標題: 點可以安全地係香港用110V電器 [打印本頁]

作者: Hkwan 時間: 2008-11-22 12:34 AM 標題: 點可以安全地係香港用110V電器

大家好,我係US住架,岩岩上網買左個按摩枕頭比我香港的女友,以為係用乾電,點知買左番黎先知係要用濕電, 但佢又無寫electric input/output 果D,就係話plug into 120V power AC outlet. 咁我想問係香港用係咪會危險,買個220v to 110v變壓器有無用?點先可以用得安全呢? 個枕頭唔係好大,我諗Watt數唔高..但我唔肯定
我無呢方面既知識.. 可唔可以幫我?

ps.唔知有無貼錯版

yes, 非常危險.
110v to 220v有用

tell your gf go to 旺角新填地街買個 110v to 220v 的變壓器便可以.
將個枕頭既插頭 plug 入個 transformer, 但us 插頭有 d 唔同,
你要換埋枕頭個插頭.

你諗watt數唔高

真係好危險呀你, 睇吓說明書用幾多watt, 再買隻watt數比佢大既火牛喇

我試過風筒連火牛一齊燒晒

用電量較大/長使用時間既電器跟本唔適宜強行變壓

樓主自己考慮清楚,安全至上呀

唔該晒...

咁如果用

我就係check左說明書無寫..我send 左email去間公司customer service去問....

先決條件是check清楚個按摩枕頭的所需Watts,才配對買變壓器;
否則可以做正變壓器過熱,引起火警

風筒你都走去用變壓器

普遍更弱既風筒都有 800W 喇

電量大既電器唔係唔用得變壓器, 只不過係一個高watt數既變壓器係好貴同size好大, 一般人唔會用

surge protection 同 transformer 係兩樣野, 係冇關係既

surge protection只係用嚟保護, 當其他電器開關時有機會放出高壓電池波,
又或者行雷時高壓走入屋, 而損壞電器

絕對同意～

以前未有plasma電視，好多香港人都用日本110v顯像管電視，
或者用電量相對較細o既日版遊戲機（PS2 etc），都好多人選擇用變壓器（火牛／transformer）o拉

，
只要用較安全o既火牛，
基本上我又唔覺有太大問題～
（但當然，多一隻用電電器，自然多一層風險）

但高Watts數果Ｄ牛都幾貴（閒閒地要成千蚊），而且又成個鞋盒咁大，通風又要做得好（否則散唔到熱），啱唔啱用，真係要諗過

Thanks for every brothers for commenting
i just got the information from the company

the massage pillow - 120V, 200mA, 25W

This is a small W device,right?

咁好細啫
買個大約 500mA, 50W 既transformer 喇

雖然而家應該絕大部份既電器都係 50/60Hz
不過你都留意吓你個massage pillow係唔係 50/60Hz 喇
否則美國好似係用 60Hz, 唔啱香港 50Hz 用

作者: Hkwan 時間: 2008-11-26 07:08 AM

唔該晒~!!我又問下間公司先~~~~

作者: Hkwan 時間: 2008-12-4 01:39 PM

真係60Hz 喎...點算

咁係咪會用唔到?

我相信基本上冇乜問題既, 如果係用switching mode power supply的話,

不過都唔知佢既設計係咩

你不如直接問佢用50Hz既power source 有冇問題喇

應該買220v轉110v,因為香港220v電源要將佢減壓到110v.

thats right man
don't mess it up
also, as another person suggested, u should buy an Adapter (or Transfomer, whatever it calls) more mA, etc. than your device requires
the guy who burned his hair dryer and adapter altogether might due to that, another cause might be the quality of the adapter
if i were u, if u r really concern about the safety for your gf, this is y u ask here, so u shouldn't go bid an adapter from ebay la
go to a store to buy one and pay a bit more for a better one for security, u shouldn't try to save that $50-100 to risk your gf's life man
another thing is, its good that u ask in here as well, because most of the salespersons suck
they just tell u whatever they r not sure of, they just answer u what they think only, because people don't take responsibility for what they say as they won't care of the consequence, u fail, its ya own business, the reason is simple, treat the info. u get as reference, thats the right attitude, its simple, because the salesperson are hired to increase the odd of making successful sales, they do not require related knowledge for the recruitment, and they are unprofessional not to learn more in order to give relevant info. for their customers
go to those local electrical stores and buy the adapter and ask for the store people for their opinion, as some of them are elect. engineers
they know how to calculate the power u need for ya device since they are the expert of that field, remember to tell them all the info. e.g. mA
for the difference of the plug & the use of the transformer, u don't need to worry too much about it, as the danger they r always mentioning is the potential danger, for any devices, or even anything in the world, there must be potential danger
the main reason the danger that the 2-leg plug would cause is because it doesn't stand securely compares to the 3-leg one since it's easily being dislocated, well, that's the risk u have to bear
and the salespersons keep overemphasizing the danger of 2-leg is most likely they wanna do more business as u have to buy the 3-leg adapter
anyways, those are just my opinion from my experience, u should treat it as a reference
finally, again, as an official tone, it's recommended not to use the device not suitable for use in HK, haha...

how much is the converter
