Does this work as a jump starter? Does it have an internal battery or does it have to be plugged in to work?

Yes, it has an intermittent high output ("jump") setting. It must be plugged in, no battery.

It has to be plugged in to work, but it works very well on dead batteries as well as keeping batteries charged in vehicles that don't get driven often.

Yes will work as a jump starter. Have to plug it in its nice if you need to slow charge a battery as well. Very well made.

You won't get much benefit plugging it in while jumping, as the onboard charger only charges at a low rate compared to the hundreds of amps the battery puts out during a jump start. I wouldn't bother trying to do that- just use it and then put it back on charge.

You can use this to jump start your vehicle and if the vehicle's battery is still good then letting your engine run for a while (usually 30 to 45 minutes) should charge the battery. If your battery won't hold a charge then its time to replace it. I don't think you will have good results trying to charge a battery directly off of this. This jump starter is basically just a battery itself that you can recharge by plugging into an outlet.

I like to leave it plugged up to maintain the full charge. but this is a good powerful jump box. I used it to start my diesel tractor in 0 degree wheather . I left mine unplugged for about 3 weeks and it still had a full charge in it. this is a way better product than the cheaper jump boxes. it is worth the extra money in my opinion.

Get a jump starter that had the cigarette lighter outlet on the side. My grill came with the plug for that power source.

It is truly a push-button start. It works well. The only problem I have had is when it got down to 10 below, the little battery would not turn it over. I fixed that with a $20 trickle charger. Now the battery stays up and warm. Starts good.

yes you leave it plugged in when not using. I have had 3 of them now thy are great for jumping vehicles. recharges fairly fast.

Only 10 to 15 seconds until the car or truck with the weak battery starts. M power jump is a great product with power to start cars with dead batteries.

It has a pull start but you have to have a start plug it is like a spark plug but it is a battery that you plug in into the car/truck I highly recommend you by the starter kit that is recommended to buy with this gas powered beast I just had mine clocked at 75 mph on my Rd these things are awesome well worth the money but just do your homework because these "toys" require knowledge and work to keep running properly

Please forgive my ignorance Arthur. I purchased this to trickle charge my Optima Batteries. I am not sure if you can jump start, but you would need to have it plugged in. There is no battery in the unit. Very light.

no internal batteries to power the unit. It needs a 12V DC source like the battery that starts the engine.

If you think this is a charger then you may be wrong. It is a jump starter only. If you are referring to charging the unit itself all you need is an extension cord to plug into the back (117 V AC)

It's designed to be used with portable jump starting devices that usually have a cigarette lighter port on them. I've also used mine with a cigarette lighter to battery adapter like this one - http://www.amazon.com/Roadpro-Battery-Clip-On-Cigarette-Lighter/dp/B00065L2D8/ref=sr_1_1?ie=UTF8&qid=1383415417&sr=8-1&keywords=battery+cigarette+lighter+adapter - I've used it with either a motorcycle or car battery sitting on the floor of the car. If you use the battery sitting on the floor of the car method, be sure to triple check the polarity before plugging the cable into the OBD port in the car.

It comes with a plug to put into the cigarette lighter outlet to slow charge the battery, but it's really best to use it to jump start a battery when you need it.

Yes, with a 3000mah battery or greater and in 5-7 second intervals! If starter is held for to long 550 motor will turn inside and twist wiring due to over heating! Hope this helps and have a blast!

I believe there is two models. This one is for jump start only. It comes with wall charger, and that is pretty much it.

It has a re-chargeable battery. If the battery is charged up, then the tool does not need to be plugged in. It does come with an adapter to plug into a cigarette lighter if the battery is dead. All you do is remove the valve stem cap and screw the end of the air pump onto the valve stem and then turn it on to let it air up the tire.
