BESTEK Pure Sine Wave Inverter 300W MRZ3010HU I had this in my car. I only connected it once for a test when I bought it. I'm selling it because I got rid of the car. It's dented to some extent, but I will send it in the original box. As shown in the photos, I will also send the battery cables. For more details, please see: http://www.bestek.co.jp/item/products/products01/2046 I purchased it in 2018.
