真正的'自发热'垫依靠反射宠物自身体温的铝箔/远红外反射层实现，不通电、无发热丝；若产品宣称'自发热'却需插电则为混淆概念，插电款属于电热垫需另评估过热保护

Unverified自发热垫（铝箔反射层反射体温）与插电垫的核心区别：自发热垫无温控上限、绝对安全无漏电风险但只能保温不能主动升温，室温低于5℃时保暖效果有限；插电垫能主动加热但存在漏电/烫伤/耗电风险82% similarUnverified水暖循环式热敷垫（无电流经过垫面）比电阻丝直热式更安全，无电磁场且不会因发热丝折断产生局部过热，适合需长时间使用的重度关节炎宠物，但需定期加水维护79% similarUnverified面料决定保温底子：石墨烯/摇粒绒内胆的电热马甲即使不通电也有基础保暖，续航耗尽后仍能御寒；纯薄涤纶外壳款一旦断电几乎等于没穿，怕充电宝中途没电者应选带蓄热内胆的款式77% similarUnverified该产品主打脉冲加恒温热敷组合，靠电刺激而非机械滚轮或气压揉捏，属于轻量便携佩戴式护颈仪76% similarUnverified插电式加热垫必须选带PTC陶瓷恒温发热材料的产品，其达到设定温度后会自动降低功率，比电阻丝加热更不易局部过热引发烫伤或火灾75% similar
