    beware of firmware update

    • Written by Paul F from Charlottesville

    I used to love this device. I used it to connect a DAC - worked great. Today, I plugged this into an ipad mini 4 and I was prompted to do a firmware update for the device. Ok, go. There is a counter indicating percentage of update completed, but no success or failure messages. After the update, just plugging this adapter into an ipad mini 4 or or an iphone SE gives the error: "Cannot Use Device. USB2.0 Hub: The connected device requires too much power." This is with just the adapter plugged in - no accessories. Either the FW damaged my device or its now only compatible with the 12.9" ipad pro (which has a usb 3.0 port)

    Limited Functionality

    • Written by Peter W from Washington

    The $40 adapter will allow you to transfer photos from your camera into Photos, it's advertised function. It also allows me to connect a DAC for headphone listening.

    It will not allow a USB thumb drive to connect - even when the iPad is connected to the charger via the pass-through - stating that it "requires too much power".

    Lightning port doesn't work with Apple's Lightning Headphones

    • Written by Darius W from Newton

    The lightning port doesn't work with Apple's own lightning headphones. It gives an error "This accessory is not supported by this device." I have a keyboard (music keyboard) that uses the USB portion just fine, but I cannot use headphones with it at all on my iPhone 7 plus. Bluetooth headphones have a significant delay and do not work with the keyboard. I'm left with having to listen to it out loud. Part of the reason I got the adapter was so I could play the keyboard without disturbing others. Very disappointed. The USB portion works, the lightning portion does not.

    Its fast... for the first few images. Ports are too close! Terrible design

    • Written by RJ A from Seattle

    Great for use on the 12.9 ipad with actual usb 3 speeds but its usually only for the first 30 or so photos. I'm using a lexar 2933x XQD card along with the Lexar LRWXQDU-7000 XQD reader to transfer. The photos app reads the photos really fast so there's less wait to start transferring photos. Starting out the first 30 or so photos transfer at roughly 10 photos a second. Then it bottlenecks somewhere and transfer slows down to roughly 2-3 photos a second and then 15 or so seconds later starts to pick up again slowly getting faster but never reaches the top transfer speeds like when you started out. Sometimes found transferring photos with a slower SDXC card using the lightning to sd card reader was sometimes faster for doing a lot a photos because the transfer speed is constant.

    I also found that the ports are too close together and using many memory cards readers would block the lightning port used to power the adapter. Terrible design so sometimes you have to use some kind of extension or usb3 elbow adapter.

    Doesn't seem to work

    • Written by Maksym H from Hoppers Crossing

    Whether USB device connected together with power or on its own - shows error "USB 3 connection requires too much power". Just double checked compatibility and it does work with iPad Air. For someone who is used to apple products just working it is disappointing.

    Exactly What I Needed

    • Written by Edward Y from Murrieta

    I use the iPhone 6 Plus as my main music listening device containing high-res audio files (ALAC, FLAC, DSD) through a very nice DAC headphone amp using the Lightning digital out and good headphones. Once you experience this kind of audio quality it's almost impossible to go back to the headphone jack on the phone.

    But one problem was that I wasn't able to charge the phone and deplete the battery during the long listening sessions. That problem is now completely solved with this adapter. I can get the digital audio out through the USB jack into the DAC while charging the phone at the same time. This is especially useful during a long flight (which I make frequently) and/or drive.

    For high-res audio listeners this accessory is a must.

    Fantastic product

    • Written by Sathees Kumar B from Gateshead

    I have used lightning to USB camera adapter and have always felt that the phone cannot be charged simultaneously. This adapter fixes that problem. I use my iPhone 5 and 6 to connect to an external USB DAC to listen HD audio using my headphones. The adapter powers the DAC and charges the iPhone at the same time.

    As usual the cable works right out of the box and the build quality is superior.

    Only Works with Apple 12w Charger and Mains Power

    • Written by Stephen C from Tunbridge Wells

    I was hoping this would work with my iPad Pro using a hefty portable Power Banker (Anker or the like). But no, always get the 'too much power' error. I can only get this working via the 12w Apple Charger plugged into the mains, so somewhat defeats the object of a portable solution.

    I bought so I could download photos from my SD card reader but it always comes up with the "too much power is required" error. Now it is useless.

    Using the USB 3 camera adapter for midi input

    • Written by Charles E from Largo

    I have a casio px-350, I connected it to the adapter and plugged it in to my ipad pro 12.9. No problems, after a few seconds I had midi input and output to the px-350. For quick easy work this adapter is great, no need for a separate midi adapter beyond this gizmo.

    I've been waiting for this adapter for so long

    • Written by Dillon A from Cumberland

    Ever since I got my iPhone 6 Plus, I have been using the original Apple USB Camera Adapter to connect it to a USB keyboard. This new adapter fixes all the issues I had with the old adapter. With the old adapter, I couldn't use my Apple Aluminum USB keyboard with my device because it has a hub and uses too much power. With the new adapter, I can just plug in a Lighning cord and I can connect my Apple Aluminum USB keyboard with my device. Best of all, the brightness, volume, play, rewind, and fast forward keys all work. I can even connect a second USB keyboard to one of the USB ports on the side of the Apple keyboard and use both keyboards at the same time. The other complaint I had about the old adapter was that you couldn't use USB devices and charge your device at the same time. This adapter allows me to both power USB devices that use more power than my device can provide and charge my device at the same time. One thing to note though is that if you use a little iPhone cube charger, you may not be able to charge your device very quickly if you have a USB device plugged in that requires extra power. Your iOS device will also complain that a device uses too much power if the connected USB charger (like the iPhone charge which is only 5 watts) does not provide enough power to power the USB device you are trying to connect. I have both the 12 watt iPad charger and the small iPhone chargers, and I have never had any problems with power as long as I use the 12 watt iPad charger. I can use both power hungry USB devices and charge my iPhone 6 Plus at the same time with the iPad 12 watt charger connected. My guess is that this is why this USB camera adapter is said to be only compatible with iPads. iPads mostly come with the 12 watt or 10 watt charger, and people with iPads don't need to go out and buy it, and they are less likely to attempt to plug it into a little iPhone charger. If you have trouble with your iOS device complaining that you don't have enough power even with a USB power adapter connected, try an iPad charger or something that will give you more wattage. That way, you will have enough power to go around.

    Does not work

    • Written by Alexander T from la mesa

    Got this hoping to be able to connect my USB drive to my ipad, but the ipad still says that the devices needs too much power, even after i connect the lighting charger to the adapter... This is no different than the old adapter.. Just more expensive..

    Power pass-through limitations

    • Written by Adam B from Royal Oak

    Regarding the power pass-through, it works with lightning cables and the Apple micro USB to lightning adapter, but *NOT* the 30 pin to lightning adapter. Just a heads up.

    USB works as advertised.
