This USB-C accessory gave my iPhone and Android an unexpectedly useful superpower

A ZDNET review assesses the Heat It smartphone-powered insect bite healer—a USB-C/Lightning dongle controlled via iOS/Android that heats to 124°F/51°C to reduce itch and swelling—highlighting adult/child modes, sensitive skin options, and short/medium/long treatments. The reviewer reports strong relief across various bites with mild heat sensation, modest phone battery use (~0.1% per application), and recommends the device despite its $40 list price ($30 on sale) due to effectiveness and compact, keychain-friendly design.
