Noco 400amp jump starter powerful enough?

I street park and today my car wasn't having any of it. Yesterday it started fine.

I see noco has several jump starters starting at 400amp. Is the 400amp enough or should I be going to at least 1000amp?

I have a 1200 amp booster pack from cdn tire (motomaster)that I am very happy with.
I think I paid about $100 for it when it was on sale about a year ago.
400amp may not cut it when you need it most.

I also have the 1200 and it works well.

As a stop gap you can just remove the battery, take in indoors and charge it. The fully changed warm battery should start the engine without any issues.

BTDT. For a week I had to bring in the battery every night. A few winters ago when we had a long cold snap every supplier was out of C-94R's & had to wait for one to come in.
