Accomplished this with fully formed and sealed connector heads paired with high-grade, UV-resistant PVC jacketing for the jacket body of the cable. We provide two of the most popular connector sizes to support a variety of devices: the 5.5×2.1mm DC Power Cable and the 3.5×1.35mm DC Power Cable. They are available in male-plug and female-socket form factors, so you can bolster your power distribution system with hot-swap capabilities. Cable ends are provided as stripped and tinned tails to facilitate rapid, reliable soldering or screw terminal connection, so the savings in installation time can be considerable.


18AWG & 22AWG Copper Conductor
But it’s not just a tough shell; the build internally ensures effective power transfer. The 5.5×2.1mm variant uses a thick 18 AWG pure-copper conductor, making it suitable for higher-power type applications such as security camera power or high-power LED light bars. The 3.5×1.35mm version uses a premium-quality 22 AWG copper conductor, well-suited to low-power devices such as dash cams or small sensors. Measuring in at the standard 25cm, these cables are designed to give you a sealed link between a waterproof junction box and your equipment! If you need an alternative solution, even one that extends a run, we also manufacture DC Power Extension Cables and other DC Power Cords.
Engineered for Fast, Reliable Installation
In professional installations, time is indeed money. Our Waterproof DC Power Cable makes wiring a breeze. The cable ends are provided as stripped and tinned tails, eliminating the painful process of measuring, cutting, and stripping insulation yourself. The preliminary preparation enables direct soldering to terminals or other wires, resulting in a stronger electrical bond while saving precious labor hours. The 5.5×2.1mm male and female connectors also make connections easier, eliminating setup errors for outdoor CCTV systems, marine electronics, and lighting projects—getting your systems working faster.


Built Tough for Demanding Environments
Components in outdoor and industrial settings need to be ruggedized for the outdoor environment and also withstand vibrations, etc. It is specifically designed to resist wear and high pressure. It has a rugged, black, UV-resistant PVC jacket to protect against abrasion, sun degradation, and minor impacts. Together with the connector head, which is sealed and rated to IP67, this assembly is protected against dust and moisture, as well as temporary submersion. The durable, waterproof DC power cable addresses the critical pain point of early cable failure in harsh conditions — it features sturdy construction to ensure long-term reliability and lower maintenance costs for your outdoor deployments.
A Versatile Solution for Site Power Across Many Industries
Our Waterproof DC Cable offers great versatility, providing a single-sourcing solution for multiple B2B applications. It comes in two of the most popular sizes: 5.5×2.1mm for high-current output and compact 3.5×1.35mm—in male-plug and female-socket styles to meet a broad range of needs. Whether powering IP cameras and LED billboards for security and advertising, or connecting sensors and devices for industrial automation and marine electronics, this cable delivers sealed, reliable power. With its broad applicability, it takes the guesswork out of keeping such inventory for integrators and distributors who now need only a single ruggedized or outdoor 12V/24V power connection product line for hundreds of applications.

The IP67 certifies the cable’s connector as dust-tight and waterproof. This makes it a great choice for outdoor, marine, or wet environment applications.
The main ones are connector size and current capability. The 5.5×2.1mm size uses 18 AWG wire, and for higher-power devices, such as security cameras and light bars. The 3.5×1.35mm model with 22 AWG wire is good for low-power, small devices (dash cam, GPS unit).
Yes. Both models come with bare, tinned wire leads. Tinning prevents copper oxidation and allows terminals or other wires to solder much faster, easier, and reliably.
Absolutely. You would typically use a male plug cable plugged into a power source (inside a waterproof enclosure) and a female socket cable connected to the device. The IP67-rated connectors seal the connection point when mated.
The IP67 sealed connector assembly is rated to withstand dust and water ingress. The actual cable has a solid, heavy feel and is covered with durable, high-quality PVC that is water-resistant and suitable for outdoor use; the primary waterproof seal will be at the connector end.
It fits any DC application outdoors or in a hostile environment. Typical uses include outdoor CCTV camera connections, marine electronics in the boat’s power system, wiring for outdoor LED light strips, industrial automation sensors, and other devices.
An 18AWG wire is thicker than a 22AWG wire and carries more current for longer distances with less voltage drop compared to thinner wires. That’s important for running things such as motorized security cameras or long runs of LED lights designed to operate on stable, higher-current power; the devices need to operate at full capacity.
Yes. Bespokecable is a custom cable solution direct from the factory. These Waterproof DC Cables can be custom-made to any length, wire gauge, or jacket color from 25cm (8 inches) on for bulk and OEM orders.
You can add another layer of protection on top of the IP67 connector.

