The daily lunch problem
You shouldn't have to eat cold food
Cold food at work
Lunch made at 7am is stone cold by 1pm.
WarmByte keeps it hot until you're ready to eat — no microwave needed.
Microwave queues
Five minutes waiting behind three coworkers, every single day.
Your food is already hot when you sit down. No queue, no wait.
Soggy reheats
Microwaves turn rice to rubber and curry to a dry mess.
Gentle, even warming holds texture instead of nuking it.
Product in action
Everything built into one lunch box
Even Heating
Heat spreads evenly across the tray, so every bite is warm — not just the bottom layer.
Rechargeable
A 6000mAh built-in battery means no disposable parts and no wall socket required in use.
USB Powered
Charges from any USB-C source — power bank, laptop, or wall adapter.
Timed Heating
Set a countdown from 30 minutes up to 4 hours and let it run on its own.
Temperature Control
Six settings from 30°C to 80°C, so you choose exactly how hot you want your food.
Safe & Reliable
Food-grade stainless steel and a design engineered to heat safely, every day.
