Had to jump start my wife's car last night and started looking for some alternatives. Found this on Costco and seems to get mostly positive reviews. Normally $59.99, but on sale for $39.99. Although it states support up to 4.0L gas engines, the reviews seem to say no for V8's. But, if in doubt, there's always Costco's return policy to fall back on. Expires 2/11/2022

You'd be surprised. I've jumped many friends cars with something like this. Way easier than grabbing cables and moving cars
Close to 0%. But these don't need to be fully charged to function. I have a similar device that was sitting in my trunk for close to a year that was able to start my car with a dead battery in the middle of the night.
For years all of our cars have had a jump-starter like this one and I recharge them (more like top their charge up as they've never been fully discharged) every six months, or after using them, and they've never let me down. They've come in handy many times (more often for easily jumping someone else's car). It's still amazing to me that something so small can jump start a car! I think having one of these is a no-brainer.

Heck, my wife made fun of me when I bought one for her car a few years ago. She sort of patiently watched me show her how to use it before I put it in her trunk. A few months later she had a dead battery when she was out and about. AAA said they could be there in 45 minutes. Thankfully she remembered how to use it (it's easy) and was back on the road in minutes. She has sung it's praises ever since. Smilie

Quote from webdoctors :
In the past I had the lead acid ones, and they ALWAYS were dead whenever I needed to use them. It could be literally a week later and they're dead. The Lithium Ion ones are very different, after a year the lights show 3/4 charge (but I think this is misleading and wouldn't risk not charging it yearly).

I;m not a mechanic and I don't know anything about brands but I'm assuming these are all pretty similar (since same tech and pretty mature now).
Had a lead acid one that lasted well over a decade (things lasted much longer back then?). You just had to keep it topped off to extend the life. With these lithium ion batteries, keeping them topped off shortens battery life, the reverse. But they're so much smaller and lighter, and are often much cheaper to boot. So it doesn't matter if they don't last as long.

What are the chances that you have a dead battery in the middle of nowhere out in future AND you have a fully charged one of these jump starters in your trunk ready to rescue?

So, car batteries only die if you're at home or in a populated area? That's weird. My car battery didn't get the memo. Just 2 months ago, I was heading home when my car died, while I was driving, and no one was around to help. I had to have someone come meet me to jump it, while I was pulled over on the side of the road. This would've been incredibly handy.

Also, this DOES NOT need to be fully charged to work.

I bought one like this at Costco a year ago but I think the brand was Type S or something like that. It's been awesome and I've used it a lot.

Another use I found is taking it with me to the junkyard to power cars without batteries so I can pop the trunk open. I make sure to bring it every time I go since the cars never have the key in them.

I used mine to jumpstart my riding mower for a year. Those darn motorcycle batteries have gotten so expensive. This was cheaper then a new battery. Old mower with one of those small batteries, not the U2.

I also bought the Type S for $59.99 at Costco, I ordered this to compare & will keep one & return the other. I want to check out the lcd screen since this one has a battery check option.

I bought this jumpstarter and it was crap. Replaced it with a "type s" one that they also sell and it's way better

Isn't 8,000mAh pretty weak?

I've seen some around 50,000, more expensive of course, floating around. But they have the ability to charge cars, multiple phone, and laptops for days.
IT's the amperage that's weak.

I got the Noco GB50 on sale a year or two ago on SD and it's 1500A.

I started up so many dead cars with one similar to this, actually a cheaper version. The battery pack was dead on occasion but still got the vehicle to start. Or in the freezing cold too.

Got this when it wasn't on a deal. It wouldn't jump start my 2017 Subaru Forester 2.5 with a new size 35 battery and the jumper fully charged. It was also right after I replaced the battery after that one lawsuit against Subaru for faulty batteries.

Anyway, I returned it for not working. I guess I should've tried it on a different car, but I didn't want to wait in a parking lot hoping someone needed a jump start to test it out of a different vehicle. That would be a little weird.

Guess I will give it a another try; better to have it around just in case. Thanks for posting. Not sure why I wrote that story, but it was just my experience using this exact jump starter.

FYI, some starters cannot start an absolutely empty battery. Like Gooloo, that has some kind of sensing and won't work unless it detects some voltage/resistance, i don't know.... This proved to be my main issue as the battery, when it's dead, is really dead - kids left the lights on and such.

Bought some cheap Yaber from Amazon - cheapest i found hoping this sensing logic won't be there. Well, it's not there, works great. Don't know if i am missing on safety but used it many times so far.

Also, don't know about this one but Type S from Costco was crap compared to anything on Amazon.

Most of these companies exaggerate the amps on their jumpers. So this being listed at only 350A is pretty scary.
After watching a bunch of YT videos and reviews, I decided to go with 1500A model as my Honda and Toy are only V6. I got a Nexpow from Amazon last year and it recently jumped an Infiniti full-size SUV with no problem.

I have one of those old school huge battery jumpstarter things I bought close to 10 years ago at a pepboys, maybe it's time to switch to something smaller like this.

Are you sure that huge battery jumper still works? I've had mine 5-6 years and charge it every month since I use the air compressor on it for tires. I needed to jump my car recently and it barely had enough power to turn over the car.

I was just wondering.
If someone has one of those fancy sports cars that require Hi-Test gas for the high compression engine....would that require a higher current device?

