There was a problem filtering reviews right now. Please try again later.
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.
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 300Watts
It's a relatively small for the wattage provides
Doesn't seem to have a problem with picky loads like fluorescent lightbulbs, even big ones.
Includes two USB ports
And 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 loud
The 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 PC545 Odyssey PC545 Powersports Battery use a charger like the Schumacher Schumacher SC-600A SpeedCharge High Frequency Battery Charger with quick disconnect terminals, and you have yourself a portable power supply that can be recharged quickly, and be deep cycled. If you put a 20 W solar panel Ramsond® 20 Watt 20W W Solar Panel Module 12V Nominal Output RV Boat Battery Charger Charging Trickle Boat and add a cheapo 7 A charge controller Sunforce 7 Amp Charge Controller you have yourself portable emergency power for a fraction of what a completed solution would cost. That is what I will be using this unit for, since it is too noisy for just charging my phone when I am in a car, and its a good match for the above application.
Top reviews from other countries
Well built and solid. I use it in my truck and its a great product.
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.
It's compact (fits in the glove compartment), sleek and seems solid. I can't speak to the internals and reliability of all that just yet, but a few days in I can comfortably rate it a 5 star.
