Review: Great inverter - Works well.
Review: Useful and reliable - I've had this inverter for over 9 years now, taken it on multiple cross country trips, including ones that have involved car camping where this was our only source of 110 AC power for days at a time. I originally bought it after such a trip where we found the 1 amp USB slots that were factory-installed in our SUV didn't put out enough juice to recharge my wife's iPad while she used it, or even get it to a full charge in a reasonable amount of time when she wasn't using it. Since then this inverter has powered laptops, portable DVD players, iPads, and phones, often all at the same time, while providing steady power and not overheating, thanks to its built-in fan. I think the few people who have had problems with this are either trying to use it with devices that draw too many amps, and/or their car's electrical system is limited and not designed for such an inverter (see further explanation below. So my advice is: 1. Stick to the devices it (and your car's electrical system) were designed to provide power for, and avoid amp-hungry appliances like power tools and coffee makers I've seen mentioned in the low reviews (SMH). 2. Check the specifications of your car's electrical system and its output from its cigarette lighter outlets before you buy this inverter, and before you jump to blaming this inverter when things go wrong. Car cigarette lighters are practically never designed to be on a circuit all by themselves, and depending on the car model the cigarette lighter could be on the same circuit only with low-draw components like dashboard lights and overhead interior lights (many of which would not necessarily even draw current at the same time that often), or it could be on the same circuit as a high-draw component like, say, your car's air conditioning system. That is going to make a big difference as to how much additional load that circuit your cigarette lighter is able to handle, and thus will affect what you can plug into the inverter. I personally have used this in a 2011 Toyota Venza, 2011 Chevy Malibu, 2017 Mazda 6, and a rental in 2016 that was either a Chevy Tahoe or GMC Yukon, and again, never had any issues in any of these cars, but other vehicles (including newer generations of these same models) may have the issues I mentioned above.

## 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.

### ⭐⭐⭐⭐⭐ 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.
