USB-C to HDMI Adapter Hub for Phones, Laptops & TVs

Phone or laptop to the big screen, plus two USB ports.

Modern phones and thin laptops give you one USB-C port and not much else. The TV in the donga, the caravan telly, the projector in the meeting room — they all take HDMI, and you are standing there with no way to plug in.

This 4-in-1 hub is the way in. The built-in USB-C lead plugs into your phone, tablet or laptop and sends the picture out through HDMI — the supplier rates it at up to 4K at 30 Hz. Beside the HDMI you get two USB-A ports for a keyboard, mouse or flash drive, and a USB-C socket the supplier's own photos show feeding pass-through charge while the screen runs.

One thing to check before you buy: your device's USB-C port has to support video output, called DisplayPort Alt Mode. Plenty of phones and some budget laptops do not have it, and on those the HDMI side of this hub will never light up. Full detail under Limits.

What It Does

• Big-screen mirroring: puts a phone, tablet or laptop display onto any HDMI TV, monitor or projector.
• Desktop from a phone: the supplier's photos show it running Samsung DeX with a monitor, keyboard and mouse off one phone.
• Two USB-A ports: one marked USB 3.0 and one marked USB 2.0, for keyboards, mice and flash drives.
• Charge while it works: the USB-C socket takes your existing charger so the phone is not going flat while it drives the screen.
• One captive lead: the host cable is built in, so there is no separate cable to lose out of the bag.

Key Features

• Four ports in one: HDMI out, a USB-A port marked USB 3.0, a USB-A port marked USB 2.0, and a USB-C charging socket.
• HDMI output: rated by the supplier at up to 4K at 30 Hz.
• Pass-through charging: supplier images show a wall charger feeding the USB-C socket while the display runs; wattage not stated.
• Pocket sized: supplier states 100 mm long and 80 g — it lives in the laptop sleeve, not on the desk.
• Metal shell: grey metal housing with a blue indicator LED beside the USB-C socket.
• No external power: the hub itself runs off the host device — nothing extra to plug in for the USB ports.
• No software listed: the supplier lists no apps or accounts — it is a plug-in lead, not a smart gadget.

Limits

Straight up, because this is the stuff that gets adapters sent back:

• No DisplayPort Alt Mode, no picture: the HDMI output depends entirely on your device pushing video out of its USB-C port. If your phone, tablet or laptop does not support DisplayPort Alt Mode (or Samsung DeX on Samsung phones), the screen stays black — the USB ports will still work, but HDMI never will. Search your exact model plus "DisplayPort Alt Mode" before ordering. This is the single most common reason adapters like this get returned.
• Assume 30 Hz at 4K: the supplier's figure is 4K at 30 Hz. That is fine for movies, browsing and spreadsheets; it is not what you want for fast-moving games on a 4K screen.
• A marking is not a speed: one port is marked USB 3.0, but the supplier publishes no measured transfer rate. Fine for keyboards, mice and everyday flash drives; do not buy it around a transfer number nobody has stated.
• Charging wattage unstated: the USB-C socket is only ever shown as a charger input, and the supplier does not state its pass-through wattage. A phone should be happy; a hungry laptop may charge slowly or not at all.
• HDMI and USB only: no card reader, no Ethernet, no headphone jack, and one screen only — there is a single HDMI output.

Q & A

Will it work with my phone or laptop?

If your device's USB-C port supports DisplayPort Alt Mode, yes. The supplier's photos show it running Samsung DeX. If you are not sure, search your exact model plus "DisplayPort Alt Mode" or "video output over USB-C" — if your device lacks it, the HDMI side of this hub will never work, no matter the cable or the TV.

Is the picture 4K at 60 Hz?

Assume not. The supplier states up to 4K at 30 Hz and publishes no 60 Hz figure. At 30 Hz, movies and desktop work look fine; fast gaming does not.

Does it charge my phone while it is driving the TV?

The supplier's photos show exactly that — a wall charger plugged into the hub's USB-C socket while the phone runs a desktop on the monitor. The pass-through wattage is not stated, so use the charger that came with your device.

Are the HDMI lead and USB cables in the photos included?

The supplier does not state the package contents, and the cables in the photos are examples of what plugs in. Plan on receiving the hub only, and count it a bonus if anything else turns up in the box.

Can I plug a flash drive or SSD into the USB-C socket?

Do not count on it. The supplier only ever shows that socket used for charging and does not state it carries data. Use the two USB-A ports for storage and accessories.
