Ninja Sip Perfect Travel Mug - Grey

The HeatStore Technology absorbs excess heat from scorching hot drinks, bringing them down to a comfortably sippable temperature within minutes. It then slowly releases this stored heat back into your drink, helping to maintain it within the ideal temperature zone for an extended period.

The stainless steel mug body is dishwasher safe for convenient cleaning. However, to prolong the life and maintain the integrity of the LockLeak lid, it is recommended to hand wash the lid with warm, soapy water.

The Ninja Sip Perfect Travel Mug has a capacity of 400ml.

Yes, while designed with hot drinks in mind, this stainless steel tumbler is also perfectly suitable for keeping cold drinks cool on the go.

The mug comes with a 2-year guarantee by default. To extend this to a full 5 years, you must register your product with Ninja (UK & ROI only) after purchase.

To prevent leaks, always make sure the LockLeak lid is securely closed and the locking latch is fully engaged. Do not fill the mug past the maximum capacity line indicated inside, as overfilling can lead to spills.

Yes, the Ninja Sip Perfect Travel Mug features an ergonomic lid with a press-button rocker cap that can be easily opened or closed with one hand, ideal for on-the-go use.

For faster cooling of initial very hot drinks, ensure the HeatStore technology has enough time (a few minutes). To maintain warmth longer, try preheating the mug with hot water for a few minutes before adding your beverage. For cold drinks, adding ice can speed up cooling.

Ensure the LockLeak lid is securely closed and the locking latch is fully engaged. Check that you have not overfilled the mug past its maximum capacity line, as this can cause spills when the lid is attached. Inspect the silicone seals on the lid for any damage or misalignment.

The lid is designed for deep cleaning. Locate the lock on the underside of the lid, rotate it to the open position, and then remove the rocker cap. Lift the lock latch to access all internal areas for cleaning. Hand wash all disassembled components with warm, soapy water and allow them to dry completely before reassembling.

Ensure the lid components are clean and free of any dried residue, especially around the button and rocker cap mechanism. A thorough deep clean of the lid may resolve this. If the issue persists after cleaning, ensure the lid is correctly assembled.
