VIOFO HK3-C Hardwire Kit – USB-C 2.5A for 1-3 Channel Dash Cams

The Hardwire Kit With Headroom for Three Channels. VIOFO HK3-C delivers 2.5A over USB-C

A three-channel setup draws noticeably more than a single front camera, and an underfed kit shows up as random reboots in Parking Mode that you will spend a weekend chasing. The HK3-C is rated at 5V 2.5A precisely so a fully loaded A139 or A229 Pro stays stable while parked, and it holds four voltage cut-off levels to keep your starter battery out of trouble.

Trusted AU store: We're an authorised AU reseller, shipping from Melbourne within 24 hours^*. You get a 12-month warranty on this accessory, local technical support, and our 30-Day No-Worries returns.

Who This Isn't For: This is USB-C, so the older Mini-USB A119 V3 and A129 family need the Mini HK3. If you run an A329S and want Hybrid Parking Mode, that specifically requires the HK6. For a VS1, use the HK5.

DCG Score & Highlights

What We Love

• 2.5A output, which is the headroom a 3-channel install actually needs
• Covers a wide slice of the current VIOFO range in one part number
• Four cut-off steps across both 12V and 24V systems
• Rated from −30 °C to +60 °C, so a summer dashboard is well within spec
• Full 4 m run to reach the fuse box from the windscreen

What Could Be Better

• Fuse taps are not included, so add the correct style for your fuse box.
• Voltage cut-off only, with no parking timer. If you want time-based shutdown, the OP100 has it.
• USB-C only, and VIOFO's older Mini-USB cameras are not compatible.

Why Power Headroom Matters on Multi-Channel Setups

Adding a rear and cabin camera roughly doubles what your dash cam pulls, and Parking Mode is where an underpowered kit fails first, because the camera is running on a battery that is already sagging. Choosing a kit rated above your actual draw is the difference between reliable parked footage and a camera that reboots every time the voltage dips.

Top Benefits

• Stable on three channels: 2.5A output keeps a fully loaded A139 or A229 Pro running without brownouts.
• Battery protection you set: Four cut-off levels let you be cautious with an older battery.
• Automatic mode switching: ACC sensing puts the camera into Parking Mode as soon as you shut the car down.
• Wide model coverage: Fits A139 and A139 Pro, A229 Pro and Plus, A329, A119 Mini 2 and WM1.
• Built for the climate: Rated to +60 °C for Australian summers.
