Nextmug by NextboomTemperature-Controlled, Self-Heating Coffee Mug (Black - 14 oz.)

Q: Since the battery cannot be changed out, only charged, how long does the battery last before mug needs to be replaced entirely?

FROM THE SELLER: Thank you for your question. The Nextmug battery is rated to be fully charged 1,000 times, after which it maintains 80% effectiveness... meaning it can be charged but may not hold the charge as long as before. You'll be able to enjoy your Nextmug for years to come.

Q: How long does the mug keep your beverage hot when not on the coaster?

FROM THE SELLER - Thank you for the question. Depending on how hot the liquid is when you pour it into the mug, the Nextmug keeps your beverage hot for about 2.5 hours (with the lid on) and about 1.5 hours (lid off) when it's not on the Docking Coaster and set to the "Warm" setting.

Q: What's the inside coating made of? Does it have PFAS/PFOA/BPA?

FROM THE SELLER: Thank you for your question. The Nextmug is made of stainless steel and has a ceramic coating on the outside. The ceramic coating covers the inside of the mug as well as the exterior surface and the handle. The main portion of the mug does not contain plastic. The bottom of the mug (only the portion around the battery) has a plastic exterior. Both the Nextmug and the lids are BPA-free.

Q: How many fluid ounces fit inside the cup with the lid on? I have a competitor's 14 oz mug that holds about 10 oz.

FROM THE SELLER - Thank you for the question. When using the Spill-Resistant Lid, Nextmug holds 12 fluid ounces.
