Description

The BigFun! High-Lighter is a 510-thread cartridge battery built to look like an ordinary highlighter pen – 4.8 inches long, 0.6 inches wide, and unremarkable sitting on a desk or clipped in a bag. Underneath the disguise it is a proper variable-voltage battery: 650mAh, five voltage settings, a pre-heat mode and USB-C charging.

Why it stands out

• Highlighter-pen form factor – discreet by design rather than by accident
• Variable voltage from 1.8V to 3.8V, changed with a single button click; the LED colour tells you the setting
• Pre-heat function via a two-click press for thicker oils in cold weather
• 650mAh cell with USB-C charging, so it takes the same cable as most modern devices
• Both auto-draw and five-click on/off activation

Compatibility

Fits most standard 510-thread cartridges. Very wide-base or oversized cartridges may sit proud of the housing and break the highlighter silhouette.

Care

Charge with a standard USB-C cable and avoid leaving it on the charger overnight. Wipe the 510 connector with a dry cotton swab if a cartridge leaks.

Good to know

This is a cartridge battery, not a vaporizer with its own chamber – cartridges are sold separately. Start at the lowest voltage with a new cartridge and step up only if the draw feels thin.
