Electric lunch boxes solve a specific office problem: a slow or nonexistent microwave queue. This comparison uses manufacturer specifications and aggregated verified-buyer feedback for a well-known stainless lunch crock and two multi-function electric lunch box models from the same brand at two power tiers. BuyingBench did not purchase or physically test any of these three products; see the evidence and review record below for what this article is based on.
| Spec | Crock-Pot Lunch Crock (20 oz) | TRAVELISIMO 60W 3-in-1 | TRAVELISIMO 80W Stainless |
|---|---|---|---|
| Capacity | 20 oz | Roughly 1.5L, manufacturer-stated | Roughly 1.5L, manufacturer-stated |
| Power source | Wall outlet | Wall outlet, car, and USB-C power bank (3-in-1) | Wall outlet with step-up wattage for faster heating |
| Container material | Stainless steel insert | Stainless steel insert | Stainless steel insert |
| Brand track record | Well-known slow-cooker brand’s dedicated lunch line | Newer brand focused specifically on electric lunch boxes | Same brand as the 60W model, higher-wattage variant |
BuyingBench Research Score — these reflect our comparative analysis of manufacturer specifications and aggregated verified-buyer feedback, not a hands-on lab test.
Our overall pick is the Crock-Pot Lunch Crock Food Warmer: it comes from a long-established slow-cooker brand, its 20 oz stainless insert is sized for a real single-portion meal, and buyer feedback is both extensive and strongly positive. The TRAVELISIMO 60W 3-in-1 is the most flexible on power source, running from a wall outlet, a car, or a USB-C power bank, useful if lunch sometimes happens away from a desk. The TRAVELISIMO 80W Stainless steps up the wattage for faster heating, but we have the least independent verification on this specific variant, so we’re keeping that recommendation modest.
The Crock-Pot Lunch Crock comes from an established brand with extensive, consistently positive buyer feedback.
The TRAVELISIMO 60W’s three power options (outlet, car, power bank) add real flexibility for lunches away from a desk.
All three use a stainless steel insert rather than a plastic liner.
None of these units reheat as quickly as a microwave — plan for roughly 25 to 40 minutes depending on the model.
The TRAVELISIMO 80W variant has less independent verification in our research pass than the other two.

For most office lunches, the Crock-Pot Lunch Crock is the safest starting point on brand track record and feedback volume. If you sometimes eat lunch away from an outlet, the TRAVELISIMO 60W’s car and power-bank compatibility is a genuine advantage. The 80W step-up model is worth considering if faster heating matters more than the extra verification the other two have.
