Can anyone recommend a jump starter pack? Basically a portable battery pack with jumper leads to start a car if the battery is too low.

Needs to be able to start at least an RB25DET.

They tend to look something like the below.

I have a Unigear A6 jump starter pack bought from Justjap. They don't sell it anymore. Likely because it doesn't actually work. It was advertised to be good for <= 4l engines but wasn't able to start a ~2008 4 cylinder BMW when we tried it. So I very much doubt it'll do any good on an RB.

Now I'm looking for something that actually works.

Thanks!

I bought the Noco GB40 (1000A) forever ago but it just lacked enough power to start our X5 (diesel 3L straight 6) but could do a few good attempts at my 335i. 

Then I upgraded recently to the GB50 which is 1500 Amp. Its proper capable of starting either of my cars now. The little one will be fine in my daughters XV I think though so not totally wasted.

I'm surprised yours doesn't work if it is truly 2000 Amp!

I've got an older version of this supercheap one https://www.supercheapauto.com.au/p/sca-sca-compact-jump-starter-12v-1200a-6-cylinder/631666.html?cgid=SCA01060201

I've kept it in my car for like 5 years and jumpstarted plenty of gtrs at events. Only thing I don't like about it is that the leads don't detach from the pack so the wires always have tension on them in the stored position. It gets about 3 jumpstarts per charge or I plug it in to charge like every 6 months

Hah, you make it sound like it gets a lot of use in your household. BMW life, eh? ;)

I very much like the sound of this one. Especially the supposed 1 year battery life. Might grab one at the next opportunity.

Thanks for the tip!

Woops, thought the pic was of your model but it doesn't appear to be. Ignore my last sentence.

Yeah nah, mine is like this.

It's really not very good.

- It's round which makes it awkward to place in engine bay without rolling around

- The charge doesn't hold for very long and need to recharge every few months

Might work for self defense though as it has some serious heft to it. And I guess can use it as a torch and pretend it's a huge Maglite.

Thanks for the detailed review Jairek! Much appreciated. This has definitely proven itself on RBs then. Also quite affordable.

I'll have a think about it. Though I'm leaning towards the one that Prank mentioned. It has a bit more oomph, longer battery life and is actually a bit smaller in size. Not that the latter comes as much of a concern in the wagon.

Do you want to borrow it? I don't mind sending it to you. It doesn't get *that* much use! 🙄

Since i always have cars with flat batteries, I use one of these, expensive thou at 880rrp

In my experience pretty much any of those square ones like you posted in the first fill start a skyline as long as the jump pack is properly charged, they are a simple, low compression engine. Just remember to let the fuel pump prime at ON  for 3 seconds before you hit start

Duncan! Why do you do this to me? I'm a sucker for buying good gear that is way more capable than my actual use case requires. You have the excuse of basically being a Nissan fleet manager :D

Their slightly lower spec emergency charger looks really promising:
https://www.projecta.com.au/products/IS1400/12v-1400a-prof--jmpstrtr

I very much like that it shows the current car battery voltage when it's connected. And their rapid recharge mechanism to bring the jump starter power back up by leaving it connected for a while after jump starting the car. And they have a pretty detailed spec sheet with their chargers.

Do I need a jump starter capable of starting 7l petrol and 5l diesel engines? Hell no.
Do I want one? You bet I do.
Am I going to spend $500 on a charger that best case I'm never actually going to use? It's very much starting to look like it.


/edit: Looks like one can get this one for $350 at repco. So actually not too bad.

All good, but thanks for the offer Christian! Not using it is the best case scenario. For me it's just something to have in the car for peace of mind.

Yeah, they're a difficult thing to take for a test run unless you routinely and habitually suffer flat batteries already. If I bought some for my girls (for example), I'd be damn sure to find them dead flat in the spare wheel well having been forgotten about and never used for 2+ years.

I keep jumper cables. They don't go flat.

+1 for jumper leads (with surge protection) for "in the boot essentials"

Also, if parked up, I always connect my 7 stage trickle charger thingie, whether the battery is connected in the car, or if the battery is sitting on a bench in the shed

All the electronical thingies in modern cars put a slow but steady drain on batteries when parked up with the battery connected 

The little battery in the Harley would drain out in about 7 days because of this

I also run up our cars that are daily driven on the trickle charger every few months, it apparently 'de-sulfers" the batteries or something (electronical black magic) and makes them last longer

The older batteries do sit in the de-sulfer zone for a while, but they do keep on working fast and hard on start up

The OEM battery in the Mrs Mitsubishi ASX is around 10 years old, parked up outside all year, and does alot of short drives, I truly believe it has only lasted this long because the occasional runs up on the charger

A good trickle charger is money well spent, even if you only let it run through all of its cycles occasionally

I ended up getting the Projecta 1400A jump charger. Repco had it at 20% off and it came to $350. Also a set of jumper leads with surge protection just to be sure.

It seems a solid piece of kit. Comes with a case, a USB-A to USB-C cord and a cigarette plug charger. No wall charger though. It shows the battery voltage when you connect it which is neat. So far it inspires confidence. Will report back on how it holds up when I actually get to use it one day.

Ordered myself a gooloo , so far so good. 
$180 - https://gooloo.com.au/products/gt4000s?variant=44378290651382

That looks like really good value for money. Plenty of power to start a Nissan Unimog :D

Looks like Noco did well in the testing in the video as well. Only skipped through the video but he has some slides with results at the end.

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
