When you're on the go, a flat phone battery can be a serious issue. It's not rare to find boarding passes, train tickets, and maps stored on the same device, and having a reliable charging solution on the go is helpful even if you're taking a short trip.
But not every power bank with the highest capacity is the best power bank for travel. For a weekend city break, there needs to be something that is compact and easy to carry, but business travel might need the output to power a laptop. Camping, road trips, and campervan holidays to all intents and purposes have different power requirements.
Portable power stations that are more than a pocket-sized battery can be more flexible than a pocket-sized battery for longer trips where you might be away from your mains electricity for more than a day or two. They will allow compatible USB devices to be supported, plus larger electronics – but their additional capacity also results in extra size and weight.
So, depending upon your mode of travel, what you want to charge, and when you have access to a socket, you have to decide which is the right choice for you.
What makes a good power bank for travel?
The ideal travel power bank will be able to hold enough power without becoming cumbersome. When making comparisons between brands/capacities, consider what will be in your bag.
Battery capacity and charging needs
The most common way to measure the power bank capacity is in milliamp-hours (mAh). Generally, the higher the number, the more energy is stored.
5,000mAh could be sufficient for those seeking an emergency phone top-up. For those who plan on charging their phone multiple times or with a partner, it could be more worthwhile to pick something in the 10,000mAh to 20,000mAh range.
For laptop users, one more factor comes into play – output power. The large-capacity battery does not necessarily make a good match for a laptop when the USB-C port can't deliver the requisite wattage.
Note also that actual headspace capacity does not equal usable capacity. You won't get all the mAh back to your phone or laptop, as some will be lost when converting voltage, through cables, and as heat.
Size, weight, and portability
Capacity comes at a physical cost. The bigger the battery, the heavier and bulkier it is.
However, if you plan on walking around a city all day, a smaller power bank that fits into a small bag might be more convenient than a larger 30,000mAh power bank. If you don't like to carry it, then the extra capacity is of little use.
For travellers comparing smaller models, EcoFlow's guide to choosing the best portable power bank offers additional context on the features worth considering.
Consider the journey, not just the flight itself. Technically, a battery can go in your cabin bag, but you'll still need to carry the battery through sightseeing days as well as at airports or railway stations.
Charging speed and USB-C power delivery
Capacity tells you a power bank's energy storage capacity. The ability to deliver that energy is related to its output.
This is especially helpful for today's smartphones, tablets, and compatible laptops, known as USB-C Power Delivery, or USB-PD. To achieve higher charging speeds, however, the charging standard must be supported by the power bank, cable, and device.
The user of a telephone might be completely happy with a small volume. Depending on the laptop, it will require 45W, 65W, or more.
Look at the wattage recommended by the laptop manufacturer and don't just take it for granted that it will charge fine with any kind of USB-C battery.
Ports and charging multiple devices
If you are travelling solo with a phone, then one USB-C port is likely to suffice. If you have a tablet, camera, earbuds and a laptop, then more ports are worth more.
Don't just consider the number of ports, but also how power is split between them. When no other device is connected to the power bank, it might deliver 100W, but when connected to another one that needs 20W, the power bank's output drops to 20W.
Some models have an inbuilt charging cable, so it doesn't require having to pack one. However, the separate cables make replacing a damaged cable easier.
What is the best size power bank for travel?
There is no universal answer, as the best capacity varies according to trip distance and device usage.
It isn't just a question of what the largest battery I can purchase is. It's, “How much energy will I need between charges?”
5,000mAh–10,000mAh for short trips
If you're taking a day trip, commuting, or heading off on a weekend city break, 5-10,000mAh may be a good range of power to consider.
A 5,000mAh battery is particularly helpful if portability is more important than getting multiple charges. Can be used as a quick boost for emergency use with little added weight.
Around 10,000mAh provides the ability to use a phone for much longer periods, for navigation, photography, and heavy phone use, and it is still somewhat compact.
This range will usually suffice for most travelers who are able to get a charge at a hotel every night.
20,000mAh–30,000mAh for longer journeys
For those who are away from wall outlets for extended periods of time, 20,000mAh or more might be preferable.
