I’ve used a jump n carry as a car battery before. We were reviving a Toyota. It was a small 4 banger but the jump pack was the only battery connected. We cranked and crank and started that thing a dozen times or more. I was really impressed with the jump pack but since it’s pretty much a car battery with jumper cables attached it’s makes sense why it would be able to do it.

I have the JNC 660 and its been wonderful for about 12 years now. Only just recently had to replace the battery.

I have the same lithium-ion jumper pack and I love it. I've had for about 3 months and used it a few times. I live in Chicago, so it gets pretty cold here. I noticed it works best the closer it is to 70 degrees. It was 5 degrees last week and my car wouldn't start with the pack connected, so I put the pack inside my jacket, sat inside the car for 15 minutes, and let my body heat warm up the pack. I tried it again and car started right up.

A useful observation! That could save someone's bacon! Hey, if you wore a bigger coat you could just do that with the car battery! More seriously the little packs can more easily taken inside in really cold weather. I've even taken them into restaurants, work, libraries and coffee shops in sub zero weather as I usually have a backpack anyway, to carry stuff. I've charged it in some places too. Of course bringing it in at home, overnight is the main thing, at least when it's double digits below zero... normally I don't.

I think the cold lithium pack needs to be taken inside, warmed to room temperature, charged overnight, and retested. That would rule out any failure of the battery pack itself.

It won't discharge or charge at all at the temperature it was cold soaked to. Just letting it warm up above freezing or even above 0°F should get it where it works as well as the other.

If you tried to start it a few more times, it might start. The LiPo cells need to be warmed up. Starting it a few times cold warms it up really quickly, and you should be able to crank it over by then.

If you don't care about trunkability, you could also get a small lead acid battery light enough to lift on your own, and carry it in a milk crate or similar. Or a battery with a handle on it, like many now have. Set of good jumper cables and you have yourself a portable jump pack. Keep it on a maintenance charger and it should give years of service.

To be honest I prefer this crude battery and jumper cable method, most new jumpers have all these safety nannies that get in the way of starting a dead car. A regular deep cycle car battery has more cranking amps than any standard jumper pack on the market.

Lithium batteries have the advantage of holding a charge for a long long time, but they struggle in cold weather. Lead acid batteries do well in the cold, but they have to either me recharged frequently or kept on a battery tender.

I've got a lithium one.. They charge for a few hours and they're at 100%. Some wont attempt to jump if they don't see at least 10v on the battery... Mine is like that. It does the thing though on a 5.4L. I've got a second one coming that doesn't have that limitation and should be able to spin my motor easily. They're more for jumping batteries that are almost there, and just a little low vs. a completely dead battery. Handy to have. When I jumped my expedition with the one I have, I ordered a second one for my other vehicle... What he's seeing with the COLD pack is accurate. The lithium cells DONT like cold weather. Heating em up to 30-40F would be ideal. Mine will do it in the cold, but it takes a few tries to get that big amp pull to warm up the unit.

The problem with battery jumpers is that you might carry it in your car for months or years before you need to use it. If you don't charge it up on a regular schedule it might fail when you need it. That's why I am a fan of the capacitor type jumpers.

I was a friends house while he was working on an older ford dump (diesel). Batteries were dead, so he pulled out a Lithium Ion Jump Starter and Power Pack. that he got form Harbor Freight. Never hesitated... I bought one and use it when I go to bush-hog. My tractor is only cranked these days when I go to bushhog! Never fails bust-off that little diesel. I use mostly for the tractor, but I keep it in my wife's truck to make sure she doesn't get stranded. I also bought a Viking 1700 with the aux compressor. Got tire of flat lawnmower tires. The KOT's Meow. I have a 12' enclosed trailer that I keep my Hustler 52 in, and that's where the V17c resides. Along with tools. I call it my Mobile Storage. heh-heh-heh

Wire resistance is proportional to length. Shorter cables can get away with being lighter gauge. For the same amount of current longer cables need to be heavier gauge.

I appreciate you testing in true cold conditions since this is typically when batteries fail and which normally reduces the performance of the jump starters. As another comment listed, I think the best choice is an ultra capacitor version, because the cold doesn’t impact its performance and generally you can use the weak battery to pre-charge it… better yet you can get a hybrid which has the lithium battery combined with the caps and the lithium battery gives you another option to pre-charge the capacitors.

