Smart USB Coffee Cup Warmer with Pressure-Induced Auto On/Off, Coffee Accessories for Home Office Desk

Works great. Nothing to switch on or off. Just put the cup on it. When you lift the cup off, it turns off. I have another cup warmer that’s more complicated to use. I really enjoy this one! And it heats at about 130 degrees F. Just perfect!!

Keeps coffee warm. Charges my phone. Doesn’t look or feel cheap. Good product overall. Would by again

Excellent product.

I was spoiled from using an Ember cup for the last 3 years, so when it died I couldn’t go back to the quick cooldown of my old ceramic mugs. But I didn’t want to spend 100 bucks for a new Ember mug so I compromised and bought one of these hot plates instead. It works fine, except for one thing, the spring loaded switch that turns it on and off gets stuck in the on position sometimes so I need to pay close attention to the power light and make sure it’s off when I’m done using it. Not sure if other people have this problem as well but it’s not something I’m overly concerned with so I’ll keep it, but it’s the reason I give it 4 stars instead of five.

This works great for keeping my coffee hot all the time, and I like the on switch on the bottom of the unit so it goes off when I take the cup off it.

This is a great cup warmer, but beware of letting a book rest on it. The warmer comes on and my wife scorched her Bible. Not the products fault, but a concern to beware of. Keep away from children obviously, would be my advice. The cup turns on the warmer and when the cup is removed it goes off. And there are USB plugs for your phone, etc. I bought it for my wife and will now buy one for me.

I had bought two for my wife.. one for the office and one for the family room... the office one quit after the first couple of days. The family room one was doing it's job at keeping coffee warm, however today it almost caused a fire. When it heats up, (by the way it does have a microswitch to turn it on and off when the weight of a cup is pushes down on its surface), its keeps on going and as you are not able to control the temp of the surface, there is no way to turn it off if the microswitch fails. It gets so hot that it will melt objects, burn paper and fuse plastic to it's surface. Fortunately the smell of burning gave it away and I was able to unplug it. I can't imagine what might have happened if we had gone out for the day. This also can seriously burn you.I would not recommend this product to anyone. I have attached photos of a book that was burned and plastic that melted onto the surface.Paper burns at around 451f. Amazon should not be selling this product. It's a safety and fire hazard.

This is the second cup warmer and I’m happy. This one turns automatically on when I put a filled cup on it and keeps it hot as long it’s on. Just remember that not all cups or mugs are flat on the bottom, that makes a big difference. A regular cup usually has a rim, which doesn’t keep as much heat.The cheaper versions need to be put on a heat proof surface, but not this one …it doesn’t get hot underneath.I love it!
