A dead phone abroad means no maps, no boarding pass and no ride-hailing app. A good power bank is one of the most important travel accessories, and the Anker Nano Power Bank (10,000mAh, 30W, built-in USB-C cable) fixes the most annoying part: forgetting the cable.

Why It’s Perfect for Travel
The built-in USB-C cable is the star feature. It sits along the side of the power bank and doubles as a lanyard, so you can clip it to a backpack or carry it by the loop. With most iPhones (iPhone 15 and newer) and Android phones using USB-C, one power bank covers your phone, earbuds and many tablets.
At 30W, it can fast-charge recent phones and even top up small laptops like the MacBook Air in an emergency. You can charge two or three devices at once using the other ports.
Airline Rules
At 10,000mAh (roughly 36Wh), it’s well below the common 100Wh airline limit for power banks. Remember that power banks must go in carry-on luggage, never checked bags, and some airlines now limit using them during the flight.
Real-World Capacity
Expect about 1.5–2 full charges for a typical modern smartphone. Some energy is always lost in conversion, so no power bank delivers its full rated capacity to your phone.
Pros
- Built-in cable, so you never forget one
- 30W fast charging
- Pocket-sized with a useful display
- Charges multiple devices
- Airline-friendly capacity
Cons
- Built-in cable is short
- Heavier than ultra-slim 5,000mAh options
- Not enough capacity to fully charge a laptop
Verdict
For most travelers, this Anker Nano is close to the ideal everyday power bank: compact, fast and impossible to strand without a cable.
