4. Notice: This board is a high-frequency square wave AC output, so general inductive appliances cannot be carried! ! (Such as: electric motors, electric fans, coil , etc. cannot be used directly) Another: Simple resistance-capacitance step-down small electrical appliances, cheap resistance-capacitance step-down LED lamps, etc. may not be used 3. You can use electrical appliances: lamps, non-inductive household appliances, small electric rice cookers, (note: support all ''electronic products'') such as: -saving lamps/solder/switching power supply/satellite TV receiver/bulb/ LED lamp/LED -saving lamp/fluorescent lamp/DVD player/VCD player/EVD player/LCD TV/color screen TV/flat screen TV/notebook/computer/various computer monitors/all electronic charger products/etc. 1. High efficiency, , low power consumption, convenient and safe to use, saving and , widely used in , night camps, night market vendors, driving and family power outage emergency helpers 2. It can be used as the front-stage boost inverter circuit of pure sine wave, modified sine wave, single-silicon machine, and four-silicon machine. For electronic enthusiasts DIY production, maintenance and replacement, manufacturers control cabinet supporting products and so on. 5. Many multimeters that output high-frequency square-wave AC voltage cannot measure or display low and high levels (it is incorrect, not the actual voltage) (can be measured by the multimeter in DC mode after rectification), Weight: 0.48060773116 pounds, Manufacturer: Prterver
