Best Travel Power Banks for 2025

Looking for the best power bank for international travel? From pocket-sized backups to powerful multi-device chargers, we’ve selected the top three models that combine performance, portability, and smart features to keep you powered up wherever you go.

1. Anker MagGo Power Bank (5K, Slim)

If you're flying across time zones or hopping between cities, keeping your phone charged without fumbling for cables is a win. The Anker MagGo Power Bank (5K, Slim) gets it right with a compact build and seamless MagSafe support that locks into place on the back of your iPhone. It's designed for short-haul power boosts, not full-day charging marathons—but for most travelers, that’s exactly the point.

With 15W wireless output and 20W wired USB-C support, it delivers fast, reliable charging in the moments that matter—like during a gate change or mid-Uber ride. It also pairs with the Anker app to monitor battery temperature and status in real-time, which is a nice bonus if you're charging in warm climates or tightly packed bags.

At 5,000mAh, it's not the biggest battery out there, but it hits the sweet spot for portability and function. If your travel style is light, fast, and efficient, the MagGo 5K earns its place as one of the best power bank for international travel in 2025.

Thanks to 15W wireless charging, it quickly charges your phone—like taking an iPhone 15 Pro from 0 to 50% in about 50 minutes—without needing cables. If you prefer wired charging, the 30W USB-C port is perfect for getting your devices charged fast, whether you're on a plane or running to your next meeting.

The sleek matte finish and aerogel insulation keep the device cool and comfortable to hold, even when in use. With enough juice to charge your phone almost twice, this power bank is a solid choice for anyone who’s always on the move.

3. Anker Nano Power Bank (10K, 45W, Built-in Retractable USB-C Cable)

What makes it ideal for travel is its built-in retractable USB-C cable, meaning you don’t have to worry about tangled cords or remembering an extra charger. Plus, the 45W fast charging ensures your devices get powered up quickly—whether you're on the go in an airport lounge or between meetings in a new city.

With two USB-C and one USB-A port, you can charge multiple devices at once, all while the power bank stays conveniently attached to your bag with the included lanyard. This is one power bank that won’t weigh you down, making it a must-have for any frequent traveler.

Key Factors to Consider When Looking for a Travel Power Bank

Selecting the best travel power bank isn’t just about capacity; it’s about matching features to your travel habits.

Start with battery size—think realistically about how often you’ll recharge devices away from outlets. If you take frequent long-haul flights, 10,000mAh or higher is smart, but for weekend trips, a slim 5,000mAh model may be more practical.

Pay attention to charging speed. Quick Charge or Power Delivery (PD) ports ensure you aren’t stuck waiting hours for a phone or tablet to refill. Check included cables—some models have built-in or retractable connections, reducing clutter and risk of leaving important accessories behind. If you’re an iPhone user, MagSafe compatibility is a game changer for convenience, while Android or laptop users should focus on powerful USB-C output.

Don’t forget about weight and shape. The best power bank for international travel fits easily in a carry-on or jeans pocket without dragging you down. Features like an LCD display, smart safety tech, or a built-in phone stand can also make a big difference. Finally, always ensure your chosen power bank is TSA compliant—a requirement, not just a suggestion, for all US travelers.

TSA Rules for Flying with Power Banks in the U.S.

If you’re planning to bring the best travel power banks on your next flight, you need to know the TSA’s rules. These regulations are designed to minimize fire risk and ensure safety onboard. Here’s a concise overview of what’s allowed, what requires permission, and how to stay compliant every time you pack your portable charger.

1.Carry‑On Only

• Power banks must go in your carry‑on luggage.
• Checked baggage is off‑limits due to fire‑hazard concerns.

2.Capacity Limits

• Under 100 Wh: Permitted without approval.
• 100–160 Wh: Allowed only with airline authorization.
• Above 160 Wh: Strictly prohibited on any flight.

3.Airline‑Specific Variations

• Policies can differ—always verify your carrier’s lithium‑battery limits before you fly.
• Most airlines mirror TSA guidelines but may cap the number of spare units.

4.Device Power‑On Requirement

• Your power bank (and any lithium‑battery device) must power on during security screening.
• Carry a charging cable so you can demonstrate functionality if asked.

5.Overall Battery‑Count Cap

• Passengers are generally limited to carrying batteries for 15–20 devices (phones, laptops, earbuds, camera packs, etc.).
• If you need more, distribute them across your travel companions’ carry‑ons.

Practical Tips to Extend the Life of Your Travel Power Bank

In addition, follow these best practices to get every mAh out of your pack.

• Use the right cables: Cheap knock‑offs can slow charging and degrade cells. Stick to manufacturer‑rated cables.
• Avoid extreme temperatures: Don’t leave your power bank in a scorching car or freezing overhead bin. Optimal range is 32–77°F (0–25°C).
• Charge regularly: If you store your pack for long layovers, keep it at about 50 percent capacity and top it up every three months.
• Turn off pass‑through charging: Some banks let you charge devices while recharging the bank itself, but this stresses the battery. It’s best to charge one at a time.
• Watch for firmware updates: Many power banks offer firmware updates that improve performance and safety. Keep an eye out for any available updates to ensure your device runs smoothly.

Using these steps and choosing the best travel power bank for your needs will help you avoid dead batteries and equipment failure on crucial trips.
