ZJKC PMW2500 2.5W 650+808+905+980nm massager

Cold laser therapy wavelengths

The ZJKC PMW2500 is a handheld cold laser therapy device that emits four selectable wavelengths: 650 nm, 808 nm, 905 nm and 980 nm. It delivers adjustable power up to 2500 mW for low-level laser therapy treatments. The unit weighs 0.47 kg and measures 24 cm by 7.5 cm by 7.5 cm. A 3400 mAh rechargeable battery and an AC 100-240 V adapter power the device.

Home users seeking drug-free pain relief

This massager suits adults who want a portable, non-invasive option for managing muscle pain, joint stiffness or minor injuries at home. The included UV goggles protect eyes during short treatment sessions. Buyers who need a clinical-grade system with larger treatment heads or preset protocols for specific diagnosed conditions should look at professional equipment instead.

Adjustable power output up to 2500 mW

The single specification that determines suitability is the maximum adjustable power of 2500 mW across the four wavelengths. This level supports superficial and deep tissue penetration for the indicated therapy times of 1 to 180 seconds per session. If a prescribed treatment requires higher irradiance or a different wavelength set, this device will not meet that requirement.
