Many current USB thumb drives exceed the power delivery capabilities of the iPad - and therefore require additional power to operate. This is a burnt-in value is retained within the USB accessory - and if this nominal “declared” value exceeds the power delivery capability of the iPad, then the iPad will display the warning message and not enable power.Ĭonsider also that whilst the iPad (often with the aid of an adapter) can now be connected to external USB accessories, it cannot provide the power capabilities of a traditional computer.
Why does apple show that a thumb drive without added power works fine and all mine refuse to turn on showing that “requires too much power” message?Īll USB devices, upon initial connection to a USB Controller, declare their power requirements (in mA) to the host device. This feature ***** if it can only be used with basic thumb drives and connected to power after spending 45€ on the adapter. The lightning cable connected provides and the hard drive requires 0,5A so it should work. I connect my hard drive WITH THE ADDED POWER OVER THE LIGHTNING PORT and the drive refuses to turn on and I cannot use it, even the “requires too much power” prompt does not show up, with or without adding power through the lightning port on the adapter. I’ve tried multiple and different models and same happens for all, only turning on with added power. Once I connect the lightning cable, the flash drive turns on and shows in the files app. Apple shows in the tips app the ability to access external drives as a new important feature of iPad OS and it advertises that thumb drives can be used without any additional power. Same occurs on my father’s 10.5 iPad Pro.
I bought the adapter (45 euros btw) and I’ve connected a simple basic usb 2.0 8gb Kingston Datatraveler G3, and it tells me it requires more power. It only shows the flash drive working on the iPad with no added power. In the tips app preinstalled on my 2018 6th gen iPad, they show me a lightning iPad with and external usb flash drive connected to the iPad using the lightning to usb3 camera adapter.
