Does this need to be plugged in while jump starting and/or trickle charging a battery?

Hi Jen, We have only used it plugged in. My husband thinks you can charge it and use it while charged. I will tell you it has saved us a towing expense on 3 occasions. Twice with a dead battery. So dead....it wouldn't charge. Once a bad alternator. We used the quick charge function and it worked like a charm so that we could get it to the shop. Good luck.

Yes. It appears that the unit require to be connected to a 110 outlet during use.

I gave this as a gift for Christmas so I really don't know anything about it.

No need to charge the battery first if you have it plugged in. There is a form without the battery, in fact.

Yes you can but not advised. It will go down to a trickle charge when batteries are fully charged. ok

Sometimes the battery can be so dead that a jumpstarter does not have enough juice to turn it over. What you can do is just leave it connected for about 15-30 minutes and it will act as a recharger. This will then charge the battery enough to start the car. (Leave it connected as you start the car)

The manual says that it will not overcharge a battery, but I do not know if it cuts off and then comes back on if the battery charge drops.I am not sure if it can be used specifically as a trickle charger.

A good question; however there is no definitive answer since there are so many variables. Myself, I always put a new battery on trickle charge before installing it. I use this particular battery for my security gate. They both showed acceptable levels when they arrived; however once under a load it becomes a different matter; thus the trickle charge fully charge them. Just my way to make sure the battery is fully charged before I install them.

I bought a trickle charger that automatically shuts off when fully charged so as not to overheat the battery. I never paid attention to how long it takes, but would recommend investing in such a charger to save the battery. The charger can be used for other batteries as well.

no, plugs into your lighter port. unless your lighter port does not stay on if your is not running.

Yes. As long as you are jump starting it with a battery in your car and near a power outlet to plug this in.

It won't hurt it to leave it plugged in, I believe It's AGM type battery, the circuit board is design to the battery specification, so yes it trickle charges the internal battery, without the need to unplug it.

I don't use a trickle charger, just start it up more frequently in cold weather until charge light goes off. Usually about 5 -10 minutes. Haven't had it not start yet but strained a few times

I don't think you should leave it plugged in. I charge it for an hour before a planned use but when I simply grabbed it and ran, it had enough juice to start an 8 cylinder jeep.

hi aaron it's a trickle charger only, you can't run anything, like light's, it's best that if you have a disconnect switch to turn it off. this is for maintaining the battery when not in use, works great for that!!!

I've never heard such a question. This is a battery charger, therefore you need a battery. A starter would trip the built in fuse as the draw would be greater than 100 amp.Please rephrase your question. IE: Will this unit charge a low battery to start a vehicle engine! The answer would be yes unless the battery is defective

It is not recommended to run it while plugged in. Like most rechargeable products, it it intended to run from only the battery. Properly charge up the battery before use, let it discharge and then recharge.

I have used it on a battery that wouldn't even turn the engine by leaving it connected for about an hour and then the car started no problem. I do believe it will act like a charger in a situation like that till you have used all the stored energy. I don't think you can use it like a trickle charger though, its not a battery tender.

When the battery is fully charged it automatically switches to "trickle" mode to keep the battery topped up until you disconnect it.
