Thank you for viewing. This is a 1200W pure sine wave inverter with a remote control. - Model: 1200W-DC12V-AC100V - Output Waveform: Pure Sine Wave - Brand: DATOU BOSS - Accessories: Remote Control I have confirmed that a 1000W hair dryer works with my setup (165G51 battery and 8AWG battery connection cable x 1M). This product may not function properly if the battery capacity is small or if thin cables are used. (For example, errors will occur if 12V is supplied from a car's cigarette lighter socket with a cable of about 1.25sq.) I hope that those who understand this will purchase it. Since it is a used item, basically no returns or refunds are accepted. * The terminal cover and battery connection cable for this unit are missing. We look forward to your consideration.
