Rexing Smart Hardwire Kit Mini-USB Port for Supercapacitor Dash Cams

In this review the Rexing Smart Hardwire Kit is evaluated as a dedicated power accessory for owners of Rexing supercapacitor dash cams who want reliable parking mode monitoring. The kit's single biggest selling point is that it enables advanced parking features - including a G sensor wake and energy saving sleep mode - by converting vehicle DC12V-24V to a regulated 5V output through a mini-USB port. It is aimed specifically at users of compatible Rexing supercapacitor models who want continuous low-voltage protected power without relying on the camera's battery.

Key Features

• Compatibility: Made to work with all Rexing supercapacitor models such as V1-4K, V1P, V3, V2 Pro, V5 and S1 Series so owners of those models can add hardwired parking monitoring.
• Wide vehicle voltage input: The kit accepts DC12V-24V input allowing use in most cars and light trucks with standard electrical systems.
• Regulated output: Provides a 5V, 1.5A mini-USB output to power the dash cam without drawing on the vehicle battery beyond set limits.
• Low voltage protection: Includes an 11.4V cutoff to help prevent excessive battery drain while still permitting parking surveillance features.
• Long cable: The 13ft cable gives ample reach from the fuse box to the dash cam mounting area for tidy installation in most vehicles.
• Parking mode functions: Supports Gravity sensor triggered wake, sleep mode energy saving, and time lapse recording to extend surveillance with smaller SD cards.

Who It's For

The kit is best for owners of compatible Rexing supercapacitor dash cams who want a hardwired solution for advanced parking mode and are comfortable working with vehicle fuse boxes or having a professional install the kit. It is suited to drivers who prioritize impact-triggered recording and longer parked surveillance without relying on a battery model dash cam.

It is not for owners of Rexing battery models such as V1 Basic, M1, M1 Pro, M2, V2, or V360 because those models are explicitly incompatible. Also, buyers who need a different fuse style or an out-of-the-box plug-and-play adapter may find the included mini fuse connector limiting unless they provide their own adapter.

Pros & Cons

Pros

• Enables advanced parking mode features including G sensor wake and sleep mode for energy saving.
• Wide 12V-24V input range and 13ft cable make it flexible for most vehicle installations.
• Built-in low voltage protection at 11.4V reduces the risk of draining the vehicle battery.
• Compatible with a broad set of Rexing supercapacitor dash cam models for targeted owners.

Cons

• The included fuse type is a mini fuse that some customers find incompatible with their vehicle fuse panel and the kit only includes one mini fuse connector.
• Some users reported wiring labels and the diagram were incorrect or confusing, which can complicate DIY installation.

Our Verdict

The Rexing Smart Hardwire Kit is a practical, cost-effective way for owners of compatible Rexing supercapacitor dash cams to gain full parking mode capability without risking deep battery discharge. It offers solid protections and a long cable, but buyers should be prepared to swap the included fuse or verify wiring diagrams before a DIY install. For the right Rexing models it is good value and avoids the limitations of battery-powered units.

Frequently Asked Questions

Will this kit work with all Rexing dash cams?
The hardwire kit works with Rexing supercapacitor models listed such as V1-4K, V1P, V3, V2 Pro, V5 and S1 Series, but it is not compatible with battery models like V1 Basic, M1, M1 Pro, M2, V2, or V360.

Can I use the kit in a 24V vehicle?
Yes, the input supports DC12V-24V so it will work in most cars and light trucks with those electrical systems.

What about the fuse?
The kit includes a 15A mini type fuse; some vehicles require a different fuse adapter so you may need to connect your own fuse adapter for compatibility.
