The other day we wrote a guide to help people choose a battery pack for recharging their mobile devices, but we never considered that some people might want to also use it as a jump starter for their car. You’d think that it would require a really large battery pack to jump start your car, but according to the manufacturer, this thing can be used for jump starting purposes up to 20 times if fully charged. If you have to jump your car at night, you’ll be glad to know that it comes with a built-in LED flashlight, strobe light, and SOS signal flash that lasts for 120 hours for when you get really lost on an island or something. It's all a matter of voltage and amperage, and it doesn't take that many watt-hours to start an engine. If this works well, I'll probably recommend this to several people who are currently using heavy, bulky portable jump start packs to power portable electronics in the field.
The battery has a capacity of 12 amp-hours, but the documentation doesn't say how many cells this thing has.
Multiply the number of cells by the amp-hour capacity of the pack, then multiply that by 3.7. My biggest questions are about the physical size, build quality, and effective battery life. Cold cranking amps (CCA) is a measurement of the number of amps a battery can deliver at 0 ° F for 30 seconds and not drop below 7.2 volts. That little battery has got to have some real capacity to be able to crank off a dead car or truck vehicle !! I stashed this unit in the glove compartment, then headed off to Arizona for a camping trip to the Grand Canyon.


Well, since we weren't really moving the car around much during the trip, the unit was needed another handful of times to start the car.
Several of my friends and acquaintances have purchased this device based on my experience and recommendation.
Specifically, I currently have a 12v 18Ah battery pack that I use for camping and for emergency jumpstarts.

It’s compact and lightweight, so you could easily carry it around with you, or just stick it in the glove compartment while traveling. You just  hook up the two jumper cable clamps — red for positive and black for negative, of course, and then attempt to start the car.
It’s got both AC and DC chargers, a big set of adapters for every device you can imagine, and dual USB ports to plug a standard USB charger into. It has a USB charging port on it, as well as a 12V accessory (aka 'lighter') socket, and an LED flashlight that's blindingly bright if you aim it at your face (so keep it aimed at the engine compartment if you're using it to hook up the cables).
I would be getting it to use as a portable power source for my iPad and some other portable stuff.
Compared to the current lead-acid packs, this should be a night and day difference in size and weight. So before accounting for inverter and charging losses, this pack might recharge a fat netbook battery to 90% capacity.


We've had so much interest in this product, it's amazing how many people have viewed that article considering how simple it was. If the price gets halved to ~$50, I can see it being a huge seller for geeks, non-geeks and casual gadget collectors alike.
Until then I was using a portable battery weighing over 25 pounds when I had problems with my car starting. During the trip, my friends kids managed to leave one of my doors ajar, leading to a dead battery. Thanks for reporting back - we've had a lot of people write in and let us know that it worked for them as well. I know they gave an amp-hour rating on the official specs, but the true measure of battery capacity is watt hours.
McKinley; The McKinley-Mac is made with two quarter-pound patties instead of the smaller patties used in a standard Big Mac. Most clamp directly to your battery, but some plug in to a power port in the cab and trickle enough juice to your car battery to turn the engine over for the 10 seconds you need to fire up the engine. Since I ride a motorcycle, many times I will go to use my car and find my battery has drained due to non-use.
