If you want a tidy, clutter-free charging hub for everyday commuting and light device loads, choose BERTHALESS Retractable Car Charger; if you need massive power to run high-performance laptops and multiple gadgets simultaneously while overlanding, choose NKNZLY 170W.
• BERTHALESS Retractable Car Charger: Its biggest strength is the compact, retractable cable design that keeps your car interior organized without sacrificing basic functionality; its trade-off is lower total wattage output, which limits it to phones and tablets rather than heavy-duty computing gear. This pick is for the driver who prioritizes a clean cabin and simple phone charging needs.
• NKNZLY 170W: The standout feature here is the massive 170W total power distribution across four ports, including dual high-wattage USB-C cables capable of powering laptops; however, this comes with a more complex interface and a larger physical footprint that might feel bulky in smaller vehicles. This option is for the tech-heavy user or overlander who demands speed and raw power for everything from smartphones to MacBook Pros.
The BERTHALESS unit shines as a practical solution for drivers who value organization above all else. Its core design philosophy revolves around eliminating the "cable jungle" that often plagues vehicle centers consoles. This mechanism ensures that when you aren't actively charging, the charger sits flush and unobtrusive, maintaining a sleek aesthetic that many other bulkier adapters lack.
For the average commuter or family driver, this 4-in-1 adapter covers the essentials without overwhelming the system. It features a combination of USB-A and USB-C ports, allowing you to plug in an older Android phone alongside a newer iPhone or tablet. The smart protection system guards against overcharging, excessive current, and overheating, providing a layer of safety that is crucial for overnight parking or long drives where you leave devices plugged in. The 180-degree adjustable direction adds a nice touch of flexibility, letting you angle the head so it doesn't block adjacent controls or vents in tight spaces.
However, this product is not built for high-demand scenarios. If you plan to charge a laptop while driving, or if you have a large group needing simultaneous power, the wattage capabilities of this unit may fall short compared to more aggressive alternatives. It is designed to keep your smartphone, GPS, and perhaps a tablet running smoothly, but it lacks the raw horsepower required for power-hungry electronics. Consequently, this is the ideal choice for someone whose primary goal is to keep their car interior neat and ensure their mobile devices stay charged during daily errands or weekend trips, without the need for heavy-duty computing equipment on the road.

The NKNZLY 170W model is engineered for a completely different demographic: those who treat their vehicle as a mobile office or a command center for extended travel. The headline feature is the sheer amount of power available. With a maximum output of 170W split across four ports, including dual retractable Type-C cables rated for 65W and 45W respectively, this charger can handle the most demanding tasks. You can fast charge a flagship smartphone while simultaneously powering a MacBook Pro or charging a high-capacity drone battery without worrying about the system dropping speeds or failing to deliver energy efficiently.
Beyond raw power, the NKNZLY integrates intelligent monitoring tools that are essential for serious travelers and overlanders. The built-in LED display provides real-time voltage monitoring, giving you instant feedback on your vehicle's battery health while you drive. This is a critical feature for anyone heading off-grid or spending long hours in a vehicle, as it allows you to track whether your alternator is keeping up or if you are drawing too much power. The inclusion of soft ambient lighting also solves a common problem found in other chargers: locating ports in the dark. Instead of fumbling in the gloom, the light illuminates the area, adding a premium feel to the interface.
This unit is also built for stability and versatility. The 180-degree rotation base ensures a firm connection even on bumpy roads, preventing the loose wobble that can occur with cheaper adapters. It fits securely in standard 12V to 24V sockets, making it compatible with cars, SUVs, and trucks. If you are an overlander carrying cameras, laptops, and multiple communication devices, or simply a professional who needs to work from your vehicle, this charger is the only logical choice. It transforms the cigarette lighter socket into a powerful, reliable hub that can support a full suite of modern electronics.

After analyzing the specifications and intended use cases for both units, I would buy the NKNZLY 170W if my primary goal was to prepare for an overlanding trip. The ability to monitor vehicle voltage and the sheer capacity to charge a laptop alongside multiple phones is a game-changer for remote travel where power sources are scarce. However, for a standard daily commute where I just need my phone charged and want to avoid cable clutter, the BERTHALESS Retractable Car Charger remains a fantastic, no-nonsense tool. Ultimately, if you need power to work or explore, go with the NKNZLY; if you just need convenience for your phone, the BERTHALESS is the smarter, tidier choice.
Yes, the NKNZLY 170W features a smart LED display that tracks your car's battery voltage in real time, allowing you to monitor electrical health while driving. The BERTHALESS model does not include this specific monitoring feature.
Only the NKNZLY 170W is designed to handle high-power laptops such as MacBook Pros, thanks to its 65W and 45W dual USB-C retractable cables. The BERTHALESS is optimized for phones and tablets with lower power requirements.
Both utilize retractable designs to eliminate tangled cords, but the BERTHALESS is often preferred for its simpler, non-digital appearance, while the NKNZLY adds ambient lighting and a voltage screen which some users find useful but others consider additional visual noise.
