We tested 9 power banks across six months of real travel — long-haul flights, full-day sightseeing, multi-day hikes and city exploration. We measured actual capacity versus advertised capacity, real charging speeds, heat management and portability. This is the most thorough power bank comparison we have published.
Running out of battery while navigating an unfamiliar city, boarding a flight, or capturing a once-in-a-lifetime moment is one of the most preventable travel frustrations there is. A good power bank costs $25–$150 and eliminates this problem entirely — yet millions of travellers still leave home without one, or carry one that is underpowered for their actual needs.
The power bank market in 2026 is mature but confusing — exaggerated capacity claims, misleading speed specifications and wildly varying build quality make choosing the right one harder than it should be. We cut through the marketing noise with real-world testing data to give you honest recommendations at every budget and capacity level.

1. Anker 737 PowerCore 26K — Best Overall Travel Power Bank
The Anker 737 is the power bank we put in our bag for every trip without a second thought. Its 26,800mAh capacity is large enough to fully charge a MacBook Air twice over, or an iPhone 15 Pro approximately seven times. The headline feature is its 140W USB-C output — one of the highest available in a consumer power bank — which means it charges even high-performance laptops at full speed rather than the trickle rate of underpowered alternatives.
In practical travel testing, the Anker 737 proved its worth on a 14-hour London-to-Singapore flight where we charged a laptop from 10% to full, then charged a phone twice, and still had approximately 35% capacity remaining upon landing. For travellers who work on laptops during flights or between meetings, this level of capacity provides genuine all-day confidence.
The digital display showing percentage remaining (rather than the frustratingly vague LED dot system most power banks use) is a thoughtful feature — you always know exactly how much capacity remains rather than guessing. The dual USB-C and single USB-A ports allow simultaneous charging of three devices, which is practical for travellers carrying phone, tablet and earbuds.
The main trade-off is weight — at 655g, the Anker 737 is noticeable in a bag. But the capacity-to-weight ratio is excellent for what it delivers, and for travellers who regularly need to charge laptops away from sockets, the weight is justified by the utility.

Our verdict: The Anker 737 is the best travel power bank for anyone who needs to charge laptops on the go. The 140W output and 26,800mAh capacity are genuinely class-leading.
2. Anker 521 PowerCore 10,000mAh — Best Lightweight Travel Power Bank
For travellers who only need to charge their phone and earbuds — and who prioritise carrying as little weight as possible — the Anker 521 is the power bank we recommend. At just 230g and roughly the size of a thick credit card, it slips into any pocket or bag compartment and provides approximately three full iPhone charges from its 10,000mAh capacity.
The 30W USB-C output charges modern iPhones and Android phones at full fast-charge speed — dramatically faster than the 5W or 12W output of budget alternatives that take three or four hours to charge a phone. In real-world testing, the Anker 521 charged an iPhone 15 from 10% to 80% in approximately 45 minutes via USB-C.
The build quality is excellent for the price — the rubberised texture prevents it sliding off surfaces, the single LED indicator light accurately reflects remaining capacity, and the USB-C to USB-C cable included in the box is a thoughtful addition. At $26, the Anker 521 represents outstanding value for the single most practical travel power bank size.
Pros
- Ultralight at 230g
- 30W fast charging
- Pocket-sized convenience
- Excellent Anker build quality
- Outstanding value at $26
Cons
- Cannot charge laptops
- Only 3 phone charges from 10,000mAh
- Single USB-C port only
Our verdict: The Anker 521 is perfect for light travellers who only need phone charging. It is the power bank we carry as a secondary backup alongside the Anker 737.
3. Baseus Blade 100W — Best Slim Travel Power Bank
The Baseus Blade solves a genuine problem — most high-capacity power banks are thick and chunky, making them awkward to carry in slim bags or pockets. The Blade’s distinctive flat, card-shaped design is just 14.4mm thick despite packing 20,000mAh and a 100W USB-C output that charges laptops at near-full speed.
In our testing, the Baseus Blade slid neatly alongside a laptop in a sleeve with no extra bulk — a meaningful practical advantage for minimalist travellers who resent giving up bag space to thick, rounded power banks. The 100W output charged a MacBook Air from 20% to full in approximately 90 minutes — impressive for a power bank in this form factor.
The dual USB-C ports allow simultaneous laptop and phone charging. The intelligent power distribution adjusts output between ports automatically, prioritising the device that needs charging fastest. The build quality matches premium power banks at twice the price — the aluminium shell feels genuinely premium and provides good heat dissipation during high-power charging.
Pros
- Ultra-slim flat design
- 100W laptop charging capable
- 20,000mAh generous capacity
- Dual USB-C smart distribution
- Premium aluminium build
Cons
- No USB-A port
- Gets warm during 100W output
- Slightly slower self-charging
Our verdict: The Baseus Blade is the best power bank for travellers who need laptop charging capability in the slimmest possible package. The design is genuinely innovative.
