Glossary
Max. power (USB)
The maximum energy level that the charger can deliver to a specific port. This parameter determines the charging speed of the gadget and the ability to power high-demand devices, such as laptops.
It's important to note that when using multiple ports simultaneously, the total power of the unit is often distributed among them, reducing the speed for each individual port. For example, a 65W adapter can deliver full power to a single laptop, but when a second smartphone is connected, it will share the resources, limiting the main port to, say, 45W. To achieve the stated maximum, it's necessary to use a quality cable, and the device being charged must support the corresponding charging power.

Cable length
The length of the cable supplied with or included with the charger. For wireless models, the length of the power cable of the charger itself is indicated here, for wired models, the length of the cord for charging gadgets
Anyway, a longer cable gives more freedom of movement, but it creates inconvenience for short distances. Also note that charging is supposed to be used in the immediate vicinity of sockets, so wires longer than 2 m are practically not found among such devices. A length of more than 1.5 m is considered significant, from 1 to 1.5 m — medium, from 0.5 to 1 m — small, and in some models there are wires shorter than 0.5 m.
