  We consider Supersymmetric (SUSY) and non-SUSY models of chaotic inflation
based on the simplest power-law potential with exponents n=2 and 4. We propose
a convenient non-minimal coupling to gravity and a non-minimal kinetic term
which ensure, mainly for n=4, inflationary observables favored by the
BICEP2/Keck Array and Planck results. Inflation can be attained for
subplanckian inflaton values with the corresponding effective theories
retaining the perturbative unitarity up to the Planck scale.
