I can't assume that since it's called a "premium" adapter that it is a switching power mode AC/DC adapter. Is it a switching power adapter?

Almost all power adapters of this type are switching power from AC to DC. The "premium" is just marketing hype from whet I can tell. The transformer (120-240V AC to 5 V DC) is well made. The reason I needed this transformer was the size of the plug tip. I had an LED lamp and a portable radio / scanner that needed this smaller tip size (which is + by the way). The power change from AC to DC is designated by the term adapter. A better choice of words would be transformer but you don't see that term much. I mean anything with a battery for power runs on DC (direct current). The house power you have is AC (alternating current). This AC power will be used to power the DC device and/or charge the batteries through the use of this adapter. Hope this helps.

The A/C adapter does not charge the device. It gives you an alternate power source.

Title is misleading. These units are manufactured with various DC and AC voltage ratings to OPERATE THE SWTICH; the one here RUNS on 12V DC and this power is used to CLOSE THE SWITCH when instructed by the timer; HOWEVER, the switch can be wired into any LOAD equivalent to 120V 16 amps (DC or AC). The confusing thing about the description of this switch is that the power that RUNS the switch has NOTHING to do with what you can wire into the switch, the 12V DC input simply CLOSES THE SWITCH but does NOT go through the switch.

This is NOT a converter, it is an adapter. It allows you to use US-standard plugs in a variety of foreign outlets. It does NOT convert higher voltage to 110V and you will fry an appliance unless it is already suited for 100/240 use (like most computer power supplies are). All you need to do is look at the device you need to use and see what it will handle for voltage - if it says something like 100-240V you can use this adapter anywhere, otherwise you need to get a step-down transformer (heavier and usually a bit more expensive).

YES! The AC adapter is a universal input "switching" model. You just need a prong adapter (Europlug and/or UK Type-G to NEMA-5). Specs on wall-wart: Switching Adapter MODEL:SUN-1200070 INPUT:100-240V~ 50/60Hz 0.05A OUTPUT:12V --- 0.7A (positive center polarity) I was also pleasantly surprised to find the receptacle on the fan works well with either of the two most common types of barrel plugs... both fit and make good contact, so a couple car/cig adapters I've got laying around work just perfectly with this fan. The electronics near the plug (presumably the voltage regulator) gets noticeably warm during operation on wall or car power (but not on battery power), but after a few hours, it seems to be staying within reason.

no, for that you need a power/voltage converter. this is just a plug adapter.

No there is no ac adapter. It does not require power. The switches on the front are mechanical, not electrical.

I don't get it. Why does the picture have a power cord in the photo, but then I have to buy the ac adapter separate?

Looking at the description, it says it's a surge protectory. However, I was only using it for the adaptor issues.

Yes, it should say DC not AC. Added note: I am extremely pleased with the way works.

It's probably safe to assume that this isn't a switcher type supply because of its low voltage and low current rating. It most likely has a step down xfmr and diode that feeds a 9v voltage regulator.

I looked at the back and the power supply. There is a little red switch which allows one to swap between higher and lower voltage. I don't know if this helps and if this is a standard feature. I bought this because it was a good deal.

Yes! It has a inline switch on the adapter as well! My girlfriend loves it, its been on 24/7 for almost a year now!

I'm not sure what is meant by a "standard" AC adapter. It takes a standard 6V adapter. Use a standard 12V adapter and you'll fry it. Hope that helps.

You must be kidding. This is an "adapter"attachment to an Apple voltage "converter"!

I used this on a clients setup, so I don't have it here to look at. As far as I remember it was a standard 120V wall wart type of power supply.

its a 12 volt wall adapter converts 110v AC TO 12 V dc , WHY NOT MENTION OR SHOWN , NO IDEA .