More About Waterproof DC Power Cable of Bespokecable
Quality Control
As a manufacturer, implement a strict quality control system that spans from component sourcing to final inspection for the IP67 Waterproof DC Power Cable. We exclusively use certified wires, including pure-copper guides, for optimal current flow, and high-grade PVC resistant to UV rays for the cable jacket. The IP67 ingress protection test is the most important of them all; in this test, assembled connectors are exposed to dust and water under a high-pressure water jet and to temporary immersion to verify seal integrity. Routine continuity and high-pot (hipot) testing are performed on each unit to guarantee operational excellence and electrical insulation safety. A mechanical pull test is applied to the strain relief to confirm that the cable can withstand the tension of installation and environmental stress. This process is multi-level verification, meaning each Waterproof DC Power Cord, 5.5×2.1mm and 3.5×1.35mm, delivers dependable, rugged performance for mission-critical outdoor and industrial uses, giving our B2B partners confidence.

You can also customize your IP67 Waterproof DC power cable to match your product form factor, environmental challenges, and performance needs, resulting in a more efficient supply chain.
How to Install A Waterproof DC Power Cable?
A right installation of a Bespokecable Waterproof DC Power Cable to ensure it has an IP67 protection rating and can be used for a long time. Here is a professional step-by-step guide:
- Preparation: Locate the tinned wire tails (red positive, black negative). Try to keep the mating connector (plug or socket) on the other end clean and dry.
- Connecting to Device: Attach the tinned tails to your power supply or device terminals. The best option is soldering for a permanent, non-corrosive bond. Instead, you may use a suitable insulated wire connector or terminal block with a high rating based on anticipated current and environmental conditions. Provide a mechanical connection that is tight and secure.
- Now, for caulking the connection (also essential for waterproofing): After doing this wiring, you have to apply a secondary seal. If you need the best possible protection for the splice, use adhesive-lined dual-wall heat-shrink tubing over the entire splice region. Wait for the heat to cause the adhesive to flow and motorway tubing to shrink, sparingly lid’d waterproofing. Or put the fully made connection into a different IP-rated junction box.
- Insert the Connectors: Slide male and female Waterproof DC Jack Cable connectors into place until you hear or feel a decisive click, which indicates that the O-ring inside has properly sealed. Hand-tightened threaded coupling nut (if present) to lock the connection against vibration.
- Last Check: Do a final visual check before turning on the system to ensure that any seals are intact and connections are in place.

