Fervit USB-C Male to Female PD Blocker 5.1K Resistor DC5V power adapter

SKU CH-JXHW-2WJ5Q

A USB-C male-to-female adapter that blocks 20V PD power, passes only DC 5V via a 5.1K resistor, supports USB 2.0 data at 480Mbps, and uses a metal casing for durability

  • Blocks 20V PD power to protect 5V devices
  • 1K resistor ensures stable DC 5V charging
  • Integrated detection prevents overcharging and overheating
  • Metal casing resists daily wear and damage
  • USB 2.0 data transfer up to 480Mbps

PD 20V blocker for 5V devices

This Fervit adapter sits between a USB-C power source and a DC 5V device, using a 5.1K resistor to physically block 20V Power Delivery while passing only 5V. It targets users who need to charge shavers, headphones or electric screwdrivers from high-voltage chargers without risking over-voltage damage.

Data limited to USB 2.0 480Mbps

The female port carries USB 2.0 signals at up to 480Mbps, so file transfers work for basic peripherals but saturate quickly with large media. It is not suited for video output, high-speed storage or any workflow that demands USB 3.1 Gen 1 or Gen 2 bandwidth.

Metal shell runs cool and silent

A resilient metal casing dissipates the minimal heat from 5V charging without a fan, keeping operation silent in office or travel use. The reversible USB 3.1 Type-C plug orientation adds convenience, while the blocker function prevents the overheating that can occur when 20V reaches a 5V-only device.

Questions about this item

Will this blocker let my USB 2.0 cable still move data at 480 Mbps while it stops 20 V PD power?

Yes, the adapter supports USB 2.0 data transfer up to 480 Mbps while its 5.1 K resistor blocks 20 V PD and passes only 5 V DC for charging.

How can I confirm the 5.1 K resistor is limiting output to 5 V after I plug it in?

Use a USB-C power meter between the blocker and your device; it should read 5 V DC with no 20 V PD negotiation shown.

Does the pack contain only the five metal-cased Type-C male-to-female adapters, or are cables included?

The lot supplies five PD-blocking adapters with reversible Type-C connectors; no charging or data cables are bundled.
