- Portability and weight: Lightweight, compact units are better for desks, camping, or travel. Consider how easily you’ll move the heater between locations.
- Use case fit: Car use vs. indoor desk use vs. camping require different heat outputs and form factors. Ensure the unit covers the intended area (e.g., up to 10㎡ or more).
- Noise level: Quiet operation preserves comfort in offices or bedrooms. Check decibel ratings if available.
- Maintenance and warranty: Look for straightforward maintenance and a reasonable warranty to protect your investment.
