Apple iPhone 15 series devices are some of the best smartphones in the business. However, they do not ship with chargers in the box. So if you’re in the market for an adapter to charge your new iPhone, you should consider opting for the best fast chargers for the iPhone 15 series from the list below.

Are you looking for a high-wattage fast charger that can top up two devices simultaneously? The UGREEN adapter fits the bill perfectly. The UGREEN fast charger supports a maximum output wattage of 45W.
As such, you can either only charge your iPhone or utilize the second USB-C port on the adapter to charge another device like the Apple Watch. With two devices interfaced to the adapter, your iPhone will get 25W, and the remaining 20W will be allocated for the other gadget. Apart from this, the UGREEN adapter comes with foldable prongs for added ease of use.
What We Like
- Compact form factor
- 45W output with dual ports
What We Don’t Like
- Power drops to 25W via one port when using both USB-C ports
Spigen GaN III 652

The Spigen 652’s design is similar to that of the UGREEN Nexode. However, for a slightly larger footprint, you get faster charging speeds—even when two devices are being charged simultaneously.
When using a single port, the adapter can output at 65W, which can charge a medium-sized laptop. The good part is even when using both ports, the power gets split into 40W and 25W. This way, even if you connect your iPhone, you can continue to charge the laptop as well.
What We Like
- High power output in a compact form factor
- 40W output even when charging two devices
What We Don’t Like
- N/A
Apple Dual USB-C Power Adapter

If you’re looking for a first-party MFI-certified accessory, you can’t go wrong with Apple’s in-house, dual USB-C charger. To that end, the unit can fast-charge the latest iPhone 15 series at maximum-rated speeds.
However, despite having a lower total output rating compared to the UGREEN and Spigen options, Apple’s contender is costlier. Along with a lower power output of 35W, the Apple adapter is also slightly larger, so it occupies more space on a power strip.
What We Like
- Foldable prongs
- Two USB-C ports
What We Don’t Like
- Pricey
Anker Prime USB-C Charger
- Output power : 67W
- Ports : 2 x USB-C, 1 x USB-A

Anker’s GaN Prime charger is largely similar to the Spigen 652. It’s compact, has foldable prongs, and outputs at a similar wattage—67W. The only difference is that Anker’s offering comes with an additional USB-A port.
When using a single port, the charger can output at 67W. However, if you use two or three ports, 65W will be split among all of them. So if you’re charging a laptop, you can still charge your iPhone 15 quickly at 20W.
What We Like
- Triple ports
- Compact form factor
What We Don’t Like
- Not great value for money

Most adapters on this list have a generic design. But if you want something that stands out and gives you a kick of nostalgia, the Shargeek Retro charger is a great option. We say this, as the charger outputs 67W of power and looks like Apple’s first Mac desktop.
The monitor displays the charging speed in real-time so you can see how fast your iPhone is charging. Thanks to 67W of power, you can charge larger devices like MacBooks and other laptops too. Even when two or even three devices are connected to the Shargeek Retro charger, the primary port outputs at 45W, thereby ensuring your iPhone 15 can charge at the best possible speed.
What We Like
- Cool design
- Built-in display
What We Don’t Like

Anker PowerCore 2-in-1 Hybrid Charger

- Ports : 2 x USB-C, 1 x USB-A

Anker PowerCore 2-in-1 Hybrid Charger

While all the other adapters on this list are compact, the Anker PowerCore is quite bulky. The reason is the Anker PowerCore isn’t your run-of-the-mill charger. Instead, it’s a wall adapter that also has a built-in power bank!
Thanks to this, it’s an ideal accessory for frequent travelers. Not only does the charger top up your iPhone, but it also charges the built-in 10,000mAh power bank simultaneously when plugged into a wall outlet. As for the charging capabilities, the adapter can charge the connected devices at up to 65W. However, you only get 30W of power when using the Anker PowerCore as a power bank.
What We Like
- Can turn into a power bank
- Multiple ports
What We Don’t Like
- Slightly bulky as a power adapter
All the iPhone 15 and 15 Pro models support 20W fast charging.
Yes, you can certainly use your old iPhone charger. However, ensure the adapter has a power rating of at least 20W to get the maximum speeds.
Fast charging is completely safe and can be of great help in a lot of situations. If you charge your phone overnight or for a long duration, just ensure you enable the Adaptive Charging setting on your iPhone.
