  • simple USB consumption measuring

    posted by mkobylan

    looks like standard USB flash memory so you should not have problem to push it into any USB port0.1A 0.01V measurement resolution
    producer should think of next generation with different display module
    it's too long so device you are connecting is bending/pulling USB port down - I would rather buy something smaller (I don't need digits 9mm high)
  • Good powerbank for reasonable price

    ?????? ???????? ???????????? ? ???? ????????? ? ???????? ??????!Just put in 1-6 unprotected 18650 batteries, close it and you have powerful powerbank.It works with different types of devices, unlike some other powerbanks, that dont support for example Sumsung phones.
    Seems, that there is no passive discharge, but cant be completely sure.? ??????????? ???????????? ?? ????????? ??????? ????????. ???? ? ??? ???? ?????? 6 ??????? 18650, ??? ????? ??? ????? ????? ??????? ???????? - ??? ???????????? ???????????.
    Good for me. I can recommend to everyone!
  • Excellent product for that price

    - Cheap- 2A output- PCB contains battery protection circuitry (deep discharge, overcharge, short circuit)- Bypass diode from input to output- Step-Up converter efficiency of 70-80%- Trickle charges deep discharged batteries- Doesn't start charging if battery voltage is above ~4.15V- Fuel gauge isn't all the way off (but tends to be a bit too optimistic)
    Some data points:- PCB looks like the 2A output version, bottom picture here: http://i1138.photobucket.com/albums/n525/yulunyan/55.jpg- Battery charge completion: 4.20V- Powered off battery discharge current: 0.5mA- Powered on (idle) battery discharge current: 4.6mA (including LED)- USB output voltage (idle): 5.21V- USB output voltage (3.55V battery, 1.63A load): 4.57V (efficiency at this point: ~72%)- USB output voltage (4.1V battery, 1.75A load): 5.16V- USB output voltage (4.1V battery, 1.95A load): 4.61V
    Awesome product for that price, apparently well-engineered electronics.I'm really curious what that jumper on the PCB is good for.
  • Great gadget for geeks.

    Simple, relatively small and primitive to use.Accuracy not tested, but looks usable.Clear plastic case looks great.
    Symbols: u means U, A is A.Waiting for your favorite number is ugly.Will be nice to select/switch display mode by button and use full 4 digits for V and A measurement.
    Microcontroller processor can't be identified, has no label on case.I will try to reprogram it.
  • Charger for fake controllers?

    posted by PransFenders

    When i bought this charger station it charges 2 controllers at once while i connect it to my computer or PS3. It work like it should. The leds are BLUE and they turn RED when i connect a controller. After some time they turn blue again.
    This station should be compatible with refirbished controllers.
    Its a good product and idea, but the problem with my charger not working for refirbished or real controller should be fixed.
