Factors to Look for when choosing Power Banks for iPhone

Picking the right power bank gets much simpler once you know what to look for. Here are the key things to consider before buying one for your iPhone:

Capacity

The capacity of the power bank determines how many times it can charge your iPhone. A 10,000 mAh power bank is usually enough for one or two full charges for daily use. If you're traveling frequently or need more charging power, you might want to opt for a larger capacity, like 20,000 mAh.

Wireless Charging Support

For iPhone models that support wireless charging (including the iPhone 17), it's important to choose a power bank that supports MagSafe or Qi2. The iPhone 17 supports up to 25W MagSafe wireless charging and 25W Qi2 wireless charging, so choosing a power bank that supports these standards ensures fast and stable wireless charging.

Size and Portability

Consider how portable the power bank is, especially if you're using it on the go. A slim, lightweight design might be more convenient for everyday carry, while larger power banks are better for extended trips or heavy usage. Keep in mind that the higher the capacity, the heavier and bulkier the power bank will be.

Dual Charging or Multiple Ports

If you plan to charge multiple devices simultaneously, look for a power bank with multiple charging ports. Some power banks have both wired and wireless outputs, allowing you to charge your iPhone and another device (such as a tablet or earbuds) at the same time.

Build Quality and Safety Features

Look for power banks from reputable brands that include safety features like overcharge protection, short-circuit protection, and temperature control. These features will help ensure the safety of both your device and the power bank, preventing overheating or potential damage.

Conclusion

In conclusion, choosing the best power bank for iPhone depends on your specific needs, whether it's fast charging, portability, or wireless capabilities like MagSafe. With so many options available, from compact models to high-capacity powerhouses, there's a perfect choice for every iPhone user. Keep these key factors in mind, and you'll find a power bank that ensures your device stays charged and ready to go, no matter where you are.

FAQs  

Which power bank is best for an iPhone?

A good power bank for an iPhone should support at least 20W USB-C Power Delivery to enable fast charging and have enough capacity to match your daily use—typically 10,000 mAh is a great balance of power and portability.

If you prefer a wired option, the Anker Nano Power Bank 10K (30W) is compact, fast, and includes a built-in cable. For MagSafe users, the Anker MagGo Power Bank 10K Slim delivers full 15W wireless charging via Qi2 and stays slim enough to use while holding your phone. For more power, the Anker Prime Power Bank 26K 300W is perfect for extended trips, offering 26,000mAh capacity and fast charging for multiple device.

Can you use any power bank for an iPhone?

Technically, yes—most power banks will charge an iPhone, but not all will do it efficiently or safely. For best results, choose one with USB-C Power Delivery and at least 20W output. For wireless charging, look for Qi2 support to get full 15W speeds. Avoid cheap, non-certified models—they often charge slowly or overheat. Reliable picks like the Anker Nano Power Bank 10K (30W) or Anker MagGo Power Bank 10K Slim are iPhone-ready and built for safe, fast charging on the go.

Does Apple have a power bank for iPhone?

Apple offered the MagSafe Battery Pack, a compact wireless power bank that magnetically attaches to compatible iPhones (12, 13, and 14 series). However, it was discontinued in 2023 following the release of the iPhone 15 series, which adopted USB-C charging. For alternatives, Anker makes a popular range of MagSafe-compatible power banks which offer similar convenience, often with higher capacity and at a lower price point.

What capacity do I need for one full iPhone charge?

To fully charge an iPhone once, you'll need a power bank with at least 5,000 mAh. Most recent iPhone models, from the iPhone 13 to the iPhone 17 Pro Max, have batteries in the around 3,200-5,000 mAh range, though some energy is lost during charging. A 5,000-6,000 mAh power bank should give you one full charge, while a 10,000 mAh bank can provide about two full charges.

Is a 20,000mAh power bank good for an iPhone?

Yes, a 20,000mAh power bank is excellent for an iPhone, especially if you need multiple charges throughout the day. With this capacity, you can fully charge your iPhone several times, making it a great choice for long trips or heavy usage. However, keep in mind that larger capacity power banks tend to be bulkier, so consider portability if you're planning to carry it daily.
