I have an older wireless speaker set that uses 9V at 1.5A. I wanted to use it with a 5V USB power bank, and this adapter does just that: converts 5V USB power to 9V power. It handled my speakers without issue.Lots of tips for various applications.

Fits as good as a OEM plug at less cost.

They keep sending the wrong item. The one I ordered has one less cable end than the one I bought. The replacement is the the same wrong item. However, one of the ends is the one I need.

Returned it because it did not fit

Exactly as advertised. Nice assortment.

So many options are available with that extension cord that we can charge almost any device. Love ❤️ it .

The listing claims "DC 9V 1A 2A", but it is not capable of any more than 300mA.I used a calibrated Keithley 2460 SourceMeter to apply precise loads in 100mA increments. It began to current limit and drop below 9V with loads greater than 300mA. With a 500mA load, the voltage had dropped to 7.1V.The listing is wrong, and is false advertising.

I use the SUPERBOX to watch TV in my wife's "She Shed" and there is no power out there, so I used this cable to run the SUPERBOX off USB power and it is perfect! Use this to run any 5V household electronics off USB power, you will be surprised how many things can run off USB.
