Needless to say, fast charging will ease the anxiety you get when you’re about to head out the door and realize your phone is at 17%. This means you can finally say goodbye to waiting around for your phone to charge and bid farewell to overnight charging entirely. If you’re wondering how much faster fast charging is, Apple claims it will refill up to 50% of your iPhone’s battery in a mere 30 minutes. But getting those kinds of speeds requires an even better charger.
The iPhone 8 and newer devices are capable of even faster charging with support for 18W connections and beyond. Most iPads come with a 12W charging block instead, so if you own an iPad, you can use one of these to speed up your iPhone’s charging rate - it won’t harm your phone in any way since the phone will never take more charge than it can handle. It can supply enough power for a basic overnight recharge, but it’s not able to transmit a charge fast enough to juice anything with a higher-capacity battery, like an iPad. You see, the 5W charger that came with most iPhones is not capable of fast charging. By upgrading to a USB PD connection, you can achieve charging speeds far faster than Apple’s older Lightning cable connections. It’s a very flexible and efficient option that can optimize power management. This technology is only available in USB-C connections, which can route power as well as data and are suitable for charging a variety of devices. Fast charging uses a newer USB technology called USB Power Delivery (USB PD). We’ve written a comprehensive guide to fast charging, but let’s review. What is fast charging, and why can’t my charger do it?
In this guide, we’ll walk you through how to do it, from determining whether your phone has the capacity for fast charging to the equipment that will cut down your charge time.
