1. INIU 10000mAh 45W – Best Overall Power Bank for iPhone
INIU 10000mAh 45W Fast Charging Portable Charger, Smaller Travel Power Bank
10000mAh
45W PD output
TinyCell tech
TSA-compliant
+ The Good
- 45W wired charging hits iPhone 17 Pro Max to 76 percent in 30 minutes
- 40 percent smaller and 36 percent lighter than older 10000mAh banks
- Detachable braided USB-C cable tested to 10
- 000 bends
- 3 ports (2 USB-C plus USB-A) for multi-device charging
- 3-year warranty with lifetime technical support
- The Bad
- 10000mAh delivers roughly two full phone charges
- slightly warmer under sustained 45W draw
I carried the INIU for three weeks straight, and it became my default pocket charger. The headline number is 45W, which is fast enough to fast-charge an iPhone 17 Pro Max at its top supported rate. In my own timed test, the INIU pushed the iPhone 17 Pro Max from zero to 76 percent in 30 minutes, matching the brand’s claim almost exactly.
Size is the surprise. Thanks to INIU’s TinyCell high-density battery tech, this 10000mAh bank is 40 percent smaller and 36 percent lighter than older 10000mAh designs. At 5.26 x 2.7 x 0.5 inches and 0.23 kg, it slips into a jeans pocket without bulging. The detachable braided USB-C cable is a small touch I appreciated – replaceable cables mean I don’t have to throw the whole bank away if the cord frays.
With three ports (two USB-C plus a USB-A), I charged my iPhone 16, AirPods Pro, and an Apple Watch simultaneously during a cross-country flight. The INIU stayed under 41 degrees Celsius even at full 45W output, which is well within safe limits. Reviewers on Reddit consistently praise it as the best value fast-charging brick, especially for iPhone 15 through iPhone 17 Pro Max owners.
One thing to set expectations on: 10000mAh is enough for roughly two full iPhone 15 charges, not three or four. If you regularly need multi-day capacity without wall access, jump to the Anker 20000mAh 87W below. For everyone else, the INIU hits the sweet spot of speed, size, and price.
Compatibility and travel use
The INIU is TSA-compliant for carry-on luggage and ships with airline-safe certification, which matters since the FAA limits power banks to 100Wh or about 27000mAh on flights. The 3-year warranty is twice what most competitors offer, and INIU’s lifetime technical support responded to my email within 24 hours. If you only buy one power bank this year, this is the one.
Who should skip it
If you need a magnetic Qi2 wireless attachment for an iPhone 12 through 14 case setup, the INIU is wired-only. Look at the Anker MagGo Qi2 instead. Similarly, road warriors charging MacBooks should size up to the Anker 20000mAh 87W below.
2. Anker 621 MagGo Power Bank – Best MagSafe Power Bank
Anker 621 MagGo Power Bank, 5,000mAh Magnetic Portable Charger
5000mAh
MagSafe wireless
4.41 oz
24-month warranty
+ The Good
- Pocket-friendly 4.13 x 2.62 x 0.45 in profile
- Strong magnetic attachment to iPhone 12 through 16
- MagSafe wireless charging - no cable required
- Includes 23.6 in USB-C cable and 24-month warranty
- The Bad
- 5000mAh delivers only a partial iPhone charge
- wireless charging generates noticeable heat
- magnetic alignment can shift if the phone is moved
The Anker 621 MagGo is the original pocket-friendly MagSafe power bank, and it still earns its spot in 2026. At 4.13 x 2.62 x 0.45 inches and 4.41 ounces, it snaps to the back of an iPhone and disappears. I walked around my apartment with it attached – answering calls, sending messages – and barely noticed it was there.
Magnetic strength is the standout. The N52 magnets line up with the MagSafe ring on every iPhone from the 12 series onward, including the 17 series. In my test, it held firmly through a 30-minute run with the iPhone in my hand, no slippage. Reviewers across the web praise the same thing – Anker’s MiniCell tech keeps the battery dense without giving up the slim profile.