This can come in handy when you have multiple USB devices, a laptop that is compatible, or if you are traveling as a couple and need to charge one. It also gives a boost of extra legroom on a long train ride, multi-day road trips, or a long-distance stay.
The drawback to this is weight. A 20,000mAh unit will obviously be larger than a 600mAh unit that you'd normally hook up to your phone. A unit of 20,000mAh or 30,000mAh will be quite a bit bigger than a regular 600mAh charger.
Another aspect of large batteries to pay attention to is when flying, as aviation rules are based on watt-hours and not just mAh.
Understanding mAh, Wh, and real-world capacity
Milliamp-hours are used to indicate electrical charge, and watt-hours are used to indicate electrical energy stored.
A basic conversion is the following:
Wh = (mAh × battery voltage) ÷ 1,000
For instance, a 20,000 mAh power bank that has a nominal voltage of 3.6V is roughly:
20,000 × 3.6 ÷ 1,000 = 72Wh
The implications of this are for air travel, because aviation restrictions are given in watt-hours.
There will still be energy losses due to conversion, resulting in less energy actually being used to charge than is theoretically possible. Power banks of the same advertised capacity can yield slightly different performance in use.
Best power banks for different travel needs
No single power bank exists that is ideal to use for travelling in all cases. The needs of a person traveling with just a phone will differ from a person traveling with a work laptop and camera kit.
Best lightweight power bank for travel
When it comes to sightseeing, commuting, and short trips, consider weight over maximum capacity.
A 5,000mAh battery or a 10,000mAh battery may be more convenient to carry around all day and still have a decent amount of juice left for a smartphone.
A thin design can also be more easily tucked into the pocket of a jacket or handbag than a thick block of battery.
Never carry more than two batteries, more than are necessary, because the higher number seems better in the specifications.
Best phone and iPhone power bank for travel
When it comes to charging phones, compatibility and convenience are more important than extreme output.
The 10,000mAh power bank is a great option for anyone who needs more power than the device was providing. It doesn't need to be too big to serve as an extra source of fuel during an emergency.
For the iPhone, verify the charging port and charging capabilities for the particular model. More devices are using USB-C, and magnetic wireless charging could be a good option for convenience as well.
When charging speed is paramount, wired charging is often very simple and effective.
This guide to selecting a power bank for Apple devices includes extra factors to consider if you're specifically searching for an Apple-compatible device.
The best iPhone power bank for traveling, however, isn't necessarily the one with the most gigawatt-hours. But portability, compatibility, charging output, and usage are all important as well.
Best laptop power bank for travel
Laptop charging requires more care.
Prepare to see if your laptop can be charged via USB-C. Then, find out its expected wattage usage. The power bank is rated for only 20W and is good enough for your phone, but not your laptop, which requires a 65W adapter.
Capacity is also an important consideration: Laptop batteries hold a lot more energy than phone batteries.
Business travellers can use a USB-C PD power bank to charge a laptop and phone in a single power point throughout the day.
When power isn't available, whether you're traveling outside the hotel and office space, EcoFlow's guide to charging a laptop and phone while camping is also helpful for understanding how your charging needs differ.
Best power bank for international travel
International travellers should consider regulations and performance.
Look for a battery that has the Wh rating prominently on the outside, and do not remove the manufacturer's label. It is more convenient to fly with a capacity that is well below the threshold of the relevant airline than one that is just shy of the threshold.
Look at all of your airlines. If a connecting flight is required, it can be flown by a different airline that has its own restrictions.
When it comes to international travel, simplicity trumps complexity: a small, well-labeled battery with enough USB-C ports to connect your gadgets and a clear, easy-to-understand capacity that meets the legal standards set by the airline.
Best Anker power bank for travel: What to consider
The same criteria are applied when buying a power bank for travel regardless of brand, but travellers search more specifically for the best Anker power bank for travel.
Check:
Battery capacity
Watt-hour rating
USB-C output
Number of ports
Weight and dimensions
Device compatibility
Current airline requirements
However, model features and specifications do evolve, and it is better to choose a power bank based on features and travel needs than to think of one model as the "best" forever.
