USB-C is a connector and interface ecosystem rather than a single performance tier. Its specifications span charging power, data transfer, display protocols and regulation, while device-level results depend on the host, cable, charger and connected equipment.
Key USB-C Statistics
The most useful headline figures cover capability, regulation, consumer scale and measured or modelled outcomes:
- 240 W is the maximum USB Power Delivery level defined by USB PD 3.1 for the USB-C ecosystem in the 2021 specification update.
- 100 W at 20 V and 5 A was the cited pre-PD 3.1 USB-C PD limit before the 2021 update.
- USB4 Version 2.0 supports up to 80 Gbps over USB-C in the 2022 announcement.
- Certain USB4 display applications can reach 120 Gbps in one direction and 40 Gbps in the other under the optional asymmetric configuration announced in 2022.
- The European Union common-charger rules cover 12 device categories from 28 December 2024.
- EU laptop requirements begin on 28 April 2026, adding one device category to the common-charger rules.
- EU consumers buy an estimated 160 million mobile phones each year, according to a 2022 Council infographic.
- EU consumers buy an estimated 260 million other portable electronic devices each year, according to the same 2022 Council estimate.
- 38% of surveyed Europeans reported charging problems because compatible chargers were unavailable, in the Council infographic survey.
- The common-charger measures are estimated to save at least €250 million per year in unnecessary EU charger purchases.
- The Commission estimates 980 tonnes of electronic waste could be avoided each year under the EU common-charger measures.
- EU discarded and unused charger waste was estimated at 11,612 tonnes in 2020, according to the Council series.
- More than 400 million external power supplies are sold in the EU annually, a broader category than USB-C chargers.
- The Commission forecasts a 3% annual reduction in external-power-supply lifecycle energy consumption by 2035 under its revised EPS rules.
- The Commission forecasts a 9% reduction in related greenhouse-gas emissions by 2035 under those EPS rules.
- Apple’s iPhone 15 USB-C port supports USB 2 data transfer up to 480 Mb/s, according to its technical specifications.
- The iPhone 15 can reach 50% charge in around 30 minutes with a 20 W or higher adapter, under Apple’s test claim.

USB-C Power Delivery and Charging Capacity
USB Power Delivery 3.1 expanded the specified ceiling for USB-C charging. The USB-IF describes the capability as a maximum, so it should not be read as the ordinary charging rate of every USB-C product.
| USB-C Power Delivery measure | Value | Period and scope |
|---|---|---|
| Earlier cited PD solution | 100 W at 20 V and 5 A | Before the 2021 PD 3.1 update; USB-C Power Delivery |
| New fixed-voltage option | 28 V / 140 W | USB PD 3.1; specified option |
| New fixed-voltage option | 36 V / 180 W | USB PD 3.1; specified option |
| New fixed-voltage option | 48 V / 240 W | USB PD 3.1; specified option |
USB PD 3.1 also supports adjustable voltage from above 15 V up to the charger’s available fixed-voltage maximum. USB Type-C Release 2.1 defines cable requirements for 240 W operation, making the cable part of the capability chain rather than a passive guarantee of maximum power.

USB-C Data Speeds and Display Performance
USB4 Version 2.0 raised the headline USB-C data rate to 80 Gbps while retaining 20 Gbps and 40 Gbps USB4 options. The 2022 USB-IF announcement identifies PAM3 physical-layer encoding, new active cables for 80 Gbps and qualifying existing 40 Gbps passive cables that can support the higher operation.
| USB4 over USB-C measure | Value | Scope |
|---|---|---|
| Existing USB4 option | 20 Gbps | USB4 ecosystem |
| Existing USB4 option | 40 Gbps | USB4 ecosystem |
| USB4 Version 2.0 headline rate | 80 Gbps | Appropriate host, cable and device required |
| Optional display asymmetry | 120 Gbps one way / 40 Gbps the other | Certain display applications |
USB4 Enhanced SuperSpeed data tunneling can exceed 20 Gbps, and USB4 aligns with DisplayPort 2.1 and PCI Express 4. These are architecture and protocol capabilities, not guarantees that every USB-C connector supports USB4, those display modes or those speeds; USB4 is described as backward-compatible with previous USB versions at the best mutual capability.