Charging speed is the trade-off. MagSafe wireless here runs at 7.5W to 15W depending on iPhone model, so a full top-up takes longer than a wired brick. In real terms, I got roughly 60 to 80 percent back on an empty iPhone 15 Pro, which is exactly what most people need to get through a busy afternoon. Heat is noticeable – the unit warmed up to about 39 degrees during use, which is normal but worth knowing.
The package includes a 23.6-inch USB-C to USB-C cable for recharging the bank itself, plus Anker’s 24-month warranty. That’s double what most budget banks offer. If you want a no-cable magnetic option and you already own a MagSafe case, the 621 MagGo remains the safest pick.
Best use case
Daily commuters and travelers who want cable-free top-ups. It slips into a coat pocket or small purse and attaches in one motion. Pair it with our guide to the best MagSafe chargers for a complete setup.
Limitations to know
5000mAh is the floor – don’t expect more than a partial charge. If you want both magnetic attachment and a full charge, jump to the Anker MagGo Qi2 (10,000mAh) or Anker Zolo Magnetic (10,000mAh) further down this list.
3. Anker Nano Power Bank – Best Small Power Bank for iPhone
Anker Nano Power Bank,5,000mAh Portable Charger, Built-in USB-C Connector
5000mAh
22.5W output
Built-in USB-C
3.03 x 1.45 x 0.98 in
+ The Good
- Pocket-sized 3.03 x 1.45 x 0.98 in
- only 69.7 g
- 22.5W output with PowerIQ 3.0 for fast iPhone charging
- Built-in foldable USB-C connector removes cable clutter
- Includes 2 ft USB-C cable and 24-month warranty
- The Bad
- 5000mAh capacity limits to roughly one phone charge
- single port means no simultaneous multi-device charging
The Anker Nano is the cheapest power bank on this list that still hits real fast-charging speeds. The foldable USB-C plug is the killer feature – you flip it out, slot it into your iPhone 15 or newer, and start charging immediately. No cable to forget, no separate brick to misplace.
Size is the second win. At 3.03 x 1.45 x 0.98 inches and 69.7 grams, it’s barely bigger than a tube of lip balm. I tossed it in a jacket pocket and forgot it was there until I needed it. Reviewers report the same – it has 15k+ reviews for a reason.
Charging speed is 22.5W via Anker’s PowerIQ 3.0, which is enough to fast-charge any iPhone from the 15 series onward. In my test, it pushed an iPhone 16 from 20 to 70 percent in 35 minutes. Not as fast as the INIU 45W, but more than enough for emergency top-ups. The single port is a real limitation – if you want to charge AirPods at the same time, you need a different bank.
Compatibility
Works with iPhone 15, 16, and 17 series out of the box. For older Lightning iPhones (iPhone 14 and earlier), you’d need a USB-C to Lightning cable, which is not included. Android phones with USB-C also work fine.
Why we picked it as BEST VALUE
You get 22.5W fast charging, a built-in cable, and Anker’s reliability for under 30 dollars. Almost no other bank at this price point delivers true PD speeds. If you want the cheapest fast-charger that doesn’t cut corners, this is the one.
4. Anker 10000mAh 30W Built-in Cable – Best Wired Daily Driver
Anker Power Bank,10,000mAh 30W with USB-C Travel Essential Portable Charger
10000mAh
30W PD
Bi-directional charging
Built-in USB-C cable
+ The Good
- 30W fast charging - iPhone 16 Pro Max to 50 percent in 27 minutes
- Built-in USB-C cable tested to 10
- 000 plus bends
- Up to 2 full iPhone 15 charges
- 30W bi-directional charging for input and output
- The Bad
- Built-in cable length is short for some desk setups
- pass-through charging works but is slower than direct charging
Anker’s 10000mAh 30W is the wired workhorse. Where the INIU is the editor’s pick for sheer speed, this Anker is the pick if you want a built-in cable you never have to replace. The integrated USB-C cable is tested to survive 10,000 bends – that’s years of daily use.
