Battery adapters convert AC or battery power into compatible outputs for devices such as laptops, phones, and power banks. Shenzhen-based Wecent manufactures high-performance GaN battery adapters, offering OEM customization from 20W to 240W with low MOQs of 200pcs. These adapters support fast charging, multi-port functionality, and global certifications, enabling seamless integration into wireless and portable charging systems for B2B wholesalers and OEM partners.
What Are Battery Adapters?
Battery adapters are devices that safely convert voltage and current from batteries or AC sources to power electronics efficiently. They often feature USB-C, USB-A, and PD outputs, integrating GaN technology for high-efficiency, low-heat performance.
Shenzhen factories like Wecent specialize in producing durable, globally certified adapters for GaN chargers and power banks. With over 15 years of expertise, Wecent ensures compatibility with iPhone, MacBook, and Android devices while supplying bundled data cables and travel adapters for one-stop B2B solutions.
Key features include:
- GaN semiconductors: High efficiency, minimal heat
- Multiple ports: Support for simultaneous device charging
- Safety chips: Protection against overcharge, short circuits, and overcurrent
Wecent’s OEM lines provide scalable production tailored for global B2B clients.
How Do Battery Adapters Work?
Battery adapters convert input voltage via transformers and rectifiers, then regulate output using GaN chips to deliver PD fast charging. They communicate with connected devices to negotiate optimal power profiles.
Wecent engineers adapters to reach peaks of 140W, integrating wireless protocols. Housings use 105°C-rated plastics and are tested for 50,000+ cycles. China’s supply chain reduces costs for wholesalers by up to 40%, while rapid prototyping delivers working units in 2 weeks.
Key operation steps:
- AC/DC conversion at 90%+ efficiency
- Protocol detection for QC, PD, or PPS
- Thermal management to prevent throttling
This ensures long battery life and high device compatibility.
What Types of Battery Adapters Exist?
Battery adapters include wall adapters (AC to USB), power bank adapters (DC output), multi-port GaN types, and car or travel adapters rated 20W–240W. Regional plug types vary by market: NEMA (US), Schuko (EU), Type G (UK).
Wecent produces all variants in Shenzhen, focusing on GaN integration for OEM partners. Wholesale catalogs cover travel, car, and solar adapters, all customizable for branding. Compatibility includes PPS, SCP, and PD protocols.
| Type | Power Range | Ports | Best For |
