Bawanfa Plus 4in1 OTG Adapter, Flash Drive & TF/SD Card Reader for iPhone
Product description
What it is
This 4in1 OTG adapter combines SD/TF card reading with USB-C, USB-A and Lightning connectors in a single compact unit. It’s designed for photography creators who want a straightforward way to transfer files between cameras, phones, tablets and laptops without juggling multiple dongles. On paper, it promises plug‑and‑play operation, two‑way transfer, and simultaneous charging while reading, which can be handy during long shoots.
Who it’s for
If you shoot with a DSLR or action camera and use an iPhone, iPad or Android device, this reader aims to reduce the hassle of moving files from memory cards to your device. It’s also pitched at those who want a single, portable solution for both data transfer and USB expansion in one package. Depending on your workflow, this could simplify kit and minimise fumbling with adaptors on site.
How it works in practice
The 3‑connector design (Lightning, USB‑C, USB‑A) covers most of your devices, so you don’t need separate adapters for phones, tablets or laptops. It supports SD, SDHC, SDXC and MicroSD/microSDHC/microSDXC through the card slots, and it advertises transfer speeds of roughly 60–90 MB/s when moving files to a device. You can also power a device via the USB‑C charging port while data transfers occur, which helps avoid interruptions if your phone’s battery is running low during a shoot.
What stands out in use
On the plus side, the all‑in‑one approach cuts down the number of items you carry and swap between. The inclusion of a USB‑A and USB‑C female port adds flexibility—you can connect USB drives, keyboards or even some peripherals if your setup calls for it. This can be handy when backing up photos directly to a drive or when using a camera as a source for quick edits on a tablet.
Considerations and limits
It’s not perfect, and you may want to temper expectations. OTG support can vary by iOS version, with iOS 13 and above you get full OTG functionality, but older iOS versions may limit certain features like reading office files or using USB peripherals beyond a keyboard. The device lists support for a broad range of memory cards, but actual performance depends on card quality and file size. If you rely heavily on continuous high‑speed transfers, the stated 60–90 MB/s may feel slow compared with dedicated card readers or wired camera fast transfer workflows.
Compatibility and what you’ll note in reality
This reader targets users who want a single, travel‑friendly solution and are comfortable testing compatibility with their devices. In practice, if you primarily shoot with a camera and want to offload to an iPhone for quick sharing, it can help, if your needs are consistently high‑volume or require uninterrupted 4K video transfer, you might encounter limits and should consider alternatives tailored to your card type and device ecosystem.
How it compares to other approaches
Compared with separate adapters or a standalone card reader, this 4in1 design trades peak performance for convenience and portability. For casual editors and on‑the‑go creators, the convenience can outweigh the speed trade‑offs. For intensive photographers or those who value fastest possible transfers, a dedicated card reader or direct camera‑to‑device workflow could be more efficient.

Quick start tips
1) Check that your card is formatted correctly for the device you’re using (often FAT32/exFAT depending on size). 2) If your device doesn’t recognise a card, try reformatting on a computer or using a different card, not all speeds are equal. 3) If you plan to charge while transferring, ensure you’re using a suitable charger and cable to avoid heat build‑up during long transfers.
FAQ (practical answers)
- Will it work with my iPhone running the latest iOS? Yes, iOS 13 and above supports full OTG on compatible devices, but capabilities may vary by app and file type.
- Can I transfer video files directly to my iPad? Yes, if the file types are supported and the file system is compatible with the iPad’s reader.
- Do I need software to use it? No third‑party apps are required for basic reading and transfer, it’s designed to be plug‑and‑play.
Is it worth it?
A solid pick if you prioritise portability and the convenience of a single 4‑in‑1 adapter, especially when you work across iOS, Android and PC platforms. You may prefer a higher‑speed or more rugged reader if you routinely move large 4K video files or work in demanding field conditions.
