Prolong Travel Mug FAQ

Can I buy the Prolong Travel Mug in stores?

The Prolong Travel Mug is currently available at Peterborough Green-Up, Aylmer Street, Peterborough and in Ottawa at the Ingenium Boutique, located in the Museum of Science and Technology.

Can my Prolong Travel Mug go in the dishwasher?

No, the mug and lid should both be hand-washed with warm water and a mild soap. A bottle brush may be used to properly wash the beverage cavity of the mug.

How do I charge the Prolong Travel Mug to use again?

The Prolong Travel Mug will recharge on it’s own in 12-24 hours. To reuse immediately, fill the cavity with cold water for 1-2 minutes.

What factors influence the mug’s performance?

The Prolong Travel Mug is designed for beverages served at or near 75°C, the average range for over-the-counter hot drinks. Beverages near boiling will take longer to cool to a safe temperature, and will decrease the time your beverage is maintained at the optimal temperature. The addition of milk, cream or other additives that cool the pour temperature below 75°C may likewise shorten the optimal temperature range.

As a tea drinker, my tea needs to be brewed near boiling for best flavour. Will this work with the Prolong Travel Mug?

Beverages at or near the boiling point should be allowed to cool for several minutes before transferring to the Prolong Travel Mug. Teas should be steeped in a separate container, then transferred to the Prolong Mug after the steeping process is completed.
