VOBAGA Auto Shut Off
If you often have a tendency to forget your stuff (and even forget to shut off your used devices at times), then this VOBAGA Auto Shut Off warmer is optimal. As the name suggests, this coffee warmer has an automatic shut-off after four hours. Once the warmer is turned off, a blue light will flash to alert consumers that the warming plate still feels hot. After each usage, the warmer should be cleaned.
Also, this VOBAGA Auto Shut Off warmer has 3 temperature settings: 104°F, 131°F, and 149°F. In addition, the waterproof nature of the 20-watt gadget helps safeguard it from accidental spills. The heating plate is 3.5 inches in diameter, which should fit most cup dimensions, and the cable is 60 inches in length (which is on the extended side).
The one drawback noted by some reviewers is that the concave surface, which aids in accommodating the form of the mug, makes your cleaning process somewhat more difficult than a flat-top surface.
