I've got a jumpstarter from Super Cheap - it's pretty new but I've lost the charger.

The charger doesn't look like a standard AC wall adapter type charger so I'm sort of stuck.

Is it possible to attach a normal car battery charger to the two leads on the jumpstarter; positive to positive, negative to negative, and charge the jumpstarter that way? Like a slow, reverse charge?

Really need some details like make/model, maybe a picture.

Have you tried Super Cheap to see if a charger is available?

It might work a few times but you could damage the battery. The battery in that pack is an AGM battery which shouldn't really be charged with a wet cell charger, it will probably get overcharged. I'd look for a 12V 1A adaptor and then add a matching plug to fit the pack and let the pack's charge circuits handle the charging. You could even make up a cigarette lighter plug and cable and charge it from your car. I'm not sure, but that odd plug/socket on the pack could be this one: https://www.jaycar.co.nz/2-pin-bullet-type-plug-socket/p/PP2034

The original charger was probably 13-14V or so I'm guessing, so the closer you can get to that the better, but don't go too much higher.

According to the User Manual you can buy replacement chargers from SCA. Just go to the nearest SCA shop.
There's a link to the manual on the page you linked.

The manual also says any SCA branded battery charger will work. Just needs the correct connector.

One of theses will do the job. https://www.supercheapauto.co.nz/p/sca-sca-12v-2.5-amp-3-stage-battery-charger/577071.html

In fact I'd say any 12 volt battery charger connected to the charging terminals will work. Just a matter of having a suitable connector. Connecting to the jump start leads may work too but I suspect the reverse polarity protection will prevent this method from working.

Sure
get it wrong & you could burn your house down .
Looks like its leadacid, not lithium batts , so risk may be minimal .

Why not just buy the correct charger .
Or open it up, remove the batt & charge it normally . At least open & see how its connected . You might be able to put a car batt charger on it
If supercheap cant supply spare charger for this , then questions need to be asked as to why not.

I use a SCA 7 stage charger that says "Automatic battery chemistry selection administers correct charging profile for GEL, Lead Acid, AGM, and Calcium". Doesn't seem to have hurt things so far, though I usually have them solar charged.

I've been in a similar position, except rather than loose the charger, it actually broke. I've got an older SCA jumpstarter pack to what the OP linked earlier - more like this, but I assume that the charger should be still the same/similar?

When I had a hunt for a replacement charger, believe it or not, Repco actually sold a replacement charger.. It was the exact same charger - same Chinese manufacturer and input/output etc..

Unfortunately for me, the replacement charger wouldn't completely charge my jumpstarter pack as I'd left it in an empty state for too long.. and reading the manual, that's not good for it. However, getting desperate, I hooked up an actual car battery charger to 'reverse charge' and that seemed to work for one jump start - then the pack drained away super fast...
