I have been looking for a step up transformer to use a 140W appliance from China in the US. Ideally it wouldn't be one of the big bulky ones!

The closest thing I have found so far is this transformer, but I would need an adapter at both ends (I think) to be able to plug it into a US outlet and to be able to plug my US appliance into it.

Does anyone know of a more suitable transformer, ideally that wouldn't require additional adapters?

  • What does "good" mean for you? Unfortunately this is a subjective term and therefore we can't really answer this. – JoErNanO May 12 '17 at 14:22
  • By "Good" I mean one that doesn't require additional adapters to work mostly, but also will work OK for a 140 Watt appliance. – Ben Holness May 12 '17 at 15:52
  • I have changed "Good" to "Suitable" – Ben Holness May 12 '17 at 16:02

    @BenHolness The StackExchange Q&A is best suited for questions that have a single, definitive answer; it doesn't work well for suggestions or reviews, which seem to be what you are asking for. Please take the site [tour] and review the [help] and see if the question can be phrased so it doesn't ask for suggestions or lists. – choster May 12 '17 at 16:12

  • Beware that the device you linked is not a true transformer but rather an electronic voltage converter. Much lighter and cheaper but the output is not as clean. Some devices will not like that. – Loren Pechtel May 13 '17 at 00:20

https://www.amazon.com/dp/B0022QOSDK?psc=1 or similar is probably okay. enter image description here

I have a couple similar ones and a Chinese power bar. If you can find them locally you can save on shipping (a proper transformer will not be light!).

I appreciate your desire to have something small and light, but keep in mind that virtually none of these devices are UL or CSA approved (CE means nothing) and I feel much safer with something inside a GROUNDED METAL BOX, so even if it fails the worst you will likely get is some lungs full of toxic smoke, and not a fire or a fatal electric shock.

The shown receptacles accept both the parallel blade Chinese style and the angled variety, as well as the 2-pin Euro style. Not that securely, but they fit in.

I would also take the ratings with a bit of a grain of salt, and stay well below the maximum rating.
