The Litflask is a multi-functional 20oz unit that combines a vacuum-insulated water bottle with a Bluetooth speaker and an LED light. The body is made of 304-grade stainless steel with a powder-coat finish that provides a secure, non-slip grip. The speaker is housed in a detachable base made of ABS and TPU. This design allows the bottle to serve as a 12-hour thermal flask while also acting as a portable media device for outdoor gatherings or gym sessions.
Because the electronic components are located at the bottom, the bottle has a bottom-heavy weight distribution that helps prevent tipping. However, the speaker housing is a sensitive area; while it is designed for portability, drops on hard surfaces can impact the electronic components. It is important to ensure the charging port seals are fully closed to prevent moisture ingress. Thermal performance is focused on the steel chassis, though users should note that very hot liquids can affect the battery life of the attached module over time.
- The BPA-free construction is verified across the materials used in the vessel.
- The screw-on electronic base provides a thermal bridge that users should be aware of when keeping drinks hot for extended periods.
- Mix-and-match color options allow for personalization of the flask body and base.
If you are looking for a bottle that prioritizes high-volume hydration without the integrated electronics, the Aquafit 64 oz jug is a practical alternative.
