Battery Jump box recommendation

I use an AGM battery with leads connected to directly to it. It's motorcycle battery size. Nothing to fail but the battery. I charge it every couple months on the bench. You've got to insulate the big alligator clamps for storage. Goes in a cordura case in the back and doesn't take much space. Never had much luck with the integrated compressors. I have one that works, but it takes way too long. I'd guess 45 minutes to fill a 33" tire, but not sure because the battery has always died during the process. I just carry a bicycle pump now as a backup to my onboard air.

Used one of these for years. Works good and reliable.

Running this now, it's really not that much faster than the 450P
