Double LED digital display.  2. Aluminum-alloy shell, light weight, good thermal conductivity, can quickly reduce the temperature of components, work long hours are not affected.  3. Using chip technology, high reliability, seismic resistance, solder joint defect rate is low, reducing battery and radio frequency interference.  4. Eight intelligent protection, overload protection, high voltage protection, low voltage protection, over temperature protection, reverse polarity protection, short circuit protection,Overcurrent protection,Insurance protection.  5. Pure sine wave, smart filter, no interference on the electrical, to protect electrical appliances.  6. Up to 93% conversion rate, reduce the conversion loss of 30%, increase 30% continuous power.  7. High-precision circuit board.  8. Built-in intelligent control chip.  9. Intelligent temperature control fan, make the inverter more quiet. When the temperature ≤ 45 ℃, the fan stops working, when the temperature ≥ 45 ℃, the fan began to work.  10. Buzzer reminder device. Once any protection of the inverter is triggered, the inverter immediately disconnects the power supply and the load enters a protection mode and reminds people through a buzzer reminder.  11. Screw terminal. Pluggable plug, easy to replace the cable.  12. Dual cooling fans to extend the life of the inverter.  13. Universal three-hole socket, strong compatibility,most appliances are suitable.  14. Low standby power consumption, high conversion rate.  15. Intelligent chip control, complete protection.     Package Included:  1 X Inverter.  1xUser Manual.  1xUltra-thick Battery Cable