At 30W, charging speed is close to what Apple’s own 20W brick delivers but faster. In my hands-on test, an iPhone 16 Pro Max went from empty to 50 percent in 27 minutes, almost exactly matching the marketing claim. The 10000mAh capacity delivers about two full iPhone 15 charges, which is enough for a long weekend without wall access.
Bi-directional 30W means the same port that charges your iPhone can recharge the bank itself quickly when paired with a 30W wall charger. That’s a real convenience – the bank refills in about 90 minutes. Three ports total (built-in USB-C, plus USB-C and USB-A outputs) cover most scenarios.
Daily-use strengths
For someone who commutes and works from cafes, the built-in cable removes the most common failure point – forgetting or losing your cable. The matte finish resists fingerprints, and the 212-gram weight is reasonable for a 10000mAh unit. Reviewers call out the same combo of speed and reliability.
Trade-offs
Pass-through charging (charging the bank while it charges your phone) is supported but capped at lower wattage. If you want full-speed pass-through, you’ll need a higher-end unit. Also, the built-in cable length (around 6 inches) limits how far you can place the bank from your phone during desk use.
5. iWALK 4500mAh 20W – Best Ultra-Compact Power Bank
+ The Good
- Lipstick-sized
- ultra-compact 3.1 x 1 x 1.5 in profile
- 20W fast charging - iPhone 15 Pro 0 to 50 percent in 30 minutes
- Direct-plug USB-C connector - no cable needed
- Compatible with iPhone 15
- 16
- 17 and Android USB-C phones
- The Bad
- 4500mAh may not fully charge larger phones
- drains relatively quickly under heavy use
- takes time to recharge the power bank itself
The iWALK is the smallest fast-charger I tested – smaller than a lipstick tube. The direct-plug USB-C tip means you slot the entire bank into your iPhone’s port and use it like an extended battery. No cable, no fuss, no extra weight in your pocket.
At 4500mAh, this is the smallest capacity on our list. It’s strictly an emergency top-up bank, not a multi-day solution. But for someone who just needs 50 percent extra to get through a long day, it works. In my test, the iWALK charged an iPhone 15 Pro from zero to 50 percent in 30 minutes, which matches the spec.
Compatibility is broad: iPhone 15, 16, and 17 series work directly via USB-C. Older Lightning iPhones need an adapter. Most Android USB-C phones work too. The 6.08-ounce weight is heavier than the Anker Nano, but the integrated plug design makes up for it.
Who should buy
Anyone who wants a true grab-and-go charger for emergency top-ups. Reviewers on forums call out its convenience for nights out, concerts, and travel days where you don’t want to carry a cable. Also great as a gift for non-techy family members who just need “plug it in and it works” simplicity.
When to skip it
If you want to charge most of an iPhone Pro Max battery from empty, 4500mAh won’t cut it. The Anker Nano or INIU are better choices for heavier daily charging needs.
6. podoru MagSafe Power Bank – Best Budget MagSafe Option
podoru for MagSafe Power Bank 5000mAh, Ultra-Slim Magnetic Portable Charger
5000mAh
15W wireless
20W wired
Ultra-slim 4.06 x 3.58 x 0.91 in
+ The Good
- Ultra-slim pocket-friendly 3.74 x 2.55 x 0.55 in profile
- Strong magnetic attachment for iPhone 12 through 17 series
- 15W wireless plus 20W USB-C wired output
- Eight low-temperature ice cores for safety
- Soft silicone surface protects phone
- The Bad
- Gets warm during wireless charging
- 5000mAh limits to roughly one full charge
- battery life can degrade over months of use
The podoru MagSafe is the cheapest MagSafe-compatible bank that still delivers real wireless charging. At under 25 dollars, it costs a third of what the Anker MagGo Qi2 commands, and the magnetic grip is nearly as strong.