I had one of those JNC770R packs. Lasted under one month and only two jumps. They wanted close to $70 for round trip shipping for a warranty replacement so I chucked it and got a cheapo lead acid jump pack from harbor freight. Four years later, the HF pack is still working well on its original battery.

I've noticed more and more roadside/state/fleet/service/utility trucks and equipment with external anderson plugs for easy quick jump starting, especially on utility companies that mainly work up North lol 🥶

The only benefit I ever got from a lead acid jump pack is dead weight in my car for the winter. The couple I owned wouldn't start anything, even if the battery in the vehicle was just low and not dead. I bought a Li-Ion jump pack and it has started everything I've thrown at it, multiple times too without needing to recharge right away. Even our '87 Winnebago with a beefy carbed 454 in 30 degree weather just cranked cranked over like it was sunny and 75. More power to anyone that still uses old and aging acid batteries to jump start something, but I'll stick with the Li-Ion jump pack.

Thanks for the video! I'll just add a note to be careful with *some* battery-charger/starters when hooking them up without a battery installed. Really high amp charger/starters push out the high amperage by increasing the output volts. The battery acts as a energy sink and will then absorb the amps pulling down the volts to near ~14v even though the charger/starter may be trying to push out, perhaps 18-22 volts. The (dead) installed battery protects the vehicles electrical system from the too-high voltage. By removing the battery and hooking up such a high amp charger/starter, the vehicles electrical system see the high voltage and could damage some components. Check the output of volts of a charger starter before hooking it up to a vehicle without a battery.

If you find it on sale off season, ( which happens every other time since I have it working 100% all the time). I am left with a choice of saving a small amount of money and have a beaten up looking unit (which is what I have) and none of the new bells and whistles, like USB ports.

I notice once the engine turn over with the lead acid, it's easy to restart again. A fair comparison is let the engine sit for a day and restart with the Li-ion.

A lithium jump pack is designed to disconnect its internal lithium battery once it sees alternator voltage. It protects the lithium battery which needs a different charging algorithm. Cold lithium batteries reduce voltage and capacity. On Teslas the car has to maintain battery temp in order to charge it in freezing temps. The big advantage of a lithium jump pack is that it holds a charge for a year or more, something a lead acid won't do. Plus the life of a lithium jump pack is much longer, especially if both are used periodically. Starting a car independent of a partially discharged car battery is not the use case for these packs.

This is exactly what I've thought about doing,, but don't run into a dead battery more than once every 3-5 years so I've never bought one since they're $100 or more. The advantage of the super-capacitor jump-starters is that they can (allegedly) charge themselves off of a low battery, and store enough power to start the car. The thing I don't like about the battery based ones is that you have to keep the battery charged. Lithium and lead/acid batteries have self-discharge rates that they might be dead in 6 months unless you charge them. A super-capacitor charger charges off your car battery, your phone, or the wall. Honestly, it'd be cool to see a hybrid car battery that already has a super-capacitor in it, and maybe some temperature sensors that charge it up when it's extremely cold. Then you'd get extra CCA capacity, or just protect against batteries that are low on capacity.

It's called weight time power key factor of intervals of recharging lithium batteries win out.

Ben, you need to head over to Project Farm's channel, he did a very thorough testing of these units

When a Li-ion booster is colder than a few degrees F its ability to discharge goes way down. Won't charge or discharge at all while it's about 5F below. If you stuck the colder one showing 77% under your jacket until it was as warm as the booster pack from your garage it would've worked right away too. Cold weather saps the car battery the same way so if you don't have a booster you can use a small heater or a heat lamp to try warming the battery enough to crank over.

come on, let's destroy the control units! 💪🔥⚡ Caution: ⚡please always close and open the electrical circuit with BLACK!! DO NOT handle it as shown here at 0:05 + 9:05 + 11:05! Also/and especially when jump-starting from car to car! Tip: just remember: Red/plus ALWAYS stays connected for LONGER. And if just the engine control unit is broken ($2,000 to $4.000,-installed), then the problem was between the steering wheel and the driver's seat. So people, BEWARE: as I said, never connect in the wrong order when jump-starting! For the sake of your electronics and your money: Make the red contact good and tight! Then, when the circuit is closed (with black/minus): DO NOT TOUCH/wiggle the red one again before the black one is off again! If you suspect that the red one is not properly seated, first REMOVE THE BLACK one and THEN correct/contact the red one. Then put the black one back on... etc. If the black one sparks, it's not so bad, as the electric shock is "cushioned" by the battery.

