  In this paper, we investigate the phantom energy accretion onto 3D black hole
formulated in Einstein-Power-Maxwell theory. We have presented the conditions
for critical accretion of phantom energy onto black hole. Further, we discuss
the thermodynamics of phantom energy accreting onto black hole and found that
first law of thermodynamics is easily satisfied while second law and
generalized second law of thermodynamics remain invalid and conditionally
valid, respectively. The results for BTZ black hole can be recovered by taking
Maxwellian contribution equal to zero.
