LUOM BK376 48W QC3.0 Wall Charger

This LUOM BK376 wall charger delivers 48 W total output through four USB ports, making it suitable for users who need to charge a phone, tablet and smaller accessories from one outlet. The compact black unit accepts AC 100-240 V input, so it works in home, office or travel settings without a separate converter. Built-in safeguards protect connected devices during every charging session.

Single Quick Charge 3.0 Port Decides Compatibility

Only one of the four ports supports Quick Charge 3.0 at 5 V/3 A maximum, while the remaining three ports share a 5 V/2.4 A maximum each. If your device requires Quick Charge 3.0 for its fastest charging speed, you must use that specific port; other devices will fall back to standard 5 V charging on any port. Check your device’s supported protocol before relying on the faster rate.

Steady Output Under Continuous Multi-Device Load

When all four ports are used simultaneously the charger manages total output up to 48 W, distributing current according to each device’s negotiated requirement. The intelligent chip adjusts per-port delivery so that sustained charging remains stable without tripping the protection circuits. Thermal limits are handled internally, so the unit maintains its rated performance during extended multi-device sessions.

Questions about this item

What does the 48 W total output mean when four devices are plugged in?

The charger can deliver up to 48 W combined across all four ports, so the power is shared among connected devices rather than giving each port the full amount.

How does Quick Charge 3.0 on one port affect the other three ports?

One port supports Quick Charge 3.0 while the remaining three standard USB ports each provide up to 5 V at 3.1 A or 2.4 A maximum, all operating simultaneously.

Will the US plug fit a standard North American wall outlet without an adapter?

Yes, the unit comes with a US plug designed for 100–240 V AC sockets, so it connects directly to standard North American outlets.
