Powerful USB Blue Laser Pointer 3500mW with Multi-Mode

The output power I measured was 3200mW, not the advertised 3500mW.

This price includes many accessories, such as a USB charger, 26650 batteries, pattern heads, etc. It is definitely worth the money!

Besides the super high power, what I like most about this product is the OLED screen, which allows me to view the parameters (voltage, current, power, and operation mode) in real-time.
