Lightning to USB Camera Adapter Female USB OTG Cable Adapter for Select iPhone,iPad Models Support Connect Camera, Card Reader, USB Flash Drive, MIDI Keyboard, White (White)

This worked great!! I had an obscure usb key I needed to connect to my iphone 12, and this did the trick

Handing work that I've digitized to clients that want it on their phones.. easy to teach them with this reliable device

Works for DAC connections for USB audio and also portable storage devices like flash drives. If you're trying to do either of those with your iPhone then it will work great

While it works for many USB flash drives, some larger and SSD based USB mass storage drives could not get enough power to turn on. Best luck I has was with Microcenter 32/64/128/256 USB drives formatted in APFS. Will NOT work with mechanical drives, period. And remember that Lightning is limited to USB 2.0 so wait for the flash drive to stop blinking or the files to show proper data size before you unplug the drive.

False advertising. This adapter does not support USB 3.0:iPadOS reports this adapter as an A1440 (Apple’s Lightning to USB 2.0 adapter) with no serial number. The product images and the box say this adapter is USB 3.0, but unfortunately that is false advertising. I tested throughput as well with a gigabit Ethernet adapter, which maxed out at just under 400 Mbps. USB 2.0 supports 480Mbps, so this makes sense for a 2.0 adapter. The Apple A1619 adapter by comparison delivers over 900Mpbs with all other variables the same, maxing out Gigabit Ethernet.To add to the false advertising, this adapter sports a USB 3.0 port including the requisite pins and even blue colored plastic, but the internals both report and function as USB 2.0.Coil whine:When this adapter is plugged into an iPad or iPhone it emits a quiet high pitched whine. The sound increases in volume when the adapter is placed under load.Charging reliability:On multiple occasions, my iPad refused to charge when using this adapter. Either no charge ding at all, or a brief charge and then disconnect. A wireless mouse receiver connected to this adapter did continue to work during these charge issues.Output power:Both this adapter and the Apple A1619 deliver ~0.15A at ~4.80V when unpowered; this adapter provides the same output power and the A1619 provides closer to 0.5A when both adapters are powered. While this is enough to run many low power USB 2.0 devices like wireless receivers and flash drives when unpowered, it’s not enough current for USB 3.0. The USB 3.0 Ethernet adapter and flash drive used for testing both functioned out of this adapter with no Lightning power connector attached. But when connected to Apple’s true USB 3.0 adapter, they attempted to pull more current than available reporting “this accessory requires too much power” causing power to cycle to the device. This is resolved when external power is connected to the adapter’s Lightning port.A connected Seagate 2.5” USB 3.0 external HDD pulses the spindle motor on and off when this adapter is both powered and unpowered. The Apple A1619 adapter doesn’t send any power (according to my inline meter) to the HDD when unpowered, but once a lightning cable is attached provides 0.37A at 4.83V, enough to spin up the drive and access data in the Files app, though freezing and performance issues while copying data leads me to believe this is not quite enough power for my particular drive to perform reliably without a powered USB hub.Conclusion:If you’re looking for a USB 2.0 adapter that includes pass-through charging, Apple doesn’t offer one, so this adapter is interesting. I would rate this 3 stars based on features and price, considering 5 stars if the electrical noise and charging issues were resolved.I can’t recommend it at all however due to outright lies about the USB protocol version support both on this listing’s pictures and on the product box I received, including a USB 3.0 port to further confuse unsuspecting customers who may believe that a blue port is proof of what was advertised. They asked me in this review form to rate the product on “warmth” and “sheerness” as well, which I’ve done with a single star. What are these rating metrics? Unknown.The noticeable coil whine and charging irregularities cause me to doubt the safety and quality of this adapter’s internals; not only from the perspective of this adapter’s own longevity, but the safety of the expensive devices I would intend to connect to both sides of this adapter.For myself, I’m returning this item and keeping the Apple A1619.Tested with iPhone 8 and iPad Pro 10.5 running iOS/iPadOS 14.2

I ordered this Lightning to USB adapter to connect my Fifine AM8 microphone to my iPhone XR, and it worked exactly as advertised. The adapter is compatible with my old device and was super easy and hassle-free to set up. I also like that it’s a quality adapter, well-made with a durable-looking cable.

Great price and worked just as well as the name brand apple product!

This adapter is easy to use and transfers my photos and documents from my iPhone and iPad to my flash drives with ease. My questions how to best use this and make sure it’s right for my devices are verified on the Amazon description page and I received my order in quickly. I highly recommend this product.
