VIOFO Mini HK3 Hardwire Kit – Mini-USB for A119 V3 & A129 Series

The Hardwire Kit for VIOFO's Mini-USB Cameras. Mini HK3 fits the A119 V3 and the A129 family

If you bought your VIOFO a few years back, it almost certainly takes Mini-USB rather than USB-C, and none of the newer kits will plug in. The Mini HK3 is the one that fits. It taps constant power from the fuse box so Parking Mode actually runs when you walk away, with four selectable cut-off levels keeping your starter battery safe.

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 Mini-USB only. Every current VIOFO camera uses USB-C, so if yours is recent you want the HK4 or the HK3-C. Check the port on your camera rather than the model name, because VIOFO reused numbering across both connector types.

DCG Score & Highlights

What We Love

• Fits the A119 V3 and the full A129 line including Duo, Duo IR, Pro Duo, Plus Duo and Plus Duo IR
• ACC detection switches the camera into Parking Mode automatically at ignition off
• Four cut-off levels, with 24V equivalents for light trucks
• 4 m run, long enough to reach the fuse box in most cars
• Keeps a still-good older camera useful rather than forcing an upgrade

What Could Be Better

• Add-a-fuse taps are sold separately, so order the right style alongside it.
• Mini-USB connectors are less robust than USB-C and do not like repeated unplugging.
• Voltage cut-off only, with no parking timer.

Why an Older Camera Still Deserves a Hardwire Kit

An A129 that records well is not improved by replacing it, but it is severely limited by the cigarette socket, which dies with the ignition and takes parked recording with it. Hardwiring costs a fraction of a new camera and unlocks the one capability the socket can never provide.

Top Benefits

• Parked recording unlocked: Constant power keeps motion and impact detection alive while you are away.
• Battery protection you choose: Four cut-off levels to suit your battery's age and condition.
• Hands-off switching: ACC sensing moves the camera between driving and parked modes on its own.
• Frees the 12V socket: The cigarette lighter goes back to charging your phone.
• Cars and light trucks: 12–24 V input covers both.
