Coronavirus advice sought. Say the mains electricity goes off for a long
time. What is the best solar rig-up for charging batteries for my radio,
music player, electric toothbrush, and torches? I won't need to charge more
than six AAs or four Ds at a time, but a bit of redundancy wouldn't go
amiss so that I can help out my elderly neighbours. Most important is the
radio.

Some kind of simple setup, say with a single panel producing 12V connected
to a 12V battery charger if they exist would be preferred, but I am open to
all recommendations!

Thanks in advance,

Harry
