Shawn Randeny (verified owner) –
I bought the Omega Digital UPS LI-850 600W and am very happy with the product. ( https://hardwaremart.lk/product/total-power-solutions-600w-omega-digital-ups-lithium-inverter/ )
Customer service – very good and prompt service with step by step updates since it was a online purchase. Apart from few delays in the website registration which the staff (Kalindu) sorted out quite quickly.
Online experience – very organized and again staff helped me navigate and give the products i needed with all of the technical specifications.
Product – the product is compact, well built with a digital display indicating the Main lower status, battery voltage, Charge Amp, grid voltage. The product provided power to my Laptop and Dell monitor plus a desk lamp and few other mobiles being charged for over 9 hours and it still got plenty of juice left in it. Noice -less operation and fully functional. The switch over from grid to battery is effortless and happens within milliseconds. Total battery capacity is 84Amh and my usage was closer to approx. 75W. According to my calculations this product can power up a Laptop, Fan, Monitor, phones and last up to 13 hours.
I have attached few pictures for future reference. Thank you for the positive experience.
