12V Travel Heated Mug - Black

16 oz. is the perfect size for my needed car mug. It heats to about 150℉ and maintains that temperature as long as it's plugged in. The temp will slowly drop when unplugged but remains drinkable for about 30 minutes if you keep the lid closed. The lid slider is a little stiff to move because it has a rubber insert to make a good seal when closed. The slider easily snaps out of the lid for cleaning, but stays in place during use. The mug is easy to hold, but my 74 year old hands needed a handle. So the one in the attached photos I found on Amazon fits it perfectly. ( ASIN B01I90QJZM ) The mug and handle fit the cup holder in my 2014 base model 5-speed Tacoma very well. The included 12v power cord is long enough to use in my truck.I also use a 12v 48w power adapter in the house that has a USB-C attachment. Plenty of capacity to keep the coffee in this 12volt 21watt rated mug at 150℉.Since this mug does not have auto shutoff, be sure to unplug it when nearly empty so the heating element doesn't burn out.The rubber seal covering the USB-C power port when not in use will help keep water out when cleaning as long as you don't submerge the mug. I think it is a good value and so far I am satisfied with this mug and hope it gives me a few years of service.

I was incredibly excited to get this Wagan travel mug. Between my regular cross-border commutes down to Redmond and long hours on the road, having a reliable heated mug that could keep my coffee hot via USB-C or a 12V car socket sounded like the perfect solution. Unfortunately, this product turned out to be a complete dud right out of the box.Dead on ArrivalThe moment I unboxed it, I filled it up and plugged it into a standard USB port at my desk. Nothing happened. The red indicator light that is supposed to show it's actively heating never turned on, and the mug stayed completely cold.Extensive TroubleshootingI figured maybe it just needed a more robust power delivery source, so I swapped it over to a high-output 65W charger. Still nothing—completely unresponsive. Thinking maybe the USB-C function was just faulty, I took it out to the car to test it there. I plugged it in, turned the engine on, and again, absolutely zero power, zero heat, and zero indicator lights.Final VerdictIt doesn't matter how nice the stainless steel looks or how well it fits in a cup holder if the core heating mechanism doesn't work. It seems like I received a completely defective unit, and looking at some of the other reviews, it looks like I’m not the only one dealing with serious heating and reliability issues.Save your money and look for a brand with better quality control. This one was essentially a completely useless brick from the second I opened the package. Will be returning immediately.

I drive a route, so I stay close to my truck and keep this plugged in most of the time. I love it. When it’s unplugged, it doesn’t hold heat as long as an insulated mug, but that’s not an issue for me. Most of my night is spent driving. When I step away, it’s usually for about an hour. It still stays hot enough, and once I’m back in the truck, it heats right back up to piping hot. If the cup gets low, I just add more and it heats that up too. Works great for how I use it.

This handly little item is great for people who like to space out drinking their hot beverages instead of trying to drink them in a short period of time. It can be used at home and on the go though it will cost more to use it at home.The item uses a cigarette-lighter, male plug to channel power, from an auto cigarette lighter, to the mug. It requires at least 90W of DC power (not the 20W stated in the ad) which most USB systems can't provide plus a cable that can handle 90W. I tried a number of USB hubs and cables before giving up and buying a 180W AC to DC Converter with the required, female cigarette-lighter port. If you buy a converter, it needs to be at least 90W. The coverter cost almost as much as the mug but it is still only half the price of other, quality beverage warmers for the home. While cheap ones are available, I haven't found any satisfactory.The problem with most mug warmers is the beverage, such as coffee or tea, oxidizes from exposure to the air in an open mug. The benefits, of the drink, fade fairly quickly when expose to air.This mug can be closed, when not being used, so that the drink doesn't oxidize as quickly. It also keeps the drink uniformly hot. I have a pretty sensitive mouth, but I find I can comfortably drink the contents until they are gone. That might not be the case if the preheated beverage is hotter than usual so be careful not to add anything that would burn the mouth.I have only one gripe, about the mug, and that is the size of the lip hole. It appears to be designed for a fairly large mouth so anyone, with a small mouth, will have to be careful when drinking or hot liquid might run out from the sides of the hole. I had this happen several times. I'm going to see if I can't find a way to reduce the size of the hole for my small mouth.Other than that, it is a very useful mug, with a quality build, and it holds 16oz of liquid which I find lasts me about 4 hours before needing to be refilled. With care, it should last a long time. Just be sure to read the requirements for care before washing it.

Let me just say I am extremely Happy!!!!😄 I had the ember mug and it was ok for the price I paid to keep having malfunctions and constant disconnection problems. It's junk now what a waste of money!!. And it doesn't heat up to 150° like this travel mug!!. It's not too hot but still hot enough. Perfect for winter time at a fraction cost better than those expensive ones. Let's hope it'll last long enough. 🤞
