You've got a Teltonika device that needs a direct solar or DC feed, or you want to tap a digital input/output line without guessing at the pinout. This cable does both. One end is a 4-way screw terminal so you can strip a wire and clamp it down – no crimping tool, no soldering iron. The other end is a 4-pin connector (3 mm pitch) that slots straight into your Teltonika unit. Colour-coded pins mean you wire Power+, Ground, and the two I/O lines in under two minutes and know you've got it right. RoHS compliant. 2-metre reach gets you from the battery box to the device without a dangle
