Before you buy any vape hardware, check for safety marks: CE, RoHS, FCC. These aren't just stickers; they mean the device has been tested for electrical safety, hazardous substances, and electromagnetic interference. Also look for built-in protections: overcharge, over-discharge, short-circuit, and overheat. These keep the battery from becoming a fire hazard.

The WINDBAR SPECTRUM line, for example, includes multiple safety features as standard. It's part of why we stand behind them. But not all cheap devices have this, so read the spec sheet carefully. If a product doesn't list protections, that's a red flag.
