A dead phone is inconvenient at home. It can become a serious problem when you’re travelling.
Your phone may be your boarding pass, map, camera, payment tool, translation device and primary way of contacting people. If you’re travelling internationally, you may also need it to access banking apps, ride-hailing services and hotel reservations.
That makes a portable charger one of the simplest pieces of travel technology you can pack.
But buying a power bank in 2026 isn’t as simple as choosing the one with the biggest number on the box. Capacity, charging speed, weight, ports, built-in cables and airline restrictions all matter.
We’ve looked at current 2026 models and specifications from manufacturers alongside recent independent testing and reviews to identify the options that make the most sense for different types of travellers.
What Makes a Good Travel Power Bank?
Before looking at specific models, there are four numbers and features worth understanding.
Capacity
Capacity is usually advertised in mAh (milliamp-hours).
Common sizes include:
- 5,000mAh: Emergency top-ups and very small bags
- 10,000mAh: Everyday travel and phone charging
- 20,000mAh: Longer trips and multiple devices
- 25,000mAh and above: Laptop users and heavy travellers
A larger capacity generally means more available energy, but it also means a heavier power bank.
Also, don’t assume a 20,000mAh power bank will deliver exactly 20,000mAh to your phone. Energy is lost during voltage conversion and charging, so usable output is lower than the headline battery capacity.
Output
Output is measured in watts (W).
A 10W power bank may charge a modern phone relatively slowly, while a 20W to 30W USB-C power bank can provide considerably faster charging to compatible phones.
If you’re charging a laptop, you’ll usually want considerably more.
For laptop travel, 65W is a useful starting point, while 100W or more gives you greater flexibility.
Ports
USB-C is now the most useful port to have.
A good travel power bank should ideally let you charge at least two devices, especially if you’re carrying a phone, earbuds, tablet, camera or laptop.
Weight
This is easy to overlook.
A 25,000mAh power bank can provide substantially more energy than a 10,000mAh model, but you’ll feel the difference in your backpack.
For a day of sightseeing, a compact 10,000mAh model may make more sense than a high-capacity laptop power bank.
Best Overall: Anker Laptop Power Bank 25K
If you want one power bank that can handle a phone, tablet and laptop, the Anker Laptop Power Bank 25K is one of the most versatile travel options available in 2026.
It has a 25,000mAh capacity, rated at approximately 90Wh, keeping it below the 100Wh threshold commonly used for passenger power banks. It can deliver up to 165W total output, with up to 100W available from an individual USB-C connection. It also has two built-in USB-C cables, reducing the number of cables you need to pack.
Why It’s Good for Travel
- 25,000mAh capacity
- Approximately 90Wh
- Up to 165W total output
- Up to 100W from a USB-C connection
- Two built-in USB-C cables
- Four-device charging
- Digital display
- Suitable for phones, tablets and many USB-C laptops
The biggest drawback is weight. At around 595g, this isn’t a power bank you’ll forget is in your bag.
Best for: Travellers carrying several devices or a USB-C laptop.
Best for Long Trips: UGREEN Nexode 25,000mAh 200W
If charging speed and capacity matter more to you than having the lightest possible power bank, UGREEN’s Nexode 25,000mAh 200W is worth considering.
The power bank has a 25,000mAh capacity rated at 90Wh, two USB-C ports and one USB-A port. Its first USB-C port can deliver up to 140W, while the second supports up to 100W.
It weighs approximately 609g, making it slightly heavier than the Anker model above.
The advantage is the combination of capacity and high USB-C output, particularly if you carry a laptop that supports USB-C charging.
Best for: Laptop users who want high charging output and multiple ports.
Best for a Lightweight Trip: A 10,000mAh Power Bank
If you’re travelling with just a phone, don’t automatically buy a 25,000mAh power bank.
A 10,000mAh model is much easier to carry and can provide useful backup power for a typical day away from a wall outlet.
Recent 2026 testing and buying guides continue to include compact 10,000mAh models among their recommended options for travellers who prioritise portability.
Look for:
- USB-C input and output
- At least 20W output if your phone supports fast charging
- A reputable manufacturer
- Clear battery-status indicators
- A weight you won’t mind carrying all day
Best for: Sightseeing, short trips and phone-only travel.
Best for iPhone Users: Anker MagGo 10K Qi2
If you have a compatible iPhone, a magnetic Qi2 power bank can make travel charging considerably more convenient.
Instead of carrying a cable and holding the phone connected to a power bank, a compatible magnetic power bank attaches to the back of the phone.
The Anker MagGo Power Bank 10K with Qi2 is one of the current options highlighted in 2026 testing. WIRED includes it among its recommended magnetic portable chargers.
The trade-off is straightforward: wireless charging is convenient, but wired USB-C charging is generally the better choice when you want maximum charging efficiency and speed.
Best for: iPhone users who value cable-free convenience.
Best Budget Choice: UGREEN Nexode 12,000mAh 100W
You don’t necessarily need a huge battery to get fast charging.
The UGREEN Nexode 12,000mAh 100W is a smaller option that combines relatively high output with a more travel-friendly capacity. Tom’s Guide currently lists it among its 2026 recommendations and describes it as a compact budget option.
