Product advantages--

  1. Open cooling system

Using heat sink anodic oxidation technology, the temperature can be radiated to the outside stably and safely.


  1. Function of drop protection function

Any cable disconnection can protect the battery from no output.


  1. High-quality MOS tube is impact resistant and has low temperature rise.

Brand-new high-quality low internal resistance MOS tube, multiple optimized protection management schemes, stably reduces the internal resistance of the circuit and prolongs the service life.


  1. Brush the three-proof paint, multiple protections, to ensure safety and reliability.


  1. Smart chip!

It is carefully made with good components to achieve a series of functions such as long service life, strong endurance, and low charging and discharging temperature.


  1. The layout is clearly visible!

The inside to the outside of the protection board is intuitively visible, and each part can be clearly understood.
