Portable Cold Laser Therapy Device
The ZJZK Standard unit combines 16 diodes at 660nm with 4 diodes each at 810nm and 980nm for a total of 24 diodes. It delivers 1760mW of low-level laser output across red and near-infrared wavelengths. The device is designed for home use by adults seeking photochemical pain relief without thermal effects.
Battery Life and Silent Operation
Each full charge provides 6 to 8 days of standby and use time, and the unit can operate while connected to the 110V AC adapter. Low-level laser therapy produces no heat, so the device runs silently with no fans or moving parts. Power draw is limited to the charging cycle and the 1760mW optical output during treatment sessions.
Compact Build for Direct Skin Contact
The lightweight, portable housing fits in a bag for home, office or travel use and is intended to be applied directly against the skin. The package includes the therapy device, an 110V AC adapter with charge cable, protective glasses and a user manual. It is not suited for users who require hands-free wearable operation or battery hot-swapping during extended daily sessions.

Questions about this item
How do I position the 24 diodes against the skin for treatment?
Place the device directly against the skin over the painful area; the 16 diodes at 660 nm and 4 each at 810 nm and 980 nm emit light that must contact the surface to penetrate effectively.
What parts will need replacement after repeated use?
The built-in rechargeable battery is the only consumable; after many charge cycles its capacity will drop below the 6–8 day runtime and the unit will require service or replacement.
How long can I run a continuous session before the 1760 mW output drops?
A full charge supports 6–8 days of typical use; during a single session the output remains stable until the battery depletes, at which point you can continue while plugged into the 110 V adapter.
