Product Overview
This black AC-to-DC supply has a front red-number display and rotary output-setting knob. The adapter is labeled for a 3–24V adjustable DC range and a 72W maximum, with multiple barrel tips and a polarity-converter lead pictured beside the unit.
Choose only after matching the device's required DC voltage, minimum current or wattage, connector dimensions and polarity to the exact adapter or variant label. A connector that physically fits does not prove electrical compatibility, and connector sets differ by listing and checkout option.

No universal device compatibility, brand-model compatibility, charging function, USB Power Delivery negotiation, output accuracy or stability, protection-circuit performance, certification, conductor composition, flame resistance, service life, energy efficiency or worldwide-use guarantee is claimed. Adjustable units are AC-to-DC supplies rather than battery chargers unless the received label states otherwise.

| Safety boundary |
Incorrect voltage, polarity, connector or current capacity can damage equipment or create shock, heat and fire hazards. Use only indoors in a dry, ventilated location with the specified input supply. Set or confirm voltage and polarity before connecting the device; never change a knob, tip or polarity converter while energized. Do not exceed the adapter or device rating, daisy-chain outputs or use damaged cords. |
Frequently Asked Questions
What is included?
One adjustable adapter, attached cords and the connector and converter pieces pictured for the 3-24V 72W option are represented.
How should I choose an option?
Use the single 3-24V 72W option only after matching voltage, current or wattage, center polarity and connector dimensions
How should I use or assemble it?
Read the target device label first. Match voltage exactly, use an adapter current rating at least as high as the device requirement without exceeding any stated device limit, confirm center polarity and connector dimensions, then connect with power off. For an adjustable adapter, verify the displayed setting again before energizing the device.
What checks should I repeat?
Confirm the selected model, plug, adapter body, cord, connector tips and polarity converter shown for that option. Stop use and unplug immediately for a loose fit, damaged insulation, bent contacts, odor, noise, sparks, discoloration or unusual heat; have questionable equipment checked by a qualified technician.
