@jamesholden @happyborg @katemorley thank you. i'm grateful for your reply. i live in a flat, so it's still difficult (& beyond my financial means) to implement solar & a battery. been hoping that decent portable power stations would become more affordable; but, plug-in solar is on the horizon.
jeezo, you're paying per 57 hours what i pay for a day (in a three-bed flat that houses two adult people).
