Unfortunately, the description for this product incorrectly states that it has a USB power port. We are trying to get Amazon to correct that. If you are in need of a universal adapter with a USB power port, try the PowerLine 0900-77 which is a 1300ma Universal Adapter with USB Power Port. It also has over twice the power capability of this adapter if you have higher demand devices to connect. If you only need USB power, then the PowerLine musicPower 0900-71 is an ideal solution and provides 2 USB power ports that can be used at the same time.

Bought 3 at this great price.

Pros:

1. Verified with a multimeter that the voltage is very accurate.
2. Used it on two of my Philips Mp3 CD players - plays excellently. I didn't hear any unfiltered buzz sound with earphones - so the filtering is good. It could, however, have been adequate filtering inside my mp3 cd player. I can't tell.
3. Replaced my current cable modem power adapter (which is the non-switched power adapter, big, heavy and mildly hot when in use, and its output voltage is 17volts without load than the labeled 12volts). My modem works great and the power adapter is cool (not even mildly warm).

At this price, it's a great product for replacing lost/broken power adapters. Also saves energy/$$$ for non-switched adapters for long duration use.

As a rule of thumb, at $0.10/kwh electricity price, a 1 watt non-switched adapter plugged in 24 hours a day for one year will cost you exactly $1 per year. A typical non-switched power adapters has no-load power consumption (energy waste) of 5-10 watts . That would cost you $5-10 to have it plugged in for one year.

For my cable modem, which is plugged in almost 18 hours a day, consumes 12w when measured with a Kill-a-watt device, energy savings in a year and a half would pay for the adapter itself. Not to mention it would not make the room hotter. ;-)

Cons: input is 120v only. It would be much useful to be a 100-240v input. I strongly recommend add this feature. It would cost so little but making the adapter many times more useful for traveling.

You can use this AC adapter for a variety of electronic gadgets, eliminating the need of disposable batteries. It is not a charger and hence not for devices with rechargeable batteries. I bought one of the same brand in a store over 1-1/2 years ago and it is still working perfectly. So I expect this new one to last awhile.

There are 5 voltage settings: 3V, 4.5V, 6V, 7.5V, 9V, and 12V. It comes with 7 interchangeable plugs of various sizes, secured in a storage bar. There is a "Plug Tips Storage" box attached to the adapter. It slides in and out of a slot on the side. The storage bar, with the plugs attached, does not fit into the storage box. To use the box, you have to remove the plugs from the bar. A green light turns on when the adapter is plugged in.

Before you install a plug onto the cord, you need to find out the polarity of your device; it is either tip positive or tip negative. You can usually find the information right next to the power socket of your electronic device. Install the plug by lining up the + or - symbol with the word "Tip" on the plug receptor of the cord. The wrong polarity may harm electronic gadgets with delicate integrated circuits. It is, therefore, best to obtain the polarity information ahead of time.

I needed a power adapter for a portable CD player that I used at work w/ speakers. I wanted to get it cheaply. This fit the bill, and has worked without problems. I simply selected the voltage (which was indicated right on my player - it should be printed on most electronic items, so don't guess) and picked which plug fit.

The ac adapter serves its need. It's compact and light. However, it doesn't have the USB port as described by Amazon. The 600ma comes in handy as I have tried a 300ma model that won't power up my infrared device trash can. The storage on the side is a nice touch to store all of the unused tips. It's too bad that it doesn't have the USB port.

We ended up not needing this for the item we bought it for, but kept it anyway because its just great to have around. Can power just about anything that has this type of AC adapter.

The price is right and it's nice that it comes with a little container to keep all the plug ends in, but..... This thing emits a ton of electrical noise. I tried to use it to power a wireless radio transmitter to a gaming chair, but the sound ends up with a buzzing noise. Batteries work fine and an AC adapter I borrowed from another appliance works fine.

I bought this to replace the supplied power adapter that came with my Panasonic CL20A network camera. It works so well that I bought another one to use it with other devices. The supplied plugs fit a variety of devices, you definitely find one that fits! It has been 6 months and they are still working great!!

I removed the attached storage box because it is useless. The cover is difficult to open and it makes the adapter larger and awkward to attach to any multi-outlet.

But I am very happy with it. It is made in China (of course), but it is of good quality and will give you good service for a long time.

This unit is fantastic. Not the best quality but for the price does the job very well. I used it to replace the adapter on my router, charge my electric screw driver and power up some old electronics. Fantastic value.

One of my gadgets required inverse polarity - and this really handled it very well.

Will buy another for sure.

I am very pleased with this Universal Adapter. It came with several different plugs to accommodate many different small electronics. Additionally, it comes with an attachable pouch for storing the the extra plugs. The delivery was very quick and the price is very affordable comparable to other stores I checked. I would highly recommend this item.