yes Li-ion is not suitable for cold weather. LFE cells are much better for this application, but they are more expensive and bulky

Better to try the lead acid battery jumper versus a mega capacitor style jump starter

Negative does not go on negative, it goes on a ground. Luckily., the main reason is for sparks so the switches on the jumpers are saving you lol

I mean you tested one of the cheapest lithium jump starters I have a Noco gbx 55 you can hit overide if it doesn't detect a battery but it will remove all safety features

Did you hit the boost button?

I don't think that unit has one!

Acid battery in a jumper last about one year if you frequently charge them but lithim last longer but aparentally get affected by cold temp acid batt don't. I prefer acid jumper cause has more power to start vehicle and can be used to start a 10 or more vehicle depend on The jumper capacity.

Kick ass

at 9:10.. the jumper broken .. u can see the spark.. ⚡️ ⚡️

General question that has nothing to do with this video, but with prior videos that you have done on wiring a home. The question I have is: “is there a code for how much insulator sheathing (the outermost insulator coating on standard household Romeo) can be left inside of a electrical receptacle. In other words, how much of the outer sheathing must be stripped off (e.g., 1/2”, 1/4”) ? Thanks.

I keep lead acid in car at all times. Because lithium can be damaged when frozen or heated at temperatures that cars get to. I do have lithium that I keep in the house to stay warm. It is my goto whenever something needs a jump. I will never let it get cold or hot though. .

WE KNOW IT'S HERE!!!!!!!!!!!!!!!!!!!!!!!!

The lithium battery booster pack is clicking because it's disconnected from the car battery which requires it to need a power source to keep it running .These lithiums battery booster packs are very very tricky🕵‍♂️

HAPPY BIRTHDAY BROTHER ❤️❤️

I’m literally here because my vehicle won’t start. I have the big pack but it doesn’t work well or at all and I’m trying to see what would be the cheaper and more efficient . I have 2 little girls and the other day we got to the car, my battery died and Although I have regular cables I dreaded approaching strangers for help .

dipstick heaters are cheap and work if dont have oem block heater.

Hi u

Those things will last around 7 years then have battery issues, use it or not. Plus charge must be maintained once a month or battery will die sooner than 7 years. The lead acid battery could easily be replaced for around $40, just did this yesterday. I think the Li-ion is a throw away, could be dangerous if you don't know what you're doing and required breaking into the case and desoldering from the motherboard.

Lithium won’t start from Emptied battery sadly. A problem. My two lithium portables died same week after a year. Didn’t last long. Did do big diesels now won’t start even 2 litre diesels. Maybe a 1.2 petrol best

Had two lead/acid jump starters. Both died due to neglect. Unlike my spanners which just wear out in a regular civilized manner. Batteries are misery - you pay a lot, and they need caring for. Better to buy a dog. So can these pocket starters die from neglect too?

Rubin. Please protect your eyes next time you attempt to short circuit high current conductors. It would be a shame to say "the last thing I ever saw was a shower of molten metal".

That would be smart!

They froze one battery after messing with it and had the other battery at 35 degrees, granted the foxpeed probably would not work well in this situation but the test is just not done correctly.

Worried all of them will start fine 😁😂🤣😅 lol!!!!

It's pretty simple why it did not work. These Lithium Jump Starters don't work well when they are cold. The battery inside has to warm up for them to work. To make that happen use short bursts. Just turn the key on and off a few times and kick the motor to get the battery warm. By the 5th time it should be warm enough to start your car or truck.

These Lithium Ion jump packs should be called charging packs. They are designed to give enough charge to your car battery to enable a start. As shown they cannot substitute for a car battery. A chunky lead acid such as Snap On will start anything, with or without the vehicle battery connected.They also lie about the capacity. They add the 5 v capacity to the 12 v capacity neglecting to say that both voltages are generated simultaneously by the same battery. How dishonest is that? These Li-on packs are designed to start a car where the battery has gone flat accidentally by leaving lights on etc. They need a little time to put enough charge back in to enable a start. They cannot help if your battery itself is faulty. To cover all eventualities get yourself a good quality lead acid. My SnapOn 17Ah has given me good service in the car trade for many years although I have had to replace the battery itself 3 times in 15years, but at a fraction of the cost of the jump pack itself.

