  • No. Just no.
    I used a similar adapter for a cordless phone, and got terrible results.

    The lack of output filtering on the AC/DC adapter caused a lot of noise in the audio.
    I tried the same adapter with an old walkman and the result was the same.
  • Im using an adaptor for my at&t wireless phone and its the same as when im using it with the transformer. so...gawing 110 na lang yung socket?
  • Like circuit1234 said earlier, a small transformer (around 20-30 watts) is all you need. Why mess with the socket and the mains wiring?
  • gaano ba kaliit yan paps? any reference pic or url? Kasi may 110 originally bahay ko. sinibak ko lang yung iba. nagtira lang ako sa kusina.
  • Not 100% sure, but small ones (<50w) can fit in one hand.
  • @all

    Guys question lang. Meron kasi akong napanalunan na LG Top Loading Washing Machine and plan ko ipadala sa Pinas (I am based in Abu Dhabi) and upon checking the specifications nakita ko na 110-240Volts and 50Hz ang frequency. I have heard alot na dapat daw 50/60Hz ang appliances para magamit sa Pinas. If that is true ano ang dapat kung gawin or bilihin para magamit yung Washing Machine sa Pinas? Thanks.
  • eto nakabile na ko awakeruze. isa muna. pag ok ang gamit bilhan ko na lang din yung 2nd handset charger ng ganito

    Ibenta mo na lang diyan at yun pinagbentahan ang ipadala mo sa pamilya mo sa Pinas para bumili ng Washing Machine.

    Kahit may malaking stepdown transformer na 110 ac outlet ay problem pa rin yun 50HZ motor ng washing machine. Iinit lang motor dahil hindi match ang ac line frequency.
  • @wakaskik - and i dont think that walang ganyan dito. kakabili ko lang ng LG top loading 14k lang. so kung may freight ka pa lugi na.
  • @circuit and phoenix

    Thanks guys. Naibenta ko na yung washing machine.. hehehe.. Yun din sabi sa akin ng LG na gagana naman daw yung washing machine pero yung timer ang magkakaproblema at yung mga delay functions.

    @phoenix

    Anong model nabili mo? Papost ng pics para ganun na rin ipabili ko sa Pinas.. Hirap na kasi ang parents ko dun sa twin tub washing machine namin sa bahay.
  • Good Pm, Meron po ako monitor. Nasira ung power cable adaptor nya na may nakalagay na 12v 2ampere. Okay lang b kung bumili din ako ng ibang power cable adaptor n may 12v 2-5ampere?
  • @emmanalcaraz
    As long as the connector and polarity are correct, I don't see any problem.
  • question po.. may mga 12v dc fans na pwede iconvert para maisaksak ko sa 220v ac. Do i need a transformer to it? or kahit mga capacitor lang? Balak ko kasi bumili sa Raon then gagawin ko siyang exhaust para sa box. Mga 4 na fan siguro ang gagawin ko . TIA.
  • guys, any idea kung san pwede makabili ng backlight inverter ng lcd tv? sabi nung tech need daw palitan ung panel (no picture but with sound), then googled at backlight ang problem. since kapag ginamitan ko ng flashlight meron naman picture

    oks, silipin ko. salamat
  • question po.. may mga 12v dc fans na pwede iconvert para maisaksak ko sa 220v ac

    AC-DC adapter 12v output lang ang katapat nyan, hanap ka ng at least 1 ampere output kung multiple fans ang gagamitin mo.

    guys, any idea kung san pwede makabili ng backlight inverter ng lcd tv? sabi nung tech need daw palitan ung panel (no picture but with sound)

    Paano kung yung backlight mismo ang sira? Kung CCFL ang backlight nyan papalitan mo yung CCFL tube. Kung LED naman, hindi inverter ang kailangan mo. May picture ka ba nung panel, kahit yung model# ng LCD at yung backlight connector?
  • mga paps, tanong ulit.. yung lcd tv ko kasi nagbago ng kulay naging bluish siya. nag-search ako sa net ang sinasabi video panel ang may sira. Ano kaya reason ng pag blue ng kulay niya. BTW, pag pinipindot ko yung menu niya walang pagbabago sa kulay. Bale yung display lang talaga. Thanks.
  • ^ Have you checked if there are color controls in the menus?
