7940.
Also, I see there is a newer AIR-PWRINJ3 that's out. The AIR-PWRINJ2 has been EOL'd.
My 7970 is only drawing 10.3W with a max of 15.4W. That's less than the 16W the AIR-PWRINJ2 will offer.
Here are a couple examples from an actual POE switch.
Power Device Class Max
(Watts)
- ------- ------------------- ----- ----
12.2 AIR-AP1131AG-A-K9 3 15.4
10.3 IP Phone 7970 3 15.4
6.3 IP Phone 7940 n/a 15.4
