Portable power for Sky-Watcher Synscan GOTO 8" Dobsonian

[chellaxy (Chelle)]

Hi everyone,

Apologies for another post about portable power but I didn't seem to find what I was looking for on other threads so thought I would ask here:

I have Sky-Watcher synscan on a Dobsonian that requires 12V but I'm not super electrically minded. Would a 12V car jumpstarter work? Why/why not?/Any additional components or modifications necessary?
I just really don't want to have to spend hundreds just on a powerpack!

Specifically considering this model: Repco 12V 800A Sealed AGM Battery Jump Starter - RCJS800.

Thank you in advance for any insight!

Jump starter batteries are designed to supply a lot of current for a very short time. You would be better with a deep cycle AGM or lithium ion. If you really want to use a jump starter, someone in this thread describes using a 1200A model.
