About This Project

STELLR combines a matte-black aluminum alloy flask, a 2,500mAh integrated battery, and a hidden storage compartment into a single portable device. It uses standard USB-C for recharging and USB-A to charge your phone, with a stainless-steel interior and captive hinge cap to prevent loss. Designed for nights out, travel, and daily use, it aims to replace separate flasks, power banks, and plastic containers. The project seeks funding to begin production, with planned delivery in July 2027 and a retail price of $89.

Key Highlights

▸ Integrated 2,500mAh charger and flask in one durable matte-black device.

 ▸ Hidden storage compartment keeps small essentials secure and always with you. 

 ▸ Built from aluminum alloy and stainless steel for long-lasting, reusable use.

Risks & Challenges

The main risks involve precision manufacturing to combine liquid-safe electronics, obtaining lithium battery safety certifications, and adhering to the production timeline affected by tooling and factory schedules (including Chinese New Year shutdown). International shipping may incur duties or tariffs beyond our control, and delivery estimates could shift if funding stages delay. We mitigate these by working with an experienced manufacturer, building compliance into the plan, and providing regular updates.
