Your car's factory power outlet is always in the wrong spot when you need it. When you're shopping for car power, you're usually choosing between two very different fixes: multiply one socket into several power points, or add a standalone 12V point where you want it. The 7-in-1 4-way splitter and the 12V socket outlet represent those two approaches. Let's see which one actually solves your problem.
Quick Verdict
If you need to charge several devices while you drive, the 7-in-1 4-way splitter is the better buy. It turns one occupied lighter socket into a small power station. If you only need an additional 12V point for a compatible device, the 12V socket outlet is less expensive.
Comparison

|---|---|---|
| Price | USD 8.99 | USD 5.69 |
| Input range | DC 12V~24V | 12V |
| Main function | Adds extra sockets and USB fast-charging ports | Adds a single 12V outlet |
| Safety | Over-current, over-voltage, and short-circuit protection | Waterproof dust cover |
| Best for | Powering several gadgets at once | A spare power point |
Where Each Product Wins
The splitter wins when your priority is capacity. You keep one lighter socket occupied while still having an extra socket and charging ports for your gear, so you're not swapping accessories between stops.
The socket outlet wins when your priority is a clean, dedicated outlet. Its compact dimensions make it a better fit for a setup where you want the outlet sheltered from the elements.
Product Notes
7-in-1 4-Way Splitter
The splitter is the go-to when you want one occupied lighter socket to become a small power station. It adds multiple sockets plus USB and Type-C ports, with Quick Charge 3.0 and PD 3.1A support, so up to three devices can charge at the same time. It runs on DC 12V~24V, offers a total output of 120W (max), and includes a 10A fuse plus over-current, over-voltage, and short-circuit protection. The physical trade-off is the 60cm/23.6in cable: the adapter body sits away from the socket, so it takes up visible space rather than hiding in the panel. If you want the power point to hide away out of sight, this won't satisfy you; if you need a mobile hub for trips, it fits.
12V Socket Outlet
The socket outlet takes the opposite, install-it approach. It is a compact 12V receptacle made for cars, motorcycles, boats, ATVs, and tractors, and the waterproof dust cover keeps the socket protected when it's not in use. At 3.7 x 3.7 x 5.8cm and just 30g, it stays out of the way in tight spaces, and the simple installation means you don't need a large mounting hole. The trade-off is that it provides one protected point for a lighter-style accessory, so the role is focused. It simply gives you a dedicated, sheltered outlet in the spot you choose. If your goal is an outlet that lives where you put it, this is the one.
Final Choice by Use Case
For long road trips or regular multi-device use, choose the 7-in-1 4-way splitter at $8.99. For installing a spare, protected outlet in a car, boat, or ATV, choose the 12V socket outlet at $5.69. If you only need one more place to plug a 12V device and want to spend less, the socket outlet does that job with a simpler setup.
