Reddit reviews PowerBright Step Up & Down Transformer, Power ON/Off Switch, Can be Used in 110 Volt Countries and 220 Volt Countries, Convert from 220-240 Volt to 110-120 Volt AND from 110-120 Volt to 220-240 (500W)

You cannot just wire it into a 120v outlet. If you have an electric clothes dryer, that will use 240. Or an electric range. Still I wouldn't recommend you mess around with this - get help from someone who knows what they're doing. Or as someone else recommended, get a 120-240 transformer. Something like this.

I'm betting you can find one cheaper locally though.

I got this one: https://smile.amazon.com/dp/B000MX1QXA/ref=cm_sw_r_cp_apa_i_n64WDb30J7A68

The mains output voltage in residential homes in Kenya is 240V, compared to 120V in the US and Japan. Your American 3DS charger is only rated up to 120V. As soon as you plugged it into the Kenyan power outlet, your 3DS power adapter fried. You will need to buy a brand new one when you return to the US, or you can get one in Kenya depending on how long you'll actually be there.

Your laptop's/iPod's/phone's power adapters did not fry because adapters for these devices are usually rated for the range 110V-240V. It is only really Nintendo's adapters that I have to watch out for nowadays.

Next time, do not use those small outlet converters for devices that are not rated at the proper mains voltage. What you need is a transformer, and you should not cheap out on this because transformers can be risky to use.

If the device says "INPUT 100-240v" (or 110-220v, etc...) on it you will only need a plug adapter.

If not, you will need a step-down voltage converter. These things are bulky and heavy and you may find it easier just to buy a new whatever over here. They have cheaper, smaller ones but I've yet to use or even read reviews of one that seems dependable. They tend to break.

Must be one of those cheap solid state transformers, apparently all the cheap travel converters on Amazon have this limitation. You might have to get a full size transformer and not a travel sized one. Something like this

Before you buy a transformer, check on the bottom of the fan or on its power adapter (if it has one) if it's rated for full-range (100-240V) use. I don't see any information in the manual for this model, but reviewers of other DC-powered fans by this manufacturer claim that the DC adapters for those are full-range.

If it's not full range, then see the following:

The manual doesn't list the amperage/wattage for this fan, but it does specify a 2.5-amp fuse for the cord. This means that at 120V, the fan can draw up to 300VA (about 300W) at full power.

With this in mind, I would recommend a 400W step-down transformer or larger. You want to use a converter with an actual transformer in it, like this one. Don't use a step-down converter with a triac (very light-weight and will usually be rated for a very high power for its size).

I would not expect the lower frequency to adversely affect the electronics, since the electronic parts will be fed from a rectifier.

The item you linked to pulls almost 5 amps at 110 volts which is ~500 watts. The transformer you said 'went up in smoke' was rated for 100 watts so I'm sure it didn't last very long at all. You need a simple step down transformer thats rated at >500 watts. This should work: https://www.amazon.com/Bright-VC500W-Voltage-Transformer-converter/dp/B000MX1QXA/ref=sr_1_5?s=hi&ie=UTF8&qid=1542787838&sr=1-5&keywords=500W+transformer although I'm not sure of the type of plugs used in the philipines.

I looked at the manual for your receiver, and it two things make me think it will not work on 240V

• No voltage selector switch on the back
  
  
• Specifically says it has an analog power supply
  
  You will need a step down transformer like this
  

Many thanks

Looking at the part lists, I think it is not worth it to source and swap all the individual components!

I may consider the step-down converter indeed. Any particular model/brand to recommend?
There are many variants of this on Amazon:

Good enough to use the sewing machine a couple of times a week?

All you need is a transformer to step down voltage.

Something like this

So would this work then?

I just bought a DP-300F in Germany, I was looking through the manual and saw that it only takes 120V as input.
Could I get by with just purchasing one of these?
