Description
The Zojirushi stainless steel mug (model SM-KHE48) is a 16 oz vacuum-insulated travel mug from a Japanese brand that has been making insulated bottles for more than a century. It is slim, light and built for people who want coffee or tea to stay hot through a long morning at the desk or on the road.
What Sets the Zojirushi Stainless Steel Mug Apart
Zojirushi rates the mug at about 187°F after one hour and 154°F after six hours, starting from very hot water, and about 48°F after six hours for cold drinks. The interior is 18/8 stainless steel with the brand’s SlickSteel finish, which is designed to resist corrosion and repel stains so coffee flavors don’t linger.
A flip-open lid has a safety lock to keep it from opening by accident in a bag, and the compact body fits many car cup holders. Wirecutter’s travel mug guide names the Zojirushi as a top choice for heat retention, and Zojirushi backs the vacuum insulation with a five-year warranty.
Who It’s For
Remote workers who sip slowly between meetings, commuters who want a mug that won’t spill in a backpack, travelers who carry their own coffee through airports, and anyone shopping for a practical holiday gift under $50.
Pros
- Strong heat retention rated by the maker at six hours
- Locking flip lid for bags and commutes
- Stain-resistant SlickSteel interior
- Five-year warranty on the vacuum insulation
Cons
- Lid has several parts to wash
- Some users find the lid latch sits close to the chin when drinking
- Hand wash only, which takes a bit more care
Buying Tip
Preheat the mug with hot water for a minute before filling it, which helps drinks stay hot longer. The same mug comes in several colors and a 12 oz size, so pick the 16 oz if you drink a full pour of coffee in one go.
