Real-time charging monitor

The DELL TUA04 adapter integrates an LED display that shows power, current and voltage while charging. It supports USB4 connectivity for Thunderbolt 4 and 3 devices. Compatible with MacBook Pro, MacBook Air, iPad Pro, iPhone 15 and 16 series plus other USB-C equipment. The unit weighs 0.02 kilograms and measures 14.33in wide by 12.83in high by 9.06in deep.

Build integration and freedoms

The adapter delivers up to 240W through its built-in E-marker chip using PD 3.1, while remaining backward compatible with PD 3.0 and 2.0. It handles 48V at 5A and works with 140W, 100W and 60W power sources. Data moves at 40Gbps over the USB4 link. Video output reaches 8K at 60Hz or dual 4K at 60Hz when the host port supports DP Alt Mode.

Sustained-load behaviour

Under continuous use the adapter maintains the full 240W rating without throttling. The LED readout lets you verify that voltage and current remain stable during long charging or data sessions. Backward compatibility with USB 3.2, 3.1 and 2.0 ensures older peripherals stay functional. The 20V, 11.8A AC input and 96W battery spec support consistent delivery across extended workloads.

Questions about this item

Does the 240 W power delivery sustain full output without thermal throttling?

The adapter is rated for 240 W via PD 3.1 at up to 48 V and 5 A, with an E-marker chip that maintains the negotiated power profile during sustained use.

How hot or noisy does the TUA04 get when running at high load all day?

The unit has no fan and no moving parts; heat is dissipated through its compact aluminium shell, so it runs silently and stays warm but not hot under continuous 240 W loads.

What host port must my laptop already have to use the 8K@60 Hz video output?

Your laptop needs a USB-C port that supports DisplayPort Alt Mode; without DP Alt Mode the video function will not activate even though the adapter carries the 40 Gbps USB4 link.
