Yesper 4000A from Amazon for $96 ($5 off with coupon VISAFIVE). It also comes with included EVA carry case.
Reviews seem to indicate it’s very similar to the Gooloo GT4000S (possibly the same factory).
CamelCamelCamel.
Thanks for sharing - have you purchased this one?
I made a purchase and will receive it tomorrow.
I hope it works well. My old starter pack doesn't hold enough juice to start a 3.2L petrol engine, probably because it has been sitting there for too long.
Just received mine
Quality is excellent!
Came with 78% charge. Currently have it charging @ 32w through wall charger.
Very happy
@punkel: Received mine just now.
Fantastic thing, tried it straight away and started my dead vehicle like a breeze. Only took 5% of the battery.
You need a 100W PD charger to take advantage of the fast charge. It charges at a solid 103W, they are not skimping on wattage at all. Brilliant.
@charmandad: Great to hear!
Which 100w PD are you using?
So glad I went this over the Gooloo (almost $70 more expensive)
@punkel: I'm using Anker, but I would say just wait for the deals, they come quite often.
By the way, are the buttons on your power bank tilted? I'm not sure why, but for mine, the strip of buttons has one long edge significantly more raised than the other.
@easternculture: I'm basically starting with no battery.
That thing has been sitting there for 8 years.
Now unavailable
Showing as in stock still
Many years ago, about 8, bought from Aldi such device on super capacitors. Was about $70, made in Australia.
No problem at all. Still use frequently as a power source for spot welding.
Liion battery won't last more than a couple of years, as you need to keep it fully charged.
My other one, Liion from Costco, was about $90, battery dyed after one year.
It is the reason why Car Jump Starters on Supercapacitors are not popular anymore.

I still gave a 10k mah xiaomi powerbank bought in 2014 that fully charges my s25u and still has charge in it. Ive also left it in my car in the hot summer for months every year.
Liion chemistry more than 10 years ago for power bank wasn't for high current. Max for 2.5A.
But to achieve hundreds or even thousands of amperage, which I think need some specific chemistry.
With different life span.
But to achieve hundreds or even thousands of amperage, which I think need some specific chemistry.
But you are only generating that high amperage for a few seconds a few times a year as a personal user. And that high amperage only drains 1-2% every time you jump start.
So i dont think its fair to use that argument that an older Lithium powerbank would last a longer time because of this or vice versa i.e. a newer powerbank wont last more than a couple of years.
@easternculture: I didn't mean newer powerbank, I mean car jump starter, to achieve such high current used different chemistry and technology. Such battery is more keen to self discharge and shorten life span. Regarding 1-2% drains is wrong, My Costco car jump battery claim max 4-5 times car starts, which will be less in reality. 2-3 starts make it flat.
@simb24: My gooloo only goes down 1-2% everytime ive used it to jump start.
It was at 85%, used it about 8 times and when i charged it a few weeks ago, it was at 70%
I only use ones with tyre inflator
Yep, same OEM.
Exact same button/screen/port layout, and exact same style for the accessories.
Those with 100W pd charging are nice, granted you get the 'new' technology. Not sure about the battery longivity though, might be just similar.
