> most interest

Which voltage regulators work with them so they will keep a storage battery charged
(including intervals of shade and overnight (do they return to charging after an interruption))
while you attach and charge and remove your mobile (phone, camera, flashlight) chargers/batteries.

Look at the common run of reviews

I can test a couple phones and a couple battery banks as interruptions occur… I understand apple products can be picky about intervals of shade and sun, so that could be interesting.

Can you be a little more clear about the voltage regulator suggestion? I dont have much in the way of testing equipment, but I do have a cheap usb charge monitor.

One thing I found interesting is what happens with extremely gradual power ramp up, like what you get when the sun is rising. Some electronics just freeze up.

For what it is worth, I noticed this charger on sale on amazon the last couple of days.

This site does a good job of tracking Amazon’s wild price swings and gives some price history.
This one’s not in stock right now (actually nothing from Aukey seems to be, but that can change fast or your results may differ)

Note the very brief low price spike.

Narrow it down to something Amazon says they have in stock, or follow the 3rd party price links — this finds far more than that:
