When your car's existing power point is already occupied, you have two very different ways to add another one: a compact socket that plugs into the lighter position, or a power inverter that converts the vehicle's power for larger electronics. They solve separate problems, and the right pick depends on what you need to run. Here's how the 12V Cigarette Lighter Socket Power Outlet and the 300W Portable Car Power Inverter compare for everyday car power.
Quick verdict
If you want a simple second outlet for one 12V accessory, the $5.69 12V Cigarette Lighter Socket Power Outlet keeps things easy and compact. If you need standard wall-plug power and multiple USB ports for road trips, the $169.99 300W Portable Car Power Inverter Charger is the broader solution.

|---|---|---|
| Listed price | $5.69 | $169.99 |
| Best for | Adding a simple 12V outlet for one compatible device | Running multiple devices from 110V AC and USB ports |
| Power format | 12V-24V socket | DC 12V to 110V AC conversion |
| Charging ports | One 12V socket receptacle | 4 USB-C/A 24W charging ports and dual 110V AC outlets |

Where each product wins
The 12V Cigarette Lighter Socket Power Outlet is the no-fuss answer when you want a second outlet that takes up almost no room and doesn't change how you power your existing devices.
The 300W Portable Car Power Inverter Charger is the stronger match when your gear expects wall-outlet power or you need to charge several things at once rather than one at a time.
Product notes
12V Cigarette Lighter Socket Power Outlet
If your goal is simply to add one more 12V outlet where there isn't one, this compact socket keeps things basic. The protective waterproof dust cover helps shield the connection when it's not in use, and the small 5.8cm height makes it easy to place in cars, motorcycles, boats, ATVs, tractors, and other 12V-24V vehicles. That wide vehicle compatibility is the main reason to pick it up. The trade-off is that it's a 12V outlet only: it provides the same kind of power as a standard lighter socket, so it won't give you the standard wall-outlet power the inverter provides. If all you need is a dedicated connection for a GPS or a compatible device charger, that's exactly the job this tiny receptacle is built for.
300W Portable Car Power Inverter Charger
When the situation calls for more than 12V, this inverter brings the versatility. It includes four USB-C/A 24W charging ports plus dual 110V AC outlets, so multiple devices can stay powered at once. It weighs only 9.17 oz and measures 5.4×2.75×1.4 inches, which keeps it manageable for a car or camping bag. The main limitation is that it still depends on your vehicle's 12V DC source, converting it to 110V AC; in other words, it's a power converter, not a standalone battery. If your need is running a smart kitchen appliance, a GPS unit, or several smaller electronics while away from a wall outlet, this 3-pack of vehicle accessories gives you the headroom a simple socket can't.
Final choice by use case
If you only need a dedicated outlet for a GPS or one compatible device charger, the 12V Cigarette Lighter Socket Power Outlet does the job without asking for much space. If you're planning a camping trip, tailgate, or long drive with GPS devices, smart kitchen appliances, and multiple USB gadgets, the 300W Portable Car Power Inverter Charger is the one that keeps everything powered.
