Power Banks: USB-C PD, Qi2, and Airplane Rules — The Quick Guide

Modern power banks combine USB-C Power Delivery (PD) wired charging and
Qi wireless charging . With Qi2 , magnetic charging reaches 15W on the
compatible devices, thanks to precise alignment for better performance. For recent iPhones
and many accessories, it is the most practical solution for everyday use.

On the wired side, USB-C PD 20–33 W covers the vast majority of smartphones; the models
45–65 W accelerates tablets and some consoles; and 100–140 W blocks
are aimed more at demanding uses (PC/monitor/video editors). The PD 3.1 standard even extends the power
theoretical up to 240W when hardware and cable are compatible.

To travel by plane , remember the simple rule: ≤ 100 Wh = authorized in the cabin.
Between 101 and 160 Wh , company approval is required (usually
2 units max ). Beyond 160 Wh , it is prohibited for passengers.
On our datasheets, we display the capacity in Wh in addition to the mAh so that
you know immediately if your power bank is “OK cabin”.

Finally, if you are unsure, think about uses: a 10,000–20,000 mAh model covers the majority of
busy days; the mini 1,500–5,000 mAh batteries are used as a backup; the solar ones
provide additional energy outdoors; and energy stations (AC + USB-C)
take it to the next level for camping or emergency.

Frequently Asked Questions

What is Qi2?

The next generation of wireless charging with magnetic alignment and up to 15W
on compatible devices. Ideal for iPhone 15/16 and Qi2 compatible accessories.

How much power does my smartphone need?

Most already win with USB-C PD 20–33 W. Beyond that (45–140 W), we aim for heavier uses
(tablets, consoles, sometimes laptops).

Can I take my power bank on a plane?

Yes if ≤ 100 Wh in cabin. 101–160 Wh : airline approval (often 2 max).
>160 Wh : prohibited. We always indicate the Wh on the product sheets.

Does “solar” really recharge?

On power banks, the integrated panel serves as a backup . To recharge faster, choose a
USB-C PD input with a suitable charger and use the sun to top up.
