2. Please use a battery clip when using inverter on device over 180W(the battery clips not included). Because most car’s 12v cigarette lighter port is with fuse 15A, then formula P=UI(180W=12V x 15A), so you won’t be able to use device which is more than 180W if connect with car‘s 12V cigarette lighter ports; unless you plug directly into car’s battery, or connect to a 12V battery.Please check the ampere of the fuse in your car.

Excellent power inverter
Works perfectly so far over a year.

Company stands behind its warranty.
I bought this because I work in my car and my laptop has a 300W charger that would keep blowing the fuse every time I tried to use other inverters in my car. This works perfectly, it does have a fan that is noticeable if there is no background noise while you are parked. While you are driving or have a radio playing you cannot notice the fan much at all. After about 2 months of use the inside area of the 110 outlet broke and separated from the housing, making that part unusable. I contacted the seller and had a response within minutes. Within the hour they let me know they would be sending me a replacement through Amazon and I received it 2 days later. It is refreshing to know that the seller stands behind their warranty and product. Now I know this is a brand that I can trust to purchase with moving forward.

Is doing exactly what I expected it to do
I bought this so I could charge my laptop in my truck as I work out of my truck. A lot works perfectly small size. I was able to mount it inconspicuously.

Died pretty quickly at less than 50% load
Edit: Updated to 4 stars from one for great customer service. The vendor reached out to me after my review and simply refunded my money. They never asked for a revision to my review, which is a big peeve for me, or even for me to return it. I ended up taking it apart and found that a wiring connector to the switch had a bad crimp and was able to fix it. I updated my review to 4 stars simply for their good customer service and because after looking inside, the unit overall seems to have a good build quality. Hopefully the connector was just a QC issue that will be resolved considering their fast response to my review. While a QC issue is annoying, it’s good to know that if a problem arises the vendor will make it right.Original review:I bought this to keep my wife’s laptop powered up on long roadtrips as the 100w built in one in our car sometimes shuts down if she tries to use it and charge a dead battery at the same time (she has a core I9 powerhouse laptop with a 150 watt PS). Plugged this unit into the 12v power port and it charged the laptop for a 3 hour drive, but then wouldn’t turn on for the trip home. The power port still works and the OEM 100W built in inverter will still power it for the most part, so I do not believe there is any problem with the car or the laptop. I’ll be returning it and looking for a more well known brand.

Very useful
This device has been very useful to me as I spend a lot of time working with my computer in vehicles. I can easily charge different devices with it and it has lasted over 6 months so far

Loved the first one bought a 2nd for our other jeep
This was perfect in our jeep during a parade and wanted to put inflatables on top of it. Light weight, doesn’t heat up, puts out the power you need.
Honest Reviews by Victor L. Goodman –
Missing too much to be YOUR inverter
May 2022 Update: product wattage rating LOWER than advertised. With car engine running to keep the car battery at max voltage and not to be a factor and NOTHING plugged into the 2 x USB-A ports), I plugged into outlet #1 my rechargeable Braunn electric shaver and into outlet #2 my ASUS laptop [combined wattage under 300] and the devices would keep cutting out. Only one device would charge at a time. First a laptop would start charging and then after a couple seconds it would beep of being unplugged and then my cell phone again charging. I don’t understand why both devices could not charge simultaneously when both devices combined was under the “rated” 300 watts.My advice to those looking to purchase and inverter: WHATEVER YOUR TOTAL WATTAGE NEEDS ARE, DOUBLE IT IF YOU CAN AFFORD TO DO SO. IF YOU’RE WORKING ON A BUDGET INCREASE BY 50%. So if you need 200 watts purchase at least 300watts (50% extra to buffer you from manufacturer’s over exaggerated claims)Original review:This model and all brands putting their logo on this model type is something you should PASS ON.PUTTING aside the poor build quality and subpar components that are hidden within this fancy aluminum case, PUTTING aside the short life expectancy of such a product (dont expect this to last a single year with daily use), here are the FLAWS why all these models (150-300 watt) products in this product line should be SKIPPED OVER:1) Wattage: I doubt many of you will test your product to ensure it actually produces 300w but give it a try (with a voltmeter to verify). My 300w unit struggled to keep a 185w gaming laptop going.2) outlet placement – this is a biggie. All these models on this product line put both outlets so close together that you really only have ONE OUTLET. Modern phone chargers and devices have a fat plug so 2 plugs can’t fit side by side. If they had just SPACED out the 2 outlets by 1 more inch or even ROTATED the second plug 90 degrees so they won’t hit each other – that right there shows a lack of design and if such a simple thing was overlooked, makes you wonder what critical components inside were overlooked as well. SUCH AS the power switch being IN THE BACK. And the switch only controls the 2 outlets. The switch doesn’t control the USB ports.There are no mounting brackets or way to semi permanent connect inverter. You’ll have to DIY your own tape/ Velcro to the dashboard if you don’t want it sliding around while driving…Lastly because this is a budget priced model I won’t hold the following things against it. But I will mention their absence:- Only 1 cooling fan. This unit gets HOT when maxing out. And at only 300 peak watts it WILL max out often.- Not a pure sine wave. An issue for using this with electronics. Also because its not a pure sine wave it DRAWS MORE POWER from your car battery for the same output.- All USB ports SHARE the amperage output so if you have your phone high speed charging and plug in a second phone then the first phone charging speed will HALVE.-USB ports are NOT on seperate circuits. If one device somehow shorts out and fries the port it will feedback into tbe other USB connected device- NO LCD screen. No indicator lights to alert you when maxing out wattage or when a fuse needs replacing.

This arrived while we were away and when we got back it was too late to return.This inverter is only suitable for America and not the UK or Europe.We were confused why an American item was being sold on a UK Amazon site.Our fault I suppose but we did not find any information which stated it was not suitable for the UK