The Ultimate B2B Buyer’s Guide to the Waterproof DC Power Cable
Choosing the correct Waterproof DC Power Cable is crucial for the safety and reliability of outdoor, marine, and industrial equipment. This guide is provided by Bespokecable – a preeminent factory and manufacturer of custom connectivity solutions for this purpose- to help engineers, system integrators, and wholesale buyers make an informed decision. If you’re powering Waterproof CCTV systems, LED strips, or any other marine electronics, the first step to avoiding field failures is to understand IP ratings, conductor specs, and connector types.
1. IP Ratings: What IP67 and IP68 Mean for Outdoor Use
Ingress Protection (IP) is the most important specification of any outdoor DC cable. It specifies the protection rating against dust and water.
- IP67 (Standard for Most Outdoor Applications): Dust-tight and temporary immersion in water to 1 meter for 30 minutes. For most Outdoor Waterproof DC Cable applications, such as security cameras (Waterproof CCTV DC Power Cable) and Waterproof LED Strip DC Cables, this is usually good enough since the only exposure comes from rain & splashing.
- IP68 (For Harsh & Submersion Environments): An IP68 Waterproof DC Power Cord is suited to protection for continuous submersion up to a specific performance depth (depending on its application, such as where it sits in ponds, marine docks, or underground conduit). For applications where there is constant water exposure, such as a Marine Waterproof DC Cable for boat bilge pumps or underwater lighting, insist on IP68.
Pro Tip: Test conditions for IP68 vary by manufacturer, so be sure to check that depth and duration are all that information is in place before opening the package! Our IP67-rated cables offer the strongest combination of performance and price for most land-based projects.
2. Working with a matching connector size and polarity with your device
Mistakenly using the wrong connector is a common cause of installation headaches. Their most used sizes for DC power connectors are:
- DC 5.5×2.1mm (High Current): This is the industry standard for higher power uses. Widely used for Waterproof CCTV DC Power Cable runs, Outdoor LED displays, and Waterproof DC Extension Cables. While sourcing, verify the polarity is usually center-positive to protect sensitive electronics.
- DC 3.5×1.35mm (Low Profile): This small connector is used in dash cams, portable devices, and low-watt sensors. Make sure to tell them which one you need for a solid connection.
If your project requires other lengths and connectors, simply use our OEM/ODM services to obtain dried cables, pinouts, or housing specifications.
3. Wire Gauge (AWG) and Material (The lower the wire gauge, the thicker the wire – this avoids a voltage drop.)
A thin cable will cause a voltage drop, a dim LED, or an optional camera not working! The wire gauge also needs to be appropriate for the current draw and the run length.
- 18AWG (for 5.5×2.1mm): This thicker gauge is best for runs longer than a few meters or for devices with power draws over 3-4 amps. It provides a stable voltage supply for power-hungry equipment.
- 22AWG (for 3.5×1.35mm): Designed for shorter runs and lower current needs, while allowing little space for devices.
- Material Matters: Always demand pure copper conductors. Even though CCA wires are cheaper to sell, they have higher resistance and tend to fail outdoors. Determining the material of the conductor is an indispensable quality check for bulk purchases.
4. Jacket Material and Environmental Durability
First of all, the jacket is your first line of defense against the weather. Authentic Outdoor Waterproof DC Cable: What to Look for
- UV resistance: Regular PVC will wear out and develop fractures if exposed to sunlight. This is a high-quality PVC that offers long-term flexibility and excellent UV stability.
- Temperature rating: Make sure the cable you select is rated for your local climate extremes, especially in solar or rooftop applications where ambient temperatures can get extremely high.
- Abrasion Resistance: In cabling routed through conduits or subjected to vibration, it helps reduce wear.
5. Application-Specific Selection Guide
- Security & CCTV: waterproof CCTV DC Power Cables, outdoor-use IP67 5.5×2.1mm cables, 18 AWG copper. This provides a solid connection from the junction box to your camera—even in heavy rain.
- LED Lights: Waterproof LED Strip DC Cables that need to block moisture from wicking up into the solder points in the strip may require tight-sealing connectors. Something like a good strain-relief collar, a waterproof DC jack cable.
- Marine & Solar: Corrosion resistance is the most important for connections in solar panels and Marine Waterproof DC Cables. Find tinned copper conductors and IP68 ratings. This might be a Standard DC barrel plug for small runs (a Smart connector right at the panel), but for longer distances, use a Solar Panel Extension Cable with MC4 or other weatherproof connectors.
6. Collective Sourcing Strategy: Off-the-Shelf or Custom OEM?
- Wholesale/Bulk Buyers: If your project utilizes our standard 5.5×2. 1mm or 3.5×1. Buying standard-length Waterproof DC Power Cords in bulk from a manufacturer such as Bespokecable is the cheapest way to get 35mm connectors.
- OEM/ODM Projects: If your product needs a color, length, or connector type (such as a locking connector), you are looking for an OEM/ODM project solution to buy Wire Harness and cable according to your BOM. It also reduces the need to make changes in the field and guarantees brand uniformity.
