Is this device have enough power to jump start large SUV type car's battery?

I have doubts on this (or similar devices) being that reliable for jump-starting any car with a fully drained battery. The battery in this is about 20% the size/weight of most car batteries, so I don't expect but that much power out of them. Most manuals for these say things like "Don't try cranking the engine over 5 seconds or the battery will be damaged". The reason for that is because it's so small a battery and you're expecting so much power from it that cranking the engine seems like creating a short circuit (which could make the battery explode if kept in that state for over a minute). Although the sales people like to put the "400 amp" labels on these to make it seem big, I doubt you can really get 100 amps for cranking an engine. I've seen a fair number of reviews on units like this saying "It didn't work for me", so feel free to look at those (sometimes the negative reviews give more info than a "Works great" one where that's all they say). Also feel free to see my review of the Peak 1 450 jump starter (and that one has a 18 amp/hour battery, this one is only 5 amp/hour). I'm not trying to make you go after a brand (several brands sell virtually the same thing like Clore, Stanley, Black & Decker and more), but realize it's limitations since it's not a full size car battery.

Not a problem on my 97 explorer v8. 5.0 liter. It has started every time from a dead battery as the vehicle sits most of the time.hope this answer helps

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 think that it would do a great job of keeping your battery at tip top charge and condition. There are several settings that you can use when setting it up for you use. It will even pulse the battery to reduce the amount of sulfation that builds up on the battery plates making your battery operate as nearly new. The capacity for this model is 3.5 amps max, but don't let that confuse you, it operates incrementally and will also show you where the charge level is using LEDs. If there is a power failure the unit retains its settings and can be left connected even when not in use. There are mounting screws provided and two different types of connection configurations; hard wired with lugs (recommended) and clamps that are similar to those on jumper cables, but smaller. You can unplug the lug end that goes to your car battery and plug the clamps wire into the output and it will charge any battery from 6 to 12 volts. this is the best system I have ever used. Enjoy!

No, you need something specifically designed for that. Look under car starting battery or charger

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.

I would not use this to try to start a pickup truck or large car. I've used mine on motorcycle batteries (mostly to recharge not jump start) but I believe it is only a 11-13AH battery whereas most "heavy duty" jumpstarters are greater than 17-20AH strength. I've never had mine tested for CCA but I expect it is nearer to 200 than 400. It is useful for motorcycle carry-along for charging 12V (socket) and 5V (USB) items. If you are looking for a good car backup jump starter I suggest a heavy-duty power dome. The hand crank on this one too is mostly gimic and would take hours even to charge up enough for a dead cell phone if you let the main battery die. I like mine for it is lightweight and fits in my motorcycle luggage and take it on long trips "just in case" of need of an air pump or light recharge. I do not recommend it for a primary jumpstarter for a car or pickup (and yet I've bought 2 over the years).

Sure. The power input is just a cable with cigarette lighter on the car-supply end, and medium size coaxial DC plug on at the device. You could easily cut or remove the cigarette plug and wire to a fused *12 Volt DC * power source in the vehicle

No! It is really an extension of the cigarette lighter socket, the wires are not heavy duty to jump start.

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.

I don't think anything that would have a plug on it would be heavy enough wire to jump a dead battery. If you meant to charge the battery so it will start (not have to hook it up and jump immediately without allowing other dead battery to charge) you might find one with two male ends or you could easily make one by cutting two inexpensive ones wires and making sure you align the positive wire (the one going to the middle pin on the male plug) to be positive. Keep in mind if you accidentally brush anything grounded in the care with that protruding point it could spart or short the fuse that often is in the male end or your fuse panel that is connected to your access point in either vehicle. Plugging it in like that would also require both power points in both vehicles to be on-so if it is not live when the key is not switched on it won't charge. The wires in these alligator clips is unusually heavy and would support higher voltage draw you might get with a totally dead battery on the other end. But if your wires in the vehicle are not sized that heavy you could risk fire or blow the fuse. A dead battery will draw heavily when first attached, especially if you activate the starter to try to start it, it could melt your wires or blow the fuse then. Good luck-

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.

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.

Absolutely. This jump box has started every vehicle that I have attempted large (Range Rover and tow trucks) to small (Hyundai and motorcycles). I use it 3 to 5 times a day it our towing/roadside service business. Best!

I would think. I use it to jump my motor home which is stored. This has a lot of power and jumped a dead battery instantly.

yes. It works fine just get a big car battery and a case for the batrey you are good to go.

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.
