Car Jumpstarter for 5.3l Petrol

hi, I'm looking for a jumpstarter for a 5.3l petrol. The old Mechpro 1200amp used to start a 5.7l petrol, but new ones say a 1200 won't cut it. The AA was no help at all. Any advice on what size I need and is there a best time to buy one. (Also any insights on why the new 1200a won't start 5.3l when the old one started 5.7l with a totally flat battery). TIA.


  • Repco are still listing the old mechpro 1800a units on clearance.
    Looks like some stock around the country.…

    Otherwise the projecta units are pretty good.

  • Hi there,

    I would highly recommend this stuff:
    ( pdp_npi=2%40dis%21NZD%21NZ%24%20234.07%21NZ%24%20234.07%21%21%21%21%21%402101f6b816732050639101081e9ac8%2112000030882966420%21btf&_t=pvid%3A285bc46b-3ee1-4d3b-bdc9-01466a5e3552&afTraceInfo=1005004884065035__msite__c_ppc_item_bridge__xxxxxx__1673205064&spm=a2g0n.ppclist.product.0&gatewayAdapt=Pc2Msite)

    but the price really bites this year. πŸ€¦πŸ»β€β™‚οΈ

    U can try to surf the Web, maybe it is still available somewhere on NZ's websites.

    For instance:
    "70mai jump starter max 18000mah buy online nz"

    I purchased one last year (by mighty ape for β‰ˆ190$) and I am still very pleased with its performance. πŸ‘πŸ» Very helpful for my Toyota Harrier G350 (3.5l, petrol)πŸ‘πŸ»

    Cheers! πŸ‘‹πŸ»

  • Probably slightly more expensive, but far more portable, you can get something like this:…

    I was very surprised at how well they perform, I had a tractor with a completely dead battery that wouldn't start from a jumpstart from a ute or a 2000amp jumper unit like that Mechpro, but it started easily from the "hulk". It still showed 80% charge after one jump too.
