A powerful 7,200 mAh battery heats your food anywhere — the office, a train, a job site. Enjoy warm, home-cooked meals on the go, with no outlet in sight.
Water-free heating
Modern direct-heat technology warms food evenly from below — no steam, no water tray. Taste and texture stay intact; nothing turns soggy.
Adjustable temperature
Multiple heat settings let you pick the ideal temperature for every dish. Soup, rice, or vegetables — your meal, exactly the way you want it.
Removable stainless-steel container
The food-grade 304 stainless-steel inner container lifts right out and is dishwasher safe. Hygienic, easy to clean, and your food never touches plastic.

REVIEWS
Rated 4.8 by 312 verified buyers
"Ate a hot curry on a construction site with no power in sight. Food tastes like it just came off the stove — nothing soggy."
"I've stopped queuing for the office microwave. Set it at 11:30, hot lunch at noon. The steel container cleans up in seconds."
"Battery easily lasts two heat cycles. Wish it came in more colours, but the build quality is genuinely premium."
"Bought it for long train commutes. 900 ml fits a proper full meal — I'm saving about £50 a week on takeout."
"The adjustable temperature is the killer feature. Soup on high, leftovers on medium — everything comes out right."
"Swapped from a cheaper one that needed water and made everything mushy. This heats dry, evenly, and quietly. Worth every penny."
FAQ
Questions, answered
How long does it take to heat a meal?+
Typically 20–30 minutes to serving temperature, depending on the dish and heat setting. Start it before your break and lunch is ready when you are.
How many meals per battery charge?+
The 7,200 mAh battery covers 1–2 full heating cycles per charge. It recharges over USB-C in about 3 hours — or use it plugged in.
Is it safe to wash?+
The removable 304 stainless-steel container is dishwasher safe. The outer shell houses the electronics — wipe it with a damp cloth, never submerge it.
Does it need water to heat food?+
No. ThermalBox uses direct dry heating, so food warms evenly without steam — no soggy rice, no watered-down flavour, no water tray to refill.
What's in the box?+
Every order includes the ThermalBox itself plus a USB-C charging cable — normally £14.99, and yours free.
When will my order arrive?+
Orders are dispatched within 1–2 business days with tracked delivery, arriving in 3–5 business days across the UK. Free shipping on all orders.
