Power Distribution

The Cable Matters TR-49P expands a single vehicle cigarette lighter socket into three additional sockets and seven USB ports. It supports simultaneous charging for up to ten devices with a combined output of 148W. The adapter is designed for 12V and 24V electrical systems in cars, trucks, SUVs and RVs.

Thermal and Electrical Behaviour

An intelligent IC chip manages current allocation across all ports to maintain stable charging and prevent overheating or overcharging during high-load use. The 45W PD3.0 USB-C port delivers fast charging for compatible laptops, tablets and phones without excessive heat buildup. Independent switches allow unused sockets to be turned off, reducing parasitic draw.

Build and Connectivity

The black housing measures 3.9878 by 12.7 by 21.5138 centimetres and weighs 0.259 kilograms. White and blue LED indicators illuminate the ports for easy location in low-light conditions. The compact form factor fits tight console spaces while the three cigarette lighter sockets accept standard 12V accessories such as dash cams or tyre inflators. Buyers needing more than three high-power accessory sockets or a hard-wired installation will need a different solution.

Questions about this item

How do I install the TR-49P splitter and what step do people often miss?

Plug the single cigarette lighter plug into your vehicle's 12V or 24V socket until it seats firmly; the step many miss is pressing each of the three socket power buttons to ON before expecting attached devices to charge.

What maintenance or replacement will the TR-49P need over time?

No scheduled maintenance is required; if the internal fuse blows from a sustained overload, replace it with an identical automotive blade fuse of the same amperage rating.

What limit appears first when I run the TR-49P at full load for a long period?

The 148 W total output ceiling is reached first; drawing more than that across the three cigarette lighter sockets and seven USB ports will trip the overload protection.
