Hi
thanks for the reply. I should have been a bit clearer.
the main purpose for this would be to run the scope. The charger would only be used for the iPad as a back up as the iPad would be fully charged prior to using and the dslr uses its own separate battery.
sorry I’m a complete novice with these power chargers and from what I can tell it’s more to do with the ampage output?
I saw this one where it says “6a max” on the 12v outlet would this be better?
