Key specs include capacity (700mL to 1.2L for most meals), battery size (10,000-16,000mAh for cordless), max temperature (higher = faster heating and hotter food), and heating time. Cordless vs plug-in affects portability. Consider what's included—insulated bag, utensils, extra containers. Scheduled heating is a premium feature. Container material (stainless vs plastic) affects durability and cleaning. For office use, cordless with 10,000mAh+ battery is ideal. For desk with outlet, plug-in saves money.

Stainless steel heats more evenly, is more durable, and doesn't retain odors. It's easier to clean and doesn't stain. Plastic is lighter and often cheaper but can warp over time and may retain food smells.

Follow manufacturer instructions. Electric lunch boxes are as safe as microwaves when used correctly.
