Features: 1. Multiple protection, core technology: using advanced technology design / more durable load / not easy to burn the machine. 2. New imported materials for the shell: drop-resistant, wear-resistant, durable, and extend the service life of the power supply. 3. The inner core is 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 visible. 4. Encoder adjustment, no need to short-circuit directly preset voltage and current. 5. Intelligent temperature control fan: When the internal temperature of the power supply reaches a certain temperature, the fan automatically dissipates heat.
