GELRHONR 12V car cigarette lighter splitter extension cable with on/off switch (1 to 3 ports, 15A fuse)
Product description
What it is and why you might want one
If your car only has one 12V cigarette lighter socket, it can get annoying fast—dash cams, GPS units, phone chargers, and all the little “grab-and-go” gadgets add up. This GELRHONR 12V cigarette lighter splitter is an extension lead designed to turn one 12V outlet into up to three ways to plug in devices.
On paper, the appeal is simple: you get a 1-to-3 splitter with an integrated on/off switch, plus a 15A fuse for extra protection. The cable length options mentioned (including 1 metre) also matter in real use, because where the socket sits in your car can make the difference between a tidy setup and a lead that’s always in the way.
It’s not a mystery device or something you need to “tune” for your car. You plug it in, switch it on, and you’re using the same 12V power point for multiple accessories.
The essentials: what you get from the design
This is a Y-style (female-to-cigar-lighter) splitter extension cable. The splitter lets you connect up to three 12V devices at the same time, with a stated maximum current rating of 15A across the total setup.
A practical touch is the built-in on/off switch. It’s intended for quick connection and disconnection without having to keep pulling the plug from the socket. That may sound minor, but if you frequently remove your dash camera leads or swap between devices, it can reduce wear on the car’s lighter interface.
What the fuse protection is meant to cover
The product description specifically highlights a 15A fuse housing and protection features aimed at overcurrent, overtemperature, and short-circuit scenarios. The idea is straightforward: if something goes wrong electrically, the fuse should help protect both the car and your plugged-in electronics. That’s reassuring, but it’s still worth being sensible about what you connect.
What’s likely to work well in everyday car life
If you’re building a compact car kit—think GPS on one port, a dash or dashboard camera on another, and a USB car charger on the third—this kind of splitter is exactly the style of accessory you’d use. The description also lists examples such as a reversing camera system, a mini portable fridge, and even a mini car vacuum.
A small micro-scenario: say you park the car every evening and want the dash cam running but your phone charging should only happen when you’re driving. With an on/off switch, you can plug everything in, leave it neat, then turn power on when you’re ready to set off.
Where it fits best is when you want convenience without changing your vehicle’s existing socket.
The limitations you should keep in mind
It may not suit you if you’re planning to run power-hungry devices continuously. The maximum rating is stated as 15A total for the splitter, and the description talks about protecting against overcurrent—so you’ll want to make sure the combined draw of your connected accessories doesn’t exceed what the cable/splitter is designed for.
Another point: the cable length is described as 0.3 m in one place, while also mentioning sizes of 100 cm and 1 metre. If you’re buying for a specific routing in your car, it’s worth double-checking which length you’re actually getting on the listing.
Finally, because this is a basic 12V extension + splitter approach, it won’t magically fix poor cable routing, loose sockets, or devices that don’t behave well when powered through a splitter.
Is it a good fit for you?
It’s a good fit if you want one 12V cigarette lighter socket to power several small car accessories and you value the convenience of an on/off switch.
It makes sense if your devices are all designed for 12V operation and you’re comfortable treating the 15A fuse rating as the ceiling for the combined load.
It might not be a great match if you need to run high-power equipment for long periods, or if you’re unsure about how much power your accessories draw together.
You may want to skip it if the cable length on the listing doesn’t match how you plan to route the lead in your vehicle.
Key takeaways: what to check before buying
Before you commit, it’s worth checking: - That the devices you plan to use are suitable for a 12V cigarette lighter power supply. - Whether the combined power requirement of all devices fits within the stated maximum current (15A total). - The exact cable length you’ll receive, since the description references different lengths.
No gadget is perfect, but this one is fairly straightforward: it’s a practical splitter with a switch and fuse protection, designed to make a cramped car power situation feel a lot less restrictive.
Buying verdict
It earns its place for everyday add-ons—GPS, chargers, and typical car electronics—where you’re trying to reduce plug clutter and make swapping accessories less annoying.
You should avoid it if your plan involves high-draw equipment or you can’t reasonably account for the combined current of everything you’ll plug in.
For most UK drivers trying to organise a small 12V kit, it’s a sensible “get more from one socket” solution, as long as you respect the 15A limit and confirm the cable length.
Quick FAQ
How many devices can it power at once?
The splitter is designed for 1 to 3 ports, so you can plug in up to three 12V devices at the same time.
What does the 15A fuse do?
The description says it provides protection against overcurrent, overtemperature, and short-circuit situations, intended to help protect both the car and the connected electronics.
Does the on/off switch let you disconnect without unplugging?
Yes—the switch is intended for quick connection and disconnection, so you can turn power on and off without repeatedly pulling the plug from the socket.
What cable length should I expect?
The listing text mentions 0.3 m and also mentions lengths of 100 cm and 1 metre, so it’s worth checking the exact option shown on the page for your order.
