The problem is specific and real

You make a good coffee, you get pulled into something, you come back to a lukewarm cup and either drink it disappointed or microwave it. The Ember removes that entire pattern — the coffee is the temperature you set, an hour later. If that’s your morning, check the Amazon price.

14 oz vs 10 oz

The 10 oz is an espresso-sized mug; the 14 oz holds a proper filter coffee or a large milk drink and has better battery. For a desk mug, get the 14. People who’ve owned the small one get the 14 oz on Amazon.

Battery, app, care

On the coaster it holds indefinitely; off it, around 80 minutes. Set a preset once and you can ignore the app. Hand-wash only, and don’t scrape it with a metal spoon. Check color options on the Amazon listing.

👍 What executives love

  • Actually keeps coffee at your exact temp
  • Preset mode needs no app
  • 14 oz fits real coffee drinks
  • Charging coaster included
  • Clean, desk-appropriate look

👎 Where it falls short

  • Hand-wash only
  • ~80 min battery off the coaster
  • Premium price for a mug

Who it’s for

Anyone whose coffee routinely goes cold at their desk. If you drink your coffee in ten minutes flat, you don’t need it.

Before you buy — quick answers

10 oz or 14 oz?
14 oz for a desk — it fits filter coffee and milk drinks and has longer battery. The 10 oz is really for straight espresso. Both are on the Amazon page.
How long does it stay hot away from the coaster?
Around 80 minutes on a full charge — enough to carry it into a meeting and back.

A very specific annoyance, completely solved.
