Best Power Bank for International Travel: 4 Expert Picks

best power bank for international travel

Imagine being on a long flight, your phone battery dwindling, and no outlet in sight to save the day. Even if there’s an outlet nearby, it’s painfully slow—barely keeping your phone alive.

That’s why a power bank, also called a portable charger, is a travel essential. It keeps your devices powered up and ready for anything, no matter where you are.

In this guide, we’ll highlight the best power banks for international travel, so you can stay connected and stress-free on your journey.

1. What is a Power Bank?

power bank is a portable device that stores electrical energy and allows you to charge your gadgets—such as smartphones, tablets, laptops, or other USB-powered devices—on the go. Basically, it’s a backup battery you carry with you to ensure your devices don’t run out of juice when you’re away from a power outlet.

Power banks come in a variety of sizes and capacities, typically measured in milliamp hours (mAh). The higher the mAh rating, the more energy the power bank can store, which means more charges for your devices. However for plane travel, there are FAA rules. 

You’ll also need accessories like charging cords and bases, which we’ve detailed in our recommendations. For added convenience, look for power banks that come bundled with charging bases or feature pass-through charging. This allows you to charge your device and the power bank at the same time—perfect for busy travelers.

Rest assured, every option we’ve selected complies with FAA standards for air travel.


2. Best Power Bank for International Travel Based on Use

Different devices have different power needs, so it’s important to choose a power bank with the right capacity. For example, charging a laptop requires a power bank with higher wattage compared to one for a cell phone. Our testing is rigorous. Learn how we made our selections.

  1. Under 100 Wh (Most Power Banks)
    • Allowed in Carry-On: Power banks with a capacity of 100 Wh or less can be carried in your carry-on luggage without airline approval.
    • Examples: This includes most consumer power banks like those used for phones, tablets, and laptops, typically with a capacity under 27,000mAh at 3.7V.
  2. Between 100 Wh and 160 Wh
    • Allowed with Airline Approval: Power banks with a capacity between 101 Wh and 160 Wh can be carried in your carry-on luggage only with airline approval prior to the flight.
    • Examples: This range often covers larger power banks used for medical devices or professional equipment.
  3. Above 160 Wh
    • Prohibited: Power banks with a capacity exceeding 160 Wh are not allowed in either carry-on or checked luggage.

5. How to Pack Your Power Bank

5.1 Power Banks Allowed ONLY in Carry-On Luggage

Power banks are allowed in carry-on luggage, but there are specific regulations you must follow depending on their watt-hour (Wh) rating. These rules are enforced by the FAA, IATA, and other aviation authorities worldwide to ensure safety during flights.

Key Rules for Carry-On

  1. Power Banks Under 100 Wh
    • Allowed: No airline approval needed.
    • No Quantity Limit for Under 100Wh: You can carry multiple power banks under 100Wh for personal use, as long as they fit in your carry-on.
    • Covers most consumer power banks (e.g., for phones, tablets, and laptops).
    • Example: A power bank with 26,800mAh at 3.7V is 99.16Wh, making it permissible.
  2. Power Banks Between 101–160 Wh

    • Use original packaging, battery cases, or place tape over the terminals.

5.2 Why Power Banks Are Prohibited in Checked Bags

  1. Fire Risk:
    Lithium-ion batteries, including those in power banks, pose a risk of thermal runaway, which can cause fires. Fires in the aircraft cabin are easier to detect and manage compared to the cargo hold.
  2. Aviation Regulations:
    • FAA (Federal Aviation Administration): All spare lithium-ion batteries and power banks must be carried in carry-on luggage.
    • IATA (International Air Transport Association): Prohibits lithium-ion power banks in checked luggage to minimize fire risks.
  3. Size Limit for Carry-On:
    • Power banks under 100Wh can go in carry-on luggage without airline approval.
    • Power banks between 101–160Wh require airline approval but still cannot go in checked luggage.
    • Power banks over 160Wh are strictly prohibited in both carry-on and checked luggage.

Curious about what you CAN bring in that checked suitcase?

5.3 What Happens If You Pack a Power Bank Checked Luggage?

  • Confiscation: Airlines may remove the power bank from your checked bag during screening.
  • Denied Boarding: If detected during security screening, you may be denied boarding
  • Fines or Penalties: Depending on the airline and local aviation rules, you could face fines for violating safety regulations.

5.4 Key Takeaways

  • Power banks of any size must go in carry-on baggage and cannot be checked.
  • Ensure your power bank is under 100Wh or, if between 101–160Wh, obtain prior airline approval.
  • If your power bank exceeds 160Wh, it is not allowed on the plane at all.

6. Did You Know?

6.1 Power Banks Have a Shelf Life

Even if unused, power banks degrade over time. Typically, a power bank’s lithium-ion or lithium-polymer battery can last around 300-500 charge cycles before its capacity starts to decline. Regular use and recharging can help prolong its lifespan.

