Portable 48W 4-port USB charger

This 48W wall charger delivers Quick Charge 3.0 from one port and up to 5V 3.1A from the other three, letting you charge four devices at once. The foldable plug and compact black body suit home, office or travel use. A built-in intelligent chip matches the current each device needs, supporting fast charging without stressing the battery.

Practical limits of QC 3.0 and shared output

Quick Charge 3.0 operates only on a single port; the remaining ports share a combined 5V 3.1A maximum. Total output is capped at 48W, so connecting four power-hungry tablets will throttle each port. Input accepts AC 100-240V at 50-60Hz, making it usable worldwide with a simple plug adapter, but it cannot supply higher-voltage profiles such as USB Power Delivery.

Installation and common issues

Plug the unit into any standard wall socket and connect your cables; no drivers or configuration are required. The most frequent problem is expecting all four ports to fast-charge simultaneously — only the QC 3.0 port negotiates elevated voltage. Using low-quality or overly long cables can also reduce delivered current, so keep cables short and certified for the device’s rated amperage.

Questions about this item

How do the four ports share the 48 W total when I plug in multiple devices?

One port delivers Quick Charge 3.0 while the other three share a 5 V / 3.1 A maximum; the charger intelligently distributes current up to the 48 W limit across all connected devices.

Will the Quick Charge 3.0 port actually fast-charge my phone, or does it fall back to standard speeds?

The QC 3.0 port negotiates higher voltages with compatible phones so they charge at their maximum supported rate; non-QC devices simply receive 5 V up to 3.1 A from any port.

Can I use this charger abroad without a voltage converter?

Yes, the input accepts AC 100–240 V at 50–60 Hz, so it works worldwide with only a plug adapter for the local socket.
