Why buy a power bank in the first place
The question of whether it’s worth buying a power bank comes up often. Do we really need an additional battery if we can carry a charger in our bag or car? In practice — yes. A trip outdoors, a several‑hour flight, a day full of meetings, or a weekend festival is enough to appreciate having an extra reserve of power in your pocket.
Power banks today are no longer just gadgets. They are practical tools capable of charging a phone, tablet, headphones, smartwatch, or camera — often even several devices at the same time.
Thanks to fast‑charging technologies such as USB Power Delivery and Quick Charge, modern power banks can charge devices just as quickly as standard wall chargers.
What should you consider when choosing a power bank?
A good power bank should match the way you use your electronic devices. It’s worth paying attention to a few key parameters:
-
Capacity (mAh/Wh) – the higher it is, the more phone charges you get. A standard 10,000 mAh is enough for 2 full cycles, while 20,000 mAh provides a reliable energy reserve for a weekend or an intercontinental flight. Keep in mind that 100 Wh is the maximum capacity allowed on board an airplane.
-
Power output and fast‑charging standards – the best models support USB Power Delivery and Quick Charge 3.0/4.0, allowing you to charge an iPhone, Samsung, or even a laptop faster.
-
USB and USB‑C ports – the number and type of ports determine how many devices you can charge at the same time.
-
Safety and build quality – certifications, protection against overheating, overvoltage, and short circuits.
One standout in this category is the Forcell F‑Energy P20K2 – a power bank with a capacity of 20,000 mAh and 22.5 W output.
With four ports (3×USB‑A and 1×USB‑C), it allows you to charge several devices at once, supports USB Power Delivery, and stays within the 77 Wh limit, making it suitable for air travel.
Powerbank do iPhone 17 – a właściwie do iPhone Air
The new iPhone Air from the 17 series impresses with its design and lightness, but it has one drawback — a smaller battery. Apple has even released a dedicated MagSafe battery for the iPhone Air, the magnetic MagSafe Battery Pack, but its price — around 500 PLN — quickly cools the enthusiasm.
Is it worth it? Not really. This MagSafe battery designed only for the iPhone Air works exclusively with one model and offers a modest capacity of around 3149 mAh. Yes, it looks elegant, but it won’t fully charge the iPhone and doesn’t support fast charging above 12 W.
There are far more universal solutions on the market — such as the Forcell F‑Energy F5k8 (MagSafe, 5000 mAh).
It’s a compact MagSafe power bank that magnetically attaches to the back of the iPhone Air, 17, or 16. Thanks to 15 W wireless charging and a USB‑C Power Delivery port, it can charge an iPhone much faster than Apple’s original battery pack. It also features a clear LED display and a slim aluminum‑glass housing.
If you value convenience, fast wireless charging, and elegant design, the F5k8 is an alternative that costs significantly less than Apple’s battery pack while offering more functionality.
Power bank for air travel — which one can you take on board
Many travelers wonder whether you can take a power bank on a plane. The answer is: yes, but under certain conditions.
The rules are defined by the IATA and EASA organizations, and most airlines follow the same guidelines.
The most important rules are simple:
-
A power bank must always be carried in hand luggage, never in checked baggage.
-
The device cannot exceed 100 Wh — this corresponds to approx. 27,000 mAh at 3.7 V.
-
Models with a capacity above 100 Wh but below 160 Wh require airline approval.
-
A power bank should be protected against accidental activation and easily accessible during security checks.
That’s why it’s best to choose models with high capacity without exceeding the limits, such as the mentioned Forcell F‑Energy P20K2 (77 Wh) or Forcell S10K1 (10,000 mAh) — lightweight, safe, and approved for transport in hand luggage.
MagSafe wireless power banks — convenience on the go
During short flights or business trips, MagSafe wireless power banks turn out to be especially convenient. They don’t require cables, and the magnetic attachment ensures that the phone starts charging automatically as soon as it’s placed on the power bank.
In this category, besides the previously mentioned Forcell F5k8, it’s worth considering the VEGER 10,000 mAh MagOn (VP1151/W1151) — a model with inductive charging, compatible with MagSafe and supporting PD and QC 3.0. It enables fast wireless charging at 20 W, and thanks to its compact housing, it fits perfectly in a pocket or bag.
It’s a practical alternative for those who value minimalism and prefer to avoid tangled cables while traveling.
