Thanks you helped me alot, because yesterday we had loadshedding from 20:00pm to 22:00pm and then we had loadshedding today I think from 10:00am to 12:00pm and I am in grade 10 with a online homeschoolling program and I need something to keep my pc and router on untill I finish my work. So maybe...
My budget is around 2000 to 4000 so maybe I could get a inverter with a battery combo for that price, I saw one on Pclinkshop.co.za that was going for around R4500
