Anker Prime Power Bank (26K, 300W): most power for laptop users
According to Anker, it holds 26,250mAh (99.75Wh), just under the 100Wh line. It offers 300W total across two USB-C ports and one USB-A, and 140W from a single USB-C port, enough for power-hungry laptops. Anker also says it can recharge at up to 250W using both USB-C ports, and it has a smart display with app control.
Pros
- About as much capacity as you can carry without airline approval
- 140W single-port output for big laptops
- Very fast recharging if you have a high-wattage charger
Cons
- At 99.75Wh it's right at the edge, so make sure the label stays legible
- Overkill if you only charge a phone
Who it's for: laptop-first travellers and creators who need serious power between sockets.
UGREEN Nexode Power Bank 20000mAh 130W: the balanced pick
UGREEN lists it at 20,000mAh / 72Wh, comfortably under the limit. It has two USB-C ports (100W + 30W) and one USB-A (22.5W), a TFT display showing live power, and 476g in its spec table. One USB-C port can run a laptop while the second tops up a phone.
Pros
- Plenty of margin under 100Wh
- A 100W port covers most laptops
- The display shows exactly what each port is drawing
Cons
- 65W max input, so recharging is slower than the Anker Prime
- Heavier than phone-only banks
Who it's for: most travellers carrying a laptop and a phone.

Anker Laptop Power Bank (25K, 165W): built-in cables
Anker's own collection page lists this model at 25,000mAh / 90Wh and describes it as approved for air travel. Its main selling point is built-in and retractable cables, so there's one fewer thing to forget in a hotel room.
Pros
- Comfortably under 100Wh
- Built-in cables mean less to pack
Cons
- Built-in cables can't be swapped if they wear out
- Check the product page for per-port output and weight
Who it's for: minimalists who hate cable clutter.

What to look for in a flying power bank
- A printed Wh or mAh rating. Some airlines, Emirates among them, require capacity information on the bank.
- USB-C PD output that matches your laptop's charger wattage.
- Pass-through charging, if you want to charge the bank and your phone overnight from one socket. Check the product page.
- Realistic capacity. Anker notes that 30–45% energy loss in conversion is normal, so a bank delivers less than its label figure to your device.
FAQ
Are these allowed on Emirates?
Emirates allows one power bank under 100Wh and bans using it on board. All three banks here are under 100Wh by their makers' figures, but you can bring only one on Emirates.
Can I bring two of them?
ICAO caps it at two power banks per person, but airlines like Emirates and Southwest allow only one. Check your airline.
Is 99.75Wh really allowed?
It's under 100Wh, which the FAA and IATA treat as allowed without approval. Keep the label readable.
Will it charge my laptop?
Only if the bank's USB-C output meets your laptop's needs. Compare your laptop charger's wattage with the port output in the table.
Which is lightest?
UGREEN publishes 476g for the Nexode 20000mAh. Check Anker's product pages for its models' weights.
Conclusion
For laptop power right at the limit, go with the Anker Prime 26K. For a sensible all-rounder, the UGREEN Nexode 20000mAh is the easy choice. If you want built-in cables, look at the Anker 25K. Whichever you pick, it goes in your carry-on, and check your airline's quantity limit.
