Features: Multiple protection, cores technology: using advanced technology design / more durable load / not easy to burn the machine. New imported materials for the shell: drop-resistant, wear-resistant, durable, and extend the service life of the power supply. The inner cores are newly upgraded: the material is sufficient, the circuit design is reasonable, the power output is guaranteed, each original is kept improving, and the meticulous craftsmanship is evident. Portable Encoder adjustment:no need to short-circuit directly preset voltage and current. Intelligent temperature control fan: When the internal temperature of the power supply reaches a temperature, the fan automatically dissipates heat.
