After several months of testing and development, we released this blue laser pointer (from the Sanwu series) in August 2025. It features a unique square-shaped housing and an optional Bluetooth function. Despite its compact size, the blue laser beam is powerful and stable (if you choose the Bluetooth version, you can adjust the output power and output mode via the app). If you are looking for a small and professional laser pointer, it will exceed your expectations.
Package Type
1) Without accessories: includes only the laser pointer.
2) Standard package: Sanwu laser pointer + one 10440 battery + charger + storage box.
3) Professional package: Sanwu laser pointer + two 10440 batteries + charger + safety goggles (OD4) + storage box.
Bluetooth Functionality
After turning on the laser pointer, press the Bluetooth button in the top right corner to connect it using the Bluetooth App. You can adjust the output power and mode speed via the App. Additionally, you can program the operation and save your custom settings. Bluetooth functionality for lasers is a major technological breakthrough for us in 2025!
Incredible Power-to-Size Ratio
This laser pointer is quite compact and can be powered with just a single 10440 battery. The output power reaches up to 800mW. Even in a collimated state, the laser beam can easily burn objects without requiring focusing. The power-to-size ratio will exceed your expectations.
Two Switch Buttons
It's equipped with two side buttons for users to easily control power and mode switching. Users can even customize the function of each button (add operation combinations) using the mobile app.
Adjustable Power
After turning on the laser pointer, you can press and hold the B button to adjust the output power.
Built-in Buzzer
You can press and hold button A to hear the buzzer sound. If you selected the version with Bluetooth, you can also adjust the buzzer volume (or set it to vibration mode).
Unique Square Design
The housing features a square-shaped design made of military-grade stainless steel. It is compact, sturdy, and durable. You can easily slip it into your pocket for convenient carrying.
Beam Divergence Angle
The beam divergence angle of this laser is relatively low. The laser beam is thin and powerful. If you choose the 800mW output power, it can light matches from a long distance.
Internal Protections
This model has multiple internal protections, including PCB protection, overheat protection, and reverse polarity protection.
Waterproof Design
With a seamless design and built-in sealing rubber rings, it offers reliable waterproof protection.
Heat Dissipation
The full-metal housing helps with heat dissipation. However, due to its compact size, this model does not include a temperature control chip. After continuous operation for 60 seconds, please allow it to cool down for 30 seconds.
One-Year Warranty
As one of the world's leading laser manufacturers, we always adhere to the one-year warranty policy. However, obvious intentional damage is not covered by the warranty. All products are tested before shipment, and the packaging is secure and reliable. There are no customs fees or additional charges.
Buying Tips
1) We will send the silver style by default. If you need the golden style, please contact us before purchasing. The gold style requires additional customization fees.
