    Great unit! I use this for travel so I can watch a movie or game while on a plane. Just keep it in my laptop bag and I always have it when I need it.
    There is an integrated kickstand. This is a VERY handy feature when using this to power through a movie.The kickstand only functions when the phone is in the unit. Without the phone the unit falls over backwards. This shouldn't be an issue since you wouldn't be using it without the phone inserted. I only mention it because DX wouldn't post this review unless I added my characters. The more you know :P
    Glad I bought it. Works as advertised.
  • nice!

    11~15 volt adjustable range.very stable voltage at sudden current changes.soldering job looks very good.
    Used the item for 4 hrs, 200W constant use (about 16.67A used)the power supply got worm after 20 min and started the fan.I would prefer the fan will be turned on all the time..would like to see 24v versions.
    if you need to use more then 250w parallel two of those power supplies.
  • Excellent product!

    this case works great it has been really useful for me it charges from a nearly discharged battery to almost 50%, you can use at any charge and doesnt interrupt your normal activities, is light and compact, the design and texture is nice and worksd exactly as adevertised
    it works great, the clip holder could be better.
  • Compact power supply

    Power supply well built, sturdy and really delivers the marked current in the case.When loads 4 amperes the voltage don't drop down.The oputput voltage are regulated with a variable resistor, is useful but not necesary.
    Well ventilated case, if the power supply is heated, you can add a little blower.You need to put some spacer in the bootom of the case, you can buy in Dx.
    Good device to mount a little laboratory or made some electronics stuff
