Indicates whether the product comes with an AC power adapter included in the package. A value of "Yes" means a charger is supplied, while "No" indicates that no charger is provided and the user must obtain one separately.

The frequency of the alternating current supplied to a power supply or charger, expressed in hertz (Hz). It indicates the acceptable operating range for the electrical mains that powers the device, ensuring proper functionality and safety.

The range of alternating current voltage that the product accepts from its power source, expressed in volts (V). It indicates the minimum and maximum supply voltages compatible with the device across different regions.

The total count of antenna units present on a device or system. It indicates how many separate antennas are installed and can help assess potential signal coverage and performance.

A list of web browsers that the product can run or support, typically including major desktop and mobile browsers such as Chrome, Firefox, Safari, Edge, Internet Explorer, Opera, and others. Each value represents a distinct browser name or version range that has been verified to work with the device.

A list of the cable types that are supplied with the product, such as USB, HDMI, VGA, DisplayPort, LAN (RJ‑45), SATA, audio or other relevant connectors.

The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

Indica el tipo o estándar de la conexión Ethernet que posee un producto, como Gigabit Ethernet, 10 GbE, 2.5 GbE, Fast Ethernet, etc. Los valores suelen ser textos descriptivos sin unidades numéricas y pueden incluir varias opciones separadas por comas cuando el dispositivo soporta más de una velocidad.

The Harmonized System (HS) code is a standardized numerical identifier used internationally to classify traded goods. It consists of up to six digits, where each pair of digits represents progressively more specific product categories. The HS code facilitates customs duties, trade statistics, and regulatory compliance by providing a common language for describing products across borders.

The highest theoretical speed at which a device can send or receive data over a wireless network, expressed in megabits per second (Mbps). It represents the peak throughput under optimal conditions and is useful for comparing performance across routers, access points, and other Wi‑Fi equipment.

The modulation technique used by a wireless device or component to encode digital information onto a carrier signal. Common schemes include QAM, OFDM, PSK, FSK and their variants. This attribute helps users understand the signal processing method and compatibility with other equipment.

The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

The electrical current drawn by a device from its power source, expressed in amperes (A). It indicates how much current the product consumes during normal operation and helps determine compatibility with power supplies or USB ports.

The electrical potential difference that a device delivers to its load, expressed in volts (V). It indicates the nominal voltage supplied by the product’s power output and is useful for matching it with compatible accessories or systems.

The main electrical supply that powers the device, such as mains electricity (AC), battery, USB power, PoE, or a combination of these options.

A list of cryptographic and authentication methods that a device can use for secure communication or data protection. Each entry represents a distinct algorithm or protocol, such as encryption ciphers (e.g., AES, WEP), authentication mechanisms (e.g., RADIUS, WPA‑PSK), or network security protocols (e.g., HTTPS, SSL/TLS). The values are typically separated by commas and may include both technical identifiers and consumer‑friendly labels.

The range of relative humidity (expressed as a percentage) within which the storage device is designed to operate reliably. Values are given as a minimum–maximum interval such as "10 - 90 %" and indicate the acceptable environmental moisture level for optimal performance.

A list of environmental, safety or quality certifications that a product has obtained from recognized authorities. Typical entries include RoHS, ENERGY STAR, CE, WEEE, TCO Certified, FCC, and other industry‑specific standards.

A list of the wireless networking protocols and frequency bands that a device can connect to, such as IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, Wi‑Fi 4 (802.11n), Wi‑Fi 5 (802.11ac) or Wi‑Fi 6 (802.11ax). The values are typically separated by commas and may include both the technical name and a consumer‑friendly label.

The radio frequency band(s) that a wireless device supports, expressed as free text such as "Dual-band (2.4 GHz / 5 GHz)", "Single-band (2.4 GHz)", or "Tri‑band (2.4 GHz / 5 GHz / 5 GHz)". It indicates the spectrum(s) on which the device can transmit and receive Wi‑Fi signals.

A list of the wireless networking protocols and frequency bands that a device can connect to, such as 802.11a, 802.11b, 802.11g, Wi‑Fi 4 (802.11n), Wi‑Fi 5 (802.11ac) or Wi‑Fi 6 (802.11ax). The values are typically separated by commas and may include both the technical name and a consumer‑friendly label.

Maximum theoretical speed at which a device can send or receive data over its first Wi‑Fi band, expressed in bits per second (bps) or multiples such as kbps, mbps, gbps. It represents the upper bound of throughput under optimal conditions and allows comparison of wireless performance across devices.
