Most listings specify ABS plastic (Acrylonitrile Butadiene Styrene), other plastics, or combinations of metal and plastic. Common constructions are ABS or mixed metal/plastic housings.

Listings include both USB-powered (plug-in) models and USB-rechargeable models with built-in batteries. Some specify USB-A or USB-C charging ports, while others are designed to run directly from a USB power source.

Reported full charge times range from about 1 to 3 hours. Runtimes vary widely: on low or lowest settings listings report roughly 10–80 hours, while on high/maximum settings runtimes can be much shorter (examples note values as low as about 5 hours).

Reported runtimes span a wide range: about 1.5 hours at the shortest end up to about 80 hours at the longest. Many listings show typical runtimes around 10–25 hours, depending on brightness setting and battery type.
