It puts four connectors in one body: Type-C, USB-A, Lightning and Micro USB. You don't need to carry adapters or cables. At 512GB, it has room for whatever no longer fits on a 128GB or 256GB phone. However, the "USB 3.0" in the name doesn't mean every connector runs at USB 3.0 speed. iPhones and Android phones also read and write different file systems. You should know both before buying, and this article focuses on these after-purchase surprises. The body is metal (aluminum alloy). It comes with a storage case and a Japanese-language manual, and has an 18-month warranty. No dedicated app is needed: on iPhone you use the built-in Files app, and on Android you use a file manager. ## Compatibility Guide | Connector | Typical hosts | Realistic speed | |---|---|---| | Type-C | iPhone 15 and later, USB-C iPads, MacBooks, recent Android phones | Depends on the host port | | USB-A | Windows PCs, Macs with USB-A, TVs, game consoles | USB 3.0 speeds on USB 3.0 or faster ports | | Lightning | iPhone 14 and earlier, Lightning iPads | Capped at USB 2.0, because Lightning itself is USB 2.0 | | Micro USB | Older Android phones, tablets, handheld devices | Mostly USB 2.0; the device must support OTG | ### Where USB 3.0 speed actually applies You only get USB 3.0 speed on a PC's USB-A port that supports USB 3.0 or faster, or on a USB 3-class Type-C port. Lightning iPhones are limited to USB 2.0, so expect slow transfers when moving large videos from iPhone 14 or earlier. The USB-C port on the iPhone 15 and 15 Plus is also USB 2.0; only the Pro models support USB 3-class speeds. Our data doesn't list this drive's read/write speeds in MB/s, so check the product page if you need exact figures. ### Using it with an iPhone On iOS 13 / iPadOS 13 and later, the built-in Files app recognizes external drives. To move photos, select them in Photos, open the Share menu, choose "Save to Files" and pick the drive. That is all "no app required" means. To bring files back, share them from the Files app and choose "Save Image". ### Using it with Android Android devices must support USB OTG, which lets a phone power and use USB devices. Most recent USB-C phones support it, but some older Micro USB devices don't. If the drive isn't detected, check OTG support first. ### File system caveats The iPhone Files app works mainly with exFAT, FAT32 and APFS. It can't write to NTFS, the common Windows format, and Windows and Android can't read APFS. If you use the drive across iPhone, Android, Windows and Mac, exFAT is the practical choice. FAT32 limits single files to 4GB, which can block long 4K videos. Our data doesn't say how the drive is formatted out of the box. Check it on arrival, and reformat to exFAT before adding data if needed. ## Product Info | Item | Detail | |---|---| | Storage capacity | 512GB | | Interface | USB 3.0 | | Connectors | Type-C, USB-A, Lightning, Micro USB | | Compatible OS | iOS, Android, Windows, macOS | | Body material | Metal (aluminum alloy) | | Included | Storage case, Japanese manual | | Warranty | 18 months | When we checked in September 2026, Amazon. co. Prices change often with sales and stock, so check the product page before buying. That price is typical for a 512GB four-connector drive. That's a small sample and says little about long-term durability. It sits in the affordable range of external storage aimed at smartphone users. It suits people who want to keep photos at home without paying a monthly cloud fee, or move data to a new phone without a computer. ## Competitor Comparison Compare drives on three things: how many connectors they have, whether they have Apple MFi certification, and speed. | Type | Strengths | Weaknesses | |---|---|---| | This drive (4 connectors, 512GB) | One drive for old and new iPhones, Android and PCs; large capacity | No MFi certification listed; slow over Lightning | | MFi-certified Lightning drives | Apple certification gives more confidence it keeps working after iOS updates | Often smaller capacities | | USB-C-focused fast drives / SSD sticks | Much faster on USB 3-class ports; quick with large videos | Can't be used with older Lightning iPhones | Our data doesn't mention MFi certification. If stability on Lightning devices matters most, include MFi-certified drives in your comparison. If your household mixes older iPhones, Android phones and PCs, this drive's connector coverage is more practical. ## Best Use Cases * Phone storage relief: Move photos and videos off a full 128GB or 256GB phone instead of upgrading right away. It's great for people who take lots of family or travel photos, but not for frequently moving app data. * Phone upgrades: Copy photos, videos and documents from a Lightning iPhone to a new USB-C iPhone without a computer, using the same drive on both. Contacts, app settings and chat histories still need their own migration tools. * Cross-device sharing: Pass photos and files between a phone and a PC, or among family devices, with one drive and no extra cables. You probably don't need it if you only use one device. * Offline storage: Keep data in your own hands regardless of network conditions, as a one-time purchase before paying for iCloud or Google Photos plans. ## Before You Buy **Expect less capacity than 512GB. ** Manufacturers count 1GB as one billion bytes, but computers and phones count it as about 1.07 billion. The drive will normally show roughly 476GB, and that isn't a defect. **Test the full capacity while you can still return it. ** Large drives from little-known brands sold online sometimes report more capacity than they really have. We aren't saying this product does. Still, fill it completely on arrival and confirm the data reads back correctly. The worst outcome is finding a problem after your photos are already on it. **Don't make it your only backup. ** Small drives are easy to lose, and one drop or failure takes everything with it. If you delete photos from your phone after copying, keep a second copy on a PC or in the cloud. **Phone cases can get in the way. ** Thick cases, or cases with a raised lip around the port, can stop the connector from seating fully. If the drive isn't detected, try without the case. **Eject before unplugging. ** Pulling the drive mid-write can corrupt files or the whole drive. **Check the listing. ** Many sellers offer similarly named "4in1 / no app / 512GB" drives. Use the product photos and title to confirm it's the same product. At the time of writing, the listing shows Lijunga as the manufacturer, XIANGSONGKJ as the seller and ASIN B0HCZP6NXX. ## FAQ **Q. Do I really need no app on iPhone? ** A. On iOS 13 and later, the built-in Files app is enough. Save photos with "Save to Files" from the Photos Share menu. **Q. Will it be fast on an iPhone 16? ** A. The standard iPhone 15 and 16 are USB 2.0 speed even over USB-C. USB 3-class speeds need a Pro model or a PC port that supports USB 3.0 or faster. Lightning models are also limited to USB 2.0. **Q. Why can't I save a long 4K video? ** A. FAT32 limits single files to 4GB. Copy your data elsewhere, then reformat the drive to exFAT. **Q. I formatted it on Windows and now my iPhone can't read it. ** A. You probably formatted it as NTFS. Reformat it as exFAT. **Q. Can it back up my whole phone? ** A. It stores photos, videos and documents only. For a full backup including apps and settings, use iCloud or Google backup. ### Product Disclosure (Amazon) - Manufacturer: Lijunga - Seller: XIANGSONGKJ - Fulfilled by: Amazon - ASIN: B0HCZP6NXX - Note: This article covers a manufacturer-made product based on Amazon listing details.
