Do hair straighteners need to be charged?

Whether a hair straightener needs to be charged depends on its design type. ‌

Some hair straighteners are designed as wireless charging styles. These hair straighteners are usually equipped with batteries and need to be charged before use. For example, the TYMO 4th generation hair straightener supports wireless use, uses a 65W adapter to charge, supports PD and QC3.0 fast charging protocols, and can be used for 60 minutes after a full charge. In addition, the Dyson hair straightener is also equipped with a four-cell high-energy lithium battery with a battery life of up to 30 minutes, and can switch between wired and wireless modes. ‌
For hair straighteners that need to be plugged in, they usually do not have built-in batteries, so they do not need to be charged. This type of hair straightener needs to be connected to a power source when in use, and is suitable for use at home. For example, the Korean mini hair straightener has a plug-in version and a USB version. The plug-in version is more stable to use, while the USB version requires a dedicated charger. ‌
