickest way to tell, plug something in with the car off and if a led light comes on it is a live port. As a warning, 24/7 live ports will slowly drain your battery if you have a draw on them when the car is off so unplug your charger when not in use.

I think it depends on the car really whether juice is supplied while engine is off.

Mine burnt up while it was in use, and the car wasn't on. Had to get a different one. It works great, when the car is on or not.

It comes with a 12V car adapater and it needs to be plugged in all the time. There is no 'charger' as such because the device doesn't have a battery and cannot run under its own power. It needs to be connected to the car power supply at all times.

Yes You have. That is why the pigtail so you don't have to disconnect the batter from the vehicle, just plug it in and it will maintain the charge, but You must un plug the tender before starting the vehicle

NO. Though it is a small trickle charger, it is only a maintainer for an almost fully charged battery! It a great maintainer to leave hookup to a good battery.

As in "If your car battery gets low will this shut down?" If that's what you mean then no, it doesn't. If the device doesn't receive the charge it needs to run, however, it will shut down. Your car battery won't drain with this turned on as long as your engine's running, thus, keeping your car's battery charged.

The battery is sufficiently charged when installed. When you start the car, the battery should charge normally. I have had no problems with the battery.

Your car, not the wall unit, decides when to initiate charging. At least that is how it works with my Nissan Leaf and the GE WattStation. If the timer is off, it will start charging immediately upon plug in. If the timer is on, it will follow the timer's instruction.

I have never seen a charger that needs a relay. As long as they are attached + to + and - to -, all you should have to do is plug the charger in and let it do its job. Of course, make sure the connections span the entire bank of batteries. If you have questions how to do that, l suggest you have someone familiar with connecting batteries in series look at the wiring before you plug it in.

It will drain a battery,that is why the engine has to be running.That is what I understand.

the car charger is not intended to run your laptop its intended to charge your laptop the lap top runs off the battery and the charger uses a converter to charge it!

the battery has to be disconnected from whatever the battery is powering, otherwise you charge not only the battery but also the connected car/RV etc. This can be harmful to your cars electronic or the charger itself. I sell these chargers (6 volt version) with my battery powered pet fountains and had no complain over many years.

Yes it is. In fact no matter what type of vehicle even if like me you have upgraded to multiple AGM batteries this charger will work for you. It is simple to use (one button operation) and the microprocessor inside the charger ensures you don't overcharge your battery(s) even if its hooked up for months at a time.

You need to charge it first. By the way, it is a trickle charger. It will take a while to get up enough charge to start the car. It does not fully charge.

As far as I know this charger is not smart. As long as it is plugged in, it is on.

The car charger has to be plugged into the cigarette lighter slot of your car. Once it is plugged in and you have connected the phone to that cord your phone should start charging while the engine is running. Of course you know that the car charger is only going to charge the phone and not the car, right? Juar kidding you.

NO, it must run on battery, but don't underestimate the battery run time, I have a really small lawn, but I remember I only charger couple time for the last season.

The only way I know to charge this is to plug it into a 120 volt line. But I can tell you that it has worked when other smaller chargers would not start an engine. The other day I helped out a workman whose truck battery would not start, and the small unit he had would not turn the engine fast enough, or supply the amperage for the system. I hooked this monster up and the truck started in one second.
