Ampeak 750W Power Inverter 4.8A Dual USB Ports 2 AC Outlets Car Inverter DC 12V to AC 110V 11 Protections for Appliances

Wish I still had this device it was lost in crash works absolutely fantastic would definitely recommend getting this device I used it a lot working wild fires to power my radio chargers and light chargers never over heated or anything worth the money

This 400W inverter is absolutely amazing and works perfectly. It’s powerful, reliable, and very easy to use. I’ve tried many others before and this one is by far the best. It runs everything I need without any issues and feels very well made. Great value for the price and definitely worth it. Highly recommend!

Great unit! Used for running and TV at a football tailgating party. Only wish is that the leads to connect to battery and into accessory receptacle were longer. Overall, it worked perfectly.

As described in photos

Very stable, very helpful, and doesn't make any noise or beep during use. I use it when I need to work on my laptop for several hours inside the vehicle, and it responds very well.

I bought this inverter to provide 110 vac power in the event of a power outage. I particularly like the flexible approach the designers have used to provide 12 vdc power to the inverter. The unit with comes battery clips for connection directly to a 12 vdc battery for high power output, and a cigarette lighter plug for low power use. There are two grounded AC outlets and two USB connectors for charging smartphones, tablets, and the like. Connecting directly to the battery terminals allows maximum AC output as the clips and their short wires can handle the high dc current needed to produce maximum rated output. The cigarette lighter plug is rated to be used at under 120 watts AC for extended periods. I wired a third power connection option, shown in the picture. This cable allows connection to my DC power source with its Anderson Powerpole connector. This will easily handle the 360 watt limitation of my DC source. The device itself has a useful on-off switch and LED indicator showing that it is ready. By my measurement, the unit used under 5 watts without load, about 0.4 amperes at 12 vdc. There is a rear-mounted fan to cool interior components during periods of heavy usage. I have used the unit only for limited testing, but if it is as rugged internally as it is well designed externally, I expect to be pleased with it overall.

It worked just great on our trip

I bought this and used it sparingly for 3 months, mostly using the USB ports to charge phones. When I plugged in a laptop, it the 3-prong outlets stopped working. The outlets were not even capable of charging a normal laptop. The manufacturer apparently thinks the inverter might not be capable of charging a laptop through the car outlet, which just about any inverter should be able to do. They had me hook it up to the battery to see if the laptop was drawing too much power, which was silly. They also said the outlets probably broke from overuse, which is ridiculous because I barely used them and only charged cell phones on them unit I tried my laptop, and I only had the inverter for 3 months. Also, after awhile, the plugs would work to charge cell phones but not the laptop, which shows this is a defective item incapable of charging a laptop. The company claims to have a "hassle-free" 18-month warranty. They also claim to have "100% customer satisfaction," which is essentially impossible and also false based on reviews. To get them to acknowledge a warranty claim, I had to spend time making videos showing how the outlets did not work with my laptop and also had to connect the device directly to the battery, which I never do. They customer service responded quickly, but after I did that, they told me to contact Amazon to make a claim on their manufacturer's warranty. Amazon does not take those claims. Amazon only accepts the return within 30 days. So after the 30-day window, the warranty essentially is up. I talked to three different Amazon chat people. The first person said I could return it if I paid a 20% restocking fee, which makes no sense for a defective item. The second person said to contact the manufacturer again. The third one said they would give me a "one-time exception" and refund me. Amazon sucked up the refund, not the manufacturer. So if you actually want to make a warranty claim, you probably have to get lucky with the customer service representative and may have to try several of them.

Lo uso cuando se va la luz en la casa y concertó una extensión del inversor a un contacto de la casa, bajando las pastillas y ya tengo luz en mi casa. Ojo no para minisplit ni refrigerador.. solo focos, abanico e internet

Gran producto, llego a tiempo, no estaba maltratado el empaque, funciona muy bien y no hace mucho ruido al encender, recomendado ampliamente.

Llegó muy bien, y funciona súper bien. Los materiales se sienten resistentes y de buena calidad

Este inversor cuenta con un diseño ergonómico, es muy ligero y se siente de fabricación robusta. Cuenta con 2 puertos USB y dos salidas corriente, además un switch de encendido. El mío viene en una caja de impresión a una tinta negra (aquí se nota la reducción de costos). Viene contenido el cable del encendedor el cual se conecta al inversor removiendo dos bornes, colocando las terminales y sujetando los bornes, lo cual no recomiendo, dado que el inversor trae 3 fusibles de 35A. En el momento en el que le exijas consumo, seguramente va a quemar el fusible del encendedor de tu auto por superar la capacidad, ya que en su mayoría, son de 15A o 20A. En su caso, yo conecte las dos pinzas, cuidando colocar correctamente su polaridad, y lo conecté directo al acumulador, sólo hice una prueba de funcionamiento con un ventilador de pedestal. Funcionó adecuadamente las 3 velocidades. Dejo este comentario hasta aquí, si más adelante surgen novedades, con todo gusto edito el comentario.

Funciona bien para dispositivos que no usen más de 100W. Por el precio me parece bien, pero dice ser de 400W, y cuando conecté un reflector de 300W no le dio la potencia suficiente. Lo probé con diferentes autos, incluyendo una camioneta Cadillac, con ninguno funcionó para 300W, ni siquiera conectando el transformador directamente a la batería.
