5v power supply Customers Reviews

  • Polarity reversal

    posted by advanced4

    Multivoltage, multi output voltage, numerous tips, compact.
    Compare cord and tip set with SKU 33874 and SKU 15249. The above 2 SKU's come with a European AC plug though.
    If the center pin of your DC in jack is (+) then you should be fine.
  • Perfect for a lot aof devices

    Excellent quality. Really well done and works great as I expected.
    I bought it for my multimedia hard disk and La Fonera router that have the faulty power supply and it works fine.
    If you have a router, surveillance cameras, switch, mediacenter, electronic equipment or other devices that need to run 5V and 2A this is the right choice. Beware of the connector to be 5.5 x 2.1mm for your device.
  • Really small!

    This is a really small switching power supply!!Line side has a varistor, thus some kind of surge suppression is provided.Output voltage: 5.10V (no load)When no load is attached, a witched power supply draws about NOTHING current. Ideal green replacement for those old bulky transformers.
    Still didn't measure ripple at maximum load (will put results soon), but according the specs it is around 150mV (according the specs it is 150 mW, but that is probabely a bug...)
    Nice, cheap and small switching power supply.Not worth making one youself......
  • Nice power supply for DIY electronic experiments

    posted by Sassa53

    Small, very compact.Works in 110Volts to 220Volts.Output stable.Trimmer for voltage DC adjust.Cold till after many time of use.
    Remenber that you needs the wires( to AC and DC) and plug(AC) and a tool for adjust.
    Do the job well. Very recommended for DIY projects , if you know what are you doing.
  • Good 5v power supply.

    Easy to calibrate via built-in adjustable resistor.Extremely light weighted and small sized for it's current level. Built-in led allow you to see whether the supply is switched on or not.Input and output contacts are easy to use.
    Very suitable to a lot of DIY projects with external 5v power supply.
    I'm going to bye at least 5 more. Very useful and well done. I was rwally surprised how light and small it is.
