Comparison Table: Best Fast Chargers for iPhone (2025)

Does Your iPhone Support Fast Charging?

iPhone have supported faster charging since the iPhone 6, which could charge at 12W using an iPad adapter. However, Apple introduced USB Power Delivery (PD) for faster charging starting with the iPhone 8 in 2017. This technology allows for significantly quicker charging speeds. The iPhone 8 and newer models, including the iPhone 15 and iPhone 16, officially support 20W fast charging for a 50% charge in around 30 minutes.

Since 2020, Apple no longer includes power adapters with new iPhones, meaning you'll need to purchase a compatible charger separately. While you can use an older charger, it may not deliver the faster charging speeds that newer models support, so it's worth investing in a PD-enabled charger from our list.

What You Need for Fast Charging Your iPhone

So, if your iPhone supports fast charging and you also have a fast charger, can you definitely fast charge your phone? Not quite—there's one more crucial component: a high-quality USB-C to Lightning or USB-C to USB-C cable. Apple's fast charging relies on USB Power Delivery (PD), meaning you'll need a PD-compatible cable to take full advantage of rapid charging speeds. If you have an iPhone 8 to iPhone 14, you'll need a USB-C to Lightning cable for fast charging. However, if you own an iPhone 15 or later, which features a USB-C port, you'll need a USB-C to USB-C cable for the best charging performance.

Additionally, using an MFi-certified (Made for iPhone) cable ensures optimal performance and safety. Non-certified cables might not support fast charging or could even damage your device over time. To get the best results, pair your speedy charger with an Anker USB-C to Lightning cable or Anker USB-C to USB-C cable, both designed to handle high-speed charging efficiently and safely. With the right charger and cable combination, you can power up your iPhone quickly and get back to what matters most.
