Similarly, Tina Garbarino claimed it to be the best power inverter she had used after going through three others. She also pointed out that it’s a product you can’t cheap out on, indicating its quality.
The compact size and charging capabilities of the product also seem to have won over many users. Richard Kearney commended the product for its efficiency, allowing him to use Bluetooth in his 2003 Tacoma. Another user, Michael, applauded the product’s portability, stating that it worked well with his small laptop in his car. Users also appreciated the inverter’s low noise level while in use.

Estrick, the product has remained sturdy, durable, and reliable even after several years of use. For Krystal, it has become a constant companion during car trips and camping, used frequently to charge a computer and phone.
Despite the numerous positive reviews, the product has also received its share of criticism. Several customers expressed disappointment over the product’s reliability and functionality.

Derek Ramp, for instance, lamented how the product burned through three fuses in his truck after just two uses. Another customer, Just me, was upset that the product broke the auxiliary power outlet in their new car after one use.
Lastly, some customers questioned the product’s power capabilities. Charles Stark noted that the product doesn’t do anything a cigarette adapter wouldn’t do and that it doesn’t power much. Mike also reported that the inverters do not work properly, turning on and off every second, making it impossible to charge. He further criticized the company’s customer service for not responding to messages for help or warranty.
What do the stars speak of?
Opinions about this product were divided in such a proportion among the buyers.
I was really worried because I have an air mattress that has a built in pump, i didn’t know if that was going to be an issue. But damn! This thing really pulled through and did an amazing job. Totally need this if you’re inflating beds/floats on a camping trip. Totally awesome.
Goes in fault mode without anything plugged in! 🤬

Worked as described
Took this camping where we needed a 120V outlet for our inflatable mattress and to charge our phones. It worked as described. The power cord is conveniently long; allowing us to keep the cord outside of the car while keeping it plugged in and the air mattress inflated.
Amazon Customer –
All good
It’s exactly what I ordered and it showed up in good time and good shape.
Daniel G. Reid –
Failed in less than 30 days
Initially it worked fine, but less than 30 days later, it completely stopped working. Beware of this one.
Novercalis –
It works
Got it for camping so I could blow up my air mattress and it just works!
nknmanzm –
Works great and is nicely sized.
This works great. It is smaller than I thought it would be. Fits nicely under my radio in the SUV. It has a light that shows you when it’s on. It has an easy off and on switch. It’s great for camping. The cable length is great but not long enough to leave a car. Make sure there’s room somewhere near-ish to where it plugs in. I appreciate the combination of ports offered.

This Product is a Game Changer if You’re a Camper
Anything you need power for that wouldn’t charge direct from the car can be done with this.
Adan –
Don’t even bother
Would give it a zero, the moment I connected something to the inverter immediately blew a fuse. Tried it twice to make sure it was the inverter and it definitely was. Thankfully I have a bunch of spare fuses if not it would’ve been even more annoying.

Great
Great bang for the buck. Great addition to an older vehicle that doesn’t have a build in inverter and outlets. Very convenient!
Bau Nguyen –
Does it job
This ensures I can keep my cell phones charged though not everything at once of course. I wish I had known about this kind of a product much earlier!
julius –
Not durable
I bought this product in February and barely used it. I used it today for the first time for my laptop. Boom! It short circuited and no longer working. Too bad I can’t return the product because it is pass 30 days since I bought it. Not a durable product.
Rhea Samons –
Great products!
It’s super easy to use, not too bulky and I don’t have any loud noise coming from it. It doesn’t over heat and it’s of great quality. It charges my devices with optimal speed and it has performed really great.
Gus –
Bad
I plugged this devised into my Lexus LS and the clock on my car started going fast which was odd. I looked into this and one of the conclusions that external battery charges like this could affect the clock. Not sure if anyone else has experienced this.
Alexa –
Quality is good , working well, recommended
I brought a charger from home depot for my laptop, it was little expensive but didn’t work at all. Now on a friends recommendation i tried this one and it works amazingly well

Perfect Charger
This is the perfect charger for my truck I have a Dodge Ram that did not have any plugins and when you need a plug-in you need a plug-in, so this works great, I don’t leave home without it

