In the same boat and interested in super capacitors .. i carry alot of power bank so i should be ok during camping as thats when my SUV battery died ( no driving for three days + too many times open / close power trunk , doors etc etc )

Yes, I would be interested in any thoughts/comparisons on the Shell SH924 Jump Starter with 24000mAh Portable Power Bank Charger from Costco.

https://www.costco.ca/shell-sh924-jump- ... 99358.html


as compared to the NOCO Boost HD GB70 2000 Amp 12-Volt UltraSafe Portable Lithium Car Battery Jump Starter Pack For Up To 8-Liter Gasoline And 6-Liter Diesel Engines from Amazon, Canadian Tire, etc.

Trying to decide if I should buy one of these from Costco….

https://www.costco.ca/CatalogSearch?dep ... p+starters

Or a Noco brand from Amazon…

https://www.amazon.ca/NOCO-GB40-UltraSa ... NrPXRydWU=

Or a Schumacher that uses a lead-acid battery. Upside with this unit is the AC inverter feature so I can use it to power my router during outges. Downside is its heavy ~20 lbs vs 2 lbs for li-ion based ones …

Getting the Most from Your Jump Starter

This is a good blog post from Clore Automotive. One notable thing it recommends is charging them every 3 months, except if left in a car in cold climates, then charge monthly.
I solemnly swear, to never assume I have an inkling at which direction the market will head, and to never make any investments based on a timing strategy.

Looking around myself, and came across this one for $125, but I have no idea how good or not it is!

Schumacher SJ1330 1000A Jump Starter Portable Power with Air Compressor

https://www.amazon.ca/gp/product/B0789DLKB5

Their 800A is priced at $179.97 ship/sold by Amazon, so was this a price mistake?

https://www.amazon.ca/gp/product/B07896CCTP


OMG, the Shell Rotella SH924 from Costco is a beast...

It's overkill and can start a tractor trailer, but a beast none the same!

Bought it for $169.99! :)

About to pull the trigger on the Shell from Costco. They no longer seem to have the larger model SH924 (24000mah - 88.8Wh) and instead only the slightly smaller version SH916WC (16000mah - 59.2Wh). Hopefully it will be enough to do the trick.

Reading all of this thread and discussions all over the place, it seems like these Lithium Jump/booster packs are very much a YMMV situation. Sounds like the batteries themselves can have enough power to properly boost a car (even up to the sizes they indicate) but there are a few catches. The internal batteries have to be configured properly. And then the unit itself has to be designed correctly in order to access all that power. Even with those two things, you aren't out of the woods yet. Then manufacturing Quality Control and consistency comes into play: everything has to be constructed and attached properly so all that power can flow without being limited. Some shoddy soldering, a pinched wire, loose contacts etc, and your unit might end up reduced in it's power output despite the product itself being well designed. With the relatively low price of these items, it looks like the quality of each individual unit can vary a lot. And then degradation comes into play. There is the usual lithium battery degradation that happens over time and is hastened by temperature extremes (hot and cold), and then there is the unit itself. These packs can put out a lot of power in a very short time, which means considerable heat is generated (many units can only do a few boost attempts in a row before overheating/shutting down). This heating (thermal stress) can also wear out the internals/wiring etc, so even if your unit was constructed properly, after dealing with heat due to multiple uses it could stress wiring/joints, and that could reduce your power output. It's really hard to guess which ones will have long term durability.

So even if you do get a good unit that works initially, it sounds like after a period of time/uses it might stop being up to the task. Which isn't great for an emergency type device, to not work when you finally need it. Lead Acid batteries seem to be the preferred alternative, in that they are much more simple/reliable and have way less issues like above, but they are so heavy and bulky that I'd still prefer a compact lithium booster. So I think trying a Costco unit with their solid return policy might be the way to go.

picked up a tacklife t6 at an amazon liquidation sale. It works and is pretty much new. $35. Not a bad deal.

I wouldn't take one of these booster packs if someone paid me money to use it.
Inside of these packs are LiPo cells, which are only used in RC models, because of their extremely dangerous chemistry and tendency to catch fire.
D.I.Y. ebike community tried to use these 10-12 years ago, but gave up after multiple garage and house fires, even some deaths, AFAIK.
Here's what's inside one of these packs, 12 Ah, 400 Amp peak power:



3 Li-Po cells, with some electronics. At 12 volts and 400 watts it has an output of 4.8 kW!
I assembled my own OpenEVSE L2 7.2 kW charging station, trust me, these packs are not designed to handle 1 kW of power, never mind 5 or 10.
On Amazon NOCO Boost Plus GB40 is the number 1 bestseller in automotive. One reviewer on the first page says it blew up after first charging.

What does LiPo battery fire looks like:

Eh you fear mongers know LiPo batteries are in everything nowadays, from USB power bank to your laptops and phones, do you live your life like there's a bomb next to you every other second?

Too bad Amazon no longer sells any of these besides Noco, anyone knows why?

Most aren't certified for sale in Canada. Same with these crappy cheap battery testers/chargers and many other electronics on Amazon...
