Mobile Power Cable with Inline Fuse Assembly
Heavy-Duty Vehicle Battery Integration for Mobile Transceivers
The Motorola HKN4191C is a commercial-grade 10-foot DC power cable designed to connect Motorola mobile two-way radios directly to a vehicle battery. Built with 12 AWG copper conductors rated for 20A, it delivers stable, high-amperage power to vehicle-mounted transceivers and includes an integrated inline fuse holder to protect radio electronics from power surges. The HKN4191C is the current factory-authorized revision, updating the previous HKN4191B and HKN4191A part numbers.
Key Features & Benefits
Integrated Inline 20A Fuse: Pre-installed automotive fuse assembly protects the radio from electrical overcurrent spikes.
12 AWG Copper Conductors: Heavy-gauge wiring minimizes resistance and maintains stable voltage over the full 10-foot run.
Ruggedized Insulation: Heavy-wall polymer jacket withstands engine bay heat, fluid exposure, and continuous vibration.
Secure 2-Pin Locking Plug: High-retention connector locks directly onto the radio power port to resist road vibration disconnections.
Replaces HKN4191A / HKN4191B: Current revision superseding all previous HKN4191 part numbers.

Frequently Asked Questions
Does this power cable come with the inline fuse included?
Yes. The HKN4191C includes an integrated inline fuse holder pre-loaded with a 20A automotive blade fuse.
Can I shorten this cable for a smaller installation?
Yes. The 10-foot cable can be trimmed by an experienced technician. If shortened, ensure the inline fuse block remains positioned as close to the positive battery terminal as possible and that all connections are properly secured.
Will this cable work with high-power 100W mobile radios?
No. The HKN4191C is rated for 20A and is optimized for mid-power transceivers in the 40–60W range. High-power mobile radios drawing higher currents require a heavier-gauge cable such as the Motorola HKN4192C.
What is the difference between the HKN4191C and the HKN4137B?
The HKN4137B is a 14 AWG, 15A cable suited for lower-power mobile radios in the 25–40W range. The HKN4191C uses heavier 12 AWG conductors rated for 20A, making it the correct choice for mid-power 40–60W transceivers. Always match the cable rating to your radio's power output.
Where should the inline fuse be positioned during installation?
The inline fuse holder should be positioned as close to the positive vehicle battery terminal as possible — ideally within 18 inches. This ensures the fuse protects the entire cable run in the event of a short circuit, preventing potential fire or electrical damage.
