Making external storage work on iPhones with iOS 13

- or, why do I get "too much power" error with my drive and how do I fix it? -

Apple's official Lightning to USB Camera Adapter

With iOS 13, native support of USB external storage was introduced to iPhones. Files stored externally can be accessed from the Files app included in the OS. Other apps can do it as well if it can connect to this Files app. Sadly, modern iPhones' external port of choice is Lightning, which means you either buy a storage device with a Lightning port or get an adapter to connect a USB device. This is where things get complicated.

I bought a Lexar MicroSD to Lightning Reader (part # LRWMLBNL) more than three years ago. It connects directly to the Lightning port and I can open files using a dedicated app. Apple MFI certified storage can supposedly work with the iOS 13's Files app, but that wasn't the case here despite the certification. Adding insult to injury, its app had not been updated in more than two years - the screen resolution and the file sharing functions were outdated. I needed a different solution.

Apple sells many types of USB adapters, one of which is the Lightning to USB Camera Adapter you see above (US$29). It can be connected to a camera for transferring photos and videos, hence the name. Other devices could be plugged in as long as the OS recognizes it, like keyboard, MIDI equipment, or Ethernet adapter. iOS 13 expands this to general storage and mouse.

Plugging in a USB flash drive directly do the adapter results in a "Cannot Use Accessory: This accessory requires too much power" error

So I bought this adapter expecting that any low-power storage devices like USB flash drives and memory card reader could be plugged in directly for my file management uses. Boy was I so wrong. Of the multitudes of flash drives and card readers I own, all of them, save for one, caused the "too much power" error you see here. This was bizarre because they shouldn't consume enough power for this to appear. There had to be a reason and a way around this, so I decided to dig in.

This summer's lightning strikes at Bitgaram City

Bolt of lightning strikes the south of Naju Bitgaram City

This summer is proving to be particularly lightning-prone around this area. About two weeks ago (July 14), a lightning strike set fire to an empty house near my home. This afternoon, between around 17:10 and 17:25, lightning was striking left and right every few seconds. The two photos you see here were taken at 17:18. As a result, the internet connection at my apartment complex was down for about an hour and a half (and subsequently this website was not accessible at the time), and a small village near the city experienced a power outage.

And another strike next to it, a few seconds apart

Just as the lightning started to subside, we were met with heavy downpour for about 15 minutes. The rain eventually subsided about half an hour later, but not before filling the then-empty company pond and creating pockets of water on the road around the city. What a strange weather to be had for the last day of July.

Dealing with iPhone 7's missing headphone jack

The Lightning to 3.5mm headphone jack adapter bundled with iPhone 7

Given that iPhone's predecessor is iPod the digital music player, the listening experience is still a big part of the device for many people. So the removal of the 3.5mm headphone jack was bound to be controversial, despite the fact that Apple has provided many options to mitigate the inconvenience.

Primarily, the EarPod earphones bundled with iPhone 7 use Lightning connector, giving you at least one native solution. Along with that is a Lightning to 3.5mm headphone jack adapter that you can use with any other regular earphones and headphones. Because Lightning port is fully digital, the both the adapter and the earphones have DAC modules inside to provide analog audio output. Unless you must charge the phone at the same time, you're not worse off than before as long as the adapter works as intended.

On a side note, providing both a DAC-equipped earphone and an adapter resulted in sacrificing the plastic case for the earphones, likely because of costs. The case is now simply a throwaway paper packaging.