4. Anker 633 MagGo — Best Power Bank for iPhone Users
For iPhone 12 or later users, the MagSafe ecosystem opens up wireless charging options that make traditional wired power banks feel antiquated. The Anker 633 MagGo snaps magnetically to the back of your iPhone — no cable, no port, no fumbling — and charges wirelessly at up to 7.5W while you use your phone normally. It is simultaneously a stand that holds your phone at a comfortable viewing angle.
The 10,000mAh capacity provides approximately two full iPhone charges wirelessly. A USB-C port allows simultaneous wired charging of a second device — or faster wired charging of your iPhone when speed matters more than wireless convenience. The magnetic attachment is secure enough to walk around with the power bank attached to your phone without any concern about it dropping.
Pros
- MagSafe wireless — no cable needed
- Built-in stand function
- Secure magnetic attachment
- USB-C backup wired port
- Neat, premium design
Cons
- iPhone 12+ only
- 7.5W wireless slower than wired
- Adds bulk to phone in use
Our verdict: For iPhone users who want the most convenient charging experience on the move, the Anker 633 MagGo is a genuinely delightful product. Just do not expect the speed of wired charging.
Airline power bank rules: All power banks must travel in carry-on baggage only — never in checked bags. Most airlines allow power banks up to 100Wh (roughly 27,000mAh at 3.7V). The Anker 737’s 26,800mAh equals approximately 99.16Wh — just within the 100Wh limit permitted by most carriers. Always check your specific airline’s policy, particularly for flights to or within the USA and Australia where regulations can differ.
How to Choose the Right Power Bank for Your Travel Style
For Phone-Only Travellers
A 10,000mAh power bank with 18W+ fast charging is everything you need. The Anker 521 at $26 delivers three phone charges at fast-charge speed in a device lighter than most water bottles. Do not pay more than this unless you genuinely need laptop charging capability.
For Laptop + Phone Travellers
You need at least 20,000mAh and a USB-C output of 60W minimum — 100W+ is ideal. The Baseus Blade and Anker 737 are both excellent choices. Budget for $70–$100 for a power bank that genuinely charges your laptop rather than just supplementing it slowly.
For Multi-Day Trips Without Reliable Power Access
The RAVPower 30,000mAh’s maximum capacity is unmatched for multi-day hiking, camping or travel in regions with unreliable electricity. At the maximum airline-permitted 100Wh limit, it provides the most stored energy legally permitted in carry-on baggage.
Capacity Claims vs Real-World Performance
Power bank capacity is advertised in mAh (milliamp hours) measured at 3.7V, but USB charging delivers power at 5V. This voltage conversion, combined with heat losses during charging, means you receive approximately 60–70% of the advertised capacity at the charging output. A 10,000mAh power bank typically delivers 6,000–7,000mAh of usable charging capacity. This is not deceptive — it is physics — but understanding it helps you choose the right capacity for your needs.
Frequently Asked Questions
Can I take a power bank on a plane?
Yes, but only in carry-on baggage — never in checked luggage. Lithium battery regulations prohibit power banks in the hold due to fire risk. Most airlines permit power banks up to 100Wh capacity (approximately 27,000mAh) in carry-on. Power banks between 100Wh and 160Wh require airline approval. Power banks above 160Wh are not permitted on commercial flights. Always check your specific airline’s current policy as rules can vary.
How many times can a 10,000mAh power bank charge a phone?
A 10,000mAh power bank typically delivers 2–3 full charges to a modern smartphone with a 3,500–4,800mAh battery. The exact number depends on the phone’s battery size, the power bank’s efficiency and whether fast charging is used. Due to voltage conversion losses, expect approximately 60–70% of the advertised capacity as actual charging delivered to your device.
Can a power bank charge a laptop?
Yes, if the power bank has a USB-C output of at least 45W and the laptop supports USB-C charging. Most modern MacBooks, Dell XPS, ThinkPad and HP Spectre laptops charge via USB-C. Power banks with 100W+ output like the Anker 737 and Baseus Blade charge laptops at or near their maximum charging speed. Lower-wattage power banks will charge laptops slowly or simply maintain battery level rather than actively charging.
How long does it take to recharge a power bank?
Recharge time depends on the power bank’s self-charging input speed and the charger used. The Anker 737 accepts up to 65W input via USB-C, allowing it to recharge from flat in approximately 2.5 hours with a compatible charger. Budget power banks often accept only 5–10W input, taking 8–12 hours to recharge — a significant practical limitation for travellers. Always check the input wattage specification when purchasing.
Final Verdict
For most travellers, the Anker 521 PowerCore 10,000mAh is the ideal starting point — lightweight, fast-charging and affordable at $26. Travellers who need laptop charging capability should invest in the Anker 737 for maximum capacity or the Baseus Blade for slim design. iPhone users will love the Anker 633 MagGo‘s cable-free convenience. Whatever you choose, carrying a power bank on every trip is one of the simplest quality-of-life improvements available to any traveller — the peace of mind of knowing your devices will stay charged through the longest travel days is worth every penny.
