- It can be used as a power connection cable for various electronic products such as multimeters, instrumentation, alarms, medical equipment, and blood glucose meters.
- Red and black two-color leads
- Line length: 12.5CM
- DC male: 5.5-2.1mm (outer diameter - inner diameter)
- After the DC male is connected to the 9V battery, the polarity is positive and negative.
Everything works great as advertised. Both connectors are very neatly made. The barrel male connector is 5.5 x 2.1mm. I hooked in a Panny 9V battery and tested the adapter with my multimeter. It has proper polarity and output voltage. I also tested it on a LED video light, it works fine with the 9V battery and provides enough power. My only complain is the short cables.
Leads length is 12.5cm which is very convenient. I have been using it for powering my multimeter by AA batteries or by wall power adapter. The multimeter works perfectly as it is powered by a 9V single battery. It is great as an 9V power cable accessory for general purpose applications.
