Ember Mug 3’s unreliable app and short battery life weaken its appeal
The Ember Mug 3 is a well-made, self-heating mug that keeps drinks at a chosen temperature for hours, which could appeal to people who sip slowly. However, the reviewer finds it difficult to recommend at $150 because unreliable app controls and limitations with charging undermine the convenience it promises.
The 14-ounce mug feels sturdy and is top-rack dishwasher safe, and its lid helps retain heat for longer. In testing, the battery ran out within two hours when the mug started at 30 per cent charge and was set to 145°F; performance was better with a full battery. The Android app sometimes failed to apply settings or connect over Bluetooth, while on-mug controls are limited to a few presets accessed by a button on the base.
- The mug keeps drinks warm, but costs $150.
- Battery life and charging can be frustrating.
- The Android app was unreliable in testing.
