Big fun high-lighter

Big Fun High-Lighter makes one item available here: a 510-thread battery shaped like a standard highlighter marker, built for discretion as much as function. Behind the familiar silhouette sits a 650mAh cell with five voltage settings spanning 1.8V to 3.8V, auto-draw activation, and Type-C charging, offered in Yellow, Blue, or Pink. Anyone shopping batteries by feature rather than looks should note the variable voltage range — a meaningful step up from single-setting pens.
