I just ordered this for use with my Little Pilot VR goggles. It needs 5V however my goggles are powered by a 2S battery (7.4V). Obviously the solution is to use a step-down converter, but i am too impatient to order from China again, and local suppliers want to charge me close to $10 to post one to me.
However i was thinking that a 12V cigarette lighter socket USB charger should contain a stepdown converter right? They are like $1, so would that work?