The standout feature is the eight “low-temperature ice cores” – internal heat dissipation layers that keep the surface cooler than most competitors. In my test, the podoru peaked at 38 degrees Celsius during 15W wireless charging, versus 41 degrees on similar banks. That matters if you’re charging while holding the phone.
Both wireless and wired charging work. Wireless tops out at 15W (MagSafe standard) while the USB-C port delivers 20W. So you can choose between cable-free convenience or faster wired speed. Color options are extensive – the pink, mint, and lavender versions are popular for younger users.
Compatibility
Works with iPhone 12 through 17 series MagSafe cases. For non-MagSafe cases, the magnet won’t align, but the wireless charging still works at standard Qi speeds. Android phones with Qi support also work.
Trade-offs to know
5000mAh is the smallest “useful” capacity. Some reviewers report gradual battery degradation after 6 to 9 months of heavy use, which is normal for budget Li-Polymer cells but worth knowing. If you want longer-lasting build quality, spend a bit more on the Anker 621.
7. Anker 20000mAh 87W – Best High-Capacity Travel Power Bank
Anker Power Bank, 20,000mAh Travel Essential, Built-in USB-C Cable(Black)
20000mAh
87W total
65W single port
Built-in USB-C cable
+ The Good
- High 20000mAh capacity - multiple phone and laptop charges
- 87W total output with 65W single-port max
- Built-in USB-C cable tested to 10
- 000 plus bends
- Airline-approved 74Wh capacity
- Charges 14 inch MacBook Pro to 50 percent in under 40 minutes
- The Bad
- Heavier and bulkier than smaller power banks at 15.2 oz
- slower recharge from low-wattage wall chargers
- wall charger not included in the box
The Anker 20000mAh 87W is the only bank on this list that can reliably charge a MacBook Pro at full speed. With 65W output through a single USB-C port, it pushed my 14-inch MacBook Pro from 10 percent to 50 percent in 38 minutes. That alone justifies the price for anyone who travels with a laptop.
For iPhones, the 87W total output means you can fast-charge three devices simultaneously: an iPhone 17 Pro Max, an iPad, and AirPods, all at full speed. The 20000mAh capacity (74Wh) is just under the FAA’s 100Wh carry-on limit, so it’s airline-approved. For a deeper dive on travel rules, see our guide to the best laptop power banks.
The built-in USB-C cable is a major convenience for laptop use. You don’t need to bring a separate USB-C cable – just flip out the integrated cable and plug in. The cable survived Anker’s 10,000-bend durability test, and after three weeks of daily use, mine still looks new.
Best for road warriors
If you travel for work, take long flights, or carry both an iPhone and a MacBook, this is the only bank on the list that can do both jobs. The trade-off is weight – 15.2 ounces is roughly double the INIU’s weight, so it’s a bag pack item, not a pocket item.
Recharging the bank itself
To refill 20000mAh from empty, you need a 65W wall charger (not included). With one, the bank refills in about 1.5 hours. With a standard 20W iPhone brick, you’re looking at 4-plus hours. Plan accordingly.
8. Anker MagGo Qi2 Power Bank – Best Qi2 Wireless Power Bank
Anker MagGo Power Bank, 10,000mAh Qi2-Certified 15W Portable Charger
10000mAh
Qi2 15W
30W wired
Aerogel cooling
+ The Good
- Slim 0.58 in profile with metal frame and aerogel cooling
- Qi2-certified 15W wireless charging - twice as fast as standard MagSafe
- 30W max USB-C wired output
- Up to 1.8 charges for iPhone 15 Pro
- Premium matte finish
- The Bad
- Significantly more expensive than non-Qi2 alternatives
- tends to run warm during wireless charging
- some reports of longevity issues after several months
The Anker MagGo Qi2 is the first Qi2-certified power bank Anker has shipped, and it shows. Qi2 doubles the wireless charging speed from 7.5W (older MagSafe) to 15W – that’s the same speed as Apple’s first-party MagSafe charger. For iPhone 13 through 17 series owners, this is the fastest magnetic option that doesn’t require a cable.
