Introducing Jül: A Smart Mug for Better Beverages

March 21, 2017

Salt Lake City, UT (Mar 21 2017) — Power Practical, a team of designers and makers of power products for active lifestyles and everyday living, is proud to announce the launch of the Jül: an intelligently designed tumbler that keeps hot beverages at the perfect temperature from the first sip to the last drop.

Announced this week on the popular crowdfunding platform Kickstarter, the team at Power Practical is excited to unveil their latest patent pending innovation, The Jül: A smart self-heating tumbler that keeps your beverage at the ideal temperature through to the last sip. The Jül is powered wirelessly via a USB-connected coaster and actively monitors a beverage to let you know when it’s too cool, too hot, or just right with a subtle indicator light. Temperature adjustments are made with a simple twist of the mug’s base and the Jül’s custom lid design may be switched between three functions: spill-proof seal, drink mode, and a cooling vent to let off steam and refill.

Inspired to create practical solutions to everyday problems, the Jül hits home for the small and often-caffeinated team at Power Practical. Drinks in ordinary mugs and paper cups cool down too quickly, while modern insulated travel mugs can keep a beverage uncomfortably hot for too long. The Jül, on the other hand, delivers steady control in your ideal temperature zone for as long as you need it.

The Jül comes with a stainless steel interior, an elegant minimalist exterior design, and a concave lid for easy sipping without nose-to-lid contact. Thoughtfully designed from top to bottom, the Jül is the ultimate everyday beverage companion so you are never unpleasantly surprised by a scalding or lukewarm drink again.
