Why BrewKeep Outlasts Every Mug You've Tried Before
Locked-In Warmth from First Sip to Last
BrewKeep holds your drink at 131°F — the sweet spot for flavor, confirmed in independent taste tests. Every last sip hits the same target.
Touch-Free Smart Heating
Set the mug down and heating starts instantly — no app, no Bluetooth. Lift it and power cuts in under a second, every time.
Built Clean, Stays Clean
Food-grade 304 stainless steel means zero chemical leaching and zero rust. Your coffee or tea tastes exactly as brewed — nothing added, nothing lost.
Safe Power, Zero Worry
The 10-hour auto-shutoff cuts power if you forget the mug — no overheating risk. Works with any 5V-2A USB charger you already own.
What our 17,000+ Customers say
Based On Real and Honest Experiences
Every morning I get distracted — emails, rabbit holes, the works. Before BrewKeep, my coffee was already cold by the time I remembered it. Now I come back an hour later and it's still at the perfect temperature.
I read every Ember horror story before buying and almost didn't. Three months in, BrewKeep hasn't missed a beat — no app drama, no broken pins, just perfect coffee all morning. The last sip is as good as the first.
I thought it was overkill. Then I tried BrewKeep — went from forgetting half a mug cold in the sink to finishing every last drop still perfectly warm. Bought a second one for my husband within a week.
Frequently Asked Questions
How long will BrewKeep keep my drink warm?
How long will BrewKeep keep my drink warm?
As long as the mug rests on its powered USB base, BrewKeep holds your drink at 131°F — no battery counting down, no rush to finish. The 10-hour auto-shutoff then cuts power safely, so slow sippers can take their time all morning.
Is it dishwasher safe?
Is it dishwasher safe?
The mug and base are hand-wash only to protect the heating element. In practice it takes under 30 seconds — smooth stainless steel releases residue without soaking. Keep both out of the dishwasher and microwave.
Does it work for tea, hot chocolate, and other drinks or just coffee?
Does it work for tea, hot chocolate, and other drinks or just coffee?
The food-grade stainless steel interior works with tea, hot chocolate, herbal infusions, and any hot drink — zero chemical transfer, zero flavor crossover. BrewKeep holds all of them at a steady 131°F with no interference.
Do I need a phone app or Bluetooth to use it?
Do I need a phone app or Bluetooth to use it?
No app required, ever. BrewKeep heats automatically through the base — no Bluetooth, no firmware updates, no account. Plug in, place the mug, and it holds 131°F. The opposite of the Ember experience.
Can I change the temperature setting?
Can I change the temperature setting?
Fixed at 131°F — the proven sweet spot between scalding (above 150°F) and flat-tasting (below 125°F). Independent taste tests consistently confirm this range delivers the best flavor for coffee, tea, and hot chocolate.
Will it still be hot an hour later if I drink slowly?
Will it still be hot an hour later if I drink slowly?
Yes — that's exactly who BrewKeep is built for. The USB base holds 131°F with no time limit while the mug is on it. Slow sippers who take 60-90 minutes report every sip arriving just as good as the first.
What's the difference between BrewKeep and a regular mug warmer?
What's the difference between BrewKeep and a regular mug warmer?
A mug warmer only heats from the bottom with no precise feedback — the base overheats while the top stays lukewarm. BrewKeep's sensor maintains a consistent 131°F throughout the liquid, adjusting in real time so every sip hits the same target.
Can I put it in the microwave to preheat?
Can I put it in the microwave to preheat?
No — stainless steel and the heating element make BrewKeep incompatible with microwaves. Pour your freshly brewed drink directly into the mug, place it on the base, and it holds 131°F from first sip to last — no microwave trip needed.
