谢谢大家我看上honeywell的，写信去问，人家说不能220v，也不鼓励你用变压器。 Unfortunately, we cannot recommend that any of our products be used in foreign circuits and outlets, even if used with a converter. Our products were not manufactured to be able to handle a power-source change, and using them in an unfamiliar outlet will almost definitely cause a product malfunction. Due to these recommendations, using any unit in this manner will void the Limited Warranty. We sincerely apologize for any inconvenience.
