Keurig K-Brew Plus Chill vs Ninja PB051 Single-Serve Coffee Maker

Buy the Ninja if you want one machine that brews both pods and ground coffee, with a built-in frother and large travel-mug sizes. Buy the Keurig K-Brew Plus Chill if you mainly drink iced coffee and want the machine to chill it for you. The Ninja is the more versatile brewer; the Keurig is the more specialized iced-drink machine. Both carry a one-year warranty, and owners of each brand report the usual pod-machine complaints: scale buildup and the need to descale regularly.

  • Choose the Keurig K-Brew Plus Chill if you drink iced coffee often and want a machine that brews and chills in one step, with a 2 L removable tank.
  • Choose the Ninja Single-Serve Pods & Grounds Specialty Coffee Maker if you want both pods and ground coffee, brew styles, a frother and sizes up to 24 oz.

Prices

  • Keurig K-Brew Plus Chill: $170.20 at Amazon (last seen Nov 7)
  • Ninja PB051 Single-Serve Coffee Maker: $89.95 at Amazon (checked today)
  • Difference: the Ninja PB051 Single-Serve Coffee Maker is $80.25 cheaper than the Keurig K-Brew Plus Chill at the latest prices (Nov 7 and Nov 9)

Questions and answers

Which is better for iced coffee?
The Keurig K-Brew Plus Chill, because it chills the coffee itself from an 11.5-cup chill tank. The Ninja has an Over Ice style but you add the ice.
Can the Ninja brew regular ground coffee?
Yes. It comes with a removable brew basket and permanent filter and brews grounds from 6 to 24 oz. The Keurig takes pods only.
Which makes a bigger cup?
The Ninja, up to 24 oz with grounds and 12 oz with pods. The Keurig tops out at 12 oz.
Is the Keurig worth stepping up to for lattes?
No. It has no frother and no concentrate setting. The Ninja's Specialty style and built-in frother are the better fit for milk drinks.
Which is easier to keep clean?
The Ninja has more parts to wash but they are removable, including the frother. The Keurig is simpler day to day but its chill tank needs regular cleaning.
Do both have the same warranty?
Yes, both list a one-year warranty.
