Portable Jump Starter

[emroch]

The Tow Guide/User Manual has this sentence in the jump starting section:

If you're using a portable jump starter, it must maintain a steady voltage between 13 to 16 V at 30 A.

This phrasing sounds like a warning indicating that you need to find a particular type of device to support jump starts. But many portable jump starters seem to be in the hundreds or thousands of amps, well over 30A.

Does R2 require sustained 30A power for some amount of time, which even the big 1000A starters might not be able to do, or is that just a maximum peak rating?

I am specifically looking at the NOCO Boost GB40 to keep as an emergency kit for myself or in case I can help someone else. AI tells me that the NOCO are not specifically rated for EVs and might struggle/fail, though the bigger ones might do better. I don't really want to invest in any of the super big ones though, the GB40 seems like a reasonable size to keep around in the trunk/frunk.

If it's at all like the R1, it will require close to 30 amps for maybe a min or so in order to boot the stone cold dead computers and screens. Those small hand held 1,000 amp jump boxes 100% are out of the question. You need an old school 12V jump pack which has Sealed Led Acid batteries inside.

I carry a small jump box like you posted, but only to help others. I've accepted that I'm not going to self-recover if I get a dead battery. Honestly, if you're concerned about starting a completely dead Rivian battery, you might be better off carrying some old-school jumper cables and relying on an ICE vehicle to help you.