Works well but noisy
It works well but emits a high pitch squealing noise
None of your business –
Not what i expected!!!
This device is very noisy, I thought it was gonna catch on fire or something. Also, it does not consistently charge my 200w laptop, the charging cuts on and off. although, it’s great for charging, ear buds, my cell phone and my Nintendo switch light (portable gaming console).
Ralph Guest –
Works well
Plugged it in and away she went
Carly –
Good investment
Works well. Plug our electric knife in to clean fish. Has enough power to keep the knife running. It is a good investment for a small inverter. L
Mark A. Phillips –
This inverter has bailed me out SEVERAL times!
I have used this on SEVERAL occasions where I have needed to charge a camera battery while away from an outlet. You can plug in you charger and still use the two USB ports to charge your phone, hook up your dash cam or whatever. It handles to load just fine.

inverter

Sandy Farrell –
Quality Product!
I am really enjoying this little box! I can plug it into my car and then I can plug my Alexa echo dot into this inverter and take Alexa along on my car trips. This ensures I can keep my cell phones charged though not everything at once of course. I wish I had known about this kind of a product much earlier!

So far so good –
Bought this to replace an old underpowered inverter. Solid, quiet and compact.

Works
That’s it. It does what it says it does.
Gretchen P. –
Works Great!
I must’ve been living under a rock because I had no idea that these were a thing. I work remotely and in the field as a nurse case manager. I see multiple patients a day and I do all of my charting electronically while with and in between patients. I try to have a full battery when I start my day, but my laptop battery does not last past noon most days. It is so much harder than it should be to find cafe’s or diner’s that has outlets readily available to charge my laptop & chart while having lunch. I do not always have access to outlets when doing home visits either. Enter my new best friend – this product! I ordered the double outlet/double usb port model about a week ago & have been using it daily. I love it! It works well, it’s sturdy, and made with what feels like quality materials. Great price point also. I used to have to go home and chart for 2 hours after I was off the clock. Not anymore though! I can take my breaks in my car and chart. This inverter has been a life and time saver!
Ryan Dylan Beat –
Worked great and lasted just over 2 years.
Looks like I bought this February of 2022, it’s now early May 2024 as I write this review. I was looking for a replacement because it finally failed on me. It worked great, I even charge drill batteries off of it. I got some Velcro stickers so I could mount it on the side of my dash and that worked great. Very nice for $25, I might just buy this one again.

Great little inverter
Works great. Used to power laptop for passenger while traveling.
Jerry Lee Ingraham –
Instantly shorted out
I plugged it in for the first time a little over a month after purchase and as soon as I plugged in my battery to my tools it shorted out. Passed the return window, guess I’m out the money.
Harry H. –
12volt to 120v
Works perfect in my car or truck for my CD player.
br549 –
VERY noisy
I should have spent a little more on a better inverter, I’m using this one in a brand new Peterbilt semi truck and the buzzing through the speakers is so bad it’s basically unlistenable. I’ve checked the things that are plugged into it one at a time and nothing changes even if it’s empty, the buzzing starts as soon as it’s powered on
Taylor –
Broke rather quickly
Outlet broke after only a few months. For sure it should last more than one roadtrip.
Kadeem –
Will kill your car battery

Cal –
Perfect for tent Camping
I camp in a lot of areas that do not have any electrical hook ups. I only need a 120v outlet temporarily for use with an air pad pump or some other camping equipment. The key here is “temporarily” needing power for a short time. This works as advertised. Perfect for people who need a temp 120v power source like those who car or disperse camp. Very well built and sturdy.
Justin –
Stopped Working after 4-5 uses
This device stopped working after 4-5 uses. Very disappointing as out of return period as well. Seller is not responding.
Eric –
It Broke My Car
I plugged this power inverter into my brand new Toyota Camry for a road trip. I plugged in a OEM iPhone charger into the power inverter, not even a second later the car cigarette lighter stopped working. I tried a different item to plug into the cigarette lighter and it didn’t work either. After 10 minutes of troubleshooting I gave up and noticed that none of my USB’s work either in the rest of the car.
