Probalby because these are more likely to start a larger car than those mini chinese jumpers.

As opposed to the large chinese jumpers?
These say they suit up to a 4cyl petrol engine, hardly a larger car. My experience with these is that they're too big so you generally leave them at home, and they don't hold charge for very long, so even after a couple of months they don't have the juice to start the car. Compare to a PowerAll battery pack - mine went uncharged for 6mths and was still showing 80% battery - needed to use it to jump start my 4wd (6cyl petrol) that was dead flat (no lights at all, no starter relay click etc) and it did so with no issues, and did it 3 times without needing to recharge the battery pack (in fact it's still showing 80%, and would likely still jump start the 4wd if I hadn't replaced the battery).

That's my experience as well with these archaic devices, the LIPO units on the other hand hold their charge and work everyone.
I got 2 of these handy PowerAll battery pack.no problem when you jumpstart car.
Check some of the reviews on those little lithium jump starters, wouldn't trust them at all.
Wonder what batteries this one has, I had a similar one a while ago and it had a 19Ah 12V AGM in it, for $35, that's not too bad.
I've got the 'PowerAll' Powerbank listed in this catalogue - $329, but its started anything from bogan bommodores, to Mazda 3's to Toyota Prado's without blinking an electron!
Seriously, if you get a good quality Lithium starter you won't be disappointed - you save a lot of weight an size.
One of the few times where smaller can outperform larger ;)
Do you mean 9ah? I don't believe 19 would fit in this??
First of all reliability, second price.
Cheap Chinese lithium batteries are heaps safe. Powering smoking hot hoverboards for years.
Korean ones are better, ask Samsung.
Ummmm .. so where is this advertised unit made???
More talking about the battery chemistry rather than the country of origin.
How much does this thing weigh? I don't mind the larger size as long as its light. And does it have that annoying feature where it beeps non stop when the battery runs low like the SCA ones?
What batteries are in these?
Biggest question is, what's the RRP on these? I have a battery jumpstarter that plugs in to the cigarette switch, does the job really well so I don't know if this would be any different to it. It took about 10-15 mins to charge tbh, same as this: https://www.amazon.com/Jump-Up-Emergency-Starter-Kimball/dp/…
For PowerAll battery pack people have to watch out ( counterfeiting one ).
I have a laser product from good guys that i bought with the recent $25 free codes i used 2 of them to bring price to $49.95. Its a little power bank with jumper cables. It starts my VX v6 commodore no worries as well as my partners mazda 3. Kids keep turning on the interior light on her car so over the weekend it went flat.
Careful with those. They usually simply have 18650s in them and abuse the crap out of them. It's literally the same as starting a car off a laptop battery - it'll work, but it's really not the safest thing to do.
I'm honesty surprised they can sell products like that in Australia…Ok many thanks. Will definitely take your advice. We carry jumper Cables in both cars anyway.

I have one like this but a better brand. The electricity went off the other day. Laptop had a battery, but no 240V for the modem. So I plugged a 12V-240V inverter into the 12V output socket of the jumpstarter to power my modem.
Would the small lithium ones do that?
If you can find a plug on a spare charger/etc that fits your router, you can run your router directly off 12v if it's a 12v router (without any charge brick - directly wired). The majority are 12v.
Even better, if you find a car socket charger for a GPS device or something that has a plug which fits your router, you can buy car sockets and wire it to a 12v battery for a much neater setup (what I did).
The battery I use is similar to this. Note it requires a charger differing to car battery chargers. https://www.jaycar.com.au/12v-9ah-sla-battery/p/SB2487
tl;dr: routers are 12v as is most of the time, using DC > AC > DC is very inefficient when you need 12v DC as is… :P
Edit: For anyone wondering, recently had 4 days with no power… Had to make do with what I had, it worked though.
Thanks. The reason I asked the above question (which I forgot to mention)… The SLA battery in my jump starter needs replacing. Because it so heavy and bulky, I often remove it from the car if I need to carry something. Then I forget to put it back in. So before I go buying another heavy SLA battery, I was wondering if these small lithium ones would run the modem for a comparable time when the power goes out.
The modem plugpack is 12V, 1.5A output, but I didn't have any light to find the correct fitting, lol.
The voltage symbol on the plug pack is a solid line on top, broken line on the bottom - which I thought denoted pulsed DC. Does it? Or just normal DC?
Also digital circuits run on 5 VDC, so I guess the modem has a 5V regulator inside it… So why are most of them powered by 12V?
Think of lithium cells/powerbanks as the same as laptop batteries (as that's exactly what laptop batteries are). The higher quality 6cell batteries are usually rated at 57Wh, use that for reference. (If you have a laptop battery laying around, note it's size and weight)
(Note a powerbank may be slightly larger due to requiring internal safety features, charge circuits, etc, though this won't be any real weight difference)As with the solid/dotted line, it was my understanding this is simply DC? Something like the below?
Edit: Ozbargain is formsttting it weird… Basically it's 3 underscores on the top line then 3 minuses/dashes on the bottom line.
Either way, the difference is only your modem would have a capacitor inside it to smooth the input to DC, though usually such a capacitor is in power bricks these days.
As with 12v, it's more practical I assume… Also it'd suck a fair bit having to have a full blown 10A power cord (think of the thickness of a standard 240v extension cord) to power a 50w switch at 5V, opposed to a thin 12v cord. Beyond that, I'm unsure why.
Edit: If you're fine paying the premium some powerbanks with 12v outputs come with plug adaptors (so it can be easily plugged in without any wiring required), they're usually much expensiver though (high end ones going for in the $100 range)
@dyl: Yeah, I guess there's no way to tell which would be better (last longer powering a 12V modem)… Not without pulling one of the lithium units apart.
Yes, the jump starter I already have is a large Repco unit and has a 12VDC cig. lighter output socket.
I've seen photos of the small lithium jump starters cracked open. And while I know they exaggerate the current they can supply, they still manage to jump start a car. Knowing how small those cells are, I can't get my head around that.
But I was thinking, if they can supply that kind of amps, maybe I could forget about buying a heavy replacement SLA battery for the Repco unit, and get one of these cheaper, lighter, smaller, lithium ones. Then when the power goes out, use it to power the modem for several hours. Maybe the tiny lithium cells in them would last as long as the large heavy SLA, but they're not going to let me open one to read the specs on the lithium cell.
Ah well, thanks anyway.
Why would u want to lug around these massive thungs when smaller battery packs can do the job these days.
