FIXED Data Blocker 2in1 – Compact USB Data Blocker for Safer Charging from Public USB Ports

FIXED Data Blocker 2in1 is a compact security accessory that allows you to charge a smartphone, tablet, laptop, or another compatible USB-C device from a public or unfamiliar USB port without enabling data communication. The adapter is designed to physically block the USB data lines while keeping only the electrical connection required for charging active. This helps reduce the risk of unwanted data communication between your device and an unknown public charging point.

The set includes two adapters: one with a USB-C to USB-C connection and another with a USB-A to USB-C connection. Both adapters provide a USB-C interface for connecting your device or charging cable, allowing the same set to be used with both modern USB-C charging points and traditional USB-A ports. The USB-C version supports up to 240W USB Power Delivery charging, making the Data Blocker suitable not only for smartphones but also for higher-power tablets and compatible laptops.

Physically Blocked Data Connection

The most important feature of the FIXED Data Blocker 2in1 is its physically disconnected data path. A standard USB cable can carry both electrical power and data at the same time. When such a cable is connected to an unfamiliar USB port, a data communication channel may be established in addition to the charging connection.

The Data Blocker is positioned between the charging port and the user’s USB-C cable. Inside the adapter, the contacts required for data transmission are blocked while the contacts necessary for charging remain active. As a result, the connection can still be used for power delivery, but standard USB data transfer is prevented.

This type of solution is particularly useful when the technical design or trustworthiness of the charging source is unknown.

Safer Charging from Public USB Ports

Built-in USB charging ports are commonly found in airports, hotels, cafés, libraries, conference centres, and other public locations. They are convenient, but users cannot always verify exactly what is connected behind the charging port.

FIXED Data Blocker 2in1 is designed specifically for these situations. It allows a third-party USB port to be used solely as a power source while preventing a conventional data connection from being established through it.

In practical terms, this means you do not always have to avoid a conveniently available USB charging point while travelling simply because its origin or technical setup is unknown.

Two Adapters in One Set

The name FIXED Data Blocker 2in1 refers to the fact that the package contains two adapters with different connector types. For USB-C charging points, the set includes a USB-C to USB-C adapter, while for older but still widely used USB-A ports, it includes a USB-A to USB-C adapter. In both cases, the user’s USB-C charging cable is connected to the charging source through the Data Blocker.

This combination makes the set much more versatile while travelling. One airport may provide USB-A charging ports, while a newer hotel room may offer USB-C sockets. With both adapter types included, there is no need to know in advance which type of charging connection will be available.

USB-C Version Supports up to 240W Power Delivery

Blocking data communication does not have to mean slow charging. According to the manufacturer, the USB-C to USB-C adapter in the FIXED Data Blocker 2in1 supports up to 240W Power Delivery charging, with a maximum electrical specification of 48 V / 5 A.

This is an important advantage over simpler data blockers that may significantly limit charging performance. Support for up to 240W means the adapter can also be used in high-power USB-C charging setups, provided that the charger, cable, and connected device all support the required USB Power Delivery level.

As a result, the adapter can be used not only for charging smartphones or wireless headphones but also with compatible tablets and USB-C laptops.

USB-A Adapter for Traditional Charging Points

Traditional USB-A charging ports remain common in public spaces. For these, the FIXED Data Blocker 2in1 includes a separate USB-A to USB-C adapter.

According to the manufacturer’s technical specifications, the USB-A version supports charging at up to 5 V / 3 A. This makes it suitable for use with standard USB-A charging points and devices such as smartphones and smaller mobile accessories.

Naturally, a USB-A connection cannot provide the same 240W Power Delivery capability as the USB-C version, but the main function remains the same: electrical power is allowed through while data communication is blocked.

Suitable for Smartphones, Tablets, and Laptops

FIXED has designed the Data Blocker for use with a wide range of mobile devices. When paired with a USB-C charging cable, the adapter can be used not only with smartphones and tablets but also with compatible laptops.

The USB-C adapter’s support for up to 240W Power Delivery provides particularly broad flexibility. A smartphone with low power requirements will draw only the charging power it supports, while a higher-powered compatible laptop may use a much more demanding charging profile.

