The cup is the whole idea here. It's 20 ounces of insulated stainless steel, and nutribullet rates it to hold a cold blend for up to 24 hours — a claim that sounds like marketing until you're the one drinking a smoothie at two in the afternoon that was blended at seven in the morning. Nothing else in this group is insulated, and that turns out to be the difference between a smoothie and warm fruit soup.
We made the Flip our default because it's the one whose numbers we could plan around. The 11.1V motor and a stated 14-plus 30-second blends per charge, topped up over USB-C, cover a week of weekday smoothies on a cable you already own. It also ships with the parts that make the routine work: a blade cover, a second lid with a carry handle, and steel straws. Unscrew the blade, cap the cup, walk out — no pouring, no second container.
Thick, low-liquid loads are where it gets fussy. Ice and most frozen fruit come out smooth; pack the cup with frozen berries and barely any liquid and it stalls, so keep the ratio loose and shake between cycles. Cleaning has a wrinkle too. The tumbler's interior ridges hold onto seeds, and while a soap-and-water blend cycle does most of the work, the blade assembly still wants a rinse under the tap.
What We Like
- Insulated steel cup keeps a blend cold for hours
- 14+ 30-second blends per charge over USB-C
- Blade cover and spare handled lid make it a travel cup
Worth Noting
- Stalls on thick frozen loads with little liquid
- Interior ridges hold seeds and take extra rinsing
We tell anyone whose smoothie leaves the house to buy this one: the insulated cup and the stated charge per cycle are the two things that make a carried drink work.
