Which is better for a family of four?

The Instant Vortex Plus. Its 6-quart dual-zone basket holds more and lets you cook two foods at different settings at once. The Cosori's 5.8-quart single basket is rated for 3 to 5 people.

Which one is better for dehydrating?

The Instant. It goes down to 95 F and has a dedicated dehydrate program. The Cosori stops at 170 F, which is too hot for jerky or dried fruit.

Is the Cosori worth the extra dollar?

Only if you want the touchscreen and saved presets. At $90.95 versus $89.95 as of November 8, 2026, the price gap is trivial; pick on features, not cost.

Which has better controls?

The Cosori, if you like touchscreens. You can save custom time and temperature settings and toggle the shake reminder. The Instant uses a dial, which is simpler but less precise.

Do both use the same power?

Yes. Both draw 1700 W at 120V and top out at 400 F, so they heat and crisp similarly. The difference is basket size and controls, not cooking power.

Which is cheaper over time?

The Cosori has dipped lower: $56.00 on November 2, 2026, versus the Instant's $87.99 low on the same date. Check price history before buying either.
