    I do pay very much about what a company claim about brightness and about battery running time because

    Most of the time they full of crap

    The brightness of this flashlight is decent but the only complaint I have is the focus is a little bit crap-ee in that it is square all the way in and way out it is mostly a circle

    But the flashlight itself is worth $7.50 for what I paid for

    Now the charger that runs 110 ac voltage is worth maybe a $1.00 that’s for the charging power cord for it plug to charge the battery

    Now the 12 volt car charger is only good for the cord same as above

    The battery worth I have not determined as of yet
    Because I have not tested it completely

    But I am going to remove the heat shrink tubing that on the battery then I will know more
    Here are some pictures of the switching power supply for this flashlight

    I have a use for this switching power supply I going to run some LED lights off it it says 4.2 volts @ 500 milliamperes

      i doubt that will pass a hipot test.
      not enough separation.
      no opto either.
      no cc/cv charge control.
      it just floats the cell at 4.2v
      thats a nono for li-ion.
      kill it with fire before it kills you with fire!

        As you can see there is NO protection board any where on this battery

        They are trying to hurt someone with this crap really

          This is why it going to get a 0.500 milliamperes in-line fuse on the input
          on these two switching power supply and use some real cheap LEDs so I do not care what happens to them I want to see some carnage some smoke and maybe some fire but I do not think I going to get that lucky
