## Description

ALWAYS THE PERFECT

Review: Received product. Did not know needed Uk adapter for plug-should be in description. Otherwise would give 5 stars. However mug is fantastic. I set it on ‘hot’- lasts hours with cover on. Love this product.
Review: I purchased a 14oz Nextmug as a gift for my nearly 100-year-old aunt, who absolutely loves very hot coffee. When we ran into some confusion and performance issues with the original mug, I reached out to Nextmug customer service—and I cannot say enough good things about the experience. From the very first response, their team (especially Corey) was kind, patient, knowledgeable, and incredibly thorough. They took the time to understand how the mug was being used, clearly explained how the temperature settings and battery work, and offered practical tips to improve performance. When it became clear that a replacement would be best, they immediately sent a brand-new Slate Blue Nextmug with a new slider lid, along with clear instructions and a prepaid return label for the old one. The replacement mug works beautifully. It keeps the coffee hot just the way my aunt likes it, and she was delighted with the new color. Most importantly, it brought back one of her simple daily pleasures—and at her age, that means everything. It’s rare these days to find a company that combines innovative products with such genuine care, warmth, and fast follow-through. Nextmug didn’t just fix a product issue; they treated us like family. I would absolutely recommend Nextmug, not only for the quality of their mugs, but for the outstanding people standing behind them. —A very grateful customer

## Questions & Answers

**Q: Since the battery cannot be changed out, only charged, how long does the battery last before mug needs to be replaced entirely?**
A: 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?**
A: 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?**
A: 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.**
A: FROM THE SELLER - Thank you for the question.  When using the Spill-Resistant Lid, Nextmug holds 12 fluid ounces.
