Chargeur en plastique polycarbonate

I’m glad I received this item and complete. I’m looking forward to keep my coffee warm again my original one stopped working. I will try Monday at work.

We love our Ember mugs and use them daily. But we too have discovered that over time the coaster contact pins will freeze in the recessed position. Upon closer inspection I could see a faint white ring of calcium scale around each pin. I suspect that this may be the problem others are experiencing especially if they have any degree of hard water. But there is an easy solution that will restore those contact pins to their original condition. A small drop of vinegar on each pin will dissolve the calcium. After leaving the vinegar in place for a half hour or more, the pins will usually spring back to life. In some cases, pressing the pins gently with a ballpoint pen while they are soaking will work the vinegar down into the pin holes. After the pins are back in position, dry off the coaster thoroughly, and add a small drop of MTC oil to each pin (a very light weight, non-toxic, culinary oil). This seems to prevent the scale from reattaching to the pins as quickly. We've found that there is no need to replace the coasters, that this procedure works well and consistently restores the contact pins to there original condition.

I have two to cover all my early morning coffees. Considering a third.

Chargers don't hold up. I've had three go bad, and they're stupid expensive. Hopefully my tumbler hasn't gone bad, too - to be determined...

My wife and I both have ember mugs. We have already replaced one charging coaster and now have to replace the second. We have only had the mugs one year.
