Does this product perform both functions meaning charging the battery when needed and also as a jump starte

This is a 12V battery about 1/3 the size of most car batteries in an easy-to-carry case. When you first connect it up via the jumper cables, a fair amount of power will be "shared" between batteries (which I think of like having 2 buckets of water where you connect them and the water level balances out depending on how much each had and the sizes). Although that can provide a fair "charge" pretty fast (which may be enough to get a car started), it is very limited and will never "recharge" the other battery 100%. If you have this connected to another battery and plug in its AC charger, power will go to both batteries, but the chargers in these only put out 0.5 amps where it can take 24 hours just to charge itself if heavily drained so it can take several days to charge itself and a drained car battery connected up together. So that's probably why most manuals say "disconnect everything while charging" discouraging doing that, but it can work (if you don't mind the time it takes). Otherwise if you want to be able to charge a car battery in less than a day, you'll want a 5-10 amp car charger.

Hello AlexisIn answer to your question about performing battery charging, and jump starting the answer is yes to both. I personally have used both functions with this charger. I inadvertently closed my seatbelt in driver's door which completely drained the battery. I used this charger for approximately two hours to recharge my battery which it did. After the charge I had no other problem starting, or operating the vehicle's devices. I have also jump started vehicles with this charger. It performed both functions. It also has a compressor to air up your tires.

IIRC it does, the jump starting option draws a lot of power. I'll check mine when I'm in the garage and if it's different I'll let you know.

It will charge when ignition i so, and will takes more than 24 hrs running vehcile to fill completely discharged unit. So, that works, but slowly.Always better to take the devie at home periodcally and charge there.

It will charge a dead car battery with in 13 hours depending on the battery's capacity. It will not jump start a car though.

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.

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

No. It isn't a charger, it is a jump starter which means that it is just another battery used to temporarily "boost" the battery in the car that is weak. While this jump starter has a built-in charger for it's own battery, it cannot be used to charge your car battery--the selector switch/dial can either be set to "jump" (on) your car battery or "charge" (off) to charge itself, it will not allow the charger to function while the jump battery is connected to your car battery.

No this product is only for monitoring battery performance and drains. It can tell you if your battery is running down and if you have parasitic drains that require attendance. But it does not charge your battery. I hope this helps!

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.

This battery pack could be used as the "source" for some "jump-start" devices that use the lighter outlet for connecting the cars together. However I'll add a few comments about using those lighter connected "jump-start" devices. First, several such devices like the Wagan Jumper item 9796 will draw more power than they deliver to "pump" the power, thus they waste some of the energy being transfered. Also they only work if you have a good battery in the car that accidentally got drained, so if the car battery won't hold enough of a charge to start the car, you'll never get going from the "trickle charge" they provide. Those also can take 15-30 minutes to give you enough charge to start, so don't be expecting to plug it in and 30 seconds later to be turning the key to start. Speaking of the key, you also need to have the key in the "accessories" position while charging the car so the lighter is connected to the battery in the car, but you're not draining power with the cars engine computer running like while in the "on" position. So with all of those issues, most don't like those lighter "jump-start" devices (look at the reviews of such), but that doesn't mean they don't work for some.

As it runs, it charges the battery as an automotive engine would. However, I bought an inexpensive "float" charger that I keep in the battery at all times. Do not confuse with "trickle" charger, which can harm the battery. The "float" charger keeps the batter charged, and shuts off when it's no longer needed. The "trickle" constantly charges, and overcharges the battery. They're about $5.00 at Harbor Freight. Hope this helps.

I bought this charger to allow me to jump start my diesel pickup. While I have not had to jump start my pickup, I have used it to jump start both my tractor and my wife's car. It had plenty of power for both these jump starts.

yes it will charge both. also it has 125 amp starting capability and automatic shut off when the battery is charged for safety. it is the finest small charger that I have ever owned. I have 2 and one is 20yrs old and still functions.

Don't know for sure. I think it would. Regarding recharging, rumor has it that it will jump start multiple times before needing recharging.

No. This will not work as a starter. It will only work to maintain the battery levels.
