This is a good a fairly priced 300W unit.
I like that it is plastic casing, which lends itself better for boating and camping use. No sharp edges and doesn't scratch or mark anything. It is very light and convenient for my use. I like that the cord is built in, as I would never connect this directly to a battery in my use.
The voltage is reasonably close to 110VAC, and the unit provides adequate power without getting hot. The biggest load I have put on it is an air mattress pump, which is rated for 165W. The unit powers it perfectly and does not get hot at all even after 5 minutes of continuous use. There is a built in fan that runs all the time when the unit is switch on. It is quiet, but may annoy some in a very quiet environment. It is not a con for my use.
The USB ports work, however, I prefer to use the OEM charging cubes for my electronics. The USB ports will work in a pinch, and means you got to pack one less thing.
I would buy this again.

Need Battery Clips and Failed Out of the Box
Very disappointing. Write up for BESTEK 300W Power Inverter DC 12V to 110V AC Car Adapter with 4.8A Dual USB Car Charger makes no mention of needing battery clips for devices over 150W as recommended in the user notes (attached). Battery clips are available separately and as part of a package, but needing battery clips was an unwelcome surprise. Green light came on when plugged into cigarette lighter but changed to red (shut down) as soon as I turned on small wattage (2.5W grinder and 5.5W hand vacuum). When connected directly to the battery with battery clips, 200W grinder worked, but again the same low wattage devices caused the inverter to shut down. Received *no* response from BESTEK gmail address for service provided by 1/2 page user guide.Minor update - Have since learned that *any* device of 150 W or more should only be run from battery connections, not cigarette lighter adapter. Since this inverter is rated at 300W, probably should only be sold with battery clips. Also, some devices pure sine wave inverters; this is a modified sine wave inverter.

Decent 12v/112v (not 120v) Huge upcharge to get 1 USB C & 1 USB A instead of 2 A's. Seriously?!
