What it is

The Listen Technologies LA-421 is a single-port USB charger delivering 5.0 VDC at 1000 mA. It is built to charge Listen Intelligent portable products and works with all iDSP devices. The compact black design suits personal use or smaller venues where a simple, reliable power source is needed.

Build and connectors

The unit accepts 100-240 VAC at 50-60 Hz, so it operates on mains power worldwide without a separate adapter. Its compact shape prevents blocking adjacent outlets on a power strip or wall socket. The lightweight construction makes it easy to store in a bag and carry between locations.

When to choose it

This charger replaces a lost or damaged original supply for Listen iDSP equipment. The jump is worth it when you need a dedicated 5.0 V 1000 mA source that matches the manufacturer’s specification. It is not for users who need multiple simultaneous ports, higher current output, or fast-charging protocols for non-Listen devices.
