If you’re tired of cold leftovers or waiting in line for the microwave at work, you’re not alone.

HeatsBox is a lifeline for people who are on the move, working long hours, or just want more control over their meals. Whether you’re stuck in a patrol car, juggling after-school pickups, or flying across the country, having a hot, home-cooked meal on your schedule makes a big difference.

Here’s how to get started and make the most of it.

What should you do with your electric lunchbox first? Unbox and Prep
- Take everything out and give it a quick check: the box, stainless steel tray, power cord, and lid.
- Wash the inner tray with soap and water before first use.
- Important: don’t put the base in water. Just wipe it with a damp cloth.
How’s the battery life of HeatsBox GO? Power Up
Here’s everything you need to know related to the battery life and power usage about your HeatsBox GO:
- HeatsBox GO runs on battery. A full charge (about 4 hours) is good for 1–2 heating cycles.
- Aaron, who works 10-hour shifts in law enforcement, charges it in his car during the day.
- Unplug when you are ready to heat it up — GO only heats from the battery.
How much food can your HeatsBox GO hold? All we can say is Load It Up!

Maria, a flight attendant, told us she packs three meals before a 3-day trip. She’s big on homemade food — no fast food if she can help it. She stores her meals using extra Inner Trays and keeps them in a cooler.
HeatsBox trays hold about 31 oz of food. That’s enough for rice and veggies, spaghetti, or even a breakfast spread like eggs, sausages, and toast. Just don’t fill past the MAX line — especially with soups or sauces.
Do you need an App for that? App or No App — You Choose
Tips for Optimal Reheating? We gotcha
- Add 1–2 tablespoons of water to dry food if you want to speed things up.
- Most meals heat in 30–40 minutes. Dense or refrigerated meals may take longer.
- Frozen meals? Yes, but break them into smaller pieces first and expect longer heat time.
You’ll see the light change:
- Red = heating
- Green = ready to eat
Pro Tip: HeatsBox keeps warm for 30 minutes after it’s done.

Kevin sets his HeatsBox on the dashboard while working. “I just hit the app and let it do its thing while I’m writing reports. When it’s ready, I’ve got a hot meal — no gas stations or cold sandwiches.”
What about Clean Up?
Don’t worry, it’s easy.
- The steel tray and lid go in the dishwasher.
- The base? Just wipe it down.
- Don’t forget to clean the silicone ring in the lid — it helps keep things leakproof.
Final Thoughts

People often hesitate because of the price. At around $200, it’s not cheap. But nearly every customer we spoke with called it an investment. Maria said it saved her from buying takeout. Jacky said she eats healthier. Kevin said it’s helped him stick to a new diet.
Yes, it’s more than just a lunch box. It’s freedom from bad food, cold food, or skipped meals.
So if you’re ready to eat better — no matter where you are — HeatsBox might be exactly what you need.
