Yes, You Do Need Apple’s USB-C to Lightning Cable to Fast Charge an iPad Pro

It was my birthday recently and I asked for one of the most exciting presents that an iPad geek could request: a $49 29-Watt charger. Riveting, I know! When I work with the iPad Pro at my desk for extended sessions, the 12W charger can barely keep up with the iPad as I use it, which means that when I’m low on battery, I just stay low on battery. Laptop and smartphone chargers usually outpace me and provide energy faster than I can use it up, but that hasn’t been the case with the iPad Pro.

This $49 charger was actually designed for the 12-inch MacBook, but Apple also released a USB-C to Lightning cable earlier this year, which allows the 29W charger to work its magic on the larger iPad Pro. Based on Federico Viticci’s intensive fast-charge testing of the iPad Pro, this combo of 29W charger and USB-C to Lightning cable are supposed to cut charging times in half.

However, in an attempt to save a bit of money, I first tried using Apple’s USB-C to USB adapter, which is meant for making the USB-C port on the MacBook available to standard USB accessories. I was hoping that this charger would be smart enough to let an attached Lightning cable send more electricity to my iPad Pro, while still allowing me the flexibility of using my existing set of Lightning cables.

I took two days to test the USB-C to USB adapter and found that it made no difference to charging speed, despite being used with the 29W charger. The staff at the Apple Store weren’t sure about this, but now I am. There might be an inhibitor in the adapter itself that keeps too much electricity from flowing through, or there might be something special about the actual USB-C to Lightning cable that Apple released earlier this year. Either way, in order to take full advantage of fast charging, you really will need to buy the 29W charger and Apple’s 1 m USB-C to Lightning cable, or the more expensive 2 metre version.

I opted for the 2 m version just because I’ll want this able for scenarios where I’m using the iPad Pro just like I would a laptop. I’m sitting and working for a long period of time, and I want the battery to be at 100% when I’m done.

In my tests thus far, it’s taken me about 2 hours to go from 14% to 93%; and that’s while writing on this iPad, uploading 400 pics to Lightroom in Split View, and watching a video in PiP mode for about 20 minutes. I would barely have charged at all if this were the standard 12W charger, and that’s pretty sad.

So on the one hand, I’m pretty happy to have finally bitten the bullet and gotten this 29W + cable combo for fast charging. However, I’ll also admit that Apple has once again suckered me into paying *far* too much for such a basic accessory. Luckily, I’ve been having a really good time working, reading, and surfing on the iPad Pro over the past few months, and so this does feel like a worthwhile investment for my own enjoyment.
