What's the maximum capacity of the Fresh Juice Blender?
Answer: The Fresh Juice Blender has a total cup capacity of 16 oz (473 ml). The recommended maximum fill line is 14 oz (414 ml), which leaves about 60 ml of headroom for ingredients to move and create the proper blending vortex. Overfilling past the max line causes poor blending and can leak under the lid.
The detailed answer
Every portable blender lists two capacities: total cup volume and recommended maximum fill. These are different on purpose, and understanding why matters for how well your smoothie turns out.
Total cup volume is 16 fluid ounces (473 ml, or 0.473 liters). That is what the cup can physically hold all the way to the brim. In real use, you never fill a blender to the brim of any blender, including a Vitamix, because the ingredients need space to circulate.
Recommended maximum fill is 14 fluid ounces (414 ml). This is the line you will find molded into the side of the Tritan cup. It is 2 oz below the brim, which is the amount of headroom the engineers calculated based on the blade geometry and the typical density of smoothie ingredients. With 2 oz of headroom, the vortex can form properly and ingredients cycle through the blades efficiently.
If you fill above the 14 oz line, two things happen. First, the top of the smoothie never reaches the blades, so you get chunks at the top and over-blended puree at the bottom. Second, pressure from the spinning vortex pushes liquid up past the lid gasket, which can leak.
For reference, 14 oz is about the size of a large Starbucks grande drink or a standard protein shake. That is enough smoothie for one generous serving. If you want more, blend two cycles, or pour cycle one into a bottle and blend cycle two.
Some customers ask about a larger cup. The 16 oz size is deliberate. It is the sweet spot where a 7.4 Wh battery can deliver strong blending performance without taking so long that the motor overheats. A 20 or 24 oz portable blender would require a significantly bigger battery, which would push the unit over the 100 Wh airline carry-on limit and make it too heavy and bulky to be truly portable. The Fresh Juice is designed to be the maximum useful blender that is still pocket-sized and travel-legal.
Dimensions: the cup is 88 mm diameter by 225 mm tall with the base attached. Empty weight is 510 grams (1.12 lb). That fits in most gym bag side pockets and most cupholders.

What is the minimum amount I can blend?
Around 100 ml (3.5 oz) is the minimum for the blades to engage properly. Below that the ingredients sit below the blade zone.
Can I blend a single-serving protein shake?
Yes. A typical protein shake (8 to 12 oz) is well within the 14 oz max fill line and blends in under 15 seconds.
How many smoothies per cup?
One 14 oz smoothie per cycle. The cup is designed as a single-serving personal blender.
