    (uploaded by trizic) fits in an ipod sock quite nicely. GET YOUR DX IPOD SOCKS! (uploaded by trizic) Comparison to a microsd to SD adapter (uploaded by trizic) Look at my hand, i guess when DX said the package contents were LED lights, it was true

    Ownership verified by DX Not a bad buy
    Posted by crimsonjade on 9/7/2008
    Involvement: General (knows how to use it) - Ownership: 1 week to 1 month

    Price: starstarstarstarstar
    Ease of Use: starstarstarstar
    Build Quality: starstarstar
    Usefulness: starstarstarstar
    Overall Rating: starstarstarstar

    Pros: I bought this for my brother and he hasn't any complaints on it. It does what it says it does, what more could you ask for?

    Cons: According to him, the jacks are a little loose, but that's to be expected with a few of these. Other than that there isn't much to complain about.

    Other Thoughts: In my opinion, could use a few other colour choices for the choosiest of us. Black is pretty plain, but as to functionality, again, there really isn't much to say.

    Bottomline: It works. Really, just get it if it's something you need to use often. The price is great for what it does, and even if the jack's are a little loose, you won't cry over it for what you've paid for.

    Ownership verified by DX As advertised

    Involvement: Expert (understands the inner workings) - Ownership: more than 1 month

    Price: starstarstarstar
    Ease of Use: starstarstarstarstar
    Build Quality: starstarstarstarstar
    Usefulness: starstarstarstarstar
    Overall Rating: starstarstarstarstar

    Pros: -Capacity is just as advertised-I've measured 2240mAh,but it was using the 5v output and doing the math to discover the capacity at 3.6v;there is some loss after stepping up the voltage.
    -Easy to use,just plug the usb cable on it and turn it on.
    -Works on almost any device,ALMOST

    Cons: -Doesn't work with my Microsoft Zune,it detects it was plugged in somewhere(it turns on automatically),but the battery is not charged.
    -Energy per weight is pretty low,li-ions can achieve up to 270Wh/kg,this one has only 120Wh/kg,the stepping up circuit and usb connections add some weight,but it still could be better.

    Other Thoughts:

    Bottomline: Useful product,remember to get usb cables for the products you want using with it,or adapt by yourself.

    Price: starstarstarstarstar
    Ease of Use: starstarstarstarstar
    Build Quality: starstarstarstarstar
    Usefulness: starstarstarstar
    Overall Rating: starstarstarstar

    Pros: -very cheap!!
    -very small!!
    -can be easily fit into you pocket and you wont feel that its there
    - pretty high capacity, 2400mah
    -LCD lighting tells you when its charging or not.
    - An on, off switch that manually allow u to turn it off to save power

    Cons: -output only limited to 450mah which doesnt charge my sidekick b/c my fone require higher voltage and current
    -charges my ipod pretty well

    Other Thoughts: -check to see if it works for your appliances to see if its compatible.

    Bottomline: great item and its very cheap!!!
    only con is its output doesnt really suits me

    Ownership verified by DX useful at times

    Price: starstarstarstarstar
    Ease of Use: starstarstarstar
    Build Quality: starstar
    Usefulness: starstarstarstar
    Overall Rating: starstarstar

    Pros: -cheap
    -easy to use
    -compact
    -lightweight

    Cons: -does not work with everything
    -usb power input is hard to get plugged into computer unless you use the cables provided

    Other Thoughts: It did not charge the new ipod touch at all, so if you're thinking of it, better get something else. Works on phones and usb gadgets.

    Bottomline: Good for the money but won't work with everything, possibly because it's only 450mah output? I'd get something a little better though if I had to buy again.
