    You should make it back better. First adding a good isolated 5v charger good lithium batteries then a boost converter from the solar panel to charge the batteries and an output usb to charge additional devices.

      Kind of needed the Lantern for replacing the one destroyed in a wind storm. Got to light up the stocking so Santa and/or Hogfather (Terry Pratchett Disc World series) can find it. Will post a short video within a day of it hanging in the wind.
      Will be building some solar powered Christmas globes from scratch with Ni metal Hydride cells shortly.

    I suspect the A7 diode is a shotkky type. It will have a lower voltage drop than the one in the bridge rectifier. It will make solar charging a bit more effective, though I suspect it's still not going to be great considering the tiny solar cells.

      That would be a good idea, but it is a silicon PN diode, I just desoldered it and the forward voltage is 0.602V. The A7 is the SMD version of 1N4007. I could see someone using a Schottky in there to help the charging.
      Have a good day.

    The diode on the solar cell is to keep current from the battery blocked in reverse soo not to damage solar cell

      Correct, one is needed but there is already a diode in the bridge rectifier that is performing that task. Just a mystery to me since it is rare for this type of product to have extra parts.
      Have a good day

    I was given one in Iraq and repaired it. I replaced the battery with a vape battery
    lithium

      Good way to do it. I still have not been able to find a single vape battery with all the walking I have done.

    does Santa have medical insurance ?

      At least it is all 5V DC now. My preferred voltage for displays outside since it get very wet here (-:
