This mining light is designed based on many standard . small ,light ,convenient to carry,long using life,high lighting, fast charging,etc.
If the main power source is broken,the other secondary source would provide more than 30 hours light source.

Main technical parameters
Rated voltage:3.7V

Rate capacity: 4Ah

Lighting hours:>19

Max lighting distance:at beginning:>3000 lx; after 11hours: >2500lx

The life span of storage cell: >500 times(charge-discharge cycle number.)


The characteristic of LED light source:

Using low voltage power source to make safe; low power wasting; high stability; much short response time and pro-environment.
