EOL announced
Teltonika has announced end of life for the Teltonika RUTX08. Orders are accepted until 3 February 2027, production runs until 3 August 2027 and support continues until 3 August 2032. Teltonika names the Teltonika RUTM08 as the replacement. According to Teltonika's wiki it has a 4-pin 9 to 50 V socket, so our cables fit it as well.
About the Teltonika RUTX08
The RUTX08 is the odd one out in the RUTX family: it has no mobile modem and no Wi-Fi. It is a wired industrial router with four Gigabit Ethernet ports, a USB port and RutOS, used for VPN, firewalling and routing between networks.
It typically sits between a machine network and the corporate network, or terminates a VPN at a remote site with a fixed line.

How much power the RUTX08 draws
Teltonika's power table puts the Teltonika RUTX08 at 1.1 W idle and 2.5 W flat out at 12 V. In current that is about 204 mA, against the 1500 mA our supply can give. On a 24 V supply the peak is about 2.6 W.
Which cable should I pick?
- Wall socket. A replacement for the original adapter, with 15.6 W of spare capacity.
- Vehicle. A quick vehicle install with a fused plug and LED.
- Cabinet, battery or solar. Bare ends for 12, 24 or 48 V DC, with the I/O wires included. Add a 2 A slow-blow fuse near the source.
Install tips
- Because the RUTX08 is often the gateway for a whole site, power it from a supply that also feeds the switch and firewall, ideally behind a small UPS.
- The Teltonika RUTX08 is rated to 50 V, which gives good margin on 24 V vehicles. A clean supply is still the best protection against spikes.
- Fit a fuse near the battery when you use the screw terminal cable on 12 V. Our FAQ suggests a 2 A slow-blow fuse.
Teltonika RUTX08 power FAQ
?Can I run the Teltonika RUTX08 on 12 V or 24 V?
Yes. The Teltonika RUTX08 accepts 9 to 50 V DC, which covers 12 V, 24 V and most 48 V DC installations.
?I lost the adapter for my Teltonika RUTX08. What do I need?
Any DC supply within 9 to 50 V DC on a Teltonika-style 4-pin plug will work. Our 230 V supply gives 12 V at 1.5 A, which suits the Teltonika RUTX08.
?Teltonika RUTX08 has no modem. Does it still need much power?
No, very little. Teltonika measured about 2.5 W at full load on 12 V, the lowest of the whole RUTX range.
?Does the screw terminal cable give access to the Teltonika RUTX08's I/O?
Yes. Only the screw terminal cable connects them. Green goes to the input and white to the output. The car cable and the 230 V supply only use the power pins.
?How much headroom does the Teltonika RUTX08 leave on an 18 W supply?
Plenty. At 2.5 W peak, the Teltonika RUTX08 uses 14% of 18 W.
?Does Smart Power Cable sell Teltonika routers?
Not the router, no. We are an independent maker of power cables. The Teltonika RUTX08 is a Teltonika product sold through their own channels.
