ESTONE 48W 4-USB QC3.0 Portable Travel Plug Black for iPhone Xs XS Max XR X 8 7 6 Plus iPad Pro Air

48 W four-port USB charger

This 48 W wall charger delivers power through four USB ports, one supporting Quick Charge 3.0 and three providing up to 5 V / 3.1 A each. It accepts AC input from 100 V to 240 V at 50 Hz to 60 Hz, making it suitable for worldwide travel. The compact black housing is designed for home, office or indoor use. Built-in protections and an intelligent chip match current to each connected device.

Quick Charge 3.0 single-port limit

Only one port operates at the Quick Charge 3.0 profile; the remaining three ports share a 5 V / 2.4 A maximum per port. Total combined output is capped at 48 W, so charging four power-hungry devices simultaneously will reduce per-port current. The charger does not support higher-voltage USB Power Delivery standards or programmable power supply modes. Buyers needing multiple high-voltage fast-charge ports should look elsewhere.

48 W total power budget

The 48 W ceiling is the single figure that determines whether this charger can handle your device mix. If the combined draw of your phone, tablet and accessories stays below that limit, all four ports will maintain their rated output. Exceeding it triggers protection circuits that lower current across the ports. Check each device's rated input power before relying on simultaneous charging.