It’s particularly interesting for people who want fast USB-C charging without carrying a 20,000mAh or 25,000mAh battery.
Best for: Travellers who want high output in a smaller package.
Best for Business Travel: A Power Bank With Built-In Cables
If you’re travelling for work, every extra cable in your bag adds another thing to remember.
A power bank with built-in USB-C cables can simplify your setup.
The Anker Laptop Power Bank 25K is particularly practical here because it combines a 25,000mAh battery with two integrated USB-C cables.
That means you can leave one or two charging cables at home, depending on your devices.
Best for: Business travellers and people carrying several USB-C devices.
What About 30,000mAh or 40,000mAh Power Banks?
This is where you need to be careful if you’re flying.
A large mAh figure doesn’t automatically mean a power bank is prohibited on an aircraft. Airlines and regulators use watt-hours (Wh) rather than mAh alone.
The FAA says spare lithium-ion batteries and power banks rated at 100Wh or less can generally be carried in carry-on baggage. Batteries between 101Wh and 160Wh require airline approval and are limited to two spare batteries under FAA rules. Power banks must not be placed in checked baggage.
That’s why many travel-focused power banks sit around the 20,000mAh to 26,000mAh range.
For example, the Anker 25K is rated at about 90Wh, while the UGREEN 25K is also rated at 90Wh.
The Important Rule: Don’t Pack Your Power Bank in Checked Luggage
This is one travel rule you should remember.
Power banks are spare lithium batteries, so they belong in your carry-on baggage, not your checked suitcase.
If your carry-on is taken at the gate and placed in the aircraft’s hold, remove the power bank and keep it with you in the cabin.
IATA’s 2026 passenger guidance also notes that airlines may impose additional restrictions, including limits on the number of power banks passengers can carry and restrictions on their use during flights.
Always check the rules of your specific airline before travelling.
How Many Times Will a Power Bank Charge Your Phone?
Don’t calculate this using the advertised mAh figure alone.
A 10,000mAh power bank won’t necessarily provide two complete charges to a phone with a 5,000mAh battery.
There are conversion and charging losses between the power bank’s cells and your phone.
As a practical rule, expect fewer charges than a simple mAh-to-mAh calculation suggests.
For example, a 10,000mAh bank can be useful for roughly one to one-and-a-half full smartphone charges depending on the phone, power bank and charging conditions.
Larger 20,000mAh and 25,000mAh models can provide substantially more backup, but the exact number varies by device.
Do You Need 100W or 140W?
Probably not if you’re only charging a phone.
Most smartphones don’t need anywhere near 100W from a power bank.
Higher wattage becomes useful when you’re charging:
- MacBooks
- Windows laptops
- Gaming handhelds
- High-powered tablets
- Multiple devices simultaneously
If your main device is a phone, prioritise size and weight over headline wattage.
If you’re carrying a laptop, check its USB-C charging requirements before buying.
Are Wireless Power Banks Worth It?
They can be.
Wireless power banks are convenient because you don’t need to connect a cable to your phone. Magnetic models can be particularly useful for compatible iPhones.
But wired charging still has advantages:
- Usually faster
- Generally more efficient
- Works with more devices
- Doesn’t require precise alignment
For travel, a hybrid model that supports both wireless and wired charging gives you the most flexibility.
What to Look for When Buying a Power Bank
If you’re buying a portable charger locally, don’t focus only on capacity.
Look for:
A reputable brand
Cheap, poorly labelled power banks can have questionable battery quality and inaccurate capacity claims.
USB-C Power Delivery
USB-C PD is particularly useful if you carry modern phones, tablets or laptops.
Clearly stated specifications
Avoid products that advertise enormous capacities without providing clear information about watt-hours, output and input.
Safety protections
Look for protection against issues such as overcharging, overheating and short circuits.
A real warranty
A warranty from a reputable seller or manufacturer gives you more recourse if the battery develops a fault.
Which Portable Charger Should You Buy?
| Type of traveller | What to look for | Suitable capacity |
| Day trip | Small and light | 5,000–10,000mAh |
| Weekend traveller | Phone + accessories | 10,000–20,000mAh |
| International traveller | Multiple devices | 20,000–25,000mAh |
| Laptop traveller | USB-C PD, high output | 20,000–26,000mAh |
| Business traveller | Built-in cables + display | 20,000–25,000mAh |
| iPhone user | Qi2 + USB-C | 5,000–10,000mAh |
The best portable charger 2026 depends on what you’re actually carrying.
For someone travelling with a phone, tablet and laptop, the Anker Laptop Power Bank 25K offers an excellent combination of capacity, high USB-C output and built-in cables.
If maximum USB-C charging power is the priority, the UGREEN Nexode 25,000mAh 200W is another strong option, with up to 140W available from its primary USB-C port.
For lighter travel, a good 10,000mAh USB-C power bank makes more sense. And if you use a compatible iPhone, a Qi2 magnetic power bank can be worth the convenience.
The most important thing is to buy according to your devices rather than the biggest number on the box.
And if you’re flying, remember the rule that matters most: keep your power bank in your carry-on and check your airline’s current battery restrictions before you leave for the airport.
