  • Powers Arduino UNO

    posted by LynnCochran

    Provides 9 volt power to my Arduino UNO, when it's not powering another high-current project of mine. The 5.5/2.1mm "barrel" power plug fits Arduinos, with positive in the center of the connector (if the batteries are installed correctly ;) I have not had problems inserting the batteries into this enclosure, but I add the center battery on each side last (and remove it first).
    Price could be a bit lower.
    If you need a 9V battery source to power an Arduino in a standalone project for a long time, this pack will do the work.
  • Works as expected

    posted by grpires

    It is very simple: just place the batteries on the holder and connect it to the Arduino. No rocket science. Perfect for running your Arduino standalone projects, losing the dependency of USB cables and notebooks/netbooks to show your project to your friends
    Nothing else to say.
    It works just as expected. Buy it if you want your Arduino working standalone.
  • Work ok for phone charging. And light ":)

    Small price.Universal USB socket allow to charge any phone with +5 V input using your own cable.No integration of cable make it more compact.Long lighting expected because of 4 AA batteries using.Switch save power if charging is not needed now and allow to store batteries in the power bank.
    Would be good to have the switch more deep in the body to protect from occasional power on.
    Good gadget for "back-up" charging of the phone.
