• Always tighten the Positive (+) and Negative (-) terminals when the inverter is in use otherwise a loose connection can overheat due to poor contact.
• Always make sure that the total rated power of the connected devices is less than 400W.
• Avoid placing the inverter in a location that receives prolonged direct sunlight or near to heat sensitive materials as the inverter can become warm during use.

We use it to run our electric blanket in our camper for about 30 minutes to warm up the bed. I generally use the charger in my truck. The inverter is really nice for traveling.

The first time I receive the item, it doesn’t work because of my wrong installation. The Bestek customer service team is so friendly, they helped me to handle this problem and really love the USB ports. Everything goes well.

I was so happy Bestek stood behind their product because I had shopped around for other inverters but none had the two AC plugs and the 4 USB ports. Great unit. Thanks, Bestek.

I found this to be a very high quality and rugged inverter. I like that it had USB ports, replaceable fuses, an indicator light, and several cable connectors. Nice item at an affordable price.

I was looking for an inverter for a travel trailer to power a 200W AC refrigerator on the road. I have it installed in and it worked well. The USB outlets are a great addition as well. Love the item.
