Note: I have an Enertia +, not a base Enertia, so my values may be different.
I see a nominal 9 amps, but I think I see spikes to 11. I believe a 15A circuit is recommended. If we assume they made the smart call and pad 20% overhead, that means they expect it to run at 12A. Personally, I'd spend a few bucks extra on the shortest cord with a minimum of 15A rating.
