  • Great DVR, but could be better

    posted by Cythrelo

    Excellent quality wide-angle video (front and back) and audio. You can set the DVR to record the front camera, the back camera, or both simultaneously. Videos are perfectly gapless, so you won't be missing one or two seconds every time the video splits. High quality, bright screen, and good quality suction cup for the DVR.The user manual's English translation isn't great, but it's good enough - certainly not gibberish.
    Thankfully, the cable for switching to the rear camera when you shift into reverse plugs into the rear camera itself, not the DVR. This wasn't mentioned anywhere in the description, and I was wondering when I ordered it.
    Very good deal for the price, and it's nice knowing that I'll have recordings of both the front and the back if I ever get into an accident.
  • Good, would buy again

    posted by rndoja95chbx4

    Does what it says. Get about two full charges (from flat) on my Galaxy Note 1.
    Dubious about the 20,000 mAh rating, but these are often exaggerated on these types of products. Even so it does has a 'decent' capacity. I seem to get two full charges(from flat) on my phone (Galaxy Note 1). Takes at least a few hours to fully charge (I just leave it overnight). Gave ease of use 4/5 simply because it didn't come with instructions.
    Would buy it again. Yet to see how long it lasts, but to be honest I don't use it that often. Seems to work well and and capacity 'as good' if not better than expected.
  • 3 x 18650 Battery Dual-USB Power Case Kit

    posted by nocchid

    I purchased the item in use and recycle batteries replaced the notebook, with solder terminals, I will check the batteries, I try and connect 3 batteries in parallel, only 30 min to assemble the object.
    the pack of batteries 3 18650, ensures a capacity of more than 6000mAh, therefore 4-6 times higher than the normal battery of a smartphone, to load the package, there is the same micro USB greatest number of phones, so you need the same cable of the mobile phone,
    the case is very well built and very nice
  • Works, cheap, fun

    posted by gjbloom

    It's cheap and it works straight out of the box. The free-standing form makes it possible to peer into places you couldn't get a traditional bench-top microscope. The built-in LED illumination is very convenient.
    I compared the magnification and resolution I get using this microscope against what is possible using the macro zoom of my Panasonic Lumix TS2 camera. The macro zoom of the TS2 provides almost the same magnification, at much better resolution and color. Of course, it costs about 10x as much as this USB microscope. And you can't stick it in your mouth to get pictures of your fillings like you can with the microscope.
    Fun toy that might come in handy some time. You might as well get one.
  • Without any documentation

    posted by Stefan1973

    Nice powerpack, feels good in hand, feels solid but not heavy at all, so good to take with me on long walks or bike rides. Haven't tried how long the battery lasts
    Came in a plastic bag. That's it. No box. no information. It has a special cable that only fits this powerbank. Woulf have been better if it was a micro usb
    Good price for this powerbank.
