I think the latin should be "Ego possum habere." Potest and Habet are third person singular, "he can", "he has". Possum is first person, "I can", and you usually use the infinitive, habere, to complete the sentence - "I am able to have", or "I can has" in lolspeak :p
You don't typically use ego in latin, since the verb already shows that it is first person, but not many people may know that.