Batteries go to hell when they get cold... Warm that one at 77% up and see if thatll jump it!

The jnc 660 is a much better unit than the 770. That being said any jnc will outlast any cheap China lithium jump pack.

dam u modern flue injecting for starting all the vehicle. I don't miss the carb days at all. :)

trying to use a tiny SLA at -15F to start what a gigantic SLA couldnt. I dont see the logic there. Only if the jump pack was a small Silicate Salt based battery. Also that jump pack is 2AWG CCA or Copper Clad Aluminum, its what they all are to give you false sense of security.

The only reason I use led acid it's for the price

Many better lithium-ion jump start packs have a "boost" feature for when the battery is too low to be detected.... sorry to your sponsor but that's a crappy example of a lithium ion jump-starter. Also as mentioned lithium-ion loses most of its output in extreme cold. Warm it up and try again.

Think about very cold electric cars

Most EV's have absolutely no problem in the cold, though you do see reduced range. The Nissan Leaf is the one that suffers the most, but this is because Nissan cheaped out and went with an air-cooled battery instead of a heated/cooled unit like everyone else uses. (Supposedly the next Leaf will fix this) Normal EV's will run their battery heater/cooler even when the car is off, if the computer says its too hot/cold out, or if you set the car's computer to do so. For example, if you leave for work at 7am each day, you can tell the car to pre-heat the battery at 6:45am. Or better yet, tell it to pre-heat the entire car, so you do not need to defrost or defog at all, and the seat heaters can be readied. Of course this, and lithium-ion's reduced output at low temps, means you do lose some range in extreme cold. Normal EV's can lose ~20%. Nissan Leaf's lose 35-50%. And for the record, I'm not a super EV evangelist. Just a mechanic who works on anything with wheels, and have my certs for EV's. I'll get one when I can charge it at home, but the current rental doesn't allow it. Booo~!

I just have to wonder why we can make electric cars using lithium batteries, but no one makes a full sized lithium starter battery. I would ike to be able to go 10+ years on a battery instead of the typical 3-5 years I get out of a lead acid.

They are available, but still pretty expensive. I expect that to change in the next few years. For example: shop.advanceautoparts.com/r/car-technology/lithium-car-battery

Lead/acid is still the best battery for rapid discharge as is needed for a starter motor. Lithium is good at steady, gradual discharge as is needed for a continuously operating piece of equipment in a relatively steady state. The lithium jumper pack contains and charges a large capacitor with the lithium cells and the rapid discharge of the capacitor is what boosts the vehicle battery. In fact, capacitors are often used in extremely cold climates to start heavy equipment because they're not subject to as much temperature degradation as any chemical battery, including lead/acid. Now of course, you cannot run anything on a capacitor continuously because it is more or less an accumulator of electrical energy, discharging its stored energy rapidly but cannot provide steady flow nor steady voltage. The point of my comment being, lithium cells are not a viable battery technology for intense rapid discharge, they have their place in other applications for sure, such as phones, computers, etc. As for the temperature issue, while lead/acid degrades under colder temperatures, lithium really takes a nose dive at some point, definitely not a cold weather battery.

Cost?

The Foxspeed is not designed to operate in minus 15 degrees...period. A better quality Lithium will work fine that is designed for minus 40. Costs about $150. Why carry a lead acid battery around with you?

Lead acid jump pack batteries don't self combust😂

Fox peed? really

¿quien chingados le dio pulgar abajo a Benjamín? ¡Si el es muy chingon, Saludos desde Michoacán México!

Lion doesn't like cold

it doesn't work, people don;t normally have two jumper packs.

Watch how long it takes to charge your lithium! 4 HOURS !!!

What happened to your battery? A fox peed on it.

foxPEED on your car

I want your car batteries. I don't drive for 10 days and the car won't start.

To many "I thinks" and "maybe". You didn't plan well and you are just guessing. It's hard to take this "test" seriously.
