Thanks ban


Tell me if I'm going to spend Rs. 9,000+ on a router backup, whats stopping me from buying a UPS instead?




Power bank එකේ Charge එක බැස්සට පස්සේ ආයේ Charge කරනකොට වැඩේ වාත නැද්ද?


Thanks. මේකෙ Power එකට ගහන එක එන්නේ 2 Round pin එකක් නේද? ඕක මම Electric බඩු කඩේකට දීලා, 3 Square pin එකකට කපලා කොටලා Change කරොත් අවුලක් යයිද?


Thanks


Cable eka mkkd?


උඹ ඕක Devices කීයකට Use කරනවද?

Mehemayi machan, no one is stopping you from buying a computer UPS and it will work..... but it has few main issues
1. It uses Pb batteries, which are not designed to deep discharge and frequent charge discharge cycles
2. In Computer UPS you are converting 12V to 230V and then your router adapter converts 230v back to 12v. huge energy loss

20000mAh වගේ power bank එකක් 5V to 12V කේබල් එකක් එක්ක පාවිච්චි කරන එක තමයි සරලම විසදුම.

මේ නිකන් කේබල් එකක් ගත්තා නම් ඇති ද ?
4.5V (USB කරන්ට් එක) 12v වලට up කරන්න සර්කිට් එකක් ඕනා නැද්ද

12V, 2A කරලා පවර් බෑන්ක් එකෙන්ම අවුට් කරනවා ද ? 24W support නම්
ඔය විදිහට 45W වගේ අවුට් කරන එකකට ගැහුවොත් රවුටරේ එහෙනම් කොල්ලෝ අපි ගියා කියයි ද මට
