Ember Charging Coaster 2 Rose Gold

As everyone else is saying, the pins fail and you’re just out of luck.

on my 3rd charger as pin sticks - this is a FLAWED DESIGN FOR SURE !!!!

The second coaster has broken. I love the mug, but the repeated coaster failures make it hard to recommend this product. After barely a year of use, the pin failed to bounce back for charging. I use this mug five days a week for work, but the coaster isn’t waterproof or durable. This is my second failed coaster, and now I have to buy another one just to keep using my mug.

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...

I got the mug from my son on Christmas Day as gift however the charging coaster in not doing it’s job due to the contact pin on the coaster does not spring up for recharging

I received my mug for a Christmas present and love it. I bought the sliding lid and an extra charging coaster. I wish there was a charger that I could plug into a USB outlet rather than electrical outlets. I have tons of USB options at work. Also, I would love it if the temperature maximum was 150 degrees. I understand if the maximum was determined for safety reasons. However, I like my beverages at 150-155 degrees.

I have had to purchase two replacement charging coasters for my Ember Mug. I love it, but the pins on the charging base always fail over time. Ember needs to offer an annual subscription for new Charging Coasters, because you'll need a new one each year, from my experience.

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

Had two. They both broke. The little pop-up contact stops popping up.

This is my 3rd or 4th charging coaster. The prongs break easily.

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.

In April of this year, I purchased 2 14oz Ember Mug 2, and a travel mug. The Ember Mug 2 bases have a pin recessed so it will not charge the mug anymore. It didn’t even last 1 year, holy smokes. I cannot in good faith recommend this product.

They don’t last more than a year or two.. Replacement is a pain

I was given the Ember cup as a gift . I was excited to get as is a coffee drinker and moves around with my coffee cup. It worked perfectly well for about a month and never heated neither has the light connected . I tried getting it returned for a working one but was never successful. I still have it like a souvenir as it doesn’t work.

They need to fix the springs under the electric leads. When they break the charger becomes inoperable.

Like everyone else…the pins are flawed. I loved my ember mug but what’s the point if you can’t charge it?

Enjoy the mug but one of the pins stopped working, so it doesn’t charge anymore.

I use the mug twice a day. Have used Ember for years. No charger has ever lasted more than a year.

Run!! Do not purchase unless you’re in the habit of throwing away money. For a company to continue to put out this product without recognizing its flaws is mind boggling. The theory of the mug is genius, the long term execution is where reality sets in. The mug will stop working because of the defective pin design. It’s just a matter of when. 3 months? 5 months which was my experience, or the day after the warranty runs out. I’m on my second coaster and the same thing just happened. I received my coaster in March of this year. Buyer, you’ve been warned..

I have used and bought ember cup and charger for over 5 years now and while I really like the setup and the software but here is the problem 1. The cup itself is overall great until after 9 months give or take based on how often you clean it the ceramic coating wears of, I use soft brush too, I still use it but don't like heated metal directly on my coffee 2. The coaster is really the worse part of the system. I've complained several times but nothing ever comes of it. The problem with this charging coaster is the spring pins they use. These pins wear out if you use the coaster all the time, they have a use fail point. I've bought 2 sets and 7 coasters in 5 years. They need to be bigger and stronger pins. All my coasters have failed but the last one using now. There are repair kits but its not clean when you take it apart and you need soldering iron and know what you are doing. I could make a better one, I'm a mechanical Eng. Better yet they should also just provide a USB-C or Micro-USB connector on the cup itself, would never fail
