    Anyone know if this would fit the annoying and short Xiaomi TV3 box?

    •  

      Yes it will but I think it won't be able to supply sufficient current at 5V that is required by Mi Box.

      • +2 votes

        If the Mi Box is anything like the other boxes that run on that chipset it should need 2A max so this should run it alright. Someone with the hardware could confirm :)

        e: Alternatively you could buy a Blitzwolf etc USB charger and make up a USB>DC barrel power cable and save like $3!

        •  

          I have a Digitor one from Dick Smith. The max current applies to lowest voltage.

        •  

          mibox didn't work on 5V (original 5.2). I just got a white screen so the 0.2 must be doing something.

        •  

          @gimme:
          Working fine on my miibox.

          The power pack does make a whining noise though which I'm not too happy about

      I'm using one with no issues with my Mi Box International. Blue LED is annoyingly bright though.

      •  

        Just what i wanted to hear.

        How long is the cord on these ones, i cant find it mentioned in the ad

          I have no idea, sorry. I have the power board sitting about a foot away, so my issue is more trying to hide the extra cables.

      According to the website the power details are the following: Power input: 100~240V 50/60Hz input, 5.2V, 2.1A output. A 5V charger will be within the tolerance. Seems that there's enough current to run it by itself, but "when you start replacing power supplies for ones that output a lower Amperage expect 2.5" USB HDD & peripheral problems."

      EDIT: Just read the comments below, it provides 2.5A at all voltages which is great. It should work with MiBox in that case.

  •  

    Would the available max 2.5A current drop depending on what voltage is used?

    Used to be such a 'must-have' thing around the house. Can't think of any use for it around my place now. But will have to buy it I guess in true Ozbargain spirit.

    The 3 pack says 2.4A and the single says 2.5A

    Typo?

  •  

    Anyone know if this will work with a 3.5" WD external HD?

    My power supply made a loud pop and crapped out on me a while back

    •  

      So long as its a single voltage PSU, not a 5/12V one should be fine, checking the output rating on the old PSU is the only way to be sure.

      •  

        Oh okay thx.

        I was a bit my concerned on whether or not the tips would fit in though

        •  

          I'd say the included tips would cover it, but I'm really just guessing since I have no idea what model HD you have. One of the 3 on the right of the pic should do it I'm thinking.

  •  

    If you have a $5 off $10 spend ebay code the single is available here

    Also, these things should also come with USB tips these days.

    •  

      Good point. Do you know if/where you can buy just the USB tip (to connect to the end of the cable)? Most of the ones I can see on eBay have a separate USB-A female port to connect the USB cable.

  •  

    Any good for laptops?
    Thinking about a laptop charger I lost for an old Lenovo

  •  

    Nice! Bought 3 as well. Will be useful for various projects.

  •  

    Anyone from Box Hill Victoria requires one , I will buy three , but I need just one comes to approx. 6.40 AUD each if we buy 3.

  •  

    Thank you OZBARGAIN . I just get one.

  •  

    Pardon my complete ignorance but will any of the pins be compatible with the Acer Chromebook 14? I've found the specs for the charger here but am clueless as to whether it'll work or not

  •  

    Up to 2.4A not 2.5A…. and to be honest safe current for that power adaptor is 2A for voltage above 7.5V

  • +1 vote

    Bought last time so won't be buying anymore, but recommended if you're after this sort of thing either as backup adapters or for electronics projects. Significantly cheaper than Jaycar given the power output (not that Jaycar is hard to beat lol) and these have proper AU plugs and compliance tick compared to equivalent priced eBay ones.

  •  

    doesn''t everyone have a big box of random AC/DC adapters?

  • +3 votes

    A slight caution; these adapters are rather blocky. On my general outlets at home, having this plugged in blocks even a regular circle plug being plugged into the adjacent socket.

    Got a hacksaw and cut off the side bits which are just hollow plastic bits and that "fixes" it.

    Can I use this for a Raspberry pi?

    •  

      Pi is powered via micro USB, although it can provide enough 5V power, this does not have a suitable adapter.

    Not sure what for, but grabbed a 3 pack….

    Found the checkout process a little difficult. It said I could log in via facebook but that never worked, so if you're having this issue. Just sign up the old fashioned way.

