What the Nextmug Is

The Nextmug is a battery-powered, self-heating 14 oz mug that keeps coffee at one of three set temperatures, Warm, Hot, or Piping, instead of letting it slide toward room temperature. Charge it on its coaster, pick a setting, and the mug does the rest.

What Touches Your Coffee

The inner vessel your coffee sits in is stainless steel with a ceramic coating, so the liquid rests against ceramic and steel, not plastic. The exterior housing that contains the battery and electronics is plastic, and so is the drink-through lid. If you sip through the lid, your coffee passes plastic on the way out; drink with the lid off and the path is ceramic-coated steel to your lips.

The Plastic-Free Verdict

Not fully plastic free, but better where it counts: the hot liquid spends its time against a ceramic-coated steel interior rather than a plastic tank or liner. The lid is the weak point, and it is optional. We rate the Nextmug a solid pick for keeping coffee hot without a plastic reservoir, with the lid-off habit recommended. People find this page searching the long Amazon listing name; this is that mug, reviewed for what actually touches your drink.