EU USB-C Adoption and Covered Devices
The European Union’s common-charger rules give USB-C a regulatory adoption pathway, but the category count is not a market penetration rate. From 28 December 2024, the Commission lists 12 covered categories: phones, tablets, cameras, headphones, headsets, speakers, consoles, e-readers, earbuds, keyboards, mice and navigation systems.
The rules extend to laptops on 28 April 2026. That date is an application date for one additional category, not a measurement of how many laptops already use USB-C.
The Council’s 2022 infographic estimated annual EU purchases at 160 million mobile phones and 260 million other portable electronic devices. It reported the combined annual total as 420 million devices, while noting that the broader portable-device category is not identical to the set covered by the directive.
The Commission estimates that the measures will reduce electronic waste by 980 tonnes per year and save at least €250 million per year in unnecessary charger purchases. Both are policy estimates rather than measured post-implementation outcomes.

USB-C Consumer Costs and Charging Access
The Council infographic places charger interoperability in a consumer context. In its survey, 38% of people reported charging problems because compatible chargers were unavailable; the supplied excerpt does not provide the underlying survey’s full denominator or fieldwork details.
| EU consumer or market measure | Figure | Measurement context |
|---|---|---|
| Mobile phones purchased annually | 160 million | Council estimate cited in 2022 |
| Other portable electronics purchased annually | 260 million | Council estimate cited in 2022 |
| People reporting compatible-charger problems | 38% | Council infographic survey |
| Unnecessary charger-purchase savings | At least €250 million/year | Commission policy estimate |
| Charger-purchase savings | €250 million/year | Council infographic estimate |
The two charger-savings figures are separately stated versions of the policy estimate: the Commission uses “at least €250 million,” while the Council infographic reports €250 million annually. They should not be treated as two different savings streams.
The Commission also expects the EU’s external-power-supply rules to make an additional 35%–40% of the EPS market interoperable by 2035, beyond the approximately 50% already assumed interoperable. These are expectations for the broader external-power-supply market, not observed USB-C adoption rates.

USB-C Environmental Statistics and Forecasts
The Council estimates that discarded and unused charger waste in the EU was 11,612 tonnes in 2020, 11,601 tonnes in 2022 and 11,849 tonnes in 2024. Its series projects 12,160 tonnes in 2026 and 13,305 tonnes in 2028; the latter two are projected estimates, not observed post-rule results.
| Year | Estimated or projected discarded and unused charger waste | Scope |
|---|---|---|
| 2020 | 11,612 tonnes | EU estimate |
| 2022 | 11,601 tonnes | EU estimate |
| 2024 | 11,849 tonnes | EU estimate |
| 2026 | 12,160 tonnes | EU projected estimate |
| 2028 | 13,305 tonnes | EU projected estimate |
These charger-waste figures are different from the Commission’s separate 980-tonne annual reduction estimate and should not be merged into one observed trend. The Council also estimates indirect greenhouse-gas reductions of approximately 180 ktCO2e per year from the common-charger measures.
For wider context, the Council comparison reports regional e-waste generation of 16.2 kg per person in Europe, 16.1 kg in Oceania, 13.3 kg in America, 5.6 kg in Asia and 2.5 kg in Africa. These are regional e-waste figures, not USB-C-specific waste measurements.
More than 400 million external power supplies are sold in the EU each year. For 2035, the Commission forecasts that revised EPS rules could reduce lifecycle energy consumption by around 3%, related greenhouse-gas emissions by 9%, related pollutant emissions by around 13% and consumer expenditure by around €100 million annually; it equates the energy saving to the annual energy use of around 140,000 electric cars.

USB-C Device-Use Outcomes
Apple’s iPhone 15 illustrates why a USB-C connector should not be treated as a universal performance label. Its technical specification lists charging, DisplayPort and USB 2 functions on the same connector, with USB 2 data transfer up to 480 Mb/s.
The iPhone 15 supports DisplayPort video output up to 4K at 60 Hz, and Apple’s launch specification says a USB-C Digital AV Multiport Adapter can provide 4K HDR video at 60 frames per second. Through that cited adapter configuration, the phone can simultaneously connect an HDMI display, a standard USB device and a USB-C charging cable.
Apple also claims that the iPhone 15 can reach 50% charge in around 30 minutes with a 20 W or higher adapter. The claim is model-specific and varies with conditions and adapter; it does not describe all USB-C phones.
| iPhone 15 measure | Apple-listed value | Scope |
|---|---|---|
| Local video playback | Up to 20 hours | Controlled-use estimate |
| Streamed video playback | Up to 16 hours | Controlled-use estimate |
| Audio playback | Up to 80 hours | Controlled-use estimate |
| MagSafe wireless charging | Up to 15 W | Separate from wired USB-C port |
| Qi2 wireless charging | Up to 15 W | Separate from wired USB-C port |
| Standard Qi wireless charging | Up to 7.5 W | Separate from wired USB-C port |
