Industrial-Grade Manufacturing meeting Global Safety Standards (CE, UL, TUV)
Known as "Granny Chargers" (Level 1 or Level 2 portable chargers), these devices are the bedrock of EV adoption. They bridge the gap between fixed public infrastructure and home convenience, allowing users to charge from any standard domestic socket.
Our factory prioritizes Triple-Thermal Protection and RCD leakage protection. Wholesale Granny Chargers must meet IEC 62752 standards to ensure long-term residential safety, preventing overheating during 10+ hour charging cycles.
From Type 2 (Mennekes) for Europe to Type 1 (J1772) for North America, our manufacturing lines produce region-specific plug configurations including UK 3-pin, Schuko, and CEE industrial plugs.
China has established an unparalleled ecosystem for EVSE (Electric Vehicle Supply Equipment). The advantages of partnering with a top-tier China factory like Tongxing New Energy include:
A National High-Tech Enterprise with 23 Years of Energy Sector Mastery

Rooftop solar panels provide real-time power, meeting 30%-50% of charging demand. Supports 120kW-960kW ultra-fast charging to add 200km range in 10 minutes.
Modular energy storage (100kWh-10MWh) enhances peak-valley tariff arbitrage benefits by 30% while serving as 72-hour emergency supply.
Grid-free operation with 72-hour continuous power supply for campsites, mining areas, and rural scenic spots with unstable grids.
As a leading Wholesale EV Charger Factory, we track the shifts in global user intent and technology requirements:
Future Granny Chargers won't just draw power; they will push it back. Vehicle-to-Home (V2H) technology allows EVs to act as mobile batteries, powering homes during peak grid hours or outages.
As charging speeds increase, even in portable units, thermal dissipation becomes critical. Our factory uses military-grade materials to ensure performance in temperatures from -35°C to 75°C.
Modern procurement demands Dynamic Load Balancing (DLB). This ensures that the charger adjusts its draw based on other household appliances, preventing fuse trips and optimizing energy use.
When selecting an EV Granny Charger factory partner, professional buyers must evaluate:
Expert insights into EV charging infrastructure and wholesale procurement
Scaling from Residential AC to Mega-Watt DC Infrastructure
Flexible Power Management for Every Environment
Prioritizes PV/storage power, automatically supplementing with low-cost grid power during off-peak hours to minimize bills.
Leverages 100% renewable energy use, achieving zero carbon emissions for green factory certifications and eco-conscious users.
Automatically switches to backup power during grid outages, ensuring 72-hour supply for essential appliances and lighting.
