LED Display USB Cable

This Hetai Tech cable integrates a real-time LED screen that shows charging voltage and current while powering Micro USB devices. It supports QC3.0, QC2.0, AFC, FCP and MTK PE2.0 fast-charging protocols to reduce charge time. The 100 cm length suits desk or bedside use, and the TPE jacket with metal plug shells is built for durability. It targets users who want visible feedback on charger performance and cable health.

Capacity and Headroom

The cable delivers fast charging up to the limits of the connected charger and device, with the LED readout confirming actual voltage and current in real time. It handles data sync alongside power delivery for everyday file transfers. Headroom ends at the maximum current allowed by the phone or charger, so it cannot overcome a weak power source or a device with a low charging ceiling. The 3.28 ft length keeps voltage drop minimal for standard USB-A ports.

Upgrade Path

This replaces a basic charge-only cable that offers no visibility into power flow, letting you verify that a charger meets its rated output. The jump is worth it when you troubleshoot slow charging, test new power adapters, or simply want confirmation that fast-charge negotiation is active. It is not for users who need a USB-C to USB-C connection, a longer run beyond 100 cm, or a cable without the display module.

Questions about this item

Will the LED display on this 100cm cable show voltage and current when I plug it into my older USB 2.0 laptop port?

The LED screen reports real-time voltage and current regardless of the host port generation; it draws its read-out from the charger and device handshake, not from the USB 2.0 data link.

How do I know the LED read-out is accurate after I connect the cable?

Compare the on-screen amperage with the charger's rated output — a 5 V 2 A brick should read near 2.0 A when the phone battery is low, dropping as it fills.

Does the package include a charger or only the 100cm LED display cable?

The box contains one LED display cable; the EU charger and any Micro USB adapter are sold as separate add-ons.
