Buyers must prioritize wattage and heating efficiency, typically ranging from 1200W to 2400W for consumer models. For industrial use, look for all-steam or boiler-integrated systems. Ensure the soleplate material aligns with quality standards; ceramic and titanium coatings are preferred for non-stick properties and even heat distribution, while stainless steel offers high durability. Additionally, verify voltage compatibility (110V for North America vs. 220V-240V for Europe/Asia) to avoid electrical failure.
