What Makes Legacy Devices Still Demand USB-A Ports in Travel Chargers?
Legacy devices like pre-2018 Android phones, earbuds, and accessories rely on USB-A ports, with 40–50% of global fleets still USB-A dependent.

Hybrid 1A1C or 2A2C configs future-proof travel chargers for mixed scenarios like business trips or gifting, ensuring broad compatibility without inventory splits.

1A1C setups provide one USB-A port for legacy devices plus USB-C with PD/QC for modern fast charging, perfect for 20W–30W GaN travel adapters under 100g. Wecent’s foldable plug models deliver 96% GaN efficiency, low heat for air travel, and support low MOQ of 200 pcs with logo and packaging customization. Unlike USB-C-only, hybrids broaden sales for wholesalers without separate stock.
