The SmrtMugg GO V3 is a 13.5 oz battery-powered heated mug that keeps coffee or tea at the temperature you like. Pick one of four settings (122°F, 131°F, 135°F or 140°F). The GO lets a too-hot drink cool to your setting, then holds it there, so every sip tastes the way it should. From a full charge, the battery holds 135°F for about 90 minutes; runtime is shorter at higher settings or with a cooler starting drink. At your desk, leave the magnetic charging cord attached to keep your drink warm all day. Operation is simple: hold the single button to turn the heat on or off, tap once to see the current drink temperature, and tap again to check remaining battery. To clean, remove the lid and hand wash (not dishwasher safe). The lid is not leak-proof, so keep the mug upright when you travel. A simple, affordable gift for the coffee or tea lover in your life.
4 ADJUSTABLE TEMPERATURES: Choose 122°F, 131°F, 135°F or 140°F. The GO lets hot coffee cool to your setting, then holds it there so the last sip tastes as good as the first.
ABOUT 90 MINUTES PER CHARGE: From a full charge the GO holds 135°F for about 90 minutes. Runtime is shorter at 140°F or when you start with a cooler drink. For all-day warmth at your desk, leave the magnetic cord attached.
ONE-BUTTON SIMPLE: Hold the button to turn the heat on or off. Tap once to see your drink’s current temperature, tap again to see how much battery is left.
SNAP-ON MAGNETIC CHARGING: The included 40-inch magnetic cord snaps right on. Fully charge the mug before first use.
CARE AND LID: Hand wash only, not dishwasher safe. The lid is removable for cleaning but is not leak-proof, so keep the mug upright in bags and cup holders.
Customers report significant reliability issues with the coffee mug, noting that it doesn’t work after a week of use and fails to heat up at all. The battery life is also problematic, with customers mentioning that it may not last all day.
