Loved the simplicity . just connect it . and it just works! No frills . no nonsense!
Tip: I had actually bought it to provide power backup for my Aquaguard RO ( water purifier) unit . I think it was wrong as it didn’t work. ( I guess because it’s an electrical device with motors and all . and not an electronics device.) I then connected it to backup my electronics stuff ( FTTH modem + WiFi router + wireless telephone) and it just works! I even tried it for my 40-inch LCD TV + Home Theatre . and it worked like a charm there too!
Note: Please carefully calculate the power ratings of the devices you connect . and DO NOT overload at any point of time.