Yeah I'm having my doubts these days. I only had to use it one time in the past, and it worked fine back then, but the battery seems to be acting up. I was using the air compressor for the tires when the battery indicator showed 75%, but it ran out of juice in the middle. I did top it off maybe a few months ago, so it might mean the battery can't hold a charge anymore. (which is why I'm looking at this post and a few other smaller jump starters)

Quote from webdoctors :
One really bad thing is the USB-C is only for input charging, the output is just USB-A output. That's a pretty big con considering you're much more likely to use it for charging than car jumping most of the time.
USB-A is 5V DC, 2.5 Watts (0.5A). Later revisions upped this to 4.5 Watts (900 mA). Pretty much only good for charging phones and powering small devices.

Plain USB-C is supposed to go up to 5V, 15W (3A), so is a bit more expensive to implement. USB-C PD negotiates a voltage with the device (up to 48V, 240W now, though most top out at 15V, 65W). So is most expensive to implement, but I'm hopeful it will eventually replace the ubiquitous 12V cigarette adapter for everything DC.

Quote from theking_z :
What are the chances that you have a dead battery in the middle of nowhere out in future AND you have a fully charged one of these jump starters in your trunk ready to rescue?
The usefulness of these devices depends on the chances that you need it, OR the consequences if you have a dead battery. I originally bought one to use on a boat I took offshore fishing. A dead battery while 60 miles offshore can rapidly turn into a life or death situation.

Most of them can be kept charged by leaving them plugged into your car's 12V cigarette adapter or USB-A. If you carry one of these in your car, it should always be fully charged.

As someone else mentioned, they'll see far more use as a jumbo battery pack for mobile devices. So make sure you get one which will be compatible with your devices for that purpose.

Quote from lui1828 :
I had those old school jumpstart for 10 years too.. It is junk now. The lead acid battery died
years ago. .
Lead acid batteries like to be kept between 50%-100% charge (actually 50%-90% is better). If you let it dip below 50%, its capacity will rapidly diminish and it'll only last a few dozen cycles or 12-18 months stored that way. The lower you let it go, the worse it is. They self-discharge about 5% per month, so fully charging one and leaving it in your trunk for a year drops it below that 50% threshold.

Li-ion batteries like to be kept between 10%-90% charge (20%-80% is better). Charging them to 100% or discharging them completely diminishes their capacity and reduces their cycle life. They self-discharge slower too (usually 1%-3% per month), so are safer (in terms of holding a charge) if you go 1+ years without recharging.

Their downside is a nasty tendency to go into thermal runaway and catch fire/explode if punctured, or you attempt to use it after it's been discharged below 0% or charged above 100%. They're all supposed to have a controller which permanently bricks the battery if it goes below 0% or above 100%. But some cheap Li-ion battery packs lack this. (Notably the hoverboards which were all the rage a few Christmases ago. Cheap Chinese manufacturers put a plain Li-ion battery in them without a proper controller, and many of them caught fire.)

Though to be fair, if you puncture or tip a lead-acid battery, it'll spill sulfuric acid everywhere. That's why gel cell and AGM batteries were invented - those hold the acid in a matrix so it's less likely to/can't spill out.

Quote from CleverGoat1310 :
i have a similar one that didn't recognize a completely dead battery (showed fault) but worked when it had a few volts.

My friends heavy duty one jumped it just fine
That was probably the protection circuitry. 12V 350A is 4200W, which can melt metal if you connect the two leads with a short length of wire. So to prevent you from accidentally creating a short circuit, the protection circuitry will only allow it to deliver full power if it senses a battery present (indicating you've connected it correctly). If the battery is completely dead, the protection circuitry assumes you've hooked it up in a short circuit and refuses to deliver power.

The better units have an override switch which lets you force it to deliver full power if you're absolutely sure you've got it hooked up correctly. The worse units lack protection circuitry entirely. They'll deliver full power even if you've hooked it up incorrectly, possibly damaging and destroying the unit and whatever you've connected it to.

Quote from Troublestylist :
I concur with the sentiment that these work great. But I've always wondered how they get by with such small cables and such high amp ratings. Even at that length, hundreds of amps would fry the cable.
The thickness of the wires which are needed is proportional to the amount of current AND the length of the wires. The leads with the clamps on these are usually only 6-12 inches, vs 6-10 ft for jumper cables. So they can get away with wires only 20%-40% the diameter (5%-20% the cross sectional area).

Quote :
Which makes me think it's important to leave them connected for a few minutes to charge the dead battery... just like we do with traditional cables. Move the electrons over BEFORE you need them.

Anyone have experience with this? I don't recall my instructions asking for a waiting period.
There are three types of these.
  • Ones that can jump start the engine directly. (Lots of small Li-ion cells arranged in parallel.)
  • Ones which first charge an internal capacitor, then that capacitor jump starts the engine. (Usually just 3-4 Li-ion cells arranged in series to get it above 12V.)
  • Ones which you plug into a cigarette lighter and wait 10-20 minutes, while it pumps enough juice into the car's battery to allow that to crank the engine. (3-4 Li-ion cells as in the second one, but lacks an internal capacitor.)
While any of them can help jump a car with a dead battery, there's a pretty big difference in convenience and expense.

And the length of time. I suspect these heat up a bit and would never be considered acceptable for "normal use".

But by limiting operation to a few seconds... no issues.
