Every driver eventually runs into the same car power problem: the car's one cigarette lighter socket is already occupied, and you need to plug in a dash cam, charge a phone, and maybe run a portable fridge. You could install a simple replacement outlet, or you could expand that single socket into a multi-device hub. That's the decision between these two products: one is a bare 12V socket you wire in; the other is a plug-in splitter that gives you outlets and USB ports.
Quick verdict
If you want the least expensive way to add a dedicated 12V outlet in a car, boat, or ATV, the 12V Cigarette Lighter Socket Power Outlet Receptacle Plug or Car Marine ATV at $5.69 is the straightforward pick. If you need to power several devices at once and want USB charging plus circuit protection, the Car Cigarette Lighter 12V-24V 4 Way Socket Splitter USB PD Charger Power Adapter at $8.59 is the better fit.
Comparison table
| Product | Price | Key specs | Price bar |
|---|---|---|---|

| Single 12V Socket | $5.69 | 1 socket, dust cover, compact |
Where each product wins
The 4-Way Socket Splitter wins for multi-device power. It expands one socket into four 12V outlets and three USB ports, and it accepts both 12V and 24V systems. The built-in protection suite covers over-voltage, low voltage, overheating, and short circuits, plus a 10A fuse.
The Single 12V Socket wins for price and simplicity. It's the lower-priced option, takes up very little space, and includes a waterproof dust cover to protect the connector when it's not in use.
Product notes
Car Cigarette Lighter 12V-24V 4 Way Socket Splitter USB PD Charger Power Adapter
This 7-in-1 hub turns one car socket into four cigarette lighter outlets and three USB charging ports, with a total output of 120W. The USB ports support fast charging, and the built-in protections cover over-voltage, low voltage, overheating, and short circuits. The 60cm/23.6in cable lets you position it away from the dash, and the 10A fuse adds an extra layer of safety. Compared with the single socket, it costs more, but the added outlets and charging ports make it the more capable choice for drivers who carry multiple devices. One limitation: it plugs into your existing socket, so you'll need to find a place for the cable and it won't permanently mount into the dash.
12V Cigarette Lighter Socket Power Outlet Receptacle Plug or Car Marine ATV
The lower-priced of the two, this socket gives you a functional 12V outlet for cars, motorcycles, boats, ATVs, and tractors. Its compact body measures about 3.7cm square and 5.8cm tall, and the waterproof dust cover keeps moisture and dirt out when the outlet isn't in use. The design is meant for simple installation without requiring a large mounting hole, so it can be placed in tight spots. The trade-off: you get exactly one outlet, no USB ports, and no cable, so it's best for a single accessory like a phone charger or GPS unit. It's the sensible pick when your car power need is straightforward and you want a permanent, simple socket.
Final choice by use case
Choose the 4-Way Socket Splitter if you regularly run a dash cam, tire inflator, and phone charger at the same time, or if you want USB PD charging without wiring in a new outlet. Choose the Single 12V Socket if you just need one extra outlet in a secondary vehicle or want the most straightforward, lowest-price car power solution with a protective cover.
