What is the SD card read speed on the PF433A?

The SD 3.0 UHS-I module delivers up to 104MB/s sustained read speed, the full rated bus capacity. This is a genuine high-speed interface, not a limited slot, designed for fast media offloading.

Can I charge my laptop while using HDMI and USB devices simultaneously?

Yes. The dedicated 60W USB-C PD port supplies power independently while the other ports (HDMI, USB-A, SD reader, USB-C data) remain fully operational.

What does 'modular' mean for the PF433A?

The functional modules—SD reader, HDMI, USB ports—are integrated as replaceable system components rather than fixed moulding. The PF434A 7-in-1 variant adds a Gigabit Ethernet module using the same modular platform.

Is the PF433A available for OEM/ODM customization?

Yes. Branding and packaging are customizable for OEM/ODM orders through Tonetron (ISO 9001 certified, exporting to 40+ countries since 1984).

Why aluminium shell instead of plastic?

Aluminium provides superior heat dissipation, which is critical when the adapter runs simultaneous outputs—4K display, two USB devices, and SD card reader—under sustained load.

Overview

The PF433A is built around an SD card module. It provides HDMI at 4K@30Hz, two USB 3.0 Type-A ports at 5Gbps, a USB-C data port, a 60W USB-C PD port, and an SD 3.0 UHS-I reader rated at up to 104MB/s.

The card reader specification is the part worth reading closely. SD 3.0 UHS-I at up to 104MB/s is the full rated speed of the bus, not a token slot — the difference between offloading a shoot in minutes and waiting through it. For photographers, videographers and drone operators working on USB-C laptops with no built-in card slot, that is the daily bottleneck this removes.

"Modular" describes the construction: the function modules are part of a system rather than a fixed moulding. The PF434A in the same range is the 7-in-1, which adds a Gigabit Ethernet module with a folding plug on top of everything this model carries — the option to take if wired networking is also needed.

HDMI at 4K@30Hz drives a 4K display at native resolution; the separate 60W PD port keeps the laptop charging while the rest is in use.

TPE cable with a black aluminium shell, which dissipates heat better than plastic on an adapter running a display output, two USB ports and a card reader together. Branding and packaging are customisable for OEM/ODM orders.