6.2 Not All Power Banks Support Every Device

While most power banks are versatile, not all of them can power every type of device. For example, some older or low-output power banks might not provide enough wattage to charge high-demand devices like laptops, CPAP machines, or newer tablets that require 60W+ USB-C Power Delivery.

6.3 Higher Capacity Doesn’t Always Mean More Charges

The actual number of charges you get from a power bank depends on both the power bank’s efficiency and the device being charged. Factors like the power loss during charging (conversion inefficiency) and how much power the device needs affect how many full charges you can expect. For example, a 20,000mAh power bank will charge a high-powered device like a tablet fewer times than a smartphone.

6.4 Cold Weather Can Drain Power Banks Faster

Extreme temperatures, especially cold, can affect the efficiency and lifespan of power banks. In freezing temperatures, the lithium-ion batteries in power banks can drain more quickly and may lose their ability to hold a charge effectively. It’s best to store and use power banks in moderate temperatures to ensure optimal performance.

6.5 Some Power Banks Offer Solar Charging

Solar-powered power banks have built-in solar panels that allow them to charge using sunlight. While solar charging is typically slow and should not be relied upon as the primary power source, it can be a handy backup in outdoor or remote environments when conventional charging methods aren’t available.

6.6 Pass-through Charging Isn’t Always Standard

Many people assume all power banks offer pass-through charging—the ability to charge a device while the power bank itself is being charged. However, this feature isn’t present in all models, especially budget options. If you need pass-through charging, be sure to check the specs before purchasing.

6.7 Power Banks Can Charge Drones and Cameras

High-capacity power banks with AC outlets or high USB-C Power Delivery output can be used to charge drones, action cameras, and professional photography equipment, making them a useful tool for adventure travelers or professional photographers. This is especially useful for remote shoots or long outdoor expeditions.

6.8 They Can Power Small Appliances

Some larger power banks, typically with AC outlets, can power small devices such as mini-fridges, portable fans, or even small projectors. These high-capacity models are useful for camping trips, long road trips, or in situations where access to power is limited.

6.9 Wireless Power Banks Exist

Some power banks come equipped with Qi wireless charging, allowing you to charge compatible devices without plugging in a cable. Just place your smartphone on the power bank’s charging pad, and it will start charging wirelessly. This feature can save time and reduce cable clutter.

6.10 USB-C Power Delivery Can Speed Up Your Power Bank’s Recharge

Power banks with USB-C PD (Power Delivery) don’t just offer faster charging for your devices—they also allow the power bank itself to recharge much faster. Instead of taking up to 8 hours to fully charge a high-capacity power bank, USB-C PD can reduce that time to as little as 2-3 hours, which is especially useful for busy travelers.


7. Frequently Asked Questions (FAQ’s)

7.1 Can I take a power bank on a plane?

Yes, you can take a power bank on a plane, but it must be packed in your carry-on luggage. If you’re using it to power medical devices, make sure the power bank complies with airline regulations. Most airlines limit power banks to 100Wh (Watt-hours), but larger ones may be allowed with prior approval. Always confirm with the airline if you’re carrying a power bank for critical medical devices.

7.2 How long does it take to fully charge a power bank?

Charging times depend on the power bank’s capacity. Smaller power banks (10,000mAh) take about 3-4 hours, while larger ones designed for medical devices (like 20,000mAh or 50,000mAh) may take 6-8 hours. If you need to recharge quickly, look for models with fast-charging capabilities like USB-C Power Delivery.

7.3 Do power banks lose charge over time?

Yes, power banks will slowly lose their charge if left unused for extended periods. Most quality power banks retain a significant portion of their charge for several months, but it’s a good idea to recharge them every 3-6 months to ensure they’re ready when you need them.

7.4 What is pass-through charging, and do all power banks offer it?

Pass-through charging is the ability to charge devices while simultaneously charging the power bank itself. Not all power banks support this feature, so if it’s important to you, be sure to check the product specifications.

7.5 Can power banks charge medical devices like CPAP machines or insulin pumps?

Yes, power banks with high capacity and AC outlets or USB-C Power Delivery can charge medical devices. When traveling with critical equipment like CPAP machines, ensure your power bank provides enough output (usually 60W or higher) and check if the device is compatible with your medical equipment.


8. Wrap Up

When it comes to international travel, staying connected is so important—whether for work, entertainment, or safety. In some cases, that power bank operating at the right capacity is crucial to your health or to that of a loved one.

The approriate battery backup can make all the difference in ensuring the devices you depend on stay charged throughout long flights, layovers, hotels or adventures in places where outlets may be hard to find.

Always consider the capacity, number of ports, charging speed, and airline regulations, so you’ll be better equipped to choose a power bank that fits your needs. And be sure to give it a test run, before you board; makes life much easier.
