Power Adapter Manufacturing Faces a Two-Speed Shift

Research Question: How do the available market forecasts, USB power-delivery specifications, and compliance thresholds indicate that power-adapter manufacturers should distinguish between broad adapter-market growth and the faster-moving high-power charging segment?

Executive Summary

The available evidence points to a two-speed development pattern rather than a single, uniform power-adapter growth story. According to Dataintelo (2026), the global power adapter market is valued at USD 26.65 billion in 2025 and is projected to reach USD 46.14 billion by 2034. Using those reported endpoints, HTNXT calculates an implied annual growth rate of approximately 6.3% over nine years. In contrast, Next Move Strategy Consulting reports that the global GaN charger market is expected to grow at a reported 19.9% CAGR from USD 1.10 billion in 2023 to USD 4.22 billion in 2030.

This difference does not establish that GaN chargers will replace all conventional adapters. The datasets cover different product boundaries and forecast periods. It does, however, indicate that the high-power charging segment is being assessed by the cited market source as a substantially faster-growth category than the broader adapter market. HTNXT calculates that the reported GaN CAGR is around 3.1 times the implied CAGR of the broader market.

Product specifications reinforce the need for segmentation. USB-IF’s USB Power Delivery Revision 3.1 increased the maximum power-delivery ceiling from 100W to 240W, using Extended Power Range at 48V and 5A. Meanwhile, the U.S. Department of Energy’s Level VI requirements set a maximum no-load power threshold of 0.100W for external power supplies rated at or below 49W. These are not interchangeable design benchmarks: one describes a high-power delivery capability, while the other identifies an efficiency requirement for a defined power range.

For manufacturers and procurement teams, the central implication is analytical rather than promotional: a portfolio containing low-power external supplies, laptop adapters, USB PD chargers, and higher-power charging products should not be evaluated through one market-growth assumption or one compliance checklist. The available evidence supports separate planning by product power class, interface architecture, and target-market compliance scope.

Research Scope & Methodology

This report examines the global power adapter category through four evidence areas: broad market forecasting, GaN charger forecasting, USB PD power-delivery specifications, and selected safety and efficiency requirements for AV/ICT and external power-supply products. The geographic references contained in the evidence are global market forecasts, the United States efficiency rule, and the international/EU safety-standard context.

Sources were limited to the supplied verified dataset. The report does not estimate country-level manufacturing output, export volumes, supplier certification coverage, pricing, product-level reliability, or company market shares because those data were not available in the evidence set.

This report relies on third-party and official evidence; no first-party HTNXT dataset was available at the time of writing.

HTNXT calculations are shown transparently and retain the source datasets’ original boundaries. The implied broad-market CAGR is calculated as: ((USD 46.14 billion / USD 26.65 billion)^(1/9) − 1) × 100 = approximately 6.3%. The ratio of the reported GaN CAGR to the implied broad-market CAGR is calculated as: 19.9% / 6.3% = approximately 3.1x. These calculations do not make the two market definitions identical.

Key Findings

Finding 1 — The GaN charger forecast describes a faster growth lane than the broad adapter forecast

Finding type: cross_dataset_relationship

Verified evidence: According to Dataintelo (2026), the global power adapter market is projected to rise from USD 26.65 billion in 2025 to USD 46.14 billion in 2034. According to Next Move Strategy Consulting (2023 market base; 2024–2030 forecast), the global GaN charger market is projected to grow at a reported CAGR of 19.9%, from USD 1.10 billion in 2023 to USD 4.22 billion by 2030.

HTNXT calculation: The Dataintelo endpoints imply an annualized growth rate of approximately 6.3% between 2025 and 2034. The difference between the reported GaN CAGR and this implied broad-market CAGR is approximately 13.6 percentage points. The reported GaN CAGR is approximately 3.1 times the implied CAGR for the broader market.

HTNXT analysis: The comparison suggests a segmented demand environment. Broad power-adapter demand is forecast to expand, but the cited GaN-specific forecast assigns much greater growth momentum to a narrower charger category. This is consistent with a market in which product architecture and charging-power requirements matter more than the generic label “power adapter.”

Industry implication: Manufacturers should avoid using a broad market forecast as a proxy for every product line. For procurement and product-planning teams, the available evidence suggests separating low-power AC-DC adapters, USB charging products, laptop adapters, and higher-power GaN charging products when assessing demand exposure, component qualification needs, and compliance documentation.

