Ember Mug 2

If you hate reheating half-drunk coffee, this is the sort of gadget that fixes that daily annoyance; the Ember Mug 2 is a rechargeable, app-controlled heated mug that holds 14 oz (414 ml) and keeps a drink at a precise temperature so your first sip tastes the same as your last. It’s aimed at people who work at a desk, move between meetings and want one-cup convenience without constant trips to the microwave. ## What makes it worth it Ember’s claims line up with hands-on testing and the product pages: you can set an exact drinking temperature between roughly 120°F–145°F (50°C–62.5°C) and the 14 oz Mug 2 will maintain that temperature for up to 80 minutes on battery or indefinitely when left on the included charging coaster. The Ember app adds real value — you can pick a precise °F/°C, save presets, receive firmware updates and change the LED colour — features reviewers repeatedly highlight as best-in-class compared with basic heated pads or passive insulated mugs. The mug also uses motion and thermal sensors to wake when you pour and sleep when idle, and Ember publishes an IPX7 spec that lets you hand wash and briefly submerge the body for cleaning. ## Where it falls short The battery life (about 80 minutes for the 14 oz model) is better than some earlier smart mugs but still means you’ll rely on the coaster for all-day heat, and the mug is hand-wash-only which makes care a little more fussy than a dishwasher-safe insulated cup. If you want a reliably hot cup at your desk and don’t need a leakproof travel solution, buy this; if you need long off-dock thermal performance or a fully dishwasher-safe travel mug, look elsewhere.
