5V 2A Regulated Switching Power Supply (110~220V)

Pros: This unit is very cheap. I bought two units. The soldering quality on one is very poor an d it will need tidying up before use. I made a power supply for a radio with the other and it performs flawlessly.

Cons: The mains wiring label is incorrect on the unit as supplied to me. The label has the legend L I N which I assume stands for Live Earth Neutral. A check with my multimeter showed the case is connected to L which is a potentially lethal error. The Label should read G (ground or earth) P/L (phase or live) and N for neutral. Do not connect the phase wire to L because this will make the case live.

Other: If you trust yourself to wire up a circuit safely this is device is awesome value, otherwise look elsewhere for a wall wart.

Pros: Small, metal housing. Cold without a load at long time. Easy to connect to external circuit. Have surge (coil and capacitor) at input. Good voltage stabilisation on load from 0 to 100%.

Cons: Bad assembly. Some metallic elements have traces of rust. Some elements installed not good.

Other: Normal power supply for electronic devices.

Pros: Compact power supply unit good to tuck into other projects Adjustable voltage output allows fine tuning to the load

Cons: Labeling is confusing because the separator looks like an 'I' but is correct. Some metalwork a bit imprecise but does not affect functionality

Other: Works as it should and is inexpensive.

Pros: i search a power for my foscam clone camera available on dx , because after 3 months the power adapter really fire up itself so i try tis modl el and now i make a new order for all of my 5v needing materiel because it runs correclty the current is stable and you can pu this in a pvc or aluminium box and it 's ok , with some hole for the heating but he good thing is the power doesn't come really hot less than a plastic 5v converter like for gsm charger or somethnig like that but if u need 5V 2A power converter buy this one i also command the 12V version for try with my french freebox (adsl modem router)

Cons: nothing when you know what is current and gnd, mine arrived correclty connected gnd is gnd , L is pahse and N is neutral everything is correct

Other: none

Pros: Very inexpensive. Perfect for DIY projects. Nice and small. Surprisingly stable output. Trimmer on the output level came in handy when getting the voltage to spec at the test points on my Raspberry Pi.

Cons: It looks like it was put together in a hurry, which I guess is not surprising given the price, but it works well. I would prefer a screw on top rather than the snap on top on the case but at the price point that may be a lot to expect.

Other: If you are a DIY type looking for an inexpensive 5V power supply for a small project it is very hard to go wrong with this unit. I would recommend it to a geek friend, but I wouldn't recommend it to my Grandmother. ;-)

Pros: Small, very compact. Works in 110Volts to 220Volts. Output stable. Trimmer for voltage DC adjust. Cold till after many time of use.

Cons: Assembly not so good,may be best. Needs a multimiter to adjust, if necessary to your project. Maybe needs a expert to wire up(AC and DC ) if you don't know what are you doing.

Other: Do the job well. Very recommended for DIY projects , if you know what are you doing.

Pros: - Great value for money - Has a regulator to allow adjusting output voltage from (in my case) 4.5V to 5.5V - Small - Convenient holes for easy access to connectors and regulator

Cons: - Housing assembly could have been a little better if the top cover was bolted instead of snapping in.

Other: Would buy again without hesitation.

Pros: Relatively inexpensive, and a useful product for DIY projects or replacement of power modules. Easy to use, and reasonable available (nominal) power. There should be no problems with heat dissipation.

Cons: None that I’m aware of, as long as you treat it carefully, because voltage adjustment is a bit fragile and the variable resistor is misaligned with the access hole. Don’t let it exposed if you have kids around, as there are holes and openings (and there is high voltage inside).

Other: Have bought a second one, after using the first I bought, so ...

Pros: - works fine - no influence on hifi system as some other switching power supplies do - good connection terminals, 0,75mm² cable fits (and more than enough for 2A)

Cons: - could be a little bit smaller - cut outs in the lid are not very good aligned - to adjust the voltage or screw on the terminals, you have to remove the lid - protective sheet was on the lid and then the stickers marking L, N, PE, +, -, were fitted. Remove the sheet and the stickers get lost.

Other: The production process of the housing could undergo some improvement, but once installed, it works fine.

Pros: -Cheaper and more current than USB chargers for DIY project. -Very small. -No heat under load.

Cons: -The metal case is not the safest thing I ever seen but is good for integration project. -Connectos can be a bit small depending on your AC cables.

Other: Very decent 5V power supply. I recommand it!
