That being said, for the price, these units have done well for me. It will charge my laptop at 140w, power a fan, and the usb ports work well, but slowly. Like less then 5a.
The ac ports work for my needs by fast charging all my rechargeable devices.
I do have a dedicated 20a hard wired fuse though. And, the fan is a bit loud when it gets running.
Also, don't leave them plugged in when shutting off your engine. The parasitic draw on these things are terrible.
