The Challenger is powered by a single 14500 lithium rechargeable battery and weighs approximately 140 grams, making it the lightest handheld laser we've ever produced! Despite its featherweight build, it delivers 10–20 times more power than typical lightweight green or red laser pointers—true high-performance in an ultra-portable package.

 
Rare Laser Wavelengths

Our Challenger supports a wide selection of laser diodes, including rare and exotic wavelengths you won't find elsewhere. Choose from standout options like 1.6W 445nm blue or 1.6W 465nm bright blue for intense burning capability. Optimized for lower-power settings and unique colors, Sanwu Lasers exclusively offers rare wavelengths such as 455nm Royal Blue, 488nm Cyan, 571nm Yellow, and 593nm Amber—perfect for collectors or laser enthusiasts seeking something truly special.

 
Stylish Engraving

Customize your Challenger with two stunning housing styles:

• Standard smooth housing with a clean smooth chassis for a minimalist look.
• Stylishly engraved housing featuring a dynamic tornado swirl pattern wrapping around the upper and lower sections—adding a premium, eye-catching aesthetic to your everyday carry.

Power & Operation Insert one unprotected 14500 lithium-ion battery (positive terminal first), screw on the tailcap, and press the power button to operate. Supports single-mode (full power) configurations, with short duty cycles recommended for higher-power variants (e.g., 30–60 seconds on/off) to manage heat in this compact copper-heatsinked design.

Battery Protection

Built-in safeguards include over-discharge protection, over-charge protection, and reverse polarity protection to keep both the laser and batteries safe.
