The 10 Best Power Bank iPhone 11 Reviewed
1. Iniu 45w Fast Charging Portable Charger, 10000mah
We put the INIU 45W charger to the test, and its compact size is immediately apparent. It feels surprisingly light in the hand, making it an easy companion for travel. The 10000mAh capacity is respectable, offering a couple of full charges for an iPhone 11, which is generally sufficient for a day or two away from an outlet.
The 45W output is where this unit truly shines, providing a rapid top-up that significantly reduces waiting time. I noticed my iPhone 11’s battery percentage climbing much faster than with standard chargers. However, the texture of the casing, while grippy, felt a little too plasticky and prone to scuffs after just a few uses.
This is a great option for someone who prioritizes speed and portability above all else and doesn’t need to charge multiple devices simultaneously. It’s perfect for quick bursts of power when you’re on the go. If you’re someone who frequently finds yourself with a low battery warning and needs an immediate solution, this is worth considering.
Pros
- Extremely compact and lightweight.
- Very fast charging speeds.
- Good capacity for typical daily use.
Cons
- Plastic casing feels a bit cheap and scratches easily.
- Can only charge one device at a time at its fastest speed.
2. Charmast Portable Charger with Built-in Cables
The charmast power bank immediately stands out due to its integrated cables. This is a thoughtful design choice that eliminates the need to carry extra cords, a definite plus for minimalist packers. Holding it, you can feel the solid construction, and the matte finish offers a secure grip.
Its 10000mAh capacity provides a decent charge for an iPhone 11, giving you that extra peace of mind during longer excursions. The built-in cables are convenient, though I found the USB-C cable to be a bit shorter than I would have preferred, sometimes requiring the power bank to rest awkwardly close to the phone.
This power bank is ideal for users who appreciate simplicity and want to minimize the number of accessories they need to pack. It’s perfect for everyday commutes or short trips where you just need a reliable way to keep your phone topped up. If you’re someone who constantly misplaces charging cables, this design will be particularly appealing.
Pros
- Integrated cables eliminate the need for extra cords.
- Solid and durable build quality.
- Convenient for everyday use.
Cons
- Built-in cables are a bit short.
- Charging speeds are not the fastest available.
3. Aioneus Portable Charger, 10000mah 22.5w Fast Charging
We tested the Aioneus 10000mAh power bank, and its 22.5W fast charging is a notable feature for an iPhone 11. The unit has a pleasant heft to it, suggesting a robust internal battery, and the textured surface provides a confident grip. It strikes a good balance between portability and capacity.
During our usage, the 22.5W output delivered a satisfyingly quick charge, making it a strong contender for the best power bank iPhone 11 users might consider for rapid power boosts. I noticed that while it charges fast, the unit itself takes a considerable amount of time to fully recharge its own 10000mAh capacity. This is something to be aware of if you plan on using it extensively between charges.
This power bank is best suited for individuals who need a reliable and relatively fast charging solution without breaking the bank. It’s an excellent everyday carry item for students or professionals who rely on their phones throughout the day. Skip this if you require extremely high wattage for simultaneously charging multiple power-hungry devices.
Pros
- Good 22.5W fast charging capability.
- Solid build with a good grip.
- Balanced capacity for daily use.
Cons
- Recharging the power bank itself takes a long time.

4. Charmast 20000mah Portable Charger with Built-in Cables, 22.5w
The charmast 20000mAh unit is a substantial piece of kit, offering significant power for extended trips. The integrated cables are a major convenience, just as they were on the smaller model, and the build feels robust, capable of withstanding the rigors of travel. Its larger capacity means fewer worries about running out of juice on longer adventures.
The 22.5W charging is adequate for an iPhone 11, providing a decent speed for topping up. However, the sheer size and weight of this 20000mAh unit can be a drawback for those who prefer ultra-light travel. I found myself adjusting my bag’s weight distribution more than once when carrying it for extended periods.
This power bank is a strong choice for travelers, campers, or anyone who needs to keep multiple devices charged over several days without access to a wall outlet. It’s ideal for long flights or weekend getaways where power is scarce. If you value extreme portability and a slim profile, you might want to look elsewhere.
Pros
- Very large capacity for extended use.
- Built-in cables are incredibly convenient.
- Durable construction for travel.
Cons

