## Questions & Answers

**Q: When I plug my laptop into it, and then play music through my laptop I get really bad cyclical sound ... is there a way to filter this out?**
A: I'm going with audio engineer dude on this one. But really what I wanted to address, is people saying it's due to it being a modified sine wave. That's not your issue. Laptops don't run on AC, they run DC, so first off sine type isn't an issue. Second, anything not straight off the main grid or a generator is a modified sine. There are better and worse, but if you're going DC to AC, it's modified sine. In all honesty though, if you're running a laptop off an inverter, the best thing would be to see if you can adapt straight from your original source to a laptop charger, bypassing the whole AC conversion.

**Q: The descriptions and photos here show TWO(2) AC Outlets, but some reviews say it only has ONE(1). Which is it?**
A: The unit that I received has 2 110v outlets and 2 usb ports. The unit was used on a recent trip to Texas and worked flawlessly.

**Q: Will this drain the car battery and does the car need to be running to use this?**
A: It depends.  If you have an ICE car with an internal combustion engine and a small "starter/ignition" battery, you won't want to run anything more than a few hours, maybe less if your battery is older or you've run it to dead a couple of times already.

But for my electric car, I've used a small inverter in the accessory jack to power small things for up to a week, and hardly noticed it.

**Q: Will this work with/charge a 15 inch Macbook Pro?**
A: Yes it works very well,  and runs quietly.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Car Power Inverter
*by R***Z on August 28, 2025*

This inverter is amazing. You can convert your car’s power to 110V in a second and charge your laptop and phone at the same time thanks to its USB-C and QC3.0 ports. I feel at ease knowing it has protection against overload, short circuit and overheating. Plus it’s super easy to install. I recommend it to anyone who travels a lot, works outdoors and needs to charge multiple devices without issues.

### ⭐⭐⭐⭐⭐ Good item
*by J***Y on June 23, 2025*

I ordered this for my husband car, seems like I'll be ordering a second one to put in his other car as he like it very muchSuper quiet and functions well. It fits in his center console of his Lexus car, it was definitely worth the money paid. He uses it to charge his phones and uses the plug. It charges them up pretty quickly- way faster than that cigarette plug thing.

### ⭐⭐⭐⭐⭐ All in One Device: Value, Consumption, Great Voltage
*by J***4 on May 31, 2025*

I finally judgement day has come for this power supply car charging device! And I must say it has surpassed my expectations. The night I made the purchased man did I look at a lot of products and read a lot of reviews. There was a lot of mix feelings and I had narrowed it down to this product and another brand. I decided to take a chance with this one as it was about a couple of bucks less. And I am so glad I took the chance. Not only did I get a good bang for my buck. This sucker has endure a couple of water spills! The value of the product is definitely worth it even though I can't afford to dish out. Lol totally worth it for how I have abused it. 😬 So durability checks out great. The power consumption is amazing. I have been able to keep my laptop alive. Not able to charge the battery but at least I can turn it on to use it and do what I need to do quickly. And I can use my super charger for my phone and I love how it has two wall outlets and two USB connections.