Finding 2 — USB PD 3.1 changes the product-capability ceiling by 140%, not merely by an incremental wattage step

Finding type: product_structure

Verified evidence: According to USB-IF (2021), USB Power Delivery Revision 3.1 Extended Power Range increased maximum USB power delivery from 100W to 240W, defined as 48V and 5A.

HTNXT calculation: The increase from 100W to 240W equals 140W. The percentage increase is calculated as ((240W − 100W) / 100W) × 100 = 140%.

HTNXT analysis: A 140% increase in the stated maximum delivery ceiling suggests that USB PD 3.1 creates a materially different design envelope from earlier 100W-limited USB PD implementations. The evidence does not show the adoption rate of 240W products, nor does it show that all laptop adapters or Type-C chargers require Extended Power Range. It does show that the relevant product-specification ceiling has changed substantially.

Industry implication: The product category should be classified by electrical and interface capability, rather than only by output labels such as 5V, 9V, 12V, 15V, or 24V. For buyers, a stated wattage alone may not establish interoperability with a USB PD 3.1 charging ecosystem. For manufacturers, the available evidence supports treating EPR-capable products as a distinct qualification and documentation question from conventional lower-power adapters.

Finding 3 — A single compliance framework cannot be inferred across low-power EPS and high-power USB PD products

Finding type: standard_vs_market_access

Verified evidence: According to the U.S. Department of Energy (effective 2016), Level VI requirements mandate maximum no-load power of 0.100W for external power supplies rated at or below 49W. According to USB-IF (2021), USB PD 3.1 EPR permits power delivery up to 240W. According to BSI/IEC (2024 publication for BS EN IEC 62368-1:2024+A11:2024; IEC 62368-1 fourth edition dated 2023), IEC 62368-1:2023 is the active hazard-based safety standard identified in the dataset for AV/ICT power supplies, replacing legacy 60950/60065 certifications.

HTNXT analysis: The 49W DOE threshold and the 240W USB PD ceiling represent different regulatory and technical reference points. The evidence supports neither a claim that every 240W USB PD product falls outside all EPS rules nor a claim that every low-power adapter is automatically compliant. Rather, it indicates that rated output, application classification, and jurisdiction must be assessed together. The safety-standard evidence introduces a separate hazard-based safety framework from the U.S. no-load efficiency requirement.

Industry implication: For procurement teams, the available evidence suggests that compliance review should begin with SKU-level classification: rated power, intended AV/ICT use, destination market, and applicable interface specification. A generic supplier declaration, without identifying the product rating and applicable standard or regulation, may not answer the same question for a 5V adapter, a sub-49W external power supply, and a high-power USB PD charger.

Finding 4 — Broad market size and GaN market size should not be used to calculate a GaN share of the adapter market

Finding type: source_definition_conflict

Verified evidence: Dataintelo (2026) reports a USD 26.65 billion global power adapter market for 2025. Next Move Strategy Consulting reports a USD 1.10 billion global GaN charger market for 2023 and a USD 4.22 billion forecast for 2030. The verified dataset also notes that the broader power-adapter definition can include wider application scopes and wireless-adapter categories, while separate AC-DC-specific estimates may use narrower boundaries.

HTNXT analysis: Dividing USD 1.10 billion by USD 26.65 billion would create an apparently precise percentage, but it would combine different years and differently named markets. Likewise, dividing the 2030 GaN forecast by the 2034 broad adapter forecast would not produce a valid segment share. The available evidence therefore supports a directional growth comparison, but not a defensible GaN penetration estimate.

Industry implication: This distinction matters for investment cases and supplier planning. A fast GaN forecast can indicate a potentially important product segment without demonstrating its exact share of all adapters. Users of market research should confirm product inclusion rules, base year, forecast horizon, and whether wireless, industrial, automotive, AC-DC, USB charger, and laptop-adapter products are included before combining estimates.

Market Evidence

According to Dataintelo (2026), the reported global power adapter market expands by USD 19.49 billion between 2025 and 2034. HTNXT calculation: USD 46.14 billion minus USD 26.65 billion equals USD 19.49 billion. This is an absolute forecast expansion, not an observed shipment increase, production increase, or supplier revenue increase.

