This USB-A adapter is purpose-built for specialist applications where power transmission is not desired — allowing data transfer while blocking the 5V power line. Ideal for 3D printers, Raspberry Pi projects, and similar electronics setups. ⚙️⚡

🧰 Key Features

✔ D+, D-, and Ground (0V) connected for full data transmission
✔ 5V line disconnected — prevents power from passing through
✔ USB 2.0 data transfer support
✔ Perfect for use with:
• 3D printers 🖨️
• Raspberry Pi boards 🍓
• Debugging and low-level device interfacing
• Preventing power loops or unwanted power input

⚠️ Important Usage Notes

🚫 This is NOT a power blocker for smartphones or tablets
🚫 Will NOT support data transfer for devices that rely on USB power
🚫 NOT suitable for charging or syncing mobile devices

• Isolate data lines from 5V power in sensitive systems

• Specialized hardware interfacing or testing scenarios

❓ Frequently Asked Questions (FAQs)

🔌 Can I use this with a phone or tablet?
No — many phones and tablets require power to enable data transfer. This adapter disables the 5V line, so it won’t work with them.

🧪 What is this used for?
Primarily for 3D printers, Raspberry Pi, and specialty electronics where data is needed but power input must be blocked.

💡 Is this a data blocker?
No — this adapter allows data, but blocks power. Data blockers disable data and allow power — this is the opposite.

🇬🇧 Who makes this?
PortaPow, a UK-based company known for smart USB connectivity tools.
