12V 3.2A Power Supply Transformer for LED Light Bulb (AC 110~240V)

Pros: - very useful power supply
- it doesn't generate much heat
- adjusable output DC voltage (around 11 to 14 V)

Cons: - quiet buzzing sound
- there is no protection cap for contacts, so be very careful where you're installing it - it's easy to touch by accident 220 VAC (input) contact

Other: - so far this is an excellent power supply
- I assume if you're installing it you have some experience with electricity - so you'll know where to install it to avoid electric shock

Pros: Very powerful, well-finished, metal. It completely filled its functionality. The device is super airy with its small hole in the hull. it really is a trusted product. The product has a pilot light which simplifies visually to be sure the unit is in fonctionnemet, it's not much but super useful when testing something at the end with a switch just before his records when is what you can put your fingers in the middle.

Cons: Is a little big compared to what I thought. He will try to reduce the size even if it is not very big either.

Other: DealExtreme thank you for products at unbeatable prices with a pleasant finish.

Pros: The transformer is very nice looking. Perfect finish. Very good output! I'm driving a Black n Decker portable fridge rated in around 10A and it works perfectly! Totally silent. In my case, just a very little overheat, but I'm using it 24hs and still, it's ok.

Cons: The connector is very exposed and it may be a risk if you don't know how to handle it.

Other: Totally cool. If you're doubting, just go for it! It's cheap and very good quality. You must have some electricity knowledge to install.

Pros: The switching power supplies hold the voltage between idle and full load, good constant.

Cons: It is recommended that the equipment be subjected to a test before installation. I had 10 devices unfortunately 2 failures. Even if one calculates with, the price is still low. I opened one of the defective units to maybe find an error, I managed not with little time for now. It struck me that the quality of the solder joints is not good.

Other: I would buy the device again, but I need to provide reserve.

Pros: Have bought 4 pieces of this and it seems that both construction methods and components are of good quality.

Cons: Delivers 12V at 3.3A (tested with load) without the ripple increasing significantly.

Other: Very pleased.