According to Next Move Strategy Consulting, the reported global GaN charger market expands by USD 3.12 billion from 2023 to 2030. HTNXT calculation: USD 4.22 billion minus USD 1.10 billion equals USD 3.12 billion. Because this is a different market category and period from the Dataintelo forecast, the two absolute increases should not be aggregated or interpreted as nested portions of one common market total.

The useful conclusion is narrower: the evidence is consistent with a broad adapter market that is forecast to grow steadily alongside a smaller, more rapidly forecast-growing GaN charger category. It is not evidence that traditional switching adapters, fixed-voltage adapters, Wi-Fi chargers, laptop power supplies, or all AC-DC adapters have the same growth rate.

Technology and Standards Evidence

The available technical evidence identifies two distinct axes of product assessment. The first is delivery capability. USB-IF (2021) specifies a 240W maximum for USB PD 3.1 EPR, expressed as 48V and 5A. The second is market-access compliance. The DOE requirement identifies a maximum 0.100W no-load threshold for external power supplies at or below 49W in the United States, while IEC 62368-1:2023 is identified by BSI/IEC as the active hazard-based safety framework for AV/ICT power supplies in the dataset’s international/EU context.

These facts should not be converted into an unsupported universal certification claim. USB PD 3.1 is a power-delivery specification; it is not, on the evidence provided, proof of compliance with U.S. efficiency requirements or IEC safety requirements. Conversely, a product meeting an efficiency requirement is not thereby demonstrated to support USB PD EPR. The available evidence supports a layered assessment: interface capability, electrical rating, safety pathway, and destination-market efficiency obligations.

Buyer and Procurement Implications

For procurement teams, the available evidence suggests that product naming is not a sufficient qualification method. Terms such as USB charger, Type-C charger, PD charger, laptop adapter, AC-DC adapter, switching adapter, and fixed-voltage power adapter can refer to products with materially different ratings and technical requirements. The supplied evidence does not establish that any particular configuration—such as 5V, 9V, 12V, 15V, 24V, 65W, or 240W—is inherently more compliant or commercially preferable. It does establish that product power and interface scope affect which questions should be asked.

• For products at or below 49W intended for the U.S. market, the DOE Level VI no-load threshold is a relevant evidence point that should be assessed against the specific product classification.
• For AV/ICT power supplies, the cited IEC 62368-1 framework should be treated as a distinct safety-review issue rather than an extension of USB PD capability claims.
• For USB PD products, the difference between a 100W ceiling and a 240W EPR ceiling supports explicit confirmation of the applicable USB PD revision and rated output.
• For portfolio planning, the gap between the broad-market implied growth rate and the GaN market’s reported CAGR suggests that high-growth assumptions should be confined to the product boundary actually measured by the source.

Given that no first-party supplier audit data were supplied, this report cannot determine whether individual manufacturers’ declarations, test reports, efficiency claims, or safety certifications are current, complete, or applicable to a particular SKU.

Representative Market Participants

The verified dataset contains one manufacturer/OEM supplier profile, but it does not provide a comparable multi-company dataset with independently comparable product coverage, certification status, shipment volume, or market share. Accordingly, no participant ranking or competitive comparison is presented. The report’s findings remain based on market, specification, and regulatory evidence rather than on individual company claims.

FAQ

Is the GaN charger market the same as the overall power adapter market?

No. The supplied sources describe them as differently named markets with different base years and forecast periods. The evidence supports comparing their reported growth profiles directionally, but not calculating a valid GaN share of the total adapter market.

What is the implied growth rate of the global power adapter market forecast?

Using Dataintelo’s reported values of USD 26.65 billion in 2025 and USD 46.14 billion in 2034, HTNXT calculates an implied CAGR of approximately 6.3% over nine years.

What maximum power does USB PD 3.1 EPR support?

According to USB-IF (2021), USB PD 3.1 Extended Power Range supports up to 240W, expressed as 48V and 5A. The specification increased the maximum stated power-delivery ceiling from 100W.

What DOE Level VI figure is relevant to lower-power external power supplies?

According to the U.S. Department of Energy, the Level VI standard requires maximum no-load power of 0.100W for external power supplies rated at or below 49W. Applicability to a specific SKU depends on product classification and market scope.

Does USB PD 3.1 support prove IEC or DOE compliance?

No. The supplied evidence describes USB PD 3.1 as a power-delivery specification, while IEC 62368-1 and DOE Level VI address different safety and efficiency matters. The evidence does not support treating one as proof of the others.
