How quickly does it warm up?

Most of our heaters and warmers give noticeable heat within one to two minutes. Exact times are listed in the product description.

Is it safe to leave running?

Our heaters are designed with safety features such as overheat protection, and many also have tip-over protection — check the product description for the exact features. Never cover a heater and always follow the instructions.

Will it work with US outlets and car sockets?

Plug-in products come with a US-compatible plug or adapter. Car products use the standard 12V outlet found in US cars.

How much energy does it use?

Because you only heat the space or person you need, you often use far less energy than heating the whole house. The wattage is shown on every product page.

How can I track my order?
