Electric Lunch Box Review — Best 100W Heated Food Warmer for Work?
A 1.5 litre stainless steel electric lunch box with a 100 W element and three leads for mains, car and truck. The 304 stainless inner is the reason to choose it over plastic-lined rivals, and it washes properly. It reheats rather than cooks, takes twenty to thirty minutes and has no timer.
TRAVELISIMO 1.5L 100W Heated Food Warmer Review (2026) — Is an Electric Lunch Box Better Than a Microwave Queue?
The problem an electric lunch box solves is not cooking. It is the eleven-minute queue for the one microwave on your floor, or the fact that a van, a cab or a site office does not have a microwave at all. Cold food from a plastic box is the default because reheating is inconvenient, not because anyone prefers it.
This is a 1.5 litre stainless steel container with a 100 W heating element and three power leads: mains, 12 V for a car and 24 V for a truck. The strength is that it turns any journey or any parked half-hour into reheating time. The compromise is that it is a warmer, not an oven, and it takes twenty to thirty minutes rather than ninety seconds.
In short: the electric lunch box earns 8.3/10 from the Blue Rays Technologies team. The rest of this electric lunch box review sets out exactly how that score was reached.

How Long an Electric Lunch Box Really Takes
The manufacturer quotes twenty to thirty minutes at 100 W, and that is accurate for a full 1.5 litre container taken straight from a fridge. A half-full box of something wet, such as a stew or a curry, is closer to twenty. A dense, dry portion like rice with a chicken breast on top is closer to thirty-five and benefits from a stir halfway.
That timing is the whole design brief. You plug it in when you park up or when you sit down, you do something else, and the food is ready when you are. It is not a device you use when you are already hungry and standing next to it.
The 12 V lead is slower in practice than the mains lead, because a car socket is fused well below what the element would happily draw. Plugging in at the start of a commute rather than at the end of one is the fix.
Stainless Steel Is the Reason to Choose This One
Most cheap heated boxes use a plastic inner tray. Plastic stains, holds the smell of last week’s chilli, and warps slightly at the seal after a few dozen heat cycles, which is the usual route to a leaking bag.
The 304 stainless inner here washes properly, goes in the dishwasher and does not retain odours. It also conducts heat far better, which is part of why the reheat time is competitive despite a modest 100 W element.
The trade-off is weight and a slightly higher price than the plastic-lined competition. For something you carry every working day in a rucksack, the extra few hundred grams is real, and it is the one honest argument for the cheaper alternatives.
Food Safety Is the Part Most Buyers Get Wrong
A heated container is a reheating device, not a refrigerator. Food that has sat in a warm van since seven in the morning has been in the danger zone for hours before it is ever plugged in, and warming it up does not undo that.
The correct routine is to keep the box cold until you heat it — an insulated bag with an ice pack, or a fridge if the site has one — and then heat it thoroughly in one go. US guidance is to reheat leftovers to 165 °F (74 °C) throughout, and this unit will get there in a full cycle but not in a rushed ten minutes.
It is also worth saying plainly that this is not a slow cooker. Leaving raw ingredients in it for the morning and expecting a cooked meal is the failure mode that produces the small number of one-star reviews.
Limitations and Compromises
No product is without compromise, and the electric lunch box has a clear set of them.
It reheats, it does not cook. Anything that needs to reach temperature from raw is out of scope, and buyers who expected a portable slow cooker are the largest single source of disappointment in the review history.
There is no timer and no thermostat display. You plug it in, a light tells you it is working, and you judge the time yourself. That is fine once you know your own portions, and mildly annoying for the first week.
The 1.5 litre capacity sounds generous and is genuinely a large single portion, but it is one compartment. There is no separate section to keep a salad cold or a sauce apart, so anything you do not want heated has to travel in something else.
Cleaning, Sealing and Cable Care
Wash the stainless inner after every use rather than at the end of the week. It is dishwasher safe, and the outer shell and lid seal should be wiped by hand and dried before the lid goes back on, or the seal develops a smell of its own.
Never submerge the outer housing. The element and the wiring live in the base, and water in there is the failure that ends the product rather than a fault you can dry out.
Coil the leads loosely rather than wrapping them tightly around the box. The 12 V lead in particular fails at the plug end first, and a tight wrap concentrates every bend at exactly that point.
Who Should Buy It?
The electric lunch box suits some households far better than others.
- You drive for a living, or work somewhere with no microwave
- You are tired of queueing for the office microwave at half past twelve
- You want a stainless inner rather than a plastic tray you cannot get clean
- You want one box that works on mains, in a car and in a truck
- You bring leftovers to work most days and want them hot
- You want a container that survives the dishwasher rather than one you hand-wash forever
Look elsewhere if any of the following describes you.
- You want to cook raw ingredients rather than reheat cooked food
- You need food ready in under five minutes
- You want separate compartments for hot and cold items
- You carry your lunch a long way on foot and want the lightest possible box
- You already have a microwave you can reach without queueing
The Verdict
As a way of getting a proper hot meal in a van, a cab or an office with one overworked microwave, this does exactly the job. The stainless inner is the deciding feature against the plastic-lined competition, the three voltages cover every realistic situation, and 4.5 across nearly twenty-five thousand ratings is an unusually large evidence base for this category.
It lands at 8.3 rather than higher because of what it leaves out: no timer, no temperature readout, one undivided compartment, and a reheat time that is only convenient if you plan around it. Buy it as a reheating box for a routine you already have and it is very good. Buy it hoping to cook in it and it will not.
Review score for the electric lunch box: 8.3/10. Strong on build quality, three-voltage flexibility, cleaning and evidence base; the compromises are a twenty to thirty minute reheat, no timer, a single compartment and no cooking capability.

Frequently Asked Questions
The questions buyers ask most often about the electric lunch box, answered plainly.
How long does the electric lunch box take to heat food?
Twenty to thirty minutes from refrigerated for a full 1.5 litre portion. Wet food such as curry or stew is at the faster end; dense dry portions like rice take longer and benefit from a stir halfway.
Can you cook raw food in it?
No. It is a reheating device rated at 100 W, not a slow cooker. Raw ingredients will not reach a safe temperature reliably, which is the single most common cause of a disappointed buyer.
Does it work in a car?
Yes. It ships with a 12 V car lead and a 24 V truck lead as well as the mains lead. The vehicle leads are slower than mains, so plug in at the start of a journey rather than the end.
Is it dishwasher safe?
The 304 stainless inner container is dishwasher safe. The outer housing contains the element and wiring and must only be wiped, never submerged.
