Ninja PREPi PN301 vs PN351: Specs and Price

Ninja launched the PREPi prep-and-store system in the US on October 2, 2026, as two closely related kits that share the same motor and bowls and diverge mainly on whether dicing is included.

Both configurations put chopping, slicing, shredding, puree work, and crinkle cuts into one compact base, then let you serve or fridge leftovers in the same bowl with a lid. The pitch is fewer knives, fewer boards, and fewer transfer dishes for everyday meal prep rather than a full-size food processor tower.

What PN301 and PN351 share

Under the hood, SharkNinja rates both models at a 500-watt motor in a space-saving chassis. Each kit includes a motor base, 5-cup and 7-cup PREPi bowls, two storage lids, a Chop and Puree Blade, a reversible Slice and Shred Disc, and a Crinkle Disc. A three-part feed chute is meant to handle different ingredient sizes without forcing everything through one opening.

Color is part of the shopping decision. PN301 ships in Midnight Blue and Mango, Pink Peppercorn, Stone and Moss, or Onyx and Apricot. PN351 is listed in Copper and Teal on SharkNinja.com, while Amazon also shows a black PN351 bundle with the dicing kit. Dimensions land around 9.3 by 9.3 by 10 inches with a roughly 31.5-inch cord, so this is countertop kit scale, not a hidden under-cabinet appliance.

Where the dicing kit changes the deal

PN301 is the 5-in-1 path: chop, puree, slice, shred, and crinkle. Dicing is optional through a separately sold Dicing Kit that SharkNinja lists at $59.99 on the same storefront. PN351 is the 6-in-1 configuration that includes that dicing kit from the start, so onion cubes, salsa prep, and salad dice do not require a second checkout.

SharkNinja also lists a PN301B1 blue bundle that pairs the five-function unit with the dicing kit at the same $229.99 tier as PN351. If you want dicing and prefer Midnight Blue and Mango over Copper and Teal, that bundle is the color workaround rather than a third machine design. Kitchen shoppers who already track single-purpose brewing gear may also care about our note on the Keurig Alta Brewer, another compact countertop system aimed at cutting daily friction.

Who should pick which PREPi

Choose PN301 if most of your prep is sauces, shreds, slices, and crinkle fries, and you are fine buying the dicing kit later only if you miss it. Choose PN351 (or the PN301B1 bundle) if diced vegetables show up in weekly cooking and you would rather pay once than piece the accessory later. The roughly $50 gap is basically the dicing story; motor power, bowl sizes, and the shared disc set stay the same.

Limits follow from the design. This is not a massive batch processor for holiday catering, and the feed chute still asks you to cut large produce down to fit. Claims about cutting prep time and dishes come from SharkNinja’s launch messaging; we have not run a hands-on timing test. Treat the system as a weekday sous chef for small households, not a replacement for a full knife kit when you need irregular rustic cuts.

Bottom line for US shoppers

On SharkNinja.com today, the PN301 lists at $179.99 and the dicing PN351 at $229.99, matching the October 2 launch figures of $179 and $229. Both pages showed the units as available to buy. For the base five-function kit, start at the Ninja PREPi PN301 product page and compare the PN351 listing if regular dicing is non-negotiable.
