Top Power Bank Picks for iPhone in 2025

Keeping your iPhone alive all day shouldn’t mean lugging around a brick. Below are some of the best Apple power banks in 2025, covering every charging style. From ultra-slim MagSafe snaps to a fully-loaded Apple Watch hub, let’s see what each has to offer:

Anker Nano Power Bank 10K, 30W

Small enough to disappear in a jeans pocket yet punchy enough to top up a MacBook Air in a pinch, the 10,000 mAh Anker Nano Power Bank 30W is the “no-cable? no-problem” answer for USB-C iPhone owners.

Its built-in USB-C cable handles both 30W PD input and output, meaning you can refill the bank itself to 50% in about 45 minutes, then spin around and blast your iPhone 15/16 to 50% in roughly half an hour, all from the same tether.

A colour status screen shows remaining juice at a glance, while the USB-A port and a second USB-C port cover your AirPods or a friend’s lead without fuss. Dimensions stay travel-friendly at just 4.09 × 2.06 × 1.02 in and 215 g.

• Just over 200 g, so it rides comfortably in a jacket or handbag.

Anker MagGo Power Bank 10K, Slim

If you’d rather ditch cables completely, the Anker MagGo Power Bank 10K, Slim snaps to any MagSafe iPhone and feeds it a full 15W Qi2-certified wireless charge—fast enough to push an iPhone 15 Pro to 50% in under 45 minutes.

When time really matters, flip to the USB-C port for up to 30W wired output. At just 14.7 mm thick and 200 g, it slides into skinny jeans yet still squeezes in a 10,000 mAh pack for roughly 1.8 iPhone re-charges.

With its matte UV finish and sturdy metal frame, it feels sleek and premium. Plus, ActiveShield thermal tech keeps the surface temperature below 40°C even during intense use—making it arguably the best Apple wireless power bank you can get right now.

Anker 622 Magnetic Battery

The 9N magnetic array grips firmly through MagSafe cases, while a single USB-C port lets you pass-through charge or juice non-MagSafe kit. Weight lands around 140 g, and the fold-flat stand keeps bulk down when it’s in your pocket. Expect roughly one extra iPhone charge—perfect insurance when you head out for the evening.

Anker MagGo Power Bank 10K, 35W, for Apple Watch

For Apple fans who carry everything, this Anker MagGo Power Bank 35W is the Swiss-army knife. A pop-out, Apple-certified Apple Watch puck delivers 5W fast-charge while the built-in USB-C cable or port pushes up to 30W each—35W in total—enough to run an iPhone 15 Pro and Watch together.

A bright LED read-out tracks battery and live wattage, and the 10,000 mAh pack recharges at 30W in less than 2 hours. Made from 75% recycled plastic, it’s cabin-friendly, compact (95 × 51 × 32 mm), and lightweight at just 245 grams.

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 in mAh and Wh

Start with capacity, often listed in mAh (milliamp-hours):

• 5,000 mAhgives roughly one full iPhone charge
• 10,000 mAhgives about two
• And 20,000 mAh+is great for travel but comes with more bulk and longer recharge times

If you’re flying, it’s also worth checking the Wh (watt-hours). Airlines usually limit carry-on batteries to under 100 Wh, which is roughly 27,000 mAh for most power banks.

Charging speed & protocols

Next, check how fast it can charge your iPhone. Look for power banks that support USB-C Power Delivery (PD) with at least 20W output—this gets you that familiar “50% in 30 minutes” charge on newer iPhones. Some Pro models can pull even more, up to 27–30W, so extra headroom doesn’t hurt.

Fancy wireless? Look for Qi2

If you’ve got an iPhone 12 or newer, getting a MagSafe-compatible wireless battery pack is totally worth it. You just snap it onto the back of your phone—no cables, no hassle—and you’re good to go.

But here’s the catch: you’ll need to decide between Qi and Qi2. Qi2 is the newer, open standard developed with Apple’s help, and it gives you the same 15W fast magnetic charging as MagSafe.

A lot of cheaper options use regular Qi with compatible magnets, but those top out at 7.5W, so they charge more slowly and less efficiently. So, if you want true snap-on speed, make sure it says Qi2-certified.

Ports, Cables & Convenience

New electronics are now required to use USB-C, so most modern power banks include at least one. If you often charge multiple devices, look for models with two or three USB-C ports. It’s also handy to have at least one USB-A port for older gadgets.

Built-in USB-C or Lightning cables can be a lifesaver—no digging around your bag for a lead. If the built-in USB-C supports both input and output, you can use the same cable to charge the bank and your iPhone.

Pass-through charging is another bonus. That means you can charge the bank and your phone at the same time. Just make sure the device is well-designed with proper heat protection.

Size, Weight & Everyday Use

Think about how you’ll actually carry it.

• Slim 5,000–10,000 mAh banks under 250 g are perfect for pockets and daily commutes
• Larger 20,000 mAh options are heavier and better for backpacks, travel, or long days out

If you want something to use while your phone’s in your hand, go slimmer—even if it means sacrificing a little capacity.

Safety and certification

Finally, don’t overlook safety. Look for power banks with certifications like CE, UKCA, UL, or TÜV, which show that the device passed safety testing for overcharging, short circuits, and drops.

Tips to Maximise the Life of Power Banks

Even the best power banks wear out over time, but a few smart habits can keep yours going strong for years. Here’s how to get the most out of it:

Charge in the sweet spot

Lithium batteries don’t like being run completely flat or kept at 100% for too long. For longer battery health, try to keep your power bank between 20% and 80% most of the time. Once it’s fully charged, unplug it from the wall.

Keep it cool

Batteries last longest at room temperature. Heat speeds up ageing, and cold slows performance. Try not to charge it under a pillow, in direct sunlight, or in very cold environments. Ideally, store it somewhere cool and dry.

Use quality chargers and cables

Stick with PD-rated chargers and certified cables. Proper handshakes deliver only the amperage your battery pack requests, reducing stress on internal cells.

Limit pass-through charging

Pass-through charging (charging the power bank and your phone at the same time) is fine now and then, but doing it daily will generate extra heat and stress the internal cells. Reserve it for travel layovers or hotel nights.

Store It Smart

If you’re not using your power bank for a while, store it half-charged in a cool, dry spot. Avoid moisture and high heat, and check on it every few months with a quick top-up. Lithium batteries don’t like being ignored for too long.

Conclusion

Choosing the right power bank for i Phone doesn’t have to be complicated. Once you know what to look for—like the right mAh, solid 30W charging speed, and snap-on MagSafe convenience—it’s easy to find one that suits your lifestyle. And with a bit of care, your power bank will last for years, saving you hassle (and battery stress) on the go. Hopefully, this guide’s helped you cut through the noise. Ready to stay charged, wherever life takes you?

FAQs

Which power bank is good 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.

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—like the Anker 622 and MagGo—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 16 Pro Max—have batteries in the 3,200–4,700 mAh range, but some energy is lost during charging. A 5,000~6,000 mAh bank gives you one full charge, while a 10,000 mAh bank can deliver about two full charges.
