The majority of cars will only have 1 cigarette lighter socket at the front of the car. This can be a problem when multiple electric devices require electrical charge.

The best cigarette lighter splitter is the BESTEK 3-Socket 200W 12V/24V DC that has 3 sockets and 4 USB ports that are protected by a built-in 10A fuse and protective circuits to prevent overheating or overcharging.

Cigarette Lighter Splitter Buying Guide

As technology has improved and there are more electronic device available, the need to charge whilst driving has increased. For example, due to the budget dash cam craze, a large amount of people charge whilst driving, leaving no other cigarette socket available for other devices.

Having to switch between the 12V/24V sockets all the time will cause additional wear and tear. Highly rated cigarette lighter splitters that contain additional sockets and USB have come along way and have become much safer. Below are some considerations you should take before going for a certain cigarette lighter adapter.

Additional Sockets or USB Ports

Choosing a certain style of adapter can be tricky because there are so many different types. For example, some may just have additional sockets, some may have both sockets and USB ports whereas other will be complete with just USB ports.

You should ask yourself what charging ports you require and how many in total. Of course, more the better but if you are only using sockets or just USBs, there is no need for the additions if you will not use them.

For example, if you have headrest DVD players that use sockets, its vital that the adapter can handle the current draw. On the flipside, the majority of smartphones use a USB port for fast charging. If the cigarette lighter splitter only has sockets, you will need to purchase a USB to 12V/24v adapter in order to charge your phone.


Sadly, there are so many cheap knock off splitters available that have poor wiring and some without fuses. This is simply asking for trouble and won’t last a few months. It is always advised to go with a more expensive cigarette lighter adapter that includes a range of safety features.

Look out for CE, ROHS, FCC and ISO9001 certification as well as Surge protection, USB intelligent identification, Overload protection, Over voltage protection, Over current protection and Short circuit protection.

If you are concerned with how the splitter is working, you will be able to test with a multimeter designed for cars that provides feedback of the voltage passing through. If it is dropping below 10.5 or operating at high voltage, avoid using it and contact the manufacturer.


There are two distinctive designs to choose from that include fixed into the cigarette lighter socket or ones that use a power cord. Fixed cigarette lighter splitters are more compact, flow with the design of the car but have less sockets or USB ports. Some fixed units will have rotation on the connector for movement in order to fit properly without being in the way.

Units that have a power cord can extend to reach the back seat passengers which is a huge bonus. However, they will need to be secured down or kept in a area that wont allow it to be thrown around whilst driving. They are often much larger and provide more additional sockets or USB’s.


All of the highly rated cigarette lighter splitters above are safe units to use with a range of different sockets and USB’s. Before purchasing, ensure you will have the correct number of 12V/24V sockets and USB ports. We strongly recommend that you avoid the cheap models as you may damage your own charger or blow the cigarette lighter fuse itself.