  •  

    Thanks, got the 3pk. They're really handy for DC powered things that use can use batteries, but didn't come with an adapter
    Better than wasting 6 precious AA eneloops :p

  •  

    You reckon a Dell laptop would charge with this? I have a work one and sometimes need to charge it.

    Didn't know I needed this before today. Damn impulse buys.

    Why did the deal I posted get marked as expired? Not mad - just asking so I know for next time…

    • +1 vote

      The System automatically expires deals after 45 days have passed (90 for freebies), if you don't have an expiry date put in already. Then the comments are closed too.

      It can be overridden if you put in an expiry date yourself.

    •  

      seen your deal last time but was worried that higher voltage is lower amps. Since many has confirmed it's 2.5A for all voltage should be good.
      Just a bit strange though

      normal other multi adapter is
      3V, 2.5A
      5V, 1.5A
      6V. 1.25A
      7.5V, 1A
      9V, 0.83A
      12V, 0.625A

      i.e. Max W = 7.5W

      meaning DSE selling a 30W (12x 2.5A) for 9.90 ? that is cheap

      •  

        very unlikely due to ohms law
        The Amp/Voltage relationship you listed above is much more probable

        •  

          It's not impossible. It could easily be 12V @ 2.5A and 3V @ 10A.

          Jaycar also offer a 27W plugpack with similar specs; are they lying too?

        •  

          @kevlarman:

          Expensive adapter would have each terminal with different resistor rating
          and the adapter itself is rated 30W

          but at 3V, higher rated resistor is used, i.e. Jaycar adapter is heavy and expensive.

          cheap adapter will have the rating I listed and light weight

        •  

          @kevlarman:
          The suggestion was that it's 2.5A for all voltages.
          Its not likely due to the manufacturing requirements and is a pretty pointless goal to design for. Its possible, just not very likely. Unlikely ≠ lying

        •  

          @King Tightarse:

          Well just received my 3 adapters and the blister back clearly states "2.5A maximum output aceoss the voltage range" and "max. output pwer: 30W."

          Only time will tell!

        • +1 vote

          Not due to ohms law but due to voltage regulator heat dissipation. In the past it was a step down transformer followed by a rectifier and smoothing capacitor then a voltage regulator. These days power packs contain a switching mode power supply, which is a rectifier at the mains side followed by a high frequency oscillator driving a switching transistor feeding high frequency AC into a much smaller transformer, then another rectifier and smoothing capacitor at the LV side. In this much more efficient and flexible design, the capacity is determined more by the heat generated through inefficiency. So it's entirely possible to design a pack that maintains the same current at all voltages.

          Why high frequency? The size of the transformer required reduces as the frequency increases.

        •  

          @kevlarman:

          yeap got mine today, stated it is 30W, so it's a bargain

          unlike some cheap one is only rated at 7.5W or 10W (i.e lower amps at high Voltage)

  •  

    Anyone in Melb (CBD, SE suburbs) buy a 3 pack and looking to sell one of them? Missed out on the deal and would be keen to grab one

  •  

    FYI, these have been this price for months now. I got the 3 pack when they first got cleared out (needed stuff to fulill up in to my DSE Zapcatcher powerboard along with the Sangean and the Rarsound base)

    They are OK, first thing I did like someone commented above is saw off the pointless side plastic bits so they fit side by side on a powerboard. (http://images.imagebam.com/4b/93/6a/47843f579265343.jpg) provides 2A at 5V but less at 12V on a constant basis as it gets pretty hot, they make a slight squealing noise when there is a low draw and the blue Led (Sharpie it to dim it)

    •  

      My Li-500 battery charger requires 12V 2A adaptor anything less than 2A and it switches off when I try to charge on its highest setting, so I'm assuming this DSE adaptor can pump out 2A @ 12V or am I totally mistaken?

  •  

    9 volt 600 ma ? korg effects processor.

  •  

    used this on a mi box and the mi box was making a squealing noise as soon as it was powered on, wouldn't recommend for it.

    •  

      No squealing here but all I got was a white screen.

    •  

      I just picked mine up and I first noticed the squealing in the power pack.
      Then reading your post you said the miibox.
      I checked and I am getting a squeal from both (mainly from the power pack though)
