HeatsBox Go Review: Worth It Only If You Really Need Cordless Lunch

By Editorial Team Editorial | April 2026

Microwave queues are a waste of time, and cold leftovers are worse. The HeatsBox Go is the rare lunch box that actually fixes both, with proper cordless reheating and timed app control that makes it useful for office days, site work, and travel.

Based on hands-on research, expert review consensus (RTings, Wirecutter, relevant subreddits), and current pricing.

Best overall: HeatsBox Go

HeatsBox Go — £129.99

This is the pick if you need hot food on your schedule, not the building’s. The 100W bottom heating, 15–25 minute heat time, and 85°C max temperature are enough to reheat a proper meal instead of just taking the edge off.

Why we picked it:

• The integrated rechargeable battery is the headline feature: you can heat lunch away from a plug, which is the whole point here.
• The 925 ml stainless steel insert is leakproof and removable, so it’s easier to clean and better for meal prep than cheap all-in-one plastic boxes.
• App control plus manual start gives you timing flexibility, so you can kick off heating before your break instead of babysitting it.

The trade-off: Battery life is the weak spot, and user reviews on Trustpilot call out poor performance and long charging times. If you only eat near a microwave or desk socket, this is expensive overkill.

If you want the cordless route, buy the HeatsBox Go and stop wrestling with lukewarm leftovers.

Best upgrade: HeatsBox Style

HeatsBox Style — £129.99

The upgrade only makes sense if you like the HeatsBox heating approach but don’t need battery power. The plug-in design gives you the same brand idea without the cordless compromises, which is the cleaner choice for a desk, office kitchen, or home base.

Worth it if: you always have access to mains power and want to skip the battery anxiety entirely.

Best budget pick: Crock-Pot 28-Ounce Mini Electric Heated Lunch Box

Crock-Pot 28-Ounce Mini Electric Heated Lunch Box — £29.99

This is the smarter buy if you just want to warm leftovers at work without spending serious money. It’s compact, spill-resistant, and easy to live with, but it needs a plug and its smaller capacity is a real limit if you pack bigger meals.

Worth it if: you want a simple office lunch warmer and do not care about cordless use or app scheduling.

How we chose

We looked for three things: real reheating performance, portability that actually helps in daily use, and the least annoying ownership trade-offs. We also checked current pricing and user complaints, especially around battery life and charging, because that is where lunch boxes like this usually disappoint.

Frequently asked questions

Does the HeatsBox Go actually heat food properly?
Yes. With 100W heating, a 15–25 minute cycle, and an 85°C top temperature, it reheats food properly rather than just keeping it warm.

Is it worth £129.99?
Only if cordless heating matters to your routine. If you can use a microwave or a plug-in warmer every day, the price is hard to justify.

How long does the battery last?
Not long enough for everyone, and that is the main weakness buyers should expect.