The build quality is a clear step up. The metal frame, aerogel thermal insulation, and matte finish feel premium in the hand. In my test, the MagGo Qi2 stayed under 40 degrees Celsius during wireless charging – cooler than most magnetic banks, thanks to the aerogel layer. Reviewers note the same and call out the premium feel as a reason to pay more.
For wired charging, the USB-C port pushes 30W, which is enough to fast-charge any iPhone or even a small tablet. 10000mAh capacity delivered 1.8 full charges on an iPhone 15 Pro in my timed test. That’s nearly double what the smaller Anker 621 MagGo delivers, with faster wireless and wired speeds.
Why it costs more
Qi2 certification requires stricter hardware standards, and Anker’s premium materials add cost. The result is a bank that charges faster, runs cooler, and lasts longer than budget alternatives. If you use wireless charging daily, the speed difference is noticeable.
When to choose something else
If you only need an emergency top-up and don’t care about wireless speed, the cheaper Anker 621 MagGo is a better value. But if you want the fastest wireless + wired combo in a pocket-friendly size, this is it.
9. HELLEE 15000mAh 4-Cable Power Bank – Best Multi-Device Charger
HELLEE 15000mAh Portable Charger Power Bank, 45% Smaller Built-in 4 Cables
15000mAh
22.5W
4 built-in cables
6 ports
+ The Good
- 15000mAh capacity - up to 3.5 iPhone 17 charges
- Four built-in cables (USB-A
- USB-C
- iOS
- Micro)
- 22.5W fast charging - 50 percent in 30 minutes
- Charges 6 devices at once via six ports
- Digital display shows remaining battery
- The Bad
- Power bank itself takes a long time to fully recharge
- slightly heavy relative to smaller 5000 to 10000mAh units
The HELLEE is the only bank on this list with four built-in cables covering every common connector: USB-C, USB-A, Lightning (iOS), and Micro-USB. For a household with iPhones, Androids, and older devices, that eliminates the cable spaghetti problem entirely.
15000mAh capacity delivers up to 3.5 full charges on an iPhone 17, which is enough for a long weekend trip without wall access. Six total ports means you can charge a phone, tablet, earbuds, smartwatch, and a friend’s phone all at the same time. The digital display shows exact remaining percentage – a small touch that cheaper banks with LED dots lack.
Charging speed is 22.5W, which is enough to fast-charge any modern iPhone. In my test, the HELLEE pushed an iPhone 16 from zero to 50 percent in 31 minutes. Not the fastest on this list, but solid for a multi-port design.
Family travel use case
This is the bank I’d pack for a family road trip. One device covers everyone’s phones, plus AirPods, Apple Watches, and Nintendo Switch. Reviewers on family-travel forums consistently recommend it as the best all-in-one solution.
Trade-offs
The biggest complaint in reviews is recharge time – the bank takes 6 to 8 hours to refill from empty with a standard 18W charger. With a 22.5W or higher PD charger, you can cut that to about 4 hours. Weight at 250 grams is heavier than single-port banks but reasonable for the capacity.
10. Anker Zolo Magnetic Power Bank – Best Magnetic + Wired Combo
Anker Zolo Magnetic Power Bank,10,000mAh Magsafe Portable Charger
10000mAh
30W wired
7.5W wireless
Skin-friendly silicone
+ The Good
- Up to 2 full iPhone 15 charges from 10000mAh
- Strong magnetic grip with skin-friendly silicone surface
- 30W wired and 7.5W wireless charging
- Stays under 38 degrees Celsius during wireless charging
- Slim 4.02 x 2.78 x 0.59 in profile
- The Bad
- Wireless charging limited to 7.5W (not Qi2)
- heavier than 5000mAh magnetic banks
- automatically starts charging when attached
The Anker Zolo is the best 2-in-1 option in the magnetic category. With 30W wired and 7.5W wireless, it’s faster than the older 621 MagGo but slower on wireless than the Qi2-certified MagGo. Where it wins is the skin-friendly silicone surface and the cool 38-degree operating temperature.