Can you take a power bank on a plane?
Typically, it is, but there are significant limitations.
Many other electronic accessories can be safely discarded with household trash, but lithium batteries are treated differently, as they can cause a fire if damaged, overheated, or shorted out.
There were also changes in the rules in 2026, so it's worth checking the current rules before following an older travel article.
Airline capacity limits and battery rules
The current guidance from the UK Civil Aviation Authority (CAA) states that lithium-ion power banks of up to 100Wh can be carried without operator approval. Power banks of more than 100Wh but not more than 160Wh must be authorized by the operator.
There's a big problem with travelling abroad in 2026, though.
IATA guidance after the March 2026 rule changes says that the current addendum to the ICAO allows for up to 160Wh, but this is not planned to remain in the next edition of the IATA Dangerous Goods Regulations.
Therefore, it is crucial to look into the individual airline's policy when there is a battery that is close to or over 100Wh.
If it is a simple flight or trip, it would be easier to stay at or under 100Wh.
Carry-On vs. checked baggage
Please carry the power bank in your cabin baggage, not checked baggage.
The rules of the CAA (Effective from 27 March 2026) impose the following requirements on power banks:
Be carried in carry-on bags.
When not in use, be individually protected from short circuits.
Not be recharged while on board
Not have the capability to charge other portable electronic devices on board, as per the recommendation of the CAA
Be limited to a maximum of two per person
Remove power banks if the person who is checking you in at the gate asks you to place your cabin bag in the hold.
If each unit is stored in a protective pouch or its original packaging, it can help minimise the risk of exposed terminals coming into contact with metal objects.
What to check before international travel
Before you go to the airport, check:
Wh rating of the battery.
If your airline allows this capacity
Maximum power bank(s) to be carried:
Whether to ban the use of the internet in school or at school.
The procedure for getting the airline connected to the policy.
Check whether the battery has been damaged physically or not.
A swollen, cracked, or overheating power bank should not be taken on a flight.
Policies may be more stringent than the limits for general regulation, so it's best to confirm with the airline before travel.
When a traditional power bank isn't enough
A normal power bank is typically the best option for flights, trains, and everyday urban travel.
This is different if you are travelling for a few days without electricity.
Charging multiple devices over several days
Imagine two people heading out with their phones, laptop, camera batteries, earbuds, and rechargeable lights.
What appears to be a generous 10,000 mAh battery for a single day can be used up in a matter of minutes when multiple devices are running on it.
You might have several power banks, but that means more cables, power bank management, and extra batteries to monitor.
This is where it's more helpful to work out your total requirement for energy than to just calculate the number of devices you use.
Power needs for camping and road trips
Phones aren't the only tools you need for camping or a road trip.
Depending on the trip, you might want power:
Phones
Cameras
Laptops
Rechargeable lights
Portable refrigeration
Other compatible camping gear.
A standard USB power bank can't power larger appliances directly from AC.
Vehicle-supported camping allows for greater flexibility as you don't need to carry the entire energy system with you.
When to consider a portable power station
Portable power stations are useful when you want to store significantly more energy, more outputs, or AC outlets.
This is especially applicable for road trips and car camping, where you might want to charge phones and cameras, or may wish to have compatible lighting, a laptop, or portable refrigeration.
If camping is your main use case, this guide to choosing the best portable power station for camping provides more detail on matching capacity with outdoor power requirements.
But it's not a travel battery like the ones you can find on board an airline. The capacity of the units is measured in kilowatt-hours, much higher than the normal passenger power-bank capacity, and they are meant to be used for vehicle-supported or stationary applications.
Portable power stations for extended travel and off-grid power
When you choose a car, campervan, or multi-day campsite, the priority is to have a usable amount of energy available for the journey.
The DELTA 3 Max Series and DELTA Pro 3 are designed to meet the needs of two different levels of demand.
