Questions about this item

What does the 12 V cigarette-lighter input limit in practice?

The 12 V socket caps continuous output at roughly 400 W, so appliances above that draw will trip the built-in fuse.

What clearance does the 6.7 x 4.5 x 2.5 inch case need?

Allow at least 6.7 inches length, 4.5 inches width and 2.5 inches height plus space for the 21.65 inch cables to reach the socket.

How is the inverter installed and what step is often missed?

Plug the unit into the cigarette-lighter socket, then switch the inverter on; the step people miss is turning on the inverter’s own power switch after plugging it in.
