How we chose
The ideal travel battery is not necessarily the biggest. It is the one that matches your use, without weighing down your bag. To build this selection, we weighed five criteria:
- Usable capacity: enough energy to last the day (or the week).
- Weight-to-runtime ratio: essential when you carry your bag.
- Fast charging (USB-C Power Delivery) to avoid wasting time.
- Ruggedness and reliability of the brand.
- Airline compliance: all stay under 100 Wh, so they are cabin-allowed.
The result: five power banks for five traveller profiles. It is up to you to find yours.
1. The most versatile: INIU 20,000 mAh
If you had to pick just one, this would probably be it. With its 20,000 mAh, the INIU has enough to recharge a smartphone three to four times, easily enough for a weekend or a long journey. It packs several ports, comfortable fast charging and a small screen showing the remaining level.
It is the traveller's Swiss Army knife: capacious enough not to think about it, still compact enough for the backpack, and at a very reasonable price. The default choice for most uses.
2. The hiker's ultralight: Nitecore NB10000
Hikers, trekkers, bivouac fans: this one is for you. The Nitecore NB10000 is a feat of lightness thanks to its carbon-fibre casing, with a feather weight that disappears in the bag. Its 10,000 mAh is enough to recharge a phone once or twice, the essentials to stay reachable and keep the GPS running out in nature.
It is the battery I personally take on treks: when every gram counts, this weight-to-runtime ratio is unbeatable. Rugged and reliable, it handles tough conditions.
3. The pocket backup: Ugreen Nexode Mini 5,000 mAh
For those who just want a safety net in their pocket, the Ugreen Nexode Mini works wonders. Tiny and light, it slips in anywhere and gives a smartphone a full backup charge. Ideal for a day out, a festival or an evening in town, when you want to travel ultralight.
Despite its size, it benefits from modern fast charging: enough to quickly top up when the phone's battery is flirting with the red.
4. The wireless champion: Anker MagGo
Got a recent iPhone? The Anker MagGo clips magnetically onto the back of your phone and charges it without a single cable, MagSafe style. A serious convenience on the move: you keep using your phone while it charges, with no dangling cord.
Its 10,000 mAh is a perfect fit for a busy day. Wireless charging is a little less efficient than a cable, but the gain in convenience is well worth that small trade-off for urban use.
5. The powerhouse for laptops: Anker 737 Power Bank
For digital nomads who travel with their laptop, you need serious muscle. With its 24,000 mAh and high output power in USB-C Power Delivery, the Anker 737 charges not only phones and tablets, but most laptops too. Its screen shows exactly the power and remaining runtime.
Bigger and heavier than the others, that is the price of this high-end versatility. It stays under the 100 Wh mark, though, so it is cabin-allowed. The perfect companion for working on the move.
Recap and travel tips
In short: the INIU for versatility, the Nitecore for trekking, the Ugreen Mini for ultralight backup, the Anker MagGo for wireless convenience, and the Anker 737 to charge a laptop. There is bound to be a model for the way you travel.
Two reflexes before boarding: check that your battery stays under 100 Wh (all of these do) and keep it in the cabin. All the details are in our guide lithium batteries on planes.
