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?
The descriptions and photos here show TWO(2) AC Outlets, but some reviews say it only has ONE(1). Which is it?
Will this drain the car battery and does the car need to be running to use this?
Will this work with/charge a 15 inch Macbook Pro?

Overall Great Product!

Worlds great! I have purchased two of these for both my personal and work vehicles! It is a slim fit, supplying adequate power without taking up too much space. The on/off switch allows you to cut power without killing your battery, with a green light to alert you that power is on. Two AC outlets, one USB, and one Type C for all charging needs. Only complain that that the two AC are too snug together to fit two bigger 110 plugs, but I usually use one at a time anyways!

Good item

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.

Works wonderfully-check the specs

We have had two of these inverters since 2021. I’m sure we would have the OG one but I tried to charge my gaming laptop with it without checking the capacity and fried it (my bad). We quickly bought a second one though. It’s quiet, charges the iPad fine and can charge my kids school chrome books on the go. It’s super helpful for long car rides. We plug it in the AC plug in the trunk of the van so the kids can charge their devices back there and my husband and I just use a mini plug up front for ours. Highly recommend this.

She was good til she died

She lasted me a good 4 years before the plug broke. Only complaint was the outlets are too close together so I couldn’t put 2 Apple chargers together. But worked well!

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.

Perfect

I bought this item to power my mobile printer/scanner, and it works perfectly for my needs.I’m a mobile Notary and I have to scan every document and send them to my clients, after I finish a closing.This unit has no problem handling the printers needs.

Powers small medical devices

Works well to power my wife’s medical device when driving. Like two UBS ports.

11 Years And Still Going Strong! Excellent Purchase

I bought this back in 2014 and it is still going strong. I work from my car and have used it 5 days a week since then. Excellent investment. Charges my laptop all day, runs my portable printer and the USB ports have been used for all kinds of electronic items. I have accidentally dropped it a couple of times and the metal case has held up with no problems. Simple plug in to use. The cord length has been great. Not too long and in the way, but long enough for me to tuck it away. Definitely well worth the investment for 11 years of use so far.
