If you want a dedicated power stabilization unit specifically engineered to eliminate screen flickering and black screens on German vehicle rearview cameras, choose Qiilu 12V; if you need a robust connector set with pure copper inserts for upgrading or repairing mobile radios like the Yaesu FT-7800R series, choose Luqeeg TType 2. These two products serve fundamentally different niches in automotive electronics, and confusing their applications leads to frustration and wasted effort. One is a specialized filter designed to clean up unstable voltage for video feed clarity, while the other is a physical interface kit designed to ensure reliable electrical contact for high-power radio equipment. Understanding this distinction is the only way to make the right call before you buy.
• Qiilu 12V: Its biggest strength is solving specific voltage instability issues for rearview cameras by filtering pulsing interference directly from the reversing light circuit. Its biggest trade-off is that it is strictly limited to German car series and will not function on non-pulsed systems or other vehicle makes. This pick is for owners of German vehicles struggling with camera signal corruption.
• Luqeeg TType 2: Its biggest strength is providing a durable, low-resistance connection path using pure copper inserts within an ABS housing, ensuring stable power delivery to high-draw radios. Its biggest trade-off is its narrow compatibility, being tailored almost exclusively for the Yaesu FT-7800R, FT-8800R, and FT-8900R models. This pick is for radio enthusiasts who need a secure upgrade for their existing T-Type harnesses.
The Qiilu 12V DC Car Rearview Camera Power Relay Capacitor Filter Rectifier is not a general-purpose adapter; it is a surgical tool for a very specific problem. The core issue it addresses is the "screen cyclowarp" or "black screen" phenomenon that occurs when the working voltage from a car's reversing light is too unstable for a modern camera to handle properly. In many vehicles, especially those with complex electrical architectures, the voltage spikes or fluctuates as soon as the reverse gear is engaged. Without a stabilizer, the camera receives this erratic power, causing the video output to glitch, freeze, or disappear entirely. This component sits between the reversing light and the camera, acting as a capacitor and rectifier to smooth out those pulses and deliver a clean, stabilized 12V DC supply.
This product is explicitly designed for the German car series market. If your car falls into this category, the Qiilu unit can be a lifesaver, turning a frustrating, unusable backup camera into a reliable safety feature. The installation process is straightforward but requires precise wiring: the input red wire connects to the reversing light positive pole, the input black wire to the negative, and the outputs connect directly to the camera's positive and negative lines.

However, you must skip this product if your vehicle is not part of the German car series. The manufacturer explicitly warns that the device relies on detecting and managing pulsed interference patterns specific to these brands. If you drive a Japanese, American, or Korean brand where the reversing light system does not produce the same type of pulsing interference, this filter line is invalid and will do nothing for your camera. It is also not a universal fix for all camera issues; it solves power instability, not lens damage or sensor failure. If you own a German vehicle and are tired of your backup screen going black every time you put the car in reverse, this is the solution you need.
The Luqeeg TType 2 Pin Power Plug Car Radio Connectors Set is built for the serious operator who treats their mobile radio as critical infrastructure. This isn't just a plug; it is a complete overhaul of the connection point to maximize efficiency and longevity. The kit includes five male connectors, five female connectors, and twenty copper sheets, offering a comprehensive package for upgrading an entire setup. The design philosophy here centers on durability and conductivity. By combining an ABS plastic housing with pure copper inserts, the manufacturer aims to reduce contact resistance significantly compared to standard brass or lower-quality metal contacts often found in factory harnesses.
This product shines when paired with high-performance amateur radio transceivers like the Yaesu FT-7800R, FT-8800R, and FT-8900R. These radios draw significant power, and any resistance in the connection can lead to heat buildup, signal loss, or even melted connectors during extended transmission periods. The pure copper inserts mentioned in the specs are key here; they ensure a reliable power connection that can handle the heavy current loads without degrading over time. The "T-Type" designation refers to the specific pin configuration required by these popular radio models, making this a direct replacement or upgrade for users who have outgrown their stock cables.
Installation is marketed as simple and tool-free, which appeals to DIYers who want to upgrade their rig without needing a soldering iron or crimping tools. The ABS material provides a sturdy shell that protects the internal copper components from vibration and impact, common in a moving vehicle environment. However, the utility of this set is entirely dependent on your radio model. If you are using a different brand or a radio that uses a different connector style, this kit is useless. It is not a universal power cable; it is a precision fit for a specific ecosystem of Yaesu equipment. If you are a ham radio enthusiast looking to eliminate connection anxiety and ensure your radio gets exactly the power it needs, this set is the logical choice.
• Best for eliminating camera flicker → Qiilu 12V (specifically for German cars with unstable reversing lights).
• Best for radio power reliability → Luqeeg TType 2 (for Yaesu FT-series rigs requiring high-current stability).
• Best for German vehicle owners → Qiilu 12V (the only one compatible with the specific electrical architecture of these cars).
• Best for Ham Radio upgrades → Luqeeg TType 2 (designed for the specific T-Type interface of popular mobile radios).
• Best for ease of installation → Both offer simple wiring/connector methods, but Luqeeg is a plug-and-play connector swap while Qiilu requires cutting into the reversing light circuit.
• Best for component durability → Luqeeg TType 2 (uses pure copper inserts for long-term conductivity under load).
• Best for preventing black screens → Qiilu 12V (actively filters voltage spikes that cause display failures).
• Best for comprehensive kits → Luqeeg TType 2 (includes multiple connectors and spare copper sheets for redundancy).
In my opinion, the decision comes down entirely to whether you are trying to fix a video display issue or upgrade a communication link. If I were preparing a vehicle specifically for car detailing, where seeing the rear bumper clearly is vital for parking tight spaces and avoiding scratches, I would immediately choose the Qiilu 12V. The ability to guarantee a stable, flicker-free image on a German car is non-negotiable for a professional detailer who cannot afford to miss a curb or a post. However, if I were setting up a mobile command station or operating a high-power radio from a vehicle, the Luqeeg TType 2 would be my pick due to the superior conductivity of its copper inserts. For the average buyer torn between these two, remember: Qiilu saves your view, while Luqeeg secures your voice.
No, the manufacturer explicitly states this filter is invalid for non-pulsed interference systems found in non-German car series. It will not solve voltage issues if your vehicle does not match the specific electrical profile it is designed for.
They are designed for the T-Type interface used by these units and may not fit other radio brands without modification.
The Qiilu 12V is designed to stabilize voltage to prevent screen cycling and black screens, not to boost brightness or enhance image resolution. Its function is purely power regulation to ensure the camera operates within its normal parameters.
Yes, the set includes 20 copper sheets alongside the connectors, allowing for replacements or repairs if a connection becomes loose or worn over time, ensuring long-term maintenance capability.
