Customers are saying

Customers are impressed with the power output and overall performance of the POWER 500 Watt Power Inverter, especially noting the effectiveness of the USB charging ports. The device is also appreciated for its ease of use in smaller vehicles and reasonable price. However, some customers have reported concerns about excessive noise and, in a few instances, a strange smell.

    This is a great product to have for use inside the vehicle while driving. It powers up my laptop, printer, and charging my cellphone and Ipad all at the same time. A "Must-Have" item in the vehicle. KL

    Bought this portable inverter to power the rv and fans in my RV. After reading reviews on many, I liked what I read and saw on this model. Perfect for my needs. Comes with both battery clamps and lighter plug.

    I was unable to use this. I only needed it to plug my laptop in while in the car. It couldn’t handle my laptop and alarmed very loudly. When the alarm finally stopped it smelled so bad I unplugged it.

    The device works, but the plug-in to use it with your vehicle's 12V "cigarette" port is too wide and long -- it can be used but the slightest bump or wiggle will cause it to fall out, or it will gradually come out over time. Whenever it does, the device beeps really obnoxiously loud for losing power. It is not just a problem with my car -- i checked it in 3 ports in an SUV and 1 port in a Sedan; same issue in all. Unreliable and would not recommend this.
