can I take it fully charged on a trip if I need to start my car

Unfortunately, this is not a "jump-start" device, and does not store power. It only converts 120 VAC to 12VDC. You need a 120 VAC outlet in order for it to be of any use.

No. Based on what your saying, with key off cigarette lighter is disconnected from the battery, it must connected to the battery to charge it.

Hello. Once fully charged, as long as it is not used at for any type of charging, it should be able to jumpstart a car for at least 6 months. Thank you.

If your intention is to charge the battery DON"T even try it. Not only can you ruin the battery but you can build up pressure in the battery causing it to rupture and it's full of acid. In order to charge it from your car you would need a current limiting circuit that would shut off when the battery is fully charged and that just isn't practical to build. So just get a regulated trickle charger that does not exceed the amperage limit of the battery.

If you could tell the capacity of your battery then we may compare. I personally found this starter useful even for completely dead battery. In that case, I simply leave starter connected to battery for whole night to transfer some charge to car's battery. Then charge starter again and it always works... Also I noticed that if car has computer on board then you need to pay attention that after successful start there are no errors displayed. Those errors may mean that car will NOT charge battery and even after 100km drive, you will end up with the same dead battery. Wish you safe driving!

Yes, you can. When the unit is fully charged, it cuts off from the charging mechanism. Mine is always plugged in, and ready to go, when needed. Happy screw driving. Does'nt it seem logical? Otherwise, it would be useless when immediately needed. Go for it!!

No. The charger is only necessary if you pound your stereo hard at idle or with the car turned off. Once you take the battery below 12.6-12.8 static voltage from usage then it will need charging. If your plan is to put it up front as your starter battery then your completely fine since your alt charge will be enough to keep topping it off.

Yes. You can play and charge it with household power. It also has a DC power supply for in the car charging and usage.

Yes you can, but my advice is to let your alternator keep it charged. It'll save time and be more efficient for you.

Yes you can as long as the car is running. It will not charge if the ignition is off! it uses no more power than a phone charger and heats up nice, not too hot like some!

Yes. I haven't had it very, but I have used it 3 times so far. Jump started my car, charged my other car battery and used it on my lawn mower battery to charge it as well. So far I love it. Very easy to use.

Well actually onceit is charge enough you're good enough to use it more than a few time you don't have to keep it charge always just make sure you charge hundred percent and your good for at least week !! And it's all depends how you use it!! But believe it or not I drive a tow truck and I sometime I don't even charge for a month and it still has enough boost to start the car !! I hope this answers your question!!!

Of course you can. All that will happen is a red light will be up. The red light means its charging. I do this all the time.

No. All you have to do is charge it for a little while, and you're good to go.

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

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.
