Key Features 400W of continuous power. Maximum charging power of 800 W. Anodized aluminum casing provides durability and maximum heat dissipation. Integrated cooling fan. External 30 amp fuses, replaceable. 12 volt cigarette lighter socket 220 volt/50 Hz power outlet (EUROPEAN OUTLET) Overload indicator On/off switch. Specifications: Output Waveform: Modified Sine No Load Current Draw: <0.1A Efficiency: up to 90% Input voltage range: 10-15 VDC Surge shutdown: more than 15 VDC Low voltage shutdown: less than 10 VDC Low voltage alarm: audible at 10.6 VDC Overload shutdown: Yes Short circuit shutdown: Yes Thermal Shutdown: Yes. AC Receptacle: 2 Single Pins Dimensions (L x W x H): 7.40 x 2.0 x 5.0 in. Weight: 4 pounds Review: Only had a 174 VAC output rather than the 220 as stated. - Arrived quickly however the output voltage was only 174 VAC rather than the 220 is supposed to be. Lucky I checked the voltage before plugging in anything. I though maybe the voltage regulator was not sensing a load but I disproved that when I connected two 40 watt, 110 volt light bulbs wired in series to provide a 80 watt 220 volt load.The output still remained low at 164 vVAc and the inverter started chirping. The DC voltage input was good at 13.5. I did not bother to put my frequency meter on it to see if it put out 50 Hz. Also had this voltage booster/inverter a slight smell of a burned semiconductor. I turned it off quickly as the User Guide that comes with it states the chirping indicates a problem with the device. I had this hoped product would have worked properly, quite disappointed. :( Review: Not in love, but we have limited options for producing 50Hz ... - It does work, but it tends to smoke and stink some whenever you use it. I am largely not using it as a result of this issue. If you get near the rated power of 400W, it shuts down. 300W is safe I would say. It also doesn't produce a sine wave output (it produces a three step signal). Not in love, but we have limited options for producing 50Hz power cheaply. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0016L2UHS | | Brand | PowerBright | | Customer Reviews | 1.6 out of 5 stars 3 Reviews | | Efficiency | 90 | | Frequency | 50 hertz | | Input Voltage | 12 volts | | Manufacturer | Power Bright | | Mfr Part Number | ERP400-12 | | Model Number | ERP400-12 | | Output Power | 800 watts | | Output Voltage | 220 volts | | Power Source | 220v | | Standby Power Shutoff | 90 | | UPC | 841915000200 | | Wattage | 4400 watts | ## Product Details - **Brand:** PowerBright - **Power Source:** 220v - **Wattage:** 4400 watts - **Input Voltage:** 12 Volts - **Output Power:** 800 Watts ## Images ![PowerBright ERP400-12 400W 220V/50Hz 12 Volt DC Power Inverter, 4400W Continuous Power, 800W Peak Load Power Rate, Anodized Aluminum Case, Built-in Cooling Fan, Power ON/OFF Switch - Image 1](https://m.media-amazon.com/images/I/91jx9s7gORL.jpg) ![PowerBright ERP400-12 400W 220V/50Hz 12 Volt DC Power Inverter, 4400W Continuous Power, 800W Peak Load Power Rate, Anodized Aluminum Case, Built-in Cooling Fan, Power ON/OFF Switch - Image 2](https://m.media-amazon.com/images/I/91cpDFJKIfL.jpg) ![PowerBright ERP400-12 400W 220V/50Hz 12 Volt DC Power Inverter, 4400W Continuous Power, 800W Peak Load Power Rate, Anodized Aluminum Case, Built-in Cooling Fan, Power ON/OFF Switch - Image 3](https://m.media-amazon.com/images/I/91KQkhxXRwL.jpg) ![PowerBright ERP400-12 400W 220V/50Hz 12 Volt DC Power Inverter, 4400W Continuous Power, 800W Peak Load Power Rate, Anodized Aluminum Case, Built-in Cooling Fan, Power ON/OFF Switch - Image 4](https://m.media-amazon.com/images/I/71ESrNMP2HL.jpg) ![PowerBright ERP400-12 400W 220V/50Hz 12 Volt DC Power Inverter, 4400W Continuous Power, 800W Peak Load Power Rate, Anodized Aluminum Case, Built-in Cooling Fan, Power ON/OFF Switch - Image 5](https://m.media-amazon.com/images/I/71N+fGyImHL.jpg) ## Customer Reviews ### ⭐ Only had a 174 VAC output rather than the 220 as stated. *by R***D on February 16, 2017* Arrived quickly however the output voltage was only 174 VAC rather than the 220 is supposed to be.