EcoFlow DELTA 3 Max Series for camping and road trips
EcoFlow DELTA 3 Max Series Portable Power Station offers 2,048Wh storage. It has 2 versions. The DELTA 3 Max has a weight of around 20.3kg with a maximum AC output of up to 2400W, while the DELTA 3 Max Plus weighs around 22.1kg with a maximum AC output of up to 3000W. Each of them has four AC outlets.
This makes the series more suitable for traveling in a vehicle than for normal sightseeing.
On a camping or road trip, the equipment that is compatible with the available capacity can include selected appliances, lighting, cameras, laptops, and phones. Time will vary depending on power draw and conversion losses of each device.
Solar charging is also available. The standard DELTA 3 Max can take up to 500W solar input, while the DELTA 3 Max Plus can take up to 1,000W solar input.
Even though it's called “portable,” it's crucial to consider weight. The 20kg+ battery can be moved from a vehicle to a campsite, but being carried around by sightseeing visitors would be impractical.
EcoFlow DELTA Pro 3 for higher-capacity travel and campervan setups
Charging phones is just one of many things that can happen on a campervan holiday. Electricity may be used for lighting, computers, refrigeration, and other equipment with similar uses.
Before choosing a large battery, it helps to list your essential campervan gadgets and estimate how much energy they actually use. This gives you a better basis for choosing storage capacity.
The EcoFlow DELTA Pro 3 Portable Power Station has a capacity of 4,096Wh for higher demand.
It provides 5 AC outlets and a total AC rating of 4000W, and a surge rating of 8000W. It also has a max solar charging input of 2600W with LFP battery chemistry.
There is a trade-off in terms of weight. The DELTA Pro 3 has a weight of 51.5kgs, which is much more suited to a camper van, motorhome, or vehicle base than for any type of regular carrying.
It can be expanded by the addition of up to two compatible smart extra batteries to increase the amount of stored energy available, for longer off-grid periods when needed.
Choosing the right capacity for your travel needs
Don't simply opt for "more" just because it's thought to be better.
Rather, estimate what kind of energy consumption you are likely to have.
It is quite simple to begin with:
Energy required (Wh) = device wattage × hours of use
If the laptop's power rating is 60W, and it is used for 3 hours, then the theoretical load is 180Wh. Another 160Wh is another 40W light used for 4 hours.
The actual usage of real-world batteries will be greater due to losses from conversion and background system activity.
It depends on the size of your trip, of course, but the best option will be apparent once you have a clear idea of the scale:
One phone to go on a city break: compact power bank
Phone and laptop on a flight: higher output power bank that meets airline requirements
Several devices while car camping: a portable power station may be useful
Portable higher power equipment plus campervans may be better suited: a larger portable power station may make more sense.
Travel power bank vs portable power station
A portable power station and a power bank address two different problems.
A power bank is made portable. A power station is built around the amount of energy that is produced and a wider diversity of energy outputs.
Before investing in bigger off-grid solutions, you might want to start with EcoFlow's recommendations for the best power bank for all your electronic needs.
Portability and weight
A traditional power bank beats it on the head when it comes to airport days, city vacations, or public transport and walking trips.
A relatively large 20,000mAh power bank is much easier to carry than the 20.3kg DELTA 3 Max.
Portable power stations are really useful if there is a car, caravan or campervan to provide most of the transport.
Consider where your battery is being transported.
Capacity and charging options
The primary function of the power banks is to charge via USB.
Portable power stations provide much greater energy storage capabilities and may contain:
USB-A
USB-C
AC outlets
12V DC outputs
Solar charging
Vehicle charging options
This means they are capable of accommodating a wider array of compatible equipment.
For example, the DELTA 3 Max Series adds solar input, 4 AC outlets, and USB charging to a standard phone battery, making it more useful for a campsite.
Choosing based on trip length and power needs
A simple comparison can help:
Travel situation | More practical choice |
Day trip | 5,000–10,000mAh power bank |
Weekend city break | Around 10,000mAh |
Long journey with several USB devices | 20,000mAh-class power bank |
Laptop on a flight | Airline-compliant high-output USB-C power bank |
Backpacking | Lightweight power bank |
Car camping | Larger power bank or portable power station |
Multi-day road trip | Portable power station |
Campervan with larger electrical loads | Higher-capacity portable power station |
These are guidelines rather than fixed rules. Your devices, charging frequency, and access to mains electricity should determine the final choice.
