Want to make margaritas on the go? Then you might want to check out the new small form factor blender unveiled last week at CES by a company called Cruz.

The Cruz BlenderCap is a new portable blender that has it all in the name: It’s a bottle cap with a blender built in. The product was developed by two former Apple employees, Dakota Adams and Matthew Moore, on the side while they set up a battery factory in China for Apple. The two eventually left their day jobs and went full-time on BlenderCap a year ago.

The BlenderCap’s strength is – perhaps not surprisingly, given the former day jobs of its creators – its battery technology. The blender uses what the company describes as a ‘next-generation electric vehicle Cell-to-Pack battery architecture’, which provides a half horsepower of power.

“You can blend an entire Costco bag of ice and fill an entire Home Depot bucket with margaritas on a single charge,” Adams told The Spoon at CES. According to Adams, the BlenderCap will work with almost any vacuum-plated bottle like a Hydroflask or Thermoflask.

The BlenderCap will start shipping next month from Shanghai, where the two founders leased manufacturing space and are making 6 thousand BlenderCaps in its first production run.

“We’re leasing factory space at a really high-end manufacturer in Shanghai, and we own all the equipment and the robots building this,” Adams told Techcrunch. “So we actually have on our assembly line — we designed the entire assembly line — and we’ve got more robots than people putting this together. It’s crazy. There are glue dispensing robots, automatic screw dispensers. It’s beautiful.”

The BlenderCap is available for preorder for $129 from the company’s website.
