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.
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

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

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 (-:
