Overview
The NYANDELMO ND-0494-R01 is a 20-pack of clear USB-C dust plugs designed to protect charging and data ports on a wide range of devices. Each cap measures approximately 1.1 x 0.9 x 0.5 cm and features a small metal ring for easy removal. The clear finish with a silver ring makes them discreet while still being functional, ensuring your device's design isn't compromised. This product is aimed at users who want a simple, affordable way to keep dust, lint, and debris out of their USB-C ports. Whether you're using a smartphone, tablet, laptop, power bank, or game controller, these caps offer a basic but effective layer of protection. Priced at around ¥749 (approx. $5 USD) on Japan, they deliver excellent value per cap, especially for households with multiple devices.
Connectivity & Compatibility
The ND-0494-R01 is compatible with any device that features a standard USB Type-C port. This includes modern smartphones (both Android and iPhone 15 series and later), tablets (iPad Pro, iPad Air, etc.), laptops (MacBook, Dell XPS, ThinkPad, etc.), power banks, wireless earbuds cases, Nintendo Switch, PlayStation 5 controllers, digital cameras, and more. Installation is straightforward—simply insert the cap into the port. The fit is snug but not overly tight, and the cap stays in place during normal handling. However, if your device has a thick case or protective cover, ensure there is enough clearance around the port for the cap to fit properly. Removal is easy thanks to the attached ring.
Product Info
The NYANDELMO ND-0494-R01 was released in early 2025 and is primarily sold through Japan. It is an entry-level accessory with a price tag of about ¥749 for a pack of 20 caps. No additional accessories or instructions are included—just the caps. Warranty is handled by 's standard A-to-Z Guarantee. In the market, this product sits in the budget-friendly segment of USB-C dust caps. It competes with similar offerings that often come in smaller quantities (5 or 10 packs) at higher per-unit costs. With 20 caps at this price, the value proposition is strong for users who need to protect multiple devices or want spares for travel and work. Build quality is decent; the plastic is smooth without rough edges, and the ring is securely attached.
Best Use Cases
This product is ideal for the following scenarios: Frequent travelers and commuters: If you carry your phone, tablet, and laptop in a bag or pocket, dust and lint from the environment can easily enter the USB-C ports. Using these caps prevents debris accumulation, reducing the risk of poor contact or charging issues. The 20-pack means you can keep caps in multiple bags or share with family. Desktop organization enthusiasts: Users who prefer a clean, dust-free workspace will appreciate covering unused USB-C ports on their PC, monitor, or docking station. The clear caps blend in and don't attract attention, maintaining a minimalist aesthetic. Gamers with multiple controllers: Whether it's a Nintendo Switch, Xbox wireless controller (on newer models), or PS5 DualSense, these controllers use USB-C for charging. Caps protect the ports when not in use, especially if you store controllers in drawers or cases where dust can settle. Tech enthusiasts who like to be prepared: Because the caps are small and easy to lose, having 20 in stock means you'll always have replacements available. They are also perfect for gifting—you can give a few to friends who are always complaining about dirty ports. On the flip side, this product is less suitable for users who already have a case that covers the port, or those who simply don't mind a bit of dust in their ports. Also, if you prefer a colored cap that matches your device (e.g., black or white), be aware that this pack only includes clear caps with a silver ring.
