Prime Power Bank (26K, 300W)
6
If you’re traveling with a laptop, tablet, and phone and need all 3 devices fully charged for a 15-hour flight, the Anker Prime Power Bank is the one to pack. With a 26,250mAh capacity and an impressive 300W total output across two USB-C ports and one USB-A port, it’s one of the most powerful portable chargers available for air travel.
What makes it stand out for long flights is its sheer speed. It delivers up to 140W through its main USB-C port, which can bring a 16-inch MacBook Pro from zero to 50% in roughly half an hour. Anker’s ActiveShield 2.0 technology monitors temperature over 3 million times per day, keeping everything safe even while charging multiple devices at once. The smart display shows real-time battery levels and wattage output, so you always know exactly where you stand. At under 100Wh, it stays within most airline carry-on regulations. It’s a premium investment, but for frequent long-haul travelers, it’s worth every penny.

737 Power Bank (PowerCore 24K)

The Anker 737 Power Bank is one of the most capable mid-range options for long-haul travel. It packs a 24,000mAh battery into a sturdy metal shell and delivers up to 140W output via USB-C Power Delivery 3.1, making it more than capable of fast-charging most modern laptops.
We love that it can charge an iPhone 14 to 50% in just 37 minutes, and with three ports (two USB-C, one USB-A), you can keep up to 3 devices topped off at the same time. The smart digital display gives real-time readouts on battery percentage, port wattage, and temperature. A full recharge of the power bank itself takes as little as one hour with a compatible 140W PD wall charger, which means you can top it up at the airport lounge and hit the flight fully loaded. At $109.99, it hits a sweet spot between performance and value that makes it one of our top picks for long-haul flights.

The Anker Prime Power Bank (20K, 220W) is a powerhouse that fits into a smaller package than its 26K sibling. With 20,000mAh of capacity and up to 220W total output, it’s more than capable of keeping your laptop, phone, and tablet alive through even the longest international routes.
What makes this model particularly well-suited for long flights is its balance of capacity and size. It’s noticeably more compact than most high-wattage power banks, yet it still delivers the kind of fast, multi-device charging that frequent flyers depend on. The smart display tracks charging status across all ports, and Anker’s ActiveShield 2.0 keeps temperatures in check the entire time. It supports up to 140W input for rapid self-recharging, so plugging into an airport lounge for 30 minutes gives you a meaningful charge boost before boarding. At $125.99, it’s an excellent choice for travelers who want Prime-level performance without the extra bulk.

Sometimes you just need a small, reliable backup charger that doesn’t add much weight to your carry-on. That’s exactly what the Anker Nano Power Bank delivers.

Can I bring Anker portable chargers on a plane?
Yes, the vast majority of Anker portable chargers are allowed in carry-on luggage. However, always check with your specific airline before flying, as policies can vary slightly between carriers and countries.
How many times can a portable charger charge my phone on a long flight?
It depends on the capacity of the power bank and your phone’s battery size. As a general rule, you can estimate the number of charges by multiplying the power bank’s mAh capacity by 0.65 (to account for energy conversion loss) and dividing by your phone’s battery size.
Should I charge my Anker power bank before a long flight?
Absolutely. We always recommend fully charging your power bank the night before travel to make sure you start your flight with maximum capacity.
