We study the requirement on the jet power in the conventional p-$\gamma$models (photopion production and Bethe-Heitler pair production) for TeV BL Lacobjects. We select a sample of TeV BL Lac objects whose SEDs are difficult tobe explained by the one-zone leptonic model. Based on the relation between thep-$\gamma$ interaction efficiency and the opacity of $\gamma\gamma$ absorption,we find that the detection of TeV emission poses upper limits on the p-$\gamma$interaction efficiencies in these sources and hence minimum jet powers can bederived accordingly. We find that the obtained minimum jet powers exceed theEddington luminosity of the supermassive black holes. Implications for theaccretion mode of the supermassive black hole in these BL Lac objects and theorigin of their TeV emissions are discussed.
