I bought the 300W Power Inverter for our family road trips, and it’s been an absolute lifesaver, especially for my wife. It allows her the convenience to use her breast pump on the go, ensuring our little one is always taken care of, no matter where we are. What I personally love about this inverter are the built-in USB-A ports. They’re perfect for charging our devices without needing to juggle extra adapters. The inverter itself is compact, easy to use, and really delivers on performance. It’s made our travel experiences smoother and more comfortable, knowing we can power what we need, when we need it. A must-have for any family on the move!

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.

Wish the cord was a little longer, but it works like a charm. We’ve ran a laptop on it during longer road trips for the kids to watch movies. Charges several devices at once with a pretty good charge time and not overheating.

Looks cheaply assembled, i.e. The USB ports are so misaligned with the metal front plate that it actually scratches whatever USB plug you plug in. Does not have a fuse inside of the cigarette lighter adapter. This broke within a couple of weeks.While it’s still looks cheaply assembled and the USB ports are still misaligned, it turns out the fuse between the lighter socket to the battery went out, so this didn’t actually break when I reversed the polarity accidentally, as I thought it had. I wouldn’t jump to the conclusion that it has reversed polarity protection since it did take the lights down and blew a fuse that I had connected to the socket, but at least it survived the incident which is more than I can say for a lot of other inverters. Once I realized it still works I tested it out with a 100 Watt fluorescent bulb. It passed with flying colors.So the way I see if the pros are these:Provides plenty of power at a very low price 300WattsIt’s a relatively small for the wattage providesDoesn’t seem to have a problem with picky loads like fluorescent lightbulbs, even big ones.Includes two USB portsAnd the cons are:The fan does not kick-in only when there’s a heavy load, it’s always on when the inverter is on, and it is loudThe cigarette lighter plug has no fuse in it (I do not know whether there is a fuse inside of the unit itself)I live off-grid for several reasons, so I always like to have plenty of power inverters around. Although I prefer to use pure sinewave inverters, these little cheap square wave inverters come in handy, and this one has pretty good performance, and even survived brief polarity reversal (there was a 25 amp fuse between the socket and the battery)There are lots of portable power sources that sell for hundreds of dollars that basically consist of a cheap universal SLA 12v battery, a charger and a power inverter, you could build one of your own item would using this item as the power inverter and maybe a couple small Odyssey motorcycle dual-use deep-cycle and starting batteries like the 12AH PC545Â

I got this to power my firestick and T-Mobile home internet in my motorhome. It was very quiet, didn’t heat up, and served my purposes well. It also looked to be assembled and finished off correctly.

I read reviews that said it would blow a fuse in the vehicle if over amps but they have fixed that issue. Even given a short circuit on the output only puts it into alarm and it returns to normal when the short is removed. It delivers full rated power and works perfectly!

Needed it for an air pump to inflate giant inter tubes for sledding. It worked great and had enough power. I’m sure I will use it for other things.

This is a great product if you want to charge anything in the car. It’s compact, easy to use. I use it to charge my computer and many other items.

Amazing
Does the job as described – enough said.Well built and solid. I use it in my truck and its a great product.
Paul Arnold –
Very sturdy
Very pleased with this and works well for electronic devices so we need power in the vehicle. Took it on a long trip and my family was able to watch movies in the car on the way to our destinations. No issues. Recommend product.

Works Great
Run a printer and computer charger off it in the truck and has worked great for 8 months now. No complaints.

Excellent product
Had older generation version of this and after continuous use it would get almost hot to the touch.This one here is quieter and it has not generated anywhere near the heat from it’s predecessors.Excellent to have for the car for any electronic powering that is needed.

Works great
Needed to be able to power a laptop in a vehicle as my job is mobile. This was recommended as a very good and cost effective option. Only been using in for a couple of days but so far, so good.
