Technological breakthroughs, market expansion, and policy upgrades jointly build a new industrial ecosystem

1、 Technological innovation: Gallium nitride efficiency revolution, fast charging power repeatedly breaking records Gallium Nitride Technology Breaks Efficiency Ceiling Global power semiconductor company Transphorm and Weiquan Electronics jointly launch 100W USB-C PD power adapter, using innovative SuperGaN ® SiP technology achieves a peak efficiency of 92.7% (under 264VAC full load conditions) in a quasi resonant flyback topology, improving energy efficiency by more than 15% compared to traditional solutions. This technology simplifies circuits through integrated design without the need for additional protective components, reducing the cost of 100W adapters by 30% and providing a cost-effective solution for consumer electronics and AI data centers. Fast charging technology reaches new heights In the field of consumer electronics, the USB-C PD 3.1 standard now supports 240W power output, compressing the charging time of smartphones and ultrabooks to within 15 minutes. Advanced gaming equipment: By 2025, the power of gaming laptop adapters may exceed 400W to meet the power demand of high-performance GPUs.

Poor quality power adapters cause fires, experts call for vigilance in electrical safety

In 2025, a residential building in a certain city suffered a fire due to an overheated power adapter, resulting in direct economic losses exceeding 200000 yuan. This accident once again sounded the alarm for the safety of electronic device charging. Event Review: "Invisible Bombs Charging" According to the fire department, at around 23:00 on July 15th, residents of Building 3 in a certain community were using a non original mobile phone charger in their bedroom when the adapter suddenly exploded and ignited the bed sheets. Although the residents fled in time, the entire bedroom has been burned down. The adapter found on site did not have any safety certification marks and used inferior capacitors and insulation materials internally, "said the firefighter Industry chaos: rampant counterfeit adapters The reporter's investigation found that: 1. There are many hidden dangers on e-commerce platforms: a "fast charging adapter" priced at 9.9 yuan on a certain e-commerce platform has been disassembled and shown to omit key circuits such as overvoltage protection and temperature control 2. Counterfeit certification is common: Multiple market regulatory inspections have found that 38% of "counterfeit adapters" have forged security certifications such as CE and UL 3. Misuse of recycled materials: Some workshops use electronic waste to dismantle materials, and the insulation performance is less than 30% of the standard value This type of product is like a time bomb. "During a demonstration by an engineer from a quality inspection agency, the inferior adapter experienced shell melting at 65 ℃ (normal operating temperature range). Authoritative data: Over 2000 related fires occur annually According to statistics from the National Fire and Rescue Bureau in 2023: -Electrical fires accounted for 33.2%, with power adapter accidents increasing by 17% year-on-year -The accident rate in summer (June August) accounts for 43% of the whole year, with high temperature and air conditioning load being the main causes Expert tip: Four step identification of dangerous adapters 1. Check the label: Identify mandatory certifications such as CCC (China), UL (USA), CE (EU), etc 2. Weight test: Regular products usually weigh over 100g due to the use of copper coils and heat sinks 3. Touch temperature: If the surface temperature exceeds 50 ℃ after charging for 30 minutes, there is a risk 4. Check the interface: Loose plugs and contact sparks are both danger signals Industry in Action -State Administration for Market Regulation: Starting from July, a special rectification campaign to safeguard electricity safety has been launched, and 120000 illegal products have been taken down Top companies: Huawei, OPPO and other brands launch "trade in" campaign, with original adapters starting at 39 yuan New technology solution: The "fused fireproof shell" developed by a certain technology company has passed testing and can self seal at the moment of fire **Special Reminder** The fire department suggests: ✅ Avoid overnight charging ✅ Stay away from flammable materials such as beds and sofas ✅ Stop using the adapter immediately if it is found to be expanding or making abnormal noises ❌ Do not purchase products with prices significantly lower than the market
