Five current power banks at or under €100, compared on real capacity, charging speed, magnetic charging, weight and the airline rules in Europe.
For one power bank that charges almost any phone fast and fits in a pocket, buy the INIU Pocket Rocket P50 (€39.99). iPhone 16 and 17 owners who want to clip a battery on without a cable should get the UGREEN MagFlow Qi2 25W (€89.99). If you also carry a USB-C laptop, the UGREEN Nexode 20000mAh 165W (€99.99) is the only pick here that can charge one properly.
How we picked. Each power bank went on sale in Europe on or after 9 November 2024 and has no successor on sale yet. Each has an official euro price of €100 or less on its maker’s European store, a maker spec page, and at least one review from an established outlet. We covered four uses: pocket, everyday, magnetic and laptop. Left out: the Anker Power Bank (20K, 87W) and the Anker Zolo 10K, both launched in 2024; UGREEN’s MagFlow Pro, over the cap at €129.99; UGREEN’s MagFlow Air 25W, too new for full reviews; and Samsung’s own packs, launched between 2022 and 2024.
This comparison is based on manufacturer specifications and cited independent reviews. Tech & Roll did not test these power banks.

Capacity: what reaches your phone
The mAh number on the box measures the battery cells, not what comes out of the port. Some energy is lost converting the cells’ voltage to USB voltage, and more as heat. UGREEN rates the Nexode’s 20,000mAh at 11,600mAh of output and the MagFlow’s 10,000mAh at 5,600mAh. Anker’s guide says a typical 10,000mAh bank delivers about 5,500 to 6,500mAh.
The Anker 5K Slim took an iPhone 16 Pro from empty to 77% (Macworld). The MagFlow gave one full iPhone 16 Pro charge plus 44%, and the Anker 10K 45W managed about two iPhone 15 charges. The Gadgeteer measured about 60Wh out of the Nexode’s 72Wh.
So a 5,000mAh bank is a top-up and a 10,000mAh bank gives one or two phone charges.
Fast charging: match the bank to your phone
Most phones charge fastest from USB-C Power Delivery (PD), which four of the five banks name in their specs. Samsung phones also need PPS (Programmable Power Supply). Samsung’s support pages say Super Fast Charging may not work without it, whatever the wattage. Four of the five banks list PPS; Anker does not say whether the 5K Slim has it.
Reviewed charged a Galaxy S26 Ultra from 25% to full in 43 minutes on the INIU P50. TechRadar took a Galaxy S24 FE from empty to full in about 80 minutes on the Anker 10K 45W.
The 45W on the INIU and the Anker 10K applies to one device only. Plug in a second and the INIU drops to 15W in total. Only the Nexode is built to charge two devices fast at once: 100W plus 65W.
Magnetic charging: Qi2 or Qi2.2
Qi2 is the magnetic wireless standard that works like Apple’s MagSafe. The newer Qi2.2 raises the speed from 15W to 25W, but only on phones that support it. Macworld says only iPhone 16 and 17 models running iOS 26 or later get 25W from the MagFlow, and its iPhone 15 Pro stayed at 15W. On an iPhone 16 Pro, Macworld measured 0 to 50% in 32 to 33 minutes.
The Anker 5K Slim uses 15W Qi2. Anker lists it for iPhone 12 to 17 and the Pixel 10 series, but not for the iPhone 16e, the 12 mini, the 13 mini or the iPhone SE.
Laptops and weight
Only the Nexode has the output for a laptop: 100W from its cable or USB-C port. TechRadar charged a ThinkPad T14s from 5% to 90% before the bank ran empty, and Mighty Gadget took a 13-inch MacBook Pro from 20% to 80% in about 45 minutes, but the Nexode weighs 535g. The Anker 10K 45W can top up a MacBook Air (Macworld added 31% in 30 minutes), but Anker itself says it is not meant for laptops.
Can I take it on a plane in Europe?
Yes, in your hand luggage. EASA, the European Union Aviation Safety Agency, treats power banks as spare batteries. They are banned from checked luggage, and EASA advises keeping them on you or in your cabin bag. Banks under 100Wh need no approval, and 100 to 160Wh needs the airline’s approval. All five picks are well under 100Wh.
Since 27 March 2026, the dangerous-goods rules of ICAO, the UN aviation body, have limited each passenger to two power banks and banned recharging them on board. Airlines in Europe apply these rules. EASA also advises against using a power bank to charge your phone during the flight. Some airlines are stricter. Lufthansa Group airlines, for example, have banned using power banks on board since 15 January 2026, and do not allow them in the overhead locker. Rules differ by airline, so check yours before you fly.

Verdict
Best overall and best on a budget
INIU Pocket Rocket P50
Fast USB-C, PPS and a three-year warranty in the smallest wired body here, but it recharges slowly.
Official price €39.99 (checked 9 Nov 2026).
Best for travelling light with a cable

The cable is always attached and the screen shows live watts.
Official price €52.99 (checked 9 Nov 2026).
Best for iPhone users
UGREEN MagFlow Qi2 25W

It is the only pick that can charge a laptop properly, but it weighs 535g.
Official price €99.99 (checked 9 Nov 2026).
FAQ
Do I need a special cable?
Sometimes. T3 notes that the INIU’s included cable is rated 3A, so the full 45W needs a 5A cable. Samsung bases its 45W Super Fast Charging 2.0 on a 5A cable, although it says the Galaxy S25 and later get it with their own 3A cable.
Will a Qi2 power bank work with an Android phone?
It attaches magnetically only to phones with Qi2 magnets, such as the Pixel 10 series (per Anker). The MagFlow also charges older Qi phones in its 5W and 7.5W modes, but they will not stay attached.
Can I charge my power bank on the plane?
No. ICAO rules have banned recharging power banks on board since 27 March 2026. EASA also advises against using one to charge your phone during the flight.
