solo jumper cables

What do you all think of this thing?

https://www.costco.com/Peak%C2%AE-450....11612553.html

Are you more likely to need to be able to jump your own car with a thing like that than you would be able to find somebody else to hook up to the other end of a traditional jumper cable set?

Is it just a matter of how charming you are?

I have a similar device in my wife's car, so that she can jump her own car as need be without waiting to try and find someone to give her a jump. I also have conventional jumper cables in all the cars, so that we can give a jump to other people in need.

Jumper cables? You don't need no stinking jumper cables.

I have noted, more than one time, that these "jump boxes" are commonly dead and worthless by the time you actually need them. They contain a little battery as well and sit and go dead over time unless you have paid attention to being sure it is charged on a regular basis.
If you (or whoever needs it) is commonly in a place where there would be no one to jump with traditional cables it leaves little choice.

This. Same goes with my electric emergency air pump, so I stopped carrying it in the trunk. I have regular jumper cables and one, also made by peak, that just hooks into the cig lighter. I've never had a situation where someone isn't willing to help out with a jump... Now if you live out in the middle of nowhere, it might be a different story.

Ha! I think I know that guy. I used to own a 240z that I had to start by bridging the two poles on the solenoid.

I used to have to do that w/ the Dodge Dart. The finish on my swiss army knife blade was all pitted from the many many times I had to do that.

One very cold night I needed a jump and couldn't get one, this was 20+ yrs ago, but it hasn't happened again. I just have that memory in the back of my head.

I have a similar one that I use, minus the air pump. I use it primarily for long road trips. So I make sure I charge it up beforehand. They come in handy because you never know when you'll need it being so far from home. Otherwise, I just keep a pair of good ol' jumper cables in the trunk for daily driving.

That's ****ing brilliant. I gotta remember that and just start carrying a spare battery around with me all the time. Making sure the wrenches line up is a good way of feeling alive.

With maintenance free batteries of today, a battery lasts 4 years or so. Just test them periodically (every year or so after a couple years) and you won't need a jump or this device as long as the car is driven regularly

The problem with a lot of those portable jump-starters is they use the same crappy centuries old lead-acid battery technology that's dead in your car. They have very low power-density for their weight and they have self-discharge rate that'll have them dead within 2-months. So you have to keep them topped-off with regular charging just like a car battery's that's not being used.

Also cold-cranking-amp ratings are primarily for cold-weather. Lead-acid chemistry efficiency goes downhill very quickly as the temperature drops. So at -10F, a battery that's good for 700 CCA @ 70F may only be putting out 150 CCA. So that's why many battery manufacturers boast high CCA, so that if you're caught in a blizzard, you can still start your car and get out.

That's all old news with the new LiFePO4 batteries on the market. These latest lithium batteries have a much safer composition than the laptop batteries that have been exploding. You can put a LiFePO4 battery on top of a fire and it won't explode. And when the casing melts enough to ooze the guts out, the fluids that leak out will actually put out the fire. And these batteries have the highest power-density of anything out there. I replaced a 11-lb lead-acid battery in my motorcycle with a 1-lb Shorai LiFePO4 battery that has an even higher CCA rating of around 150 cca. I even tossed one of these batteries in my and my wife's car's glovebox. AND they don't self-discharge like lead-acid batteries. You can keep one on the shelf and after an entire year, it will still have 99% of it's charge left.

Here's what they can do:

I have one a carry in my truck, got it setup so it is always charged, also carry jumper cables, tow rope, a more than basic set of tools, air pump, an electric impact wrench and often a hydraulic floor jack. Wife carries standard jumper cables in her car.

Seriously, roadside assistance. $120 a year, pays for it's self after one use. With all the women in my house it has been used at least once a year. Not to mention not having to go on a rescue mission and missing work.

That's why I married an old farm girl, WoIndy is always helping other people when their cars will not start.

I used to carry a hydraulic floor jack. Those were the days... never an impact wrench though.

I used AAA+ (which works in Canada and also reimburses for non AAA towers when those are all that are available) to get towed from St Stephen ME to St George NB to Moncton NB to Truro NS and saved enough to pay for AAA+ for the rest of my life and probably my kids' lives. That was 20+ yrs ago but every time I've called AAA since they take at least hours to respond so maybe roadside assistance is the way to go.

I need to look into one of those LiFePO4 batteries. The 2 shops in the stripmall where my office is don't have'em.

I had a power inverter that would run it and the electric impact, once I got my air one, I figured might as well through the electric one in the truck. It's came in handy a few times.

Good way to get a battery to explode by setting off the hydrogen gas with sparks. No doubt these connections are loose and sparking.

In fact when I jump my car or any other vehicle, I always make the last connection not near the battery, but to a good ground on the engine, or better yet, on the chassis.

The last connection is the one most likely to spark (as it completes the full circuit) and you don't want that spark near either gasoline or hydrogen gas (often given off by wet cell batteries).

Ya don't even have to do that much testing... just be aware of how your vehicle is cranking... the first time you hear the slow start... think new battery. Of course have it tested first, just in case it is just dirty connections or some other problem.

What happens to most folks that need an emergency jump is either they ignored the signs (slow cranking, poor starting) or left their headlights on.

Yeah, other than when I had alternator issues, my only problem with batteries was due to lights.

Or a sudden cold snap, alternator going out, actually I can think of lots of reasons for needing a jump start yet having not ignored any signs.

I was going to guess thy were Brazilians, given their excellent kludging skills. But the battery is labeled in English.
