FAQ
Q: How to use a USB flash drive chip?
A: A USB flash drive chip (COB/UDP chip) is the bare, un-cased core of a USB drive.Asemble the COB chip into a compatible USB casing (plastic/metal/swivel).Plug into any USB port,such as computer, TV, car stereo, etc. Then you can use it to copy files. Can also format the usb flash chips to delete all of the files with format:FAT32(Best for car stereos, TVs)and cross-platform use (supports files ≤4GB).
o exFAT: For large files (>4GB) on Windows/Mac.
o NTFS: Best for Windows-only use (supports large files/security).
How to format: Right-click drive → Format → Choose file system → Start.
Q: Why are flash drives becoming obsolete?
A: In fact, flash drives are not declining or becoming obsolete at all - their usage has simply evolved.
While cloud storage, wireless file sharing, and high internal storage on phones and laptops have reduced everyday personal use, flash drives have grown into a powerful tool for brand building, business promotion, and corporate gifting.
Today's USB flash drives are far less about casual personal file transfers and much more about branded marketing and professional image-building, especially across these key scenarios:
• Promotional companies use custom flash drives to preload brand videos, product catalogs, and marketing materials for giveaways.
• Businesses distribute branded flash drives to clients at trade shows, exhibitions, and corporate events as professional, practical gifts.
• Companies and organizations present them as conference gifts, VIP handouts, and souvenir gifts to enhance brand recognition.
• Mobile accessory brands use custom flash drives to strengthen brand identity and expand product lines.
• Stationery, training, and educational institutions use preloaded flash drives to deliver course materials, training resources, and promotional content.
In short, flash drives have shifted from a daily personal storage item to a portable, tangible branding medium - one that keeps a company's image and content physically with the recipient, making them more valuable than ever for business and marketing use.
Q: What does a flash chip do?
A: A flash chip is the core component that **permanently stores digital data like photos, files and videos without power**.
It uses tiny "floating gates" to trap or release electrons, representing digital 0s and 1s.
- **Store**: Keeps data safely for years when unplugged.
- **Write**: Saves new data by charging cells with electrons.
- **Read**: Recovers files by detecting electron patterns.
- **Erase**: Frees space by removing electrons.
Q:How do you know your usb flash drive comes full capacity or not?
A: High-quality flash chips ensure stable storage, real capacity and no data loss, while cheap recycled chips cause errors and fake capacity. We only use branded flash chips and test all products with H2testw for reliability.
Q: Why do 2.0 USB devices not work in 3.0 USB ports?
A: USB 2.0 devices are theoretically backward-compatible with USB 3.0 ports, and failures usually result from poor contact, driver issues, power differences, motherboard settings, or low-quality device chips.
Actual capacity less than marked value
The system uses binary calculation (1GB=1024MB), while manufacturers use decimal (1GB=1000MB). A small capacity is reserved for the controller. This is normal for all flash products, and we guarantee real full capacity.
