Peak power: 300W Continuous power: 250W LED Battery Power Display Input voltage: 12V Output voltage: 220VAC Dual USB output: 5VDC/2.1A No load current: 0.5A Conversion efficiency: greater than 90% Protection: overload, over temperature, high pressure, low pressure, reverse connection and short circuit intelligent temperature control, less than 300W (except for the inductive load electrical appliances and electrical products) 1. Please try to use our standard battery cable, otherwise it will not be able to output enough power 2. Turn on the inverter; turn it on first and then turn on the load. Shutdown: Disconnect the load first and then shut down. 3. It is strictly forbidden to connect the mains to the output port, and it is strictly forbidden to reversely connect the battery with the load. 4. Do not overload household appliances, such as inverters with inductive loads such as motors, water pumps, air conditioners, etc., please multiply the rated power by at least 3 times, and the obtained value should not exceed the inverter power. 5. The red light of the inverter is on and there is a buzzing sound. Please check whether it is overloaded and whether the battery is fully charged (regardless of whether your battery is a new battery or not, please charge the battery for at least 3 hours and try again. 6. When the inverter is not in use, please turn off the inverter switch. 7. When the inverter beeps, be sure to disconnect the load first, turn off the inverter switch, and then check for the problem.
