BIGFUN! High-Lighter Cartridge Battery

The BIGFUN! High-Lighter 510 Concealer Cartridge Battery is the discreet 510 thread battery you never knew you needed — cleverly disguised as a classic highlighter marker so it blends seamlessly into any bag, desk, or pocket. Whether you're at home, at work, or on the go, this novelty-style concealer battery keeps your sessions low-key without sacrificing a single ounce of performance.

Under that playful highlighter exterior lives a capable 650mAh battery paired with variable voltage ranging from 1.8V all the way up to 3.8V, adjustable with a single button click. Whether you prefer a smooth, flavor-forward low-voltage draw or a warmer, more robust hit at higher voltage, the BIGFUN! High-Lighter gives you full control over your 510 cartridge experience.

Auto-draw activation means there's no button to hold — just inhale and go. For thicker oils and concentrates that need a little coaxing, a two-button-click pre-heat function gently warms your cartridge before your session, helping you get the most out of every last drop. The five-button-click ON/OFF safety lock keeps the battery from firing accidentally when it's stashed away.

Compatibility is never a concern with the universal 510 thread connection, making the BIGFUN! High-Lighter one of the most versatile discreet vape batteries on the market. It works with the vast majority of standard 510 cartridges, giving you the freedom to pair it with your favorite oil, concentrate, or CBD cart without limitations.

Recharging is fast and convenient thanks to the modern Type-C USB charging port, the current standard for reliable, reversible, everyday charging. At 4.8" x 0.6" (124mm x 17mm), the slim, pen-sized form factor is identical in shape and size to a real highlighter — making it the ultimate stealth 510 battery for discreet everyday use. If you're looking for a fun, functional, and genuinely undercover cartridge battery, the BIGFUN! High-Lighter delivers on every level.
