Can you use them with solar powered equipment

If you mean can the charger be used with a solar panel then yes I do this when the sun is out, it has a USB phone type charger socket, not the C type.

if you have one of these - ‘Roughly’ how long does it take to charge the AAs that come with it (nothing else) from flat?

It depends on your battery capacity and wall charger (adapter) specifications You can send them to the customer service mailbox Address: bobi.wu@tuomantech.com We will analyze for you

When charging one of the battery side light is blinking in red. Any reason?

The red light flashes when the charger is charging, it means the battery is broken/the battery is not rechargeable
