CREATE TABLE table_4265 ("Material" CLOB, "Type" CLOB, "Geometry" CLOB, "Output voltage" CLOB, "Output power" CLOB, "Synthesis" CLOB, "Researched at" CLOB)

What is the output power for the v p =~3 mv output voltage?
SELECT "Output power" FROM table_4265 WHERE "Output voltage" = 'V P =~3 mV'
SELECT "Output power" FROM "table_4265" WHERE "Output voltage" = 'V P =~3 mV'