Actual charging speed always depends on the combined capabilities of the charging source, Data Blocker, cable, and connected device.

Practical for Business Travel

Business travellers often rely on unfamiliar charging points in airports, hotels, conference centres, or temporary offices. At the same time, laptops and smartphones may contain work-related files, user accounts, and other data where unnecessary data connections are best avoided.

FIXED Data Blocker 2in1 effectively turns a public USB port into a charging-only connection. Users can connect their own USB-C cable through the adapter and continue charging without opening a conventional USB data channel.

Its compact size means this additional layer of protection takes up virtually no space in a tech bag.

Durable Aluminium Housing

Both FIXED Data Blocker 2in1 adapters feature a durable aluminium housing. The metal construction gives each small adapter a rigid outer shell, making it well suited for an accessory that may frequently be carried in a pocket, backpack, or cable organiser.

As a travel accessory, the Data Blocker is exposed to repeated connection, removal, and transportation. The aluminium housing helps protect the internal construction from normal everyday wear.

Despite the metal enclosure, the adapters remain extremely lightweight and add virtually no noticeable weight to travel equipment.

Compact Dimensions for Everyday Carry

FIXED Data Blocker 2in1 is designed to be as compact as possible. The USB-C adapter measures approximately 22.7 × 11.2 × 6.2 mm, while the USB-A adapter measures around 21.4 × 15 × 6.6 mm. Each adapter weighs only about 3 grams.

At this size, both adapters can be stored in a cable organiser, a small laptop-bag pocket, or a travel accessory case without requiring meaningful additional space.

This small form factor is an important advantage for a security accessory: it is only useful if you actually have it with you when using a public charging point.

Useful for Professional Photo, Video, and Drone Equipment

A professional equipment kit may include several USB-C rechargeable devices such as remote controllers, monitors, smartphones, tablets, laptops, and power banks. During production days, these devices often need to be charged wherever a free power source is available.

FIXED Data Blocker 2in1 allows an unfamiliar USB port to be used for charging without enabling normal USB data communication. The USB-C adapter’s support for up to 240W Power Delivery is particularly useful in professional environments because it is not limited to low-power smartphone charging.

This makes the Data Blocker a practical addition to the equipment bag of photographers, videographers, drone operators, and other mobile professionals.

A Data Blocker Is Not the Same as a Standard USB Adapter

From the outside, FIXED Data Blocker 2in1 may resemble a simple USB adapter, but its purpose is fundamentally different. A conventional adapter usually preserves both the power and data connections and simply changes the connector type.

With a Data Blocker, the data contacts are intentionally disabled. This means the adapter is specifically intended for situations where charging is required but data communication is not.

For this reason, the Data Blocker is not suitable for tasks such as transferring files, synchronising a smartphone with a computer, or using other USB data functions. In those situations, the adapter must be removed and a normal direct connection used.

Technical Design

FIXED Data Blocker 2in1 consists of two aluminium-housed USB adapters that allow the electrical connection required for charging to pass through while physically blocking the USB data lines. One adapter uses a USB-C connection and the other USB-A, while both are designed for use with a USB-C charging cable.

The USB-C to USB-C adapter supports USB Power Delivery charging up to 240W, or up to 48 V / 5 A. The USB-A to USB-C adapter supports charging at up to 5 V / 3 A. The USB-C adapter measures approximately 22.7 × 11.2 × 6.2 mm, while the USB-A version measures around 21.4 × 15 × 6.6 mm. Each adapter weighs approximately 3 grams, and both feature an aluminium housing.

A Simple Extra Layer of Everyday Digital Security

Digital security is not limited to passwords, software updates, and authentication. Physical connections also determine which communication channels a device can establish with the outside world.

FIXED Data Blocker 2in1 provides a simple way to physically disable USB data communication in situations where only charging is required.

The adapter does not replace the device’s built-in security features or standard cybersecurity practices, but it adds a clear and practical layer of protection when using public USB charging points: the electrical charging connection remains active while the data connection is blocked.
