Products Description
Our U3 TF Card to solve the core pain points of users and B2B customers: fake capacity, unstable performance, slow transfer speeds, and poor durability. Unlike inferior TF cards on the market that use upgraded chips to fake capacity (e.g., a 1GB card disguised as 32GB), our tf card u3 uses 100% original flash chips, ensuring true full capacity and reliable performance for long-term use. This high-performance TF card supports U3 speed class and UHS-I interface, with a read speed of up to 100MB/s and a write speed of 30MB/s (actual test range: read 70-95MB/s, write 10-35MB/s), perfectly meeting the needs of 4K video recording, continuous surveillance, and fast data transfer. Whether you're using it for a dash cam, surveillance camera, smartphone, drone, or Gopro, this TF card delivers stable, efficient performance even in extreme environments. We pride ourselves on transparency and quality-every card undergoes strict testing with H2test2 software to verify true capacity, ensuring you and your customers never fall victim to fake or upgraded cards.
Material
The U3 TF card is in high-grade components to ensure our U3 TF Card outperforms competitors in lifespan and reliability:
Flash Chip: 100% original flash chips (from top-tier suppliers like Samsung, Toshiba, and SanDisk). This ensures the card maintains stable performance even after years of frequent use (e.g., 24/7 surveillance recording).
Shell Material: High-quality engineering plastic (PC+ABS composite). This material is waterproof (IPX7), dustproof, and shockproof.It also has excellent heat resistance, which is stable in temperatures ranging from -25℃ to 80℃-critical for in-car environments (where temperatures can reach 75℃ in summer) and outdoor surveillance.
Connector: Gold-plated copper contacts. The gold plating reduces resistance by 15%, ensuring fast, stable data transfer and preventing corrosion. To make it ideal for devices that require frequent card changes (e.g., cameras, drones).
Circuit Board: High-precision PCB board with anti-interference design. This minimizes data loss and errors during transfer, especially important for 4K video recording and continuous surveillance. The PCB board is also resistant to x-rays, ensuring it remains undamaged during airport security checks.

Products Appearance
Our U3 TF Card features compact, minimalist that fits all standard TF card slots.
Size & Shape: Standard TF card dimensions: 15mm (L) × 11mm (W) × 1mm (H)-the smallest form factor for memory cards, making it a mini memory card that fits seamlessly into smartphones, dash cams, surveillance cameras, and other small digital devices. The card has a smooth, flat surface with rounded edges to avoid scratching device slots.
Markings: Clear, laser-engraved markings on the card surface, including capacity, speed class (U3, Class 10), and brand logo (customizable). The laser engraving is durable and easy to read, helping users quickly identify the card's specifications.
Packaging Compatibility: The card is designed to fit standard mini PP cases with an SD card adapter (included in standard packaging), making it compatible with devices that use SD card slots (e.g., cameras, laptops).
Products Design
Every design detail of our U3 TF Card is for performance, compatibility, and user convenience, addressing the shortcomings of peer products:
True Capacity Design: We strictly avoid "upgraded" or fake capacity-every card is tested with H2test2 software to ensure 100% true capacity. For example, our 128GB card actually stores 128GB of data (not 64GB disguised as 128GB), preventing data loss and customer complaints. This is a critical advantage over competitors who cut corners with fake capacity.
U3 Speed Class Design: Optimized for high-speed data transfer and 4K video recording. The U3 speed class ensures a minimum write speed of 30MB/s, which is required for smooth 4K video recording. For example,the U3 TF card for a Gopro Hero 10: records 4K/60fps video without stuttering or frame drops, making it the best sd card for gopro hero 10).
Multi-Format Compatibility: Designed to support FAT32 (128MB-32GB) and exFAT (64GB-1TB) formats, ensuring seamless compatibility with all devices. The exFAT format supports files larger than 4GB, which is essential for storing 4K videos and large photos.
Extreme Environment Design: Built to withstand harsh conditions-waterproof (IPX7), dustproof, shockproof, x-ray resistant, and temperature resistant (-25℃ to 80℃). This design makes it ideal for in-car dash cams (withstands high temperatures), outdoor surveillance cameras (resists rain and dust), and drones (handles vibrations during flight).
OEM-Friendly Design: The card's surface is optimized for logo printing (silk screen or laser engraving), with enough space for custom brand logos and specifications. The compact size and standard shape make it easy to customize without affecting compatibility.
Products Features & Advantages
Our U3 TF Card stands out from competitors with the following core advantages, backed by real data and testing:
True Full Capacity: Every card is tested with H2test2 software to verify 100% true capacity-no fake or upgraded cards. For example, our micro sd 128gb class 10 card actually stores 128GB of data, allowing users to store up to 25 hours of 1080P video or 30,000 high-resolution photos without data loss. This is proven by our 100% testing process, with a 0% fake capacity rate.
High Speed Performance: Read speed up to 100MB/s (actual test: 70-95MB/s), write speed up to 35MB/s (actual test: 10-35MB/s). This allows for fast data transfer-transferring a 1GB video from the card to a computer takes only 10 seconds (vs. 30 seconds for inferior cards with 30MB/s read speed). The U3 speed class supports smooth 4K video recording and continuous surveillance.
24/7 Stability: Designed for continuous read/write operations, making it ideal for dash cams and surveillance cameras. It supports repeated earsing,monitoring video is easy to store,free to call,use more peace of mind.
Extreme Durability: Waterproof (IPX7), dustproof, shockproof (2-meter drop), x-ray resistant, and temperature resistant (-25℃ to 80℃). We tested the card in a car environment (80℃ for 72 hours) and found no performance degradation-critical for dash cams in hot climates. It also withstands vibrations from drones and impacts from drops, making it perfect for outdoor use.
Wide Compatibility: Works seamlessly with all devices that support TF cards, including smartphones, tablets, dash cams, surveillance cameras, drones, Gopro cameras, GPS devices, MP3/MP4 players, and medical devices. We tested the card with 50+ popular devices (e.g., iPhone 15, Samsung S24, Gopro Hero 10, Dahua surveillance cameras) and found 100% compatibility.
Large Capacity Options: Available from 128MB to 1TB, meeting all storage needs-from small capacity for MP3 players to 1TB for 4K cameras and drones. The 1TB capacity can store up to 200 hours of 1080P video or 250,000 high-resolution photos.
Data Security: Supports repeated erasing (10,000+ cycles) and has built-in error correction technology to prevent data loss. This is especially important for surveillance cameras and dash cams, where data integrity is critical for legal and security purposes.
Cost-Effective: As a direct manufacturer, we offer high-quality cards at competitive prices-our U3 TF Card is 15-20% cheaper than brand-name cards with the same performance, making it ideal for B2B customers (distributors, retailers, promotional companies).
