Dear users,
Today, electricity is not just comfort for me — it is the ability to work and maintain this website. Due to the war, my home is without power for up to 18 hours a day. When electricity is gone, the internet is often unavailable, the refrigerator stops working, and much of the time I am forced to sit in darkness.
The only realistic solution is a power backup system — an inverter with batteries — costing about $2200.
Thanks to your support, $470 has already been raised — 21% of the goal.
This is an important step forward, and I am sincerely grateful to everyone who has already supported me.
I have taken a loan to start solving this problem, but covering the full cost on my own is very difficult. Every contribution brings stable working conditions closer.
If this project has been useful to you and you are able to help, I would be sincerely grateful for your support.
Support for Power Backup (Inverter + Batteries)
