I'm looking to buy one of these "Portable Jump starters"

Kick that that SLA battery on down the road. Optimas also will last twice as long. Don’t even screw with that gold top another second. Oh and it’s 30 + pounds lighter too.

This is a very compact pack with a nice carrying bag. I used it to start (981 Spyder) multiple times. The car fired up every single time at the first crank. Highly recommended. The battery pack now sits behind the seat for emergency use.
That one is unavailable.
But this looks similar.

I guess a key feature is the 800 amps, faster than 400. Would charge a car battery quicker I assume.
