ALLWEI 300W Car Power Inverter DC 12V to 110V AC for Vehicles Converter USB-C PD65W/18W Fast Charging Ports Car Charger Adapter (Black)

Used this for my laptop and for my cpap while in the car and away on business trips. Works great. No issues!

So far so good! It’s a lot lighter than I thought it would be. The fan is really quiet contrary to what other people have commented… it blew up a plug in car air mattress no problem! Excited to use it some more.

This ALLWEI inverter is a road trip essential! The USB-C PD65W port charges my laptop fast, and the dual AC outlets handle small gadgets with ease. Compact, quiet, and reliable—just remember to use battery clips for devices over 180W. Great value for staying powered on the go.​

So far so good. Compact size, solid construction.Would be better if there was a mounting bracket or screw slot. But it’s light enough some double stick tape will do.

Works great.

Fast and efficientPower cord could be a couple inches longer tho but works great

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.

Works great
