PadPrikKhing Posted January 19, 2023 Share Posted January 19, 2023 I've been searching for hours on Lazada and Shopee, and it's just frustrating. Many of the ones there are overpriced and/or will take too long to deliver because they're coming from China or whatever. Are there stores in town that sell these of decent quality? I need one that handles 500W of the more heavy duty type that has a metal box construction, and a smaller one that handles only 100W... that one could be one of the little plastic ones, as the use case will be occasional, for a mere 40W device, and I will never leave it running unattended (actually I won't leave any of them, of any wattage, unattended). I also don't want to hoof it all over town looking at places that might or might not carry these (hence my appeal here for personal experience/recommendations). I'm living in in San Sai now, without a car or motorbike, so when I need to make forays into town to get things, I need specific info or I burn a lot of money running around. Thanks in advance.

flare Posted January 19, 2023 Share Posted January 19, 2023 If you can't source one locally, if 750 baht for a model capable of handling 500w is a decent price, there's one on Lazada from a shop in Samui Prakan with a delivery estimate to Chiang Mai of Jan 22nd-25th (if ordered today): https://s.lazada.co.th/s.iwXax Link to comment Share on other sites More sharing options...
bluejets Posted January 19, 2023 Share Posted January 19, 2023 First obvious question would be , what do you intend to use it for, as there may well be ( and usually are these days) an alternative approach. Link to comment Share on other sites More sharing options...

hkt83100 Posted January 20, 2023 Share Posted January 20, 2023 And don't forget: Some appliances depend on the correct frequency. A transformer will take care of the voltage, but 50/60 Hz may still be an issue. Link to comment Share on other sites More sharing options...
Popular Post The Old Bull Posted January 20, 2023 Popular Post Share Posted January 20, 2023 Good luck, unless it's hard wired . Some Thai will come along when you are not watching and plug your 110V device into the 220V and that will be the end of that. Been there done it. 1 3 Link to comment Share on other sites More sharing options...
MrBrad Posted January 20, 2023 Share Posted January 20, 2023 There's a shop on the south side of Chang Moi Road that sell transformers of all sizes. Looking at the streetview, I'm not sure that I've captured the right store, but it's near the one on the link. I'd bought a transformer there years ago; I think this is the place.https://goo.gl/maps/cYBgPCRDPD2bA5f27 Link to comment Share on other sites More sharing options...
VirgoSG Posted January 20, 2023 Share Posted January 20, 2023 I've used RS Components in Thailand and Singapore quite a few times. Very professional, product range is amazing, and delivery fast. Take a look there. They have quite a range of step-down transformershttps://th.rs-online.com/web/ Link to comment Share on other sites More sharing options...
Satcommlee Posted January 20, 2023 Share Posted January 20, 2023 Amorn has these, google your local "Amorn" electronics store. Link to comment Share on other sites More sharing options...

Take note: the Amorn shown as being in with Tesco Lotus at Ruam Choke / Mee Choke no longer exists, even though it's still listed on their website. One would best go to their location on the north side of the moat. Link to comment Share on other sites More sharing options...

Won't happen, as I live alone and no one will be plugging things in except me. I will also be securing things so that even I can't make that error.

TimeMachine Posted January 20, 2023 Share Posted January 20, 2023 SOME 110v devices can be opened and the circuit can be modified simply to be 240v. Basically the circuit for 110v uses a voltage doubler design and by switching back to normal bridge rectifier brings it back to 240v compatible. Should be some YouTube vids on the matter.

I'm just looking to run my Sony stereo receiver. I think I need something very much like the one in the photo I posted...? Link to comment Share on other sites More sharing options...

I want to use a 500W one to run a Sony stereo receiver that I shipped over here (I know, I know...) that draws 220W max power. I don't want to use a 300W transformer with it, as that's not enough margin for my taste. Also, 500W models are only a couple of hundred baht more than 300W models. So that one would only be in use when I watch TV or a movie and run sound through it. The smaller one I am going to use to just run a small 40W dry herb vaporizer, and it, again, will always be "supervised" when on. Link to comment Share on other sites More sharing options...
Peterphuket Posted January 20, 2023 Share Posted January 20, 2023 I just ordered a variac from 500W at Lazada for 1000 thb, you can make choice for every voltage you like until 250V Link to comment Share on other sites More sharing options...

I used to have an older Sony surround receiver with a little switch inside the case for 110/220v. Although I never had any need for it, it was easily accessible after unscrewing the metal case. You might google your model and see if it also has this switch. This is a way simpler solution than buying and hooking up a bulky transformer.

Dellboy218 Posted January 21, 2023 Share Posted January 21, 2023 I've got a 300W one you can take away. Link to comment Share on other sites More sharing options...
elektrified Posted January 22, 2023 Share Posted January 22, 2023 I own 4 of them. My favorites are the two that were custom built for me by Siam Neonline. They will build any configuration you want and ship it to you from Bangkok within about 4 days. I have a 2000 and a 3000 watts. Very well built, https://siamneonline.com/en/Step-Down Link to comment Share on other sites More sharing options...
