    Funciona perfecto, muy útil para emergencias

    Este inversor de corriente para carro es excelente. Convierte la energía de manera eficiente y permite cargar varios dispositivos sin problemas. Es compacto, fácil de usar y perfecto para viajes o emergencias. Además, tiene buena potencia y no se calienta demasiado. ¡Definitivamente una gran compra

    Works great

    This worked great to blow up an inflatable air mattress for a camping festival. Also used it to charge a usb chargeable lantern.

    YES it does power my laptop no problem

    was skeptical that it would not power my laptop since its not a pure sine inverter – but YES it does power my laptop no problem – I like it – small package that puts out a lot of power and very quiet!

    Nice unit

    Quality seems good it’s smaller in size then I thought it be but it seems to work great. I’ll update at a later time as to its longevity.

    Fry, baby fry!

    The AC outlets work properly. The first time I used the USB port, it immediately fried my phone charging port. The documentation states the output is at 4.2 AMPs yet the device states 2.4 AMPs. Flip a coin,or just don’t use the USB ports.

    Terrible

    Quite literally stopped working on the very first attempt to use AND blew my mini soda fridge. Minus one star

    Good, but plug broke

    Works great, but would like plugs to be spaced better so you can plug in two USB converters at once. Would like USB c plugs since that it what everything is going towards. The plastic on the plug broke so I threw it away. Not sure if it is the quality or if any plug would have been broken from my kids repeatedly kicking and hitting it with things.

    Didn’t work with ’18 Camry or ’21 Highlander

    Purchased to use in our family vehicles, a 2018 Toyota Camry and 2021 Toyota Highlander. Both vehicles are stock, nothing added to draw on the power of the cigarette lighter-type plugs. However neither vehicle was able to power this AC inverter for more than 1 or 2 seconds. Lighter would turn on and power up, then abruptly fail.

    Use it to power any laptop or tablet in your car

    I was looking to buy a 12v to 18.5v power adapter for my HP laptop so I could use it in the car, but this was cheaper and I can just plug any laptop power cord into it. Very solid construction, a bargain!

    Don’t buy

    Every time you plug in something it blows the fuse in your car for your cigarette lighter that you use to power this thing. Cheap junk. Just by regular power pack instead
