400W Car Power Inverter - Dual DC 12V to 110V AC Car Plug Adapter Outlets, Fast Charging USB C 65W & 24W Port, Power Inverters for Vehicles, Laptop Car Charger, Road Trips

I recently got the 400W Car Power Inverter for my car, and it’s been super handy for road trips and on-the-go charging. The dual DC 12V to 110V AC outlets are perfect for charging my laptop and other devices while I’m on the road. It’s also great that it has two USB ports, including a fast-charging USB-C port (65W) and a 24W port, so I can charge multiple things at once.The inverter itself is pretty compact and doesn’t take up much space, which is a huge plus when you’re limited on space in the car. It works well overall, and I’ve been able to charge my laptop, phone, and other electronics without any issues.That said, it could use a little improvement in the cooling department. It can get pretty warm when running multiple devices, so I try not to push it too hard. Also, the fan noise is a bit noticeable when the inverter is under load, so if you’re sensitive to sound, it might be a little annoying.Overall, it’s a solid power inverter that works well for road trips and keeping devices charged, but improving cooling and reducing noise would make it even better.

We needed to charge some batteries on our way to a baseball tournament and I was so glad I had this! It connected seamlessly to my vehicle and powered up instantly. Having the ability to plug in an actual plug, rather than just a USB or USB-C is awesome! There are so many things we need to use this for, and the only 140v plug I have is way in the back. It’s small enough to store in the glove box and awesome to have on hand when needed!

I work from home so sometimes when I'm traveling, I'm also working so having this adapter in order to plug in my laptop while on the road is a plus. It's fast charging and I no longer have to make "charge stops" while traveling. Great price point!

Works as it should made out of metal for durability only thing I don’t like is it does not having mounting holes or brackets

It plugs right into the car’s DC outlet and starts working immediately. I was impressed with how quiet it runs, and the built-in cooling fan keeps everything running smoothly without overheating.

I haven’t fully used it yet since we’re in the middle of moving, but I got this inverter specifically to power my Mac mini while using Vision Pro on the go. I tested it briefly and it works fine for basic charging. Love that it has USB-C PD 65W — super handy for Apple devices. Can’t wait to get everything set up and see how it handles full usage!

I had a previous review about finally getting a successful '400w' inverter that can supply a reliable 300w.The very next day, the inverter just beeps/chirps constantly while it repeatedly turns on and off.While doing benchmark tests with a gaming laptop that draws around 300w. It worked for 3days of testing. Fairly reliably, but that was a false sense of confidence. By day 4, the inverter was at a total malfunction barely able to hold stable power.I'd give it another try but I pretty sure the capacity of these inverters are simply overstated.In my book, these are junk. Not reliable, it can barely handle 70-80% of its stated capacity before it gives up.On to try another small factor 400w inverter.

This inverter is a lifesaver for road trips and camping. Converts 12V to 110V smoothly with no issues. Powers laptops, chargers, and small appliances with ease. Dual outlets and USB ports are super convenient. Compact size fits easily in the glove box. Reliable, quiet, and exactly what I needed!
