The AstroAI S8 is a compact jump starter that has repeatedly handled everyday dead batteries, from V6 Toyotas and a Silverado to box trucks with up to 6.0 liter V8s. It is light and easy to keep in the car, and it can even revive batteries that a regular charger will not detect. The boost button sometimes helps with stubborn starts, but there are also failures on a Mercedes Sprinter and a Prius. A practical budget pick if you want a small emergency starter with real-world range.

I bought one and it failed, plugged it in to charge and pressed the boost button, it turned itself off after 2 seconds, not allowing enough time to get in the car and start it. I sent them an email and they sent me out another one, well worth $19.
I do that often just for a free second one, Yes my morals are lackin

Same deal monthly by SD Staff
Search "astroai s8"

title seems incorrect, specs read 8000 milliamp_hours
I don't know what the real specs are, but I've used mine to start up to 6.0 V8s in box trucks. This is the lightest and least "fancy" of the few jump starters I've owned, but it just works.

These are also great if u need to charge a dead battery and the charger won't see the battery as it is totally dead. Have revived a few with this...
