3 Power Banks for iPhone 11 Pro Max

These three power banks are ranked by charging fit and value, counting down to the top pick.

3. MagSafe Magnetic Wireless Power Bank

Best for: daily iPhone top-ups on the go

This slim magnetic power bank adds 5,000mAh without taking much room. It measures 0.55 inches, or 14mm, thick and weighs 128g, so it should fit a coin pocket, small bag, or evening clutch more easily than larger battery packs. The magnetic connection is designed for iPhone 12 through iPhone 17 models and uses 18 N52 magnets with up to 1,100g of holding force. It also works with MagSafe-compatible cases up to 3mm thick.

Charging options are flexible for the size. The wireless pad supports up to 15W, while the USB-C port provides up to 20W PD charging. The maker claims a wired charge from 0% to 60% in 30 minutes, and you can charge an iPhone wirelessly while powering AirPods through USB-C. Four LEDs show remaining battery level. Built-in safeguards cover overcharging, overheating, overcurrent, short circuits, and foreign objects. Around $14, plus a three-year replacement warranty, it offers useful value. Still, 5,000mAh is better for a daily boost than repeated full charges.

Pros

• 14mm thickness and 128g weight make it easy to carry.
• 15W wireless and 20W USB-C charging support flexible top-ups.
• 18 N52 magnets and 1,100g holding force help keep it attached.

Cons

• 5,000mAh provides limited capacity for larger phones or multi-day trips.
• Magnetic use depends on a compatible phone or case, and cases thicker than 3mm may not work well.

2. [2 Pack] Portable Charger Power Bank for iPhone

Best for: iPhone users needing backup power

This two-pack includes two compact plug-in chargers made for compatible iPhone models. Each unit measures 3.2 by 1.96 by 1 inch and weighs about 100 grams, roughly the size of a lipstick. The built-in connector means you do not need a separate charging cable for your phone. Both chargers support many models, from the iPhone 6s and SE through the iPhone 14 series. At around $29 for the pair, it offers a practical option for keeping one charger in a purse and another in a travel bag.

Each power bank has a 5000mAh battery rated at 3.7V. The listed capacity typically provides about 0.9 to 1.5 iPhone charges, so it works best as emergency backup rather than a full power solution. A 15W USB-C port supports input and output, with up to 3A charging speed for compatible devices. Pass-through charging lets the phone and battery charge together. The package includes two USB-C cables, one manual, and a 36-month warranty with customer support.

Pros

• Two chargers cover separate bags, rooms, or travel kits.
• Small 3.2-inch body fits pockets and compact purses.
• Pass-through charging and 15W USB-C support add flexibility.

Cons

• A 5000mAh unit may provide only 0.9 to 1.5 iPhone charges.
• Compatibility focuses on iPhones, so Android users should verify connector support before buying.

1. Portable Charger Power Bank, 2-Pack

Best for: iPhone users needing pocket backups

This two-pack includes two small plug-in power banks, one black and one blue. Each unit measures 3.2 by 1.96 by 1 inch and weighs about 100 grams, so it can fit in a pocket, clutch, or small purse. The built-in phone connector removes the need to carry a separate charging cable for compatible iPhones. Each 5000mAh battery provides roughly 0.9 to 1.5 charges, depending on the phone model and battery condition.

The 15W USB-C port supports input and output, allowing the power bank to recharge at up to 3A and charge other compatible devices. Pass-through charging lets you power an iPhone while the battery pack itself is plugged in. Internal controls help guard against overcharging, excess voltage, excessive current, and short circuits. The package includes two USB-C cables and one manual. Around $29, the set offers a practical backup for short trips, commutes, and outdoor use. A 36-month warranty and stated 24-hour customer support add useful coverage.

Pros

• Two 5000mAh chargers provide separate backups for home, travel, or family use.
• Compact 3.2-inch size and 100-gram weight make each unit easy to carry.

Cons

• Each battery may provide less than one full charge on some larger iPhone models.
• Compatibility centers on older Lightning-equipped iPhones, not newer USB-C iPhone models.

Buying Guide

Capacity is the most important factor because the iPhone 11 Pro Max has a 3,969 mAh battery. A 10,000 mAh charger usually provides about 1.5 to 2 full recharges after energy loss.

• Capacity: Choose 10,000 mAh for daily backup or 20,000 mAh for trips and several days away from outlets. A larger unit will weigh more.
• Charging speed: Look for at least 18W USB-C Power Delivery, which matches the phone’s fast-charging capability. Confirm that the package includes a USB-C cable if needed.
• Size and weight: A compact 10,000 mAh model often measures about 5.5 by 2.7 inches and weighs 6 to 8 ounces. A 20,000 mAh model can weigh 12 ounces or more.
• Ports: Pick a charger with one USB-C input/output and at least one USB-A port if you carry older cables. Two outputs help charge another device.
• Wireless charging: The iPhone 11 Pro Max supports Qi charging, but not built-in MagSafe alignment. Choose a Qi pad rated for iPhone charging, or use a cable for faster results.

If you cannot have everything, prioritize 18W USB-C Power Delivery and a 10,000 mAh capacity.

Frequently Asked Questions

How many mAh should a power bank have for an iPhone 11 Pro Max?

A 10,000mAh power bank offers the best balance for most iPhone 11 Pro Max owners, while a 20,000mAh model suits travel or repeated charging. Real output is lower than the printed capacity because of conversion loss. A 10,000mAh pack usually provides roughly one and a half to two full charges.

What should I look for in a portable charger for iPhone 11 Pro Max?

Look for at least 18W USB-C Power Delivery, a USB-C cable or compatible Lightning cable, and a capacity between 10,000mAh and 20,000mAh. The phone uses a Lightning port, not USB-C. A 20W PD battery can charge it quickly, but the right cable remains necessary for wired charging.

Can any power bank fast-charge an iPhone 11 Pro Max?

No, only a battery pack with USB-C Power Delivery and a suitable Lightning cable can provide the phone’s fastest wired charging. Choose an output of 18W or higher, though the iPhone controls the actual rate. Wireless models may charge more slowly, often around 7.5W with compatible Qi charging.

Are magnetic power banks compatible with the iPhone 11 Pro Max?

Yes, but magnetic power banks need a compatible case, ring, or alignment accessory because this model does not include MagSafe magnets. Qi wireless charging works through suitable cases. For reliable alignment, a regular wired pack with a Lightning cable is often simpler and can deliver charging at up to 18W.

Conclusion

Portable Charger Power Bank, 2-Pack, is the top pick for iPhone 11 Pro Max owners who want a spare charger for travel, work, or shared household use. If your priority is maximum capacity from one unit, pick a larger single power bank instead, since it can provide more charging cycles without carrying a second battery. Before buying, double-check the bank’s size, compatibility with your iPhone 11 Pro Max, included quantity, and current price because listings and bundles can change. This two-pack makes sense for keeping one battery at home and one in a bag, but it may take more room than a slim single charger. Check your connector needs, too.
