The junk parts and flimsy cables have no problem jumping off my V8 Tundra, riding lawn mower, ATV. So I'm happy with my POS jump starter


That's fine, mine can start my V8 truck with the battery completely removed. Go try that with yours.

Also, mine only has a 3%/month self-discharge rate so the lithium boxes really don't have any advantage there.

You are arguing just to argue at this point. The op stated he wants something small, so your recommendation of a 20 pound 16x14x5” brick doesn’t fit the thread. We get it that the jnc660 might be better at jump starting cars, but if you don’t have room for it in your car then there is no point in buying it

Once the arguing stops check out the Micro Start products as I posted earlier.

These things fit just fine in any car. I kept mine behind the seat of my reg. cab Ranger while in PA. Looking for convenience options in a device you want to depend on for emergency? I'm arguing because I did my research a few years ago and trying to save the OP a future headache. I didn't want to spend money on a gimick that works when the conditions are ok, I wanted something capable in the worst-case. My alternator started dying a few hundred miles from home on a return trip to PA after a Christmas leave, I relied on that JNC to limp my Ranger home for over 100 miles then used it to give my Ranger's battery enough charge for a few mornings to get to my office until I could put in a new alternator. Laughable what some of you will argue for, cut corners on, when it comes to things like this.

Micro Start


my dad has this in the 400a version. I didnt think it was strong enough, but it jumped my 5.3L very easily with a completely dead battery.

I've run a 4.7 tundra off the microstart with no battery in there. I just wanted to know if it would.

I’ve seen plenty of videos of the small lithium packs jumping a car with no battery connected. NOCO included.

Thingnis you did your research years ago when battery tech specifically lithium has increased exponentially.

As I stated in my very first post I believe lithium is the way to go in this sense and not a 20lb lead acid brick that I have no desire to be sitting loose in the back of my truck whereas I can throw a lithium battery version in a backseat pocket and be good to go.

Again I’ll restate noco might not be the best specific lithium pack but I’m not looking for a jnc660 or any other type of lead acid.

How about I get a noco gb70 (JNC318 does not have the low voltage capability to jump with no battery connected whereas noco has a low voltage override) and see how many times it can jump start your bronco no battery connected. From everything I have seen my money is that you would be very surprised.

You might get a few starts like that, but again it's 18Ah for the best Microstart and 200Ah+ for the mid-range JNC. And you've paid more for that 1/10th capacity. Then there's the fact that lithium doesn't have the cold-weather performance like the AGM and ultra-capacitor starters (anybody with lithium cordless tools knows this). Not a huge deal in the South most times but when we eventually do get some really cold days, you are supposed to store those lithium jump packs indoors (like anyone will remember but it is in the instructions). I don't see the utility in paying $90 for something less capable than a $120 product just to save 15 lbs of weight. It's like buying a $69 Ryobi drill kit when the $99 Dewalt/Makita kit is on sale right next to it.

Within the last 5 years and no, lithium battery tech has had no such improvement. Some idiot in the OT said that too. Those packs are using the same battery tech as lithium laptop batteries had 20 years ago.

I'd be a bit smarter and get the JNC8550 but the JNC318 has a pre-heater to deal with the cold weather issue whereas the GB70 doesn't and the low-voltage override isn't as much of a feature as you think. Difference between a product designed to jumpstart a vehicle vs a glorified powerbank.

Posted this with no concept of irony.

OP, if you're looking at noco, I have a GB40. Jumped the wife's car off twice and the boat off once with it so far on the first charge.

Could step up to the GB70 if you need a little more push.

They also have a nice case for it on amazon for $15.

The weight isn’t the issue near as much as the overall size and the inability to store the lead acid batteries.

This isn’t an argument about lead acid versus lithium. For my needs the lithium is the clear winner. Apparantly for you the lead acid capability over convenience was your winner.

You have to understand that not every deer needs to be shot with a 300 winmag sometimes a 308 will get the job done just fine.

Now noco gb70 vs noco318 is a valid discussion and one I’m glad to entertain.

But if you have nothing intelligible to add to this discussion please gtfo

But its also a lot larger and takes up more room. its called a compromise.

NOCO never does very well in the tests on Project Farm. Several higher performing units on those videos. Audew comes to mind.
