    Initially I wasn’t convinced about the method they used for Power Saving. But I purchased one in order to test this new idea of Power Saving. Wow ! this beats my expectations. Really works !. The idea of having a Fan output is quite remarkable. I use this for my 12000 BTU inverter model. Currently using 20 minutes OFF every 40 minutes. Hoping to increase the OFF time when this massive heat goes away. Currently I am saving about 20%. Hoping to achieve their claimed target in the cooler months.

    සති 3කට පෙර 12000BTU AC එකට සවි කළා. දැනට විදුලි එකක 30ක් විතර අඩු වෙලා. මේකේ Fan option එක තියන එක පමණක් මිලදී ගන්නයි මගේ නිර්දේශය. මගේ මහ ගෙදරටත් එකක් සවි කරන්නයි බලාපොරොත්තුව .

    Next level of power saving brings this unit, if you owns a non-inverter air conditioner at home. Three adjustable timing levels. initial start up time – & repeat on time- off time. All these are user edible as he/she wishes which make the user to reach optimum energy saving level. separate fan output available while AC is moved ‘off time’.
    I personally own 18000btu non inverter damro ac and this gives 60-70% energy saving. no doubt.
    Additional protection provide by built in power guard for over voltage and under voltage. Highly recommended device for anyone who owns a non – inverter AC at home. A++

    මෙහි Fan Output අදහස ඉතා විශිෂ්ටයි. විදුලි එකක 66 පමණ මසකට ඉතිරි වෙයි. මෙයින් 5ක් පමණ එකවර ගැනීමේදී Discount එකක් දිය හැකිද ?

    I have heard about KillerWATT some years ago but was afraid to buy because of the reviews of some ‘pandits’. With the present CEB tariff hike, I bought one ans installed to my 12,000BTU split non inverter AC in Feb 2023. Wow ! what a product. After properly setting up the timing, I was able to save about 70 units from my AC per month. I use it for about 7 hours a day in Jaffna hot conditions. Well worth the money spent. Will buy more units for my family soon and highly recommend to anyone.

    මාගේ 18000BTU සිංගර් වායුසමීකරණය විදුලි බිල කා දමන්නක් බව මුලින්ම සඳහන් කරමි. කිලර්වොට් උපකරණය ගැන දැනගත්තේ මෙය වසර ගණනාවක් පාවිච්චි කරන මොරටුව විශ්ව විද්‍යාලයේ මහාචාර්ය වරයෙකුගෙනි. ඔහුද තවත් විද්වතුන් ද සහභාගී වූ සාදයකදී මෙහි තාක්ෂනය ගැන විවාදයක් ඇතිවූ අතර බොහෝ දෙනාගේ මතය වූයේ මෙය තවත් එක් රැවටිල්ලක් බවය. එවිට මගේ මිත්‍ර මහාචර්ය වරයා කියාසිටියේ, අප අතරින් කිහිප දෙනෙකුට මෙය මිලදී ගන්නා ලෙසත්, එය අසාර්ථක වුවහොත් එහි මිලෙන් අඩක් (රු. 4,000ක්) ඔහු අපට ගෙවන බවත්ය. ඒ අනුව අප දෙදෙනෙකු මෙය ඇනවුම් කල අතර එක දිනකින් COD ක්‍රමයට අප දෙදෙනාටම Deliver විය.

    දැන් මසකට වැඩි කාලයක් ගතවී ඇති අතර අප දෙදෙනාගේම ප්‍රතිපලය ඉතාම සාර්ථකය. සාමාන්‍යයෙන් AC එක සඳහා දිනක විදුලි පිරිවැය unit 6ක් පමණ විය. කිලර්වොට් QRO උපකරණය මගින් එය ඒකක 3.5කට පමණ අඩු කර ගත හැකි විය. මෙම ප්‍රතිපලය අපගේ whatsapp group එකක share කිරීමෙන් දැන් තවත් අට දෙනෙක් දින 10ක් පමණ KillerWATT QRO උපකරණය මිලදී ගෙන භාවිතා කරන අතර ඔවුන්ද පවසන්නේ මෙම උෂ්ණ දිනවල සාමාන්‍යයෙන් 40% පමණ ප්‍රමාණයක විදුලි ඉතිරියක් අත්කර ගත හැකි බවය. රස්නය අඩු කාල වලදී 70% -80% දක්වා විදුලි ඉතිරියක් අත්කර ගත හැකි බව මාගේ විශ්වාසයයි.

    එලෙසම බ්‍රාවෝ සොලුෂන්ස් customer support එක අගය කල යුතුය. මෙවැනි විශිෂ්ට නව නිපැයුමක් තවත් ප්‍රචාරය විය යුතුය.
