Will the Anker 521 PowerHouse run a portable ac (small)?

No — the portable ac (small) needs more power than this unit delivers

It draws about 900W, but the 521 PowerHouse only outputs 200W continuously — so it won't start, or it will overload and shut off.

Because the portable ac (small) needs more continuous power than this unit can deliver, a runtime figure doesn't really apply — you'd need a higher-output station. See stronger options below, or the sizing calculator to find one that fits.
