Do you have a generator? In Odesa many people with Ecoflows eventually found out they they don't recharge themselves... A 1KW gasoline generator can be had to about 300€. Expensive. But may be necessary.

I don't, but in terms of work or browsing I'm fine ) I have router powerbank for ~ 16 hours and notebook plus big powerbank, so around 16-20 hours I can spend time with notebook without supply. plus light bulbs with builtin powerbank. but little bit worried about heating system. today it is off all day and now is like 19С in my flat. It's tolerable for now, but I don't know about tomorrow. yes, gasoline generator is the best option. will see

still no electricity btw, 12+ hours
