Handheld Cold Laser Therapy Device

The ZJZK HHL02-724 is a handheld cold laser therapy device designed for adults seeking non-invasive pain relief at home or while travelling. It delivers three distinct wavelengths to address surface discomfort, muscle tension and deeper joint pain. The unit is unisex and intended for personal use.

Rechargeable Lithium Battery Operation

A built-in 3600mAh lithium battery powers the device for up to seven days of typical use between charges. The included AC adapter accepts 100V-240V input, so the device can be recharged worldwide without a separate transformer. A portable handbag holds the device, protective glasses, adapter and manual together for easy transport.

Silent Continuous and Pulsed Modes

The therapy head contains 24 GaAlAs diodes producing a total optical power of 1760mW. Users select from four power levels at 25%, 50%, 75% or 100% and choose continuous-wave or 10Hz pulsed-wave operation. Session length is adjustable from 1 to 60 minutes, and the device runs silently throughout treatment.

What comes in the carrying case for travel and home use?

The kit includes the handheld device, protective glasses, an AC adapter covering 100 V–240 V, and a user manual inside a portable handbag.

How do I set a session without skipping the eye-safety step?

Choose one of four power levels (25 %, 50 %, 75 %, 100 %), set the timer from 1 to 60 minutes, pick continuous or 10 Hz pulsed mode, then put on the supplied glasses before starting.
