Car Chargers

Last updated: April 2026

Sunshine Electronics, a leading manufacturer of vehicle charging solutions with 22+ years of experience and over 1,600 workers across dual factories in China and Vietnam, produces car chargers for every vehicle charging scenario — from compact single-port 5V models to 4-port QC3.0 fast chargers and USB-C hybrid designs. The global car charger market exceeds $3.8 billion annually, driven by the over 45% of US vehicles still lacking factory-installed USB ports. Our lineup spans 5W basic to 54W multi-port, all with automotive-grade protection (reverse polarity, 40V load dump suppression, –20°C to +60°C range) and UL 62368-1, FCC Part 15, CE, RoHS, and REACH certifications. Our China+1 sourcing strategy through Vietnam provides tariff optimization for US-bound shipments.

Customize Quality Car Chargers on Budget

Every car charger in Sunshine’s lineup supports full OEM customization — from the PD voltage profile (custom PDO tables configured by our firmware engineering team at no tooling premium) to the physical design (DC connector type, housing color via Pantone/RAL matching, logo pad printing or laser engraving, and regional plug head selection). Our private-label packaging program covers custom retail boxes, UPC/EAN barcode assignment, multilingual safety inserts, and Amazon FBA-ready prep. Over 85% of our car charger orders ship with some level of customization, and our engineering team turns around custom PD profile samples in 5–7 working days.