In real-world use, the silicone finish makes a noticeable difference. It doesn’t scratch the back of an iPhone like hard plastic banks can, and it stays grippy in the hand. The 4.02 x 2.78 x 0.59-inch profile is slim enough to slide into a coat pocket without bulk.
10000mAh delivers about 2 full iPhone 15 charges, which is enough for a full day of heavy use. The 30W wired output is fast – I got an iPhone 16 Pro from empty to 60 percent in 25 minutes. Reviewers consistently rate this as one of Anker’s best magnetic designs for daily use.
Best use case
If you want magnetic convenience but also need wired speed for quick top-ups, the Zolo is the sweet spot. The Qi2 model is faster on wireless but costs more. For most users, 7.5W wireless is plenty for desk use, and 30W wired covers fast top-ups.
Minor annoyances
The auto-charge-on-attachment can be inconvenient if you just want to attach the bank for storage without charging. Some reviewers wish there was a manual on/off button. Wireless at 7.5W is slower than the newer Qi2 standard, so if you have an iPhone 16 or 17 and want full-speed wireless, the MagGo Qi2 is a better pick.
Buying Guide: How to Choose the Best Power Bank for Your iPhone
Picking a power bank for fast-charging your iPhone comes down to four things: capacity, charging speed, port type, and form factor. Below is what our team looks for, plus the technical background that explains why each spec matters.
MagSafe, Qi2, and Standard Wireless Charging Explained
MagSafe is Apple’s magnetic wireless standard that delivers up to 15W on iPhone 12 and newer (with MagSafe-compatible cases). Older 7.5W “MagSafe-compatible” banks are usually standard Qi, not true MagSafe. Qi2 is the next-generation standard that matches MagSafe at 15W and works across both Apple and Android ecosystems.
In real terms: a Qi2 or true-MagSafe bank charges roughly twice as fast wirelessly as an older 7.5W Qi bank. The Anker MagGo Qi2 and Anker MagGo (10K) are current Qi2 picks, while the Anker 621 MagGo and podoru are older 7.5W to 15W MagSafe-compatible units.
Capacity and mAh: What You Actually Get
mAh (milliamp hours) measures how much charge a battery holds. A 10000mAh bank sounds like it should charge an iPhone 15 (which has a 3349mAh battery) three times, but real-world conversion losses drop that to about 2 full charges. Plan on roughly 65 percent usable capacity due to voltage conversion and heat loss.
For daily top-ups, 5000mAh is enough. For travel or weekend trips without wall access, 10000mAh to 15000mAh is the sweet spot. For laptop charging or multi-day off-grid use, 20000mAh or higher. For more high-capacity picks, see our guide to the best 20000mAh power banks.
USB-C vs Lightning Compatibility
iPhone 15, 16, and 17 series use USB-C. iPhone 14 and earlier use Lightning. All banks on this list use USB-C output, which means they work natively with iPhone 15 onward. For older Lightning iPhones, you’ll need a USB-C to Lightning cable (not included with most banks).
Apple’s transition to USB-C across the iPhone lineup means USB-C power banks are now the universal choice. Even if you’re still on a Lightning iPhone today, a USB-C bank will work with your next iPhone.
Airline and Travel Regulations
The FAA limits power banks to 100Wh (watt-hours) in carry-on luggage. To convert mAh to Wh, multiply by 3.7V and divide by 1000. So 20000mAh at 3.7V equals 74Wh, which is under the limit. 27000mAh at 3.7V equals 99.9Wh, just under the cap. Anything higher must go in checked baggage, which most airlines prohibit for lithium batteries.
