The VSITOO S3 Ultra is a 20 oz self-heated smart mug that holds coffee or tea between 120°F and 150°F. It uses an auto-sensing system to keep the drink warm without manual adjustment. The 20 oz capacity is larger than most heated mugs, which usually top out around 10 to 14 oz, so it suits people who pour big cups and sip slowly. Like other battery-heated mugs, it needs charging and adds weight compared with a plain ceramic mug.
