Other than jumping a car with a dead battery, what makes this one so much better?, does this one do more than the others on Amazon at a lower Amps vs. 1700?, what does the 1700 amps give you extra? and how does the auto charge work?,

Bigger vehicles like most SUVs require more amps to get them started. Spinning big engines take a lot more Amps. Even with small cars you need a lot of Amps to get them started if the battery is completely drained or if the temperature outside is very low. Also with a good jumper pack you get multiple start ups before you need to recharge it. I had a few smaller jumper packs before these ones and some times i couldn't get the cars started. I also had two other brands of big jumper packs and i had some problems with those too. Right now i have nine of these in my company and i am really happy with them. I intend to buy three more within the next few weeks.

Regardless of what vehicle it's in or if it's running packs in parallel or series I've always stopped at 3.6v/cell when the pack is at rest. You could possibly go lower and still be safe, however I noticed that my packs lasted a lot longer stopping at 3.6v/cell. Also I found these alarms to be rather quiet. Just a heads up.

It seems to me that some of the batteries are "juicier" than others. If anyone knows a trick to bolster the voltage, please be sure to share with me. It's hawks that would benefit in my neighborhood.

As stated below, this one has more amps, the batteries are 3.0 Ah vs 1.5 Ah. Also, this one has more torque.

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!

I would suggest a good battery , I can't say how many amp as I didn't use an amp prob .It is slow but it lifted the driver front on a 1970 Ford Ranchero as a test.

The first answer is no longer relevant. Amazon's info for this item is out of date. The new specs for the unit are 120 watts, and 280 ft. lbs of torque! This is about 10 amps. I say about since there are losses in the line and plug, and because when the car is running the voltage is higher.The new model is awesome. It takes lugs off of my 4x4 in one or two impacts, so less than 3 seconds. Two impacts on the way back on sets them just a little tight, but not so much that it would cause harm. I wouldn't dare let it hit another time!

You can hook direct off battery if that is easier for you, the small amp draw would be no drain on battery. Make sure you have a on/ off switch. It would be recommended to install a fusible link in the live wire, you can buy these links anywhere automotive acc are sold. Just a length of wire wirh a spot to insert say a 15 amp square fuse.

This isNOT a jump starter. It's a maintainer and a darn good one. It puts out a max of 4.3 amps. You need 30 amps to jump start. If you put this unit on your TV all the time you won't need a jumper, and your battery will last a lot longer.

I believe the 15000 Mah would be that much more powerful (able to hold a larger charge). If you watch the videos, this seems to be more than adequate power for boosting a car battery. If you're using it as a personal charging device only, I would go for more power. I will be using it for my van, quad (when out in the back woods as a back up tool), and as a charger while in the woods. Quad can charge it up while riding. Keep in mind this is a very portable unit. It also comes with lots of plug in attachments. Hope this helps!

I hate to say that this item pretty much served as a paper weight. On the several occasions that my battery died, the Wegan EA2045 didn't help to jump start my 2010 Acura at all. It turns out that the battery was completely dead and my car would start only after a "traditional" jump start. It did charge my cell phone while I waited for someone who was able to help with a jump start :) If you do choose to purchase it and you're not satisfied, you'll find it very difficult to return as it's considered hazardous material as I found out. Amazon and the manufacturer however were awesome and refunded the full amount. Good luck! I hate to say that this item pretty much served as a paper weight.

If I had a car I'd use a higher ah battery stand alone and attach an inverter... Or a regular back up car battery with inverter if I never needed to use jumpstart feature.

The max amps on this one is only 200amps. The real question is how much does it take to start your car? Most cars would be more.

Hope it works out for you. I had some battery issues in the beginning. After manually charging the unit, it seems to maintain a 3.85V charge or better. Time will tell if this makes a difference. And for $250, you'd think they would include a twenty-five cent mini-USB cable to charge it up.

I would recommend upgrading your alternator. Typically for every 10amps you get 100 watts. This amp will probably not get enough power and may cause damage to the amp or over work your alternator causing it to burn out. I have 2 of these amps in my car with an upgraded 200 amp alternator and a optima drycell battery.

Schumacher told me that if the battery is dead to connect it to a good one in a nearby vehicle for about 15 minutes using jumper cables to get the dead battery up to about 3 volts because their products won't charge a battery that is "dead-er" than one having less than 3 volts in it. After the 15 minutes, you can detach the jumper cables and use the Schumacher unit to increase the charging of the battery.

They don't make that point clear in their advertisement which is why I bought it. The paper work included with the charger states that is does NOT work on a drained or dead battery. Save your money and get AAA instead. They are always able to start the car for you when your battery is dead!