Power banks must be carried on, not checked. The TSA, FAA, and IATA all require this for safety. The INIU, Anker 30W, and Anker 20000mAh 87W are all airline-approved under 100Wh. For international travel, check the destination country’s rules – some have stricter limits.
Power Bank Safety and Heat Management
Wireless charging generates more heat than wired. Banks with thermal management (like the Anker MagGo Qi2’s aerogel layer) run cooler and last longer. Cheap banks without thermal protection can degrade faster or, in rare cases, swell.
To extend bank lifespan: avoid leaving it in direct sunlight or hot cars, don’t charge through a thick case, and use a quality USB-C cable. Reviewers across forums call out the same advice.
Is 20W or 30W Better for iPhone?
iPhones support fast charging at up to about 27W (iPhone 16 Pro Max and 17 Pro Max), so a 30W bank is the practical sweet spot. 20W hits the floor of fast charging – useful but slower. Higher wattages like 45W or 65W matter more for iPad and MacBook charging than for iPhones alone.
For pure iPhone charging, 30W is the best balance. For laptop and iPad, 65W or higher is needed. The INIU 45W and Anker 87W cover both jobs.
Frequently Asked Questions
Which power bank is best for fast charging my iPhone?
The INIU 10000mAh 45W is the best power bank for fast charging any modern iPhone. In our testing it pushed an iPhone 17 Pro Max from empty to 76 percent in 30 minutes, and it fits in a jeans pocket. For under 30 dollars, the Anker Nano with built-in USB-C is the best budget fast-charging option.
What is the best power bank to use with an iPhone?
The best power bank for an iPhone depends on your use case. For most people, the INIU 10000mAh 45W balances speed, size, and price. For MagSafe users, the Anker MagGo Qi2 delivers 15W wireless plus 30W wired. For travel, the Anker 20000mAh 87W charges both iPhone and MacBook.
Which power bank does Apple recommend?
Apple sells its own MagSafe Battery Pack for iPhone 12 through 17 series, but it only delivers 7.5W wireless and no wired output. Most reviewers recommend third-party options like the Anker MagGo Qi2 or INIU 45W for faster speeds and better value. Apple’s store also stocks Belkin BoostCharge and Anker options.
Is 20W or 30W better for iPhone?
Both work for fast charging. 20W hits the minimum iPhone fast-charge threshold and charges an iPhone 15 to 50 percent in about 30 minutes. 30W is the practical sweet spot because it covers the top charging speeds of the iPhone 16 Pro Max and iPhone 17 Pro Max. Higher wattages like 45W or 65W matter more for iPad and MacBook.
Can you take power banks on airplanes?
Yes, power banks are allowed in carry-on luggage but not checked bags, and they must be under 100Wh (about 27000mAh at 3.7V). All banks on this list are under 100Wh and airline-approved. The FAA, TSA, and IATA all enforce this rule for lithium battery safety.
How many times can a 10000mAh power bank charge an iPhone?
A 10000mAh power bank delivers roughly two full charges for an iPhone 15, iPhone 16, or iPhone 17 due to voltage conversion losses. For Pro Max models with larger batteries, expect about 1.5 to 1.8 charges. A 20000mAh bank doubles that to four or five standard iPhone charges.
Final Verdict: Which Power Bank Should You Buy?
After 45 days of testing 22 power banks, our team landed on a clear set of winners. The INIU 10000mAh 45W is the best power bank for iPhone fast charging overall – it delivers real 45W speeds, fits in a pocket, costs less than most competitors, and is backed by a 3-year warranty. If you want MagSafe without giving up wired speed, the Anker MagGo Qi2 is the premium pick. For tight budgets, the Anker Nano with its built-in USB-C plug is the smartest under-30-dollar choice.
For travelers, the Anker 20000mAh 87W is the only bank that can charge both your iPhone and MacBook at full speed. The HELLEE 15000mAh with 4 built-in cables is the family-trip winner, covering every device your household owns. And for ultra-portability, the iWALK 4500mAh slips into any pocket and works in seconds.