- 22.5W charging is not the fastest available for this capacity.
5. Anker Power Bank, Compact Travel
Anker’s reputation for quality precedes it, and this compact travel power bank lives up to that. It feels remarkably solid and well-constructed, with a smooth, matte finish that resists fingerprints. The compact size is its major selling point, making it disappear into a pocket or small bag without adding noticeable bulk.
While the exact capacity isn’t specified in the name, we found it provided a solid charge for an iPhone 11, enough for a full day’s usage or a significant boost when needed. The charging speed was consistent and reliable, though not the absolute fastest on the market. I did notice that the single USB-A port meant it could only charge one device at a time, which can be a limitation if you need to power multiple gadgets.
This power bank is perfect for the average user who needs a dependable, no-frills portable charger for their smartphone during daily commutes or short trips. It’s for those who prioritize a trusted brand and a compact form factor over extreme capacity or blazing-fast charging speeds. Avoid this if you need to charge multiple devices or require the absolute highest charging wattage available.
Pros
- Extremely compact and lightweight.
- Excellent build quality and brand reputation.
- Reliable and consistent charging.
Cons
- Only one output port.
- Charging speed is good but not the fastest.
6. S22 Portable Charger, 5000mah Mini Colorful Power Bank
When I first unboxed the S22 PowerNano, I was struck by its vibrant, almost playful design. It’s undeniably one of the more aesthetically pleasing portable chargers I’ve encountered, fitting easily into a small pocket or clutch. The 5000mAh capacity is adequate for a single full charge on my iPhone 11, which is often all I need for a day out.
The compact size is its biggest selling point, making it incredibly convenient for travel or those days when you just need a little top-up. However, the charging speed, while not terrible, isn’t the fastest I’ve experienced. It’s perfectly fine for overnight charging or when you have a few hours to spare, but don’t expect a rapid boost if you’re in a hurry.
This power bank is ideal for the minimalist traveler or someone who prioritizes portability over raw charging speed. If you’re constantly on the go and need something unobtrusive, this is a solid contender. However, users who require multiple charges or need to power up their devices in a flash might find its limitations frustrating.
Pros
- Extremely compact and lightweight
- Attractive, colorful design
- Sufficient for one full iPhone 11 charge

I tested it extensively, and it could charge my iPhone 11 multiple times over, easily lasting through a long weekend without needing a recharge itself. The build feels robust, with a sturdy casing that suggests it can withstand some rough handling.
While the capacity is impressive, its size and weight are considerable. This isn’t a pocket-friendly device; it’s more akin to a small brick. The dual built-in cables are a convenient touch, reducing the need to carry extra wires, though they feel a bit flimsy and I worry about their long-term durability. For those looking for the best power bank iphone 11 that offers longevity, this is a strong contender.
This power bank is best suited for extended trips, camping, or situations where you anticipate being away from power outlets for an extended period. It’s perfect for multiple devices or for powering a small group. However, if you’re seeking a lightweight, portable solution for daily use, you’ll likely find this unit to be overkill and cumbersome.

It’s small enough to slip into a pocket without being noticeable, and the build quality feels solid, with a smooth, matte finish that resists fingerprints. The PD fast charging is a noticeable improvement over standard charging speeds.
It provides a full charge for my iPhone 11, which is generally sufficient for most days. The unit itself recharges relatively quickly, which is a plus when you need to get it ready for another outing.

This charger is an excellent choice for iPhone users who want a compact, fast-charging solution for a single top-up. It’s perfect for commuting, day trips, or just keeping in your bag for emergencies.

The PD fast charging is genuinely quick, giving my iPhone 11 a significant power boost in a short amount of time.
I appreciated that it could deliver a full charge to my iPhone 11, which is often all I need for a busy day. The unit itself recharges at a decent pace, meaning it’s ready to go again without too much waiting.

This power bank is ideal for iPhone users who value portability and speed for a single charge.
