9V Battery Snap to 2.1mm x 5.5mm Male DC Barrel Plug Adapter, 20 AWG | RC-9V-2155

9V-Style Battery Snap to 2.1mm x 5.5mm Male DC Barrel Plug

WARNING: CONNECTOR ADAPTER ONLY, NOT A VOLTAGE CONVERTER OR BATTERY CHARGER

"9V" identifies the battery snap connector style; this cable does not create, regulate, or guarantee a 9V output. Verify the connected battery or DC source voltage and the polarity at the barrel plug before connecting equipment. Incorrect voltage or polarity can damage equipment. Do not use this cable to charge a battery.

Part RC-9V-2155 connects a compatible 9V-style battery snap connection to a 2.1mm x 5.5mm male DC barrel plug. The barrel end is a plug that inserts into a compatible equipment socket, not a female socket that accepts a power supply plug. This short adapter uses 20 AWG wire, a 2-inch cable, and a battery snap with a soft plastic cover. No soldering is required.

Intended Use

Use this adapter to connect a compatible battery or DC source with a matching battery snap interface to equipment accepting the male barrel plug, only after confirming the equipment's voltage, current, and polarity requirements. A matching snap or barrel connection does not establish electrical compatibility.

CHECK OUTPUT POLARITY BEFORE USE

Do not assume center-positive or center-negative output from the connector shape or wire colors. The wiring polarity has not been verified for this listing. Measure voltage and polarity at the male barrel plug with a multimeter before connecting equipment. Do not connect an external power supply to a battery through this cable.

Technical Specifications

• Equipment connection: 2.1mm inside diameter x 5.5mm outside diameter straight male DC barrel plug
• Wire gauge: 20 AWG
• Cable length: 2 inches
• Function: Battery snap-to-barrel connector adaptation; no voltage conversion or charging control
• Polarity: Verify at the barrel plug before use
• Installation: Plug-in/snap connections; no soldering required

Compatibility Checklist

• The equipment requires DC power at a voltage compatible with the connected battery or source.
• The battery or source can supply the equipment's required current; connector fit alone does not establish capacity.
• The battery/source snap interface mates correctly with the adapter.
• The equipment accepts a 2.1mm x 5.5mm male barrel plug with suitable insertion length and clearance.
• The adapter assembly's allowable voltage and current are verified for the installation; 20 AWG alone does not establish a complete assembly rating.
• The measured barrel-plug voltage and polarity match the equipment documentation.
• The connection is used to supply compatible equipment, not to charge a battery.
