Learn what the Carrera Additional Supply 10m cable includes, when you need it, and how to decide if it's the right track expansion piece for your setup.
Quick Answer
The Additional Supply 10m is a 10-meter power cable that extends power from your connection point to keep slot cars running at full speed on longer tracks. It's the right choice when you notice slowdowns after a certain distance.
Why Longer Tracks Need Extra Power
On longer Carrera tracks, the power from the main connection point can weaken as it travels farther, causing slot cars to slow down. The Additional Supply 10m solves this by delivering a fresh power feed to a section that's far from the source.
This cable is compatible with DIGITAL 124, DIGITAL 132, and EVOLUTION systems, making it a versatile addition to most Carrera setups. It connects to your existing power supply and runs to the point where power drops off.
What's in the Box
The product includes a 10-meter power cable designed for increased power requirements. It does not include a separate power supply unit—it's a cable that works with your existing power source.
If you're expecting a full power station, note that this is just the extension cable. You'll need to already own a compatible power supply to use it.
Decision Rules for Buying the Additional Supply 10m
- Track length: If your track is longer than about 10 meters from the connection point and cars slow down, this cable is the solution.
- Compatibility: Only buy if you have a DIGITAL 124, DIGITAL 132, or EVOLUTION system—this cable won't work with other brands. Check your system type before ordering.
- Power source: You need an existing power supply; this is just the cable, not a power unit.
- Budget: At $20.99 (compared to $29.99), it's a cost-effective fix compared to buying a second power supply. Compare with the cost of a new power supply to confirm savings.
