Ember Mug 2

Yes, a £130 mug sounds indulgent — if you work at a desk and sip slowly, the Ember Mug 2 keeps every sip at the exact temperature you set with its app and a submersible, scratch‑resistant finish.

If you often heat a cup only to walk away and come back to tepid coffee, this smart heated mug keeps a single cup at a chosen temperature so you don’t have to reheat. It’s aimed at desk workers and slow sippers who want repeatable, drinkable coffee or tea without the microwave and who value smartphone control and precision. ## What makes it worth it Ember’s Mug 2 maintains a set temperature between 120°F and 145°F (the company and multiple reviews report precise control and ±1°F accuracy in real use), giving you repeatable, exactly-warm sips rather than a hot first sip and a cold finish. The mug is app-controlled so you can set temperature, create presets and get notifications from your phone, and it ships with a redesigned charging coaster that lets the mug run for roughly 80–90 minutes on battery alone or remain heated all day when left on the coaster. Build-wise it uses stainless steel with a reinforced ceramic coating that’s safe to hand wash, and it’s rated IPX7 (submersible up to 1 metre), which most competing smart mugs don’t offer. ## Where it falls short The built-in battery life on the 10 oz Ember Mug 2 is limited (around 80 minutes per charge), so if you need several hours of untethered heat while commuting or on long outings, the Travel Mug 2 (14 oz) or non-electrically heated insulated bottles are better choices and cheaper alternatives exist that keep heat passively. If you want exact-temperature sipping at your desk or in an office and can live with a short internal battery or leave the mug on its coaster, buy this; if you need long off-coaster runtime for full-day travel or want a lower-cost thermos that keeps coffee hot without electronics, look elsewhere.

You mostly drink at a desk and want every sip exactly as hot as the first without reheating; the Ember Mug 2 nails precise temperature control and easy app presets.

Skip if

You spend long days away from power or need all-day off-coaster runtime and should choose a travel-sized smart mug with longer battery life or a passive insulated thermos instead.
