45W

had a cold water circulator for after knee surgery but couldn't find the power supply. 7.5 volt with small plug. this works great. a little overkill but its been running 6 weeks without a problem. the OEM replacement power supply was way higher price if i could find one. this will be very useful even after i quit using the machine.

works perfectly

Good power supply. I was able to use the universal connector to bring my label printer back to life.

Provides multiple tips and multiple voltages. But has a fixed polarity DC positive pin. The cord is decently long and the adapter itself is smaller than a laptop adapter but bigger than a wall adapter. It has been powering an elliptical that had its adapter lost during a move. It has had zero problems powering the panel, fan, brake and processor of the elliptical. The voltage output isn't terribly accurate at ~5% off. Compared to name brand adapters running 0.05% variance. I wouldn't trust this adapter with any kind of highly sensitive voltage requirements. A short device life would be the result. I would have been much happier to see this at around 2% or lower but its not like they are building these with quality in mind. They are built to a low price point. If you want better voltage tolerances, spend more and get O.E. Otherwise, this multipurpose adapter should do the trick for most needs.

Looked and looked for a power supply that would do 13.5 VDC and this did the trick. Powers my fiber based internet board.

Verified the power output DC voltage at plus .23 volts.. in tolerance. Great little devices.

reasonable operation

I needed a charger for a wifi speaker which took a very small pin adapter which none of my usb cables had. This charger came with so many adapters I would be surprised if I ever needed anything else. The value , quality, and shipping from this vendor is outstanding.
