Five-bay drop-in charger for IR RX20 infrared

The Williams AV CHG 520 is a multi-unit, drop-in charger designed to charge and store up to five Williams AV IR RX20 under-the-chin infrared receivers. Its five-unit capacity, individual red LED charging indicators, and clearly defined footprint make it a focused charging solution for systems that use multiple compatible receivers.

Ideal Use Cases

The CHG 520 is suited to installations that maintain several IR RX20 receivers and need a single location for both charging and storage. Rather than handling each compatible receiver with a separate charger, operators can place as many as five units in the same charger. This format is particularly relevant when multiple IR RX20 receivers must be organized together and prepared for repeated use. Compatibility in the supplied product data is specifically identified for Williams AV IR RX20 under-the-chin style infrared receivers; compatibility with other receiver models is not specified.

Why Choose This Model

The primary advantage of the CHG 520 is its combination of five-bay capacity and drop-in operation. Each compatible receiver can be placed into the charger without distributing the units among separate charging locations. Individual red LED charging indicators provide a visible indicator for each charging position. The charger also serves as a storage point for up to five receivers, helping keep the supported devices together. Its enclosure uses black metal and plastic, while the complete unit weighs 13.6 ounces.

Installation and Integration

The charger measures 12 inches long by 6.25 inches wide by 1.5 inches high, equivalent to 30.48 by 15.875 by 3.81 centimeters. These measurements define the space that should be allocated when integrating the CHG 520 into an existing IR RX20 storage and charging area. The product documentation lists a power-supply input of 120 VAC and separately lists the power supply as 100-240V / 5 VDC. These stated electrical values should be retained when planning the installation. Once connected to the specified power arrangement, compatible IR RX20 receivers can be placed into the available drop-in charging positions.

Performance Highlights

The CHG 520 supports as many as five units at one time and provides individual red LED charging indicators. Its purpose is limited and clearly defined: charging and storing Williams AV IR RX20 under-the-chin infrared receivers. The supplied specifications do not state charging time, power consumption, battery compatibility, or operation with other receiver models. Listed approvals include WEEE, RoHS, CE, FCC, CANADA, RCM, and UK CA. The charger is covered by a one-year warranty, with a 90-day warranty applying to cables and the power supply.

What Makes It Different

This model brings five compatible receiver positions into one charger while retaining an individual charging indicator for each position. That combination distinguishes it from a single-unit charging arrangement and makes the unit directly aligned with multi-receiver IR RX20 systems. The low-profile 1.5-inch height and 13.6-ounce weight are documented physical characteristics, while the black metal-and-plastic construction provides a clearly specified exterior. Because the available data names the IR RX20 specifically, the CHG 520 is best evaluated as a dedicated accessory for that Williams AV receiver rather than as a universal infrared receiver charger.

Final Assessment

For a system already using Williams AV IR RX20 under-the-chin infrared receivers, the CHG 520 provides a straightforward way to charge and store up to five units together. Its individual red LED indicators make charging status visible, and its documented dimensions allow the required placement area to be planned in advance. The five-unit capacity, drop-in format, listed electrical requirements, and defined warranty make it a practical match for managing a group of compatible IR RX20 receivers.
