Choosing car power gear usually starts with a simple question: are you trying to take power with you, or do you need power to dig into the car itself? The two accessories in this head-to-head point in opposite directions, so the right choice depends on the job you actually want to do.
Quick verdict
If your priority is deep cleaning seats, dashboards, wheels, and floors, the portable steam cleaner at USD 87.19 is the one to choose. If you mainly want a traveling power hub for phones, laptops, and small AC appliances, the 300W inverter at USD 169.99 fits better. The two aren't interchangeable, so the decision comes down to what you'll actually do with it.

Product notes
Portable High Pressure Car Detailing Steam Cleaner Vehicle Auto Cleaning Tool
The main reason to choose this cleaner is the combination of high-temperature steam and pressure. The 1700W unit heats water to at least 212°F and delivers 3-3.5 bar of pressure, which helps break down dust, oil, and grime on car bodies, upholstery, floors, and steps. The spray gun is shaped for a comfortable grip, and the ABS and stainless steel build is made to handle repeated use and resist corrosion. The trade-off is the cord: you'll need to work near an outlet or run an extension line. If your car power need is about cleaning surfaces rather than charging electronics, this is the practical pick.
300W Portable Car Power Inverter Charger - 3-Pack Vehicle Accessories
The case for this inverter is portability and versatility. It converts your car's 12V DC power to 110V AC, giving you four USB-C/A ports that share 24W for phones and tablets, plus dual 110V AC outlets for a small kitchen appliance or other travel essentials. It comes as a three-unit set, so you can keep one in the car, one in a travel bag, and one close at hand. The unit measures just 5.4 x 2.75 x 1.4 inches and weighs 9.17 oz, which makes it easy to stash in a glovebox or camping kit. The limitation is the output: it's best for light-duty electronics, not high-draw power tools or large appliances.
Final choice by use case
For car detailing and steam cleaning, choose the portable steam cleaner. For a portable charging hub that handles USB devices and small AC gear, choose the 300W inverter.
