My wife has an electric yarn spinner which operates from 120v outlet and converts to a 12v 1.2 amp(max)DC power. Per the manufacturer, amps are typically running at .5.
I want to provide a power source without the required need for a power cord. Therefore, the obvious solution is battery power. The confusion lies with the amps. I know all AAA, AA, C and D size battery outputs are
1.5 v (1.2 running) and each one puts out different amps. As I understand it, amp output for AAA is roughly 1, AA is 2, C is 4 and D is- Therefore, I assume the AA, C and D are not needed due to the higher amps since I will need at least 8 batteries to achieve 12 volts, unless I go with a 9 volt plus two AAAs, which seems more logical since a 9v puts out .5 amps. Anyway, this is the confusing part as what I need and whether to connect in serial or parallel.
Can anyone provide some enlightenment for my lack of battery knowledge?
Thank you
