Repair, Service, and Parts

Ember repair, service, and parts

Acme Revival is an independent repair network that operates separately from the manufacturers whose devices we service. Our independence enables a repair model that exists beyond manufacturer-controlled strategies, while preserving the ability to work with manufacturers where appropriate.

Temperature-Control Drinkware
End Use Segment

Ember Technologies, Inc. is a U.S.-based consumer technology company specializing in electronically temperature-controlled drinkware. It is best known for the Ember Mug and Ember Travel Mug/Tumbler families, which integrate heating elements, rechargeable batteries, temperature sensors, embedded electronics, and app-connected controls to maintain beverages at a user-selected temperature. Ember describes its products as self-heating drinkware rather than conventional external mug warmers, with the heating system built directly into the vessel. The company has developed a substantial patent portfolio around actively heated and cooled drinkware and has expanded its technology into additional temperature-control applications. Ember states that more than 4 million of its products have been sold.

2 Most Seen Failures:

Charging Coaster Contact Pin Failure

The spring-loaded gold pins in the charging coaster can stick, collapse, or lose spring tension, preventing reliable electrical contact with the mug. This commonly causes intermittent charging, charging only in certain positions, or complete failure to charge.

Battery Capacity Degradation

The internal lithium-ion battery can deteriorate until runtime becomes very short or the mug works only while sitting on the charging coaster. Severely degraded batteries may also prevent normal power-up, resetting, or firmware operations.

Charging Contact Corrosion

Moisture on the mug base can corrode or discolor the gold charging rings and coaster pins, increasing contact resistance and causing intermittent or failed charging. Ember specifically warns that placing a wet mug on the coaster can produce this failure.

Interior Coating Peeling or Flaking

The interior coating on Ember Mug and Cup models can scratch, bubble, wear through, or peel away over time. Reports occur even with careful hand washing, although Ember warns that metal utensils and abrasive cleaning can accelerate coating damage.

Bluetooth Connection Failure

The mug can repeatedly disconnect, refuse to reconnect, or fail to enter a stable pairing state with the Ember app. Factory resets and Bluetooth re-pairing are frequently required when stored connection data or the mug's communication state becomes corrupted.

Mug Will Not Power On

Some units become completely unresponsive even after being placed on a known-good charging coaster. Causes reported in aging units commonly include a deeply discharged or failed battery, poor charging contact, or an internal electronics fault.

Battery Will Not Reach Full Charge

Some mugs remain stuck at a low or intermediate battery percentage despite spending hours on the charger. The symptom can result from degraded battery cells, intermittent coaster contact, or charging-control problems inside the mug.

Liquid Detection or Temperature Sensing Failure

The mug may incorrectly report EMPTY or COLD despite containing liquid, preventing the heater from operating normally. This points to abnormal temperature-sensor readings or failure of the liquid-detection logic based on temperature change.

Travel Mug Display or Touch-Control Failure

Travel Mug and Travel Mug² models can develop unresponsive or abnormal hidden display and touch-control behavior, making onboard temperature adjustment or status viewing unreliable. Resetting may recover the unit temporarily, but persistent cases indicate a display, touch-sensing, or internal control fault.

  1. 1 Repairs are performed on a best-effort basis. Acme Revival utilizes a network of sophisticated technicians and engineers with diverse service offerings; despite this, factors that influence the repair outcome may ultimately prove unsuccessful. Acme Revival makes no claim that it can, guarantee a repair before your device is sent in for diagnostic evaluation; even then, repair and diagnostic work are not mutually exclusive. Despite well-intentioned quoting, repairs may still prove unsuccessful.
