A:In domestic market, the high and low inverter brands are mixed together. There are many low-cost power inverter is actually some assembled small unlicensed workshops,crudely  to reduce costs and use of substandard components for assembly, there is a very big security risk! In order to protect the pro personal and property safety, please do not covet low  price, be sure to choose a reliable inverter! 2,Q:Is the output voltage of our inverter stable ? A:Absolutely. Our inverter is designed with a good regulator circuit. You can even check it when measuring the true value by a multimeter. Actually the output voltage is quite stable. Here we need make a especial explanation : many customers found it is unstable when using conventional multimeter to measure voltage. We can say the operation is incorrect. Ordinary multimeter can only test pure sine waveform and calculate datas. 3,Q:What is a resistive load appliances? A:Generally, appliances like mobile phones, computers, LCD TVs, incandescents, electric fans, video broadcast,  small printers, electric mahjong machines, rice cookers etc. All belong to resistive loads. Our power inverters can drive them successfully. 4,Q:What is the inductive load appliances? A:It refers to the application of electromagnetic induction's principle, produced by high-power electrical products, such as motor type, compressors, relays, fluorescent lamps, electric stove, refrigerator, air conditioner, energy saving lamps, pumps, etc. These products'power are far  Customer Feedback /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
