Digital specialist Jean-Baptiste Nicolet explained how to choose a universal USB-C charger for electronic devices during an appearance on French morning news show Bonjour ! La Matinale TF1.
Nicolet noted that adopting a universal charger allows consumers to limit the number of power adapters kept at home. The USB-C port is now compatible with most current electronic devices, including smartphones, tablets, and charging cases for wireless earphones.
According to Nicolet, new smartphone generations produced since 2022 and 2023 all feature the USB-C format. In addition, European regulations mandating USB-C charging ports for laptop computers have applied since April 28, 2026.
The European Union rules on universal charging standards were enacted to reduce electronic waste across member states and simplify consumer tech accessories. TF1 is France's leading nationwide private television network, broadcasting news and magazine programs to millions of viewers daily.
High-capacity multi-port charging units
Nicolet detailed that the core objective for modern consumers is to use a single cable and a single charger for all their products. This shift comes as tech manufacturers have routinely sold electronic devices without bundled chargers for several years, making careful selection of a replacement charger essential.
During the television broadcast, the columnist showcased an imposing 140-watt charger designed to power high-demand devices. The unit is capable of connecting a laptop computer, a smartwatch, wireless headphones, and a smartphone simultaneously using four built-in ports.
The 140-watt charger features an integrated display screen that reveals real-time charging metrics. Users can view the exact wattage being delivered, the number of connected devices, and the heat emitted during operation. While the charger costs 70 euros, Nicolet pointed out that it replaces four separate power adapters.
Addressing safety concerns regarding high electrical output, Nicolet clarified that a 140-watt charger will not fry connected devices. New chargers and modern smartphones incorporate a standardized protocol known as USB Power Delivery, or USB PD.
Nicolet explained that USB Power Delivery adapts energy output dynamically based on what each device requires. If a smartphone only needs 25 watts, the charger supplies 25 watts, whereas a laptop needing 45 watts receives 45 watts.
USB Power Delivery is an open industry protocol developed by the USB Implementers Forum. It allows devices to negotiate power levels safely over USB-C connections, ensuring fast charging without overloading delicate circuitry.
Compact chargers and universal cables
For users seeking a more portable setup, Nicolet presented a compact 45-watt universal charger. This smaller unit is designed to charge one product at a time while still providing a small monitoring screen to track power delivery.
Nicolet detailed that even with the smaller 45-watt charger, consumers can successfully power a smartphone, tablet, computer, or smartwatch. The compact model offers a lower price point, retailing for 30 euros.
To ensure optimal charging performance, Nicolet stressed the importance of selecting a cable with the appropriate power specification. He noted that cables rated for 60 watts and 140 watts are widely available on the market.
High-capacity cables capable of handling maximum power output can cost around 50 euros, but their universal design ensures compatibility across multiple devices. Nicolet concluded that the ultimate goal for consumers today is to rely on just one charger and one cable.
