There’s a blender hidden inside this insulated travel cup

Nutribullet’s new Flip incorporates a blender into an insulated stainless steel tumbler that looks no larger than a typical travel mug. If you don’t have enough time in the morning to blend your breakfast, the rechargeable Flip works anywhere you don’t mind making a bit of noise. (Maybe skip the crowded subway.)

The $99.99 Flip isn’t Nutribullet’s first single-serve blender, nor is it the company’s first rechargeable one. What sets it apart from past offerings is that the blender part — including blades, an 11.1-volt electric motor, and a rechargeable battery — are all incorporated into the Flip’s lid, instead of into a removable base that gets left behind. We’ve seen that idea before in the powerful Cruz BlenderCap, which costs $149.

On a full charge, the Nutribullet Flip can run a 30-second blend cycle over 14 times before it needs to be plugged back in via a USB-C charging cable. Seven minutes isn’t a lot of time but should be sufficient for blending up a drinkable breakfast or maybe lunch later in the day. The Cruz, meanwhile, gave us a small shake each day for a week.

You can fill the 20-ounce tumbler with whatever ingredients you want. Nutribullet claims the Flip’s motor is powerful enough to blend ice, fresh ingredients, and “most” frozen fruits. But it also warns against using heated ingredients, as they can cause pressure to build up inside that could result in the lid forcefully opening or completely separating from the tumbler.

When filled, the lid is then attached to the insulated tumbler, and the whole thing is inverted before blending so the contents fall onto the chopping blades. It’s also worth pointing out that the Flip weighs 3.45 pounds on its own. A 20-ounce Yeti mug, for comparison, is just over a pound. Adding ice and frozen fruit is going to give you a real workout when carrying this around.

Once complete, the lid can be left on and used for pouring or drinking. The best feature is that when the Flip is empty it can be easily cleaned by filling it with soap and water and then running a single blend cycle. What you don’t want to do is submerge the Flip or stick it in the dishwasher, as that USB-C port is not waterproof.
