Ember smart mugs are a neat piece of technology that can maintain your beverage at a constant temperature, but the spring pin contacts used in their chargers are prone to wearing out over time. if this happens, your charger won’t make firm contact with your Ember mug’s charging port and the mug won’t recharge properly.
Fortunately, you can easily replace these contacts yourself with only basic household soldering tools and a bit of know-how. YouTube has several videos detailing how to make this repair, which can get your expensive smart mug back up and running in short order. While I have not completed the repair myself, many videos online have shown the repair using Harwin’s spring contact. 952-3127-1-ND.
Here is one video that shows how to get to your contacts to see if that is the issue.
