10 Best Power Banks That Last Long Flights And Delays

Ever sat through a long-haul flight or unexpected delay with your phone on 4% and no outlet in sight? Having one of the best power banks can make all the difference. Here's a list of portable chargers for travel that actually hold up when your journey stretches beyond plan.

Anker Powercore 26800 – Dependable, Durable, And Massive Capacity

The Anker PowerCore 26800 is often mentioned for good reason. With a capacity of 26,800mAh, this bank can charge an iPhone more than six times or a tablet twice before needing a recharge.

Why it works well for long trips is not just capacity—it also has three USB output ports. This means you can charge your phone, tablet, and earbuds all at once. It supports fast charging too, so you won't be waiting forever.

Despite the large battery, it doesn’t feel bulky. For anyone frequently dealing with long layovers or multi-flight itineraries, this one has your back.

Baseus 20,000mah 65W – For Those Who Travel With A Laptop

Need something that goes beyond just your phone? The Baseus 65W is designed with both smartphones and laptops in mind. It has a USB-C port with enough output to charge a MacBook Air, making it great for business travelers or digital nomads.

What makes it stand out is the balance—20,000mAh is enough for a long trip, but the form factor still fits easily in a backpack or carry-on pocket.

The digital display shows how much battery is left, so you’re never guessing.

INIU 20000mah Portable Charger – Budget-Friendly Without Cutting Corners

If you’re looking for one of the best power banks without spending too much, INIU has built a reputation for quality at a low cost. This 20,000mAh charger can deliver power to phones, headphones, tablets, or even a Nintendo Switch.

Its slim design fits well into small travel bags, and it includes dual ports for simultaneous charging. One extra detail? It has a built-in flashlight, which is actually helpful during red-eye flights or when rummaging through your bag under dim cabin lights.

Mophie Powerstation Xxl – Sleek Design, Reliable Charge

Mophie isn’t always the first name people mention, but the Powerstation XXL is a solid pick. It offers 20,000mAh of battery life, wrapped in a fabric finish that makes it feel a little more premium.

The power bank has multiple USB ports and supports fast charging. It’s more about solid performance than flashy extras. Travelers who appreciate products that work quietly in the background will likely enjoy this.

Zendure Supertank Pro – Premium Charger For Serious Travelers

The Zendure SuperTank Pro feels like something designed for tech-heavy travelers. It holds 26,800mAh and has four USB-C ports, each capable of delivering fast charging power—even to larger devices like tablets or laptops.

What makes this one stand out is its OLED screen that gives detailed battery and device status info. If you’re the kind of person who flies with a phone, iPad, wireless earbuds, and a second phone or camera, this bank has the muscle for it.

The aluminum casing also gives it extra durability for rougher travel days.

Anker Powercore Slim 10000 – Lightweight And TSA-Friendly

Some trips don’t require max capacity—just a little peace of mind. The Anker PowerCore Slim 10000 fits that niche. It’s TSA-approved for carry-on, weighs less than a modern phone, and slips easily into a jacket pocket or handbag.

It charges most phones about twice and supports USB-C input and output. It's a smart pick for short-haul flights or as a second backup in case your main power bank runs out of power mid-trip.

UGREEN 145W 25000mah – Ideal For Power Users

The UGREEN 145W charger pushes the line between portable and powerful. It can fast-charge a laptop while still supporting phones and tablets simultaneously.

You get a high-capacity 25,000mAh cell with a clear display and three charging ports. This makes it ideal for people who travel with multiple devices that all need to be fully charged. Whether it's editing on the go, attending virtual meetings from the airport, or watching content on your tablet, this bank is designed for constant, reliable output.

Nimble Champ Pro 20000mah – Eco-Friendly And Efficient

If sustainability matters to you, the Nimble Champ Pro brings strong performance with a lower carbon footprint. It’s made with recycled materials and comes in packaging that’s 100% plastic-free.

It delivers up to 60W output with dual ports and has a quick recharge cycle. The compact shape and lighter-than-average weight also make it easy to bring on board without fuss.

Ravpower PD Pioneer 20000mah – Fast Charging With Smart Output

The RAVPower PD Pioneer gives consistent performance at a fair price. You get 20000mAh with a Power Delivery port that adapts to what’s connected—fast for phones, efficient for smaller devices like earbuds or fitness trackers.

It’s especially useful for people who travel with different gadgets and want something that intelligently adjusts without manual tweaking. It’s also one of the faster banks to recharge itself, which is helpful during layovers.

Goal Zero Sherpa 100pd – Outdoor Meets Business Travel

Originally designed with outdoor use in mind, the Goal Zero Sherpa 100PD performs surprisingly well in airports and hotels, too. With 25,600mAh capacity and wireless charging built in, it offers multiple ways to power up your devices.

Its rugged design is meant to last, whether you’re on a cross-country train ride or caught in a storm-related delay. The wireless charging pad is handy when your cable disappears in your bag (again).

It’s on the expensive side, but travelers who hate surprises and need reliability often find it worth the price.

Which One Is Right For Your Travel Style?

There’s no one-size-fits-all answer when choosing the best power banks for travel. If you're a light packer, something slim and simple like the Anker PowerCore Slim 10000 will do the trick. If you’re working on the go or traveling with several devices, the Zendure SuperTank Pro or UGREEN 145W offer serious power without being overkill.

Some prioritize eco materials, others want something that can charge a laptop in a pinch. But the key is picking a power bank that lasts a full day (or two) when outlets are miles—or hours—away.

Staying Charged On Long Trips

Whether you’re stuck on a runway, exploring a remote destination, or just juggling device use at a busy airport, portable chargers for travel are no longer just handy—they’re necessary. Look for battery size (measured in mAh), number of ports, weight, and output speed when choosing yours.

A long flight or delay doesn’t need to end in battery anxiety. With one of the best power banks in your carry-on, your tech can keep up with you—even when the trip doesn’t go as planned.