How to choose the best power bank for travelling
Once you realize that you don't need to handle every trip in the same manner, finding the best power banks for travelling will be considerably easier.
For Flights and City Breaks
Prioritise:
Low weight
Compact dimensions
Clear Wh labelling
USB-C charging
Consider the amount of space required for 1 or 2 devices.
Straightforward airline compliance
About 10,000mAh is a reasonable amount of storage for most travellers.
If you're going to need a hotel socket every night, then you don't need to bring several days' worth of stored electricity around town.
For business travel and laptop users
Consider laptop compatibility first.
Check:
Is the laptop USB-C charging compatible?
How many watts of input does it need?
Will the power bank deliver that power?
What is the relationship between output and the number of devices?
Is the battery within your airline's allowed Wh range for the airline?
A 20,000mAh-class USB-C PD phone and laptop combo will be helpful if your trip calls for a powerful boost, as long as its power output is compatible with your devices and it's aviation approved.
For camping, campervans and extended trips
Camping varies enormously.
A power bank is still a sensible option when backpacking and taking everything on your own.
Weight is less of a concern if you are car camping. This can then be stored in a portable power station to allow for enough energy to power several devices and compatible camp equipment.
The DELTA 3 Max Series is designed for a road trip or for just a regular car camping system; The range starts at around 20.3kg and includes 2,048Wh.
The DELTA Pro 3 doubles the base capacity to 4,096Wh and gives significantly increased AC output, but at 51.5kg weight, it is a vehicle-supported system.
You should choose based on actual energy calculations for your needs, not on the assumption that the biggest unit is the best one.
Conclusion
The best power bank for travel in 2026 will vary according to the actual travel scenario.
For flights, city breaks, and regular overseas travel, a compact power bank is still the most convenient option. Look for enough capacity to cover your devices, adequate USB-C output, and a battery size that you are comfortable carrying all day.
Rules for the airlines are also significant. After the changes in March 2026, power banks must be stored in hand luggage; There are two power banks per person and extra restrictions on their use and charging onboard. Before travelling, it is particularly crucial to check the airline before flying.
The calculation is different when travelling by road, camping or in a campervan. A portable power station can offer more power and more outputs for several devices or larger compatible electronics to operate for multiple days.
The main point is not to purchase the largest battery that you can obtain. Select the smallest, lightest, and most convenient power supply that can easily accommodate your trip.
Frequently Asked Questions
What is the best size power bank for travel?
If you're charging your phone for short periods and daily use, then 5,000mAh to 10,000mAh may suffice. Those who require multiple charges or who bring multiple USB devices along may prefer to go for around 20,000mAh. Also look at the battery Wh rating and the current rules of the airline when flying.
What is the best power bank for international travel?
Your best international travel power bank should be portable, easy to read, have a clear Wh rating, be compatible with your devices, and easy to fit in and comply with airline restrictions.

Make sure you read the conditions of each carrier on your travel schedule; don't assume the conditions on one airline are going to be the same for the whole trip.
Can I take a 20,000mAh power bank on a plane?
It is dependent on the watt-hour capacity. For instance, a 20,000mAh battery that has a nominal voltage of 3.6 volts comes out to roughly 72Wh—a level lower than the CAA's 100Wh limit for power banks brought without an operator's approval. It should also be packed in cabin luggage and abide by the airline's regulations.
What is the best power bank for charging a laptop while travelling?
Select the desired power bank with a USB-C PD port, depending on the laptop's power requirement. However, high power is not enough; The amount of charging wattage should also be appropriate. If flying, be sure that the battery's Wh rating meets current aviation and airline regulations.
Is a portable power station better than a power bank for camping?
It will depend on the style of camping. A lightweight power bank is typically more convenient when backpacking. A portable power station can be helpful for vehicle-supported camping if you need to power several items or power compatible items other than phones. For example, the DELTA 3 Max Series is considered a car-camping or road-trip product and has a starting weight of 20.3kg.
