ALLWEI 300W Car Power Inverter, 12V DC to 110V AC, Red
Product description
Two AC outlets plus USB-C and USB-A charging give this 300W inverter a practical role on road trips: power compatible electronics and charge phones from a vehicle’s 12V socket.
Its 27W USB-C PD and 18W USB-A ports provide dedicated options for charging phones and tablets, while the AC outlets support devices such as laptops, cameras, and game consoles.
The red unit has an aluminum-alloy housing, a temperature-controlled cooling fan, and a 33-inch cord for reaching the back seat. It’s designed for in-car charging and power, whether you’re commuting, camping, or driving long distances.
At a glance
The inverter converts 12V DC vehicle power to 110V AC and provides 300W of rated output. Two AC outlets let you connect compatible devices, and the USB-C PD port and USB-A port add charging options without using an AC outlet. The USB-C port is rated at 27W, and the USB-A port at 18W, the stated maximum total USB output is 3A.
The compact housing measures 4.7 inches long, 3.1 inches wide, and 1.8 inches high, and weighs 8.8 ounces. Its 33-inch cord gives the plug-in unit room to sit within reach of passengers in the back seat. For shoppers choosing between a USB-only car charger and an inverter, the AC outlets are the key difference: they provide a way to power compatible devices with an AC plug while traveling.
Who it’s for
This setup suits drivers who want to charge several kinds of small electronics from a vehicle, rather than relying on USB ports alone. On a road trip, for example, a passenger can charge a phone through USB while another compatible device uses an AC outlet. It can also serve campers who need in-vehicle charging for electronics such as cameras or tablets.
Customer feedback highlights road-trip and camping use, with varied reports on charging performance and fan noise. Some buyers describe the inverter as useful for laptops, while others report mixed results, experiences with noise and reliability also vary. Treat these as individual impressions, and match the connected device’s power needs to the inverter’s ratings.
Usage tips
Plug the inverter into a 12V vehicle power socket for use with devices up to 180W. For a device over 180W, use battery clips, as directed in the product information. Check the device’s power requirements before connecting it, and use the AC outlets for compatible AC-powered electronics. The USB-C and USB-A ports provide separate choices for phones and tablets.
The built-in fan adjusts its speed according to temperature. Leave the inverter positioned so its housing and fan can operate during use, and route the cord where passengers can reach it without pulling on the connection.
What to clarify
What can I connect to the AC outlets? They’re intended for compatible electronics such as laptops, cameras, game consoles, TVs, and DVD players. The inverter’s rated output is 300W, check the device’s power requirements before use.
Can I use it with a 12V car socket? Yes. The inverter takes 12V DC input from a vehicle power socket. For devices over 180W, use battery clips instead of the socket connection.
Which USB charging ports are available? It has one 27W USB-C PD port and one 18W USB-A port, with a stated maximum total USB output of 3A.

Its mix of ports makes it useful for road trips, camping, and everyday drives when compatible electronics need power from a 12V vehicle supply.
