Can I plug a power strip with other outlets into a voltage converter in India?

Also the frequency in India (50 Hz) differs from the frequency in the United States of America (60 Hz). You should use a voltage converter which also changes the frequency, but these are hard to find. If your converter cannot change the frequency, be warned! Be especially careful with moving, rotating and time related appliances like clocks, shavers and electric fan heaters.

To be sure, check the label on the appliance. Some appliances never need a converter. If the label states 'INPUT: 100-240V, 50/60 Hz' the appliance can be used in all countries in the world. This is common for chargers of tablets/laptops, photo cameras, cell phones, toothbrushes, etc.

This is just one source that came up. Many of your things may need only a plug adapter

You didn't show the voltage converter you plan to use, but it is undoubtedly unsuitable for your purpose.

This was the first voltage converter that I found on Amazon. Note that it says it is not compatible with a hair dryer or hair straightener.

The next one I found has grounded receptacles that are "phony" because it uses an non-grounding, 2 pin europlug.

No appliance with a polarizing US plug (one blade wider) should ever be used with an non-grounding plug.

Almost all laptop and camera chargers today use a USB voltage converter which is multivoltage (Input: 100-240 VAC) and should not need an additional voltage converter. Most US hair dryers and straighteners need polarized power, which the converters I found do not provide. Don't use devices from of the US; get them over there.

You must be extremely careful to make ABSOLUTELY CERTAIN that the voltage converter will handle the wattage requirement of a hire dryer or straightener. Most of these appliances required 1200 to maybe as high as 2000 watts or more. Generally the inexpensive converter will ONLY handle up to 50 watts. You can buy a high wattage converter but it tends to be expensive and heavy. If those appliances are critical to your well being, it would be smarter to buy dual voltage appliances.

AND -- you most likely do not need a converter for your camera and laptop. However, to be certain double check the voltage input required printed on the plug.

You have repeatedly asked this question before but have deleted your question. Did you not like the answers?

Voltage converters used to be transformers for around 1800W and were very heavy. Newer ones were light because they used transistors to "chop" the top off of the wave form to produce half the voltage, but that waveform could damage electronic, so newer ones switch between a small transformer for up to 50W for electronics and a transistorized converter for non-electronics.

But the caveat remains the same. They should not be used with US appliances that have grounding (third round pin) plugs or polarized (one blade wider) plugs if they plug into European power with a non-grounding, two round pin plug and don't have any other provision for grounding.

I plan to use this voltage converter and this power surge protector. I have yet to purchase them. In response to the question about deleting my previous questions, I'm not sure what happened. I tried to post the questions, and then the link to the question was broken, so I couldn't see the answers. For some reason it worked this time.

Also, the straightener I plan to take with me is the one I purchased in Spain that has the two round prongs. The print on it says 220V-240V. As far as a hair dryer goes, it looks like it might be best to not take one and to maybe purchase one there if I really need it.

keila,

Before buying anything, I'd suggest checking the "Input Voltage" specifications on each of the products you'll be travelling with as you may not need a voltage converter. Many products these days are designed for "world" operation from 100-240 VAC, so a converter is not required for those.

The Voltage Adapter that you linked has a switch to choose between Converter and Adapter modes. It would be easy to forget the switch and use the wrong mode for a product which is designed for "world operation". That's a concern because both the converter and the chargers use switch-mode power supplies. There are various designs for these power supplies, and some design combinations of these don't work well together causing one of them to self destruct.

I wouldn't recommend using the Power Bar / Surge Protector that you linked. You can either buy a Power Bar designed for 220 V. or if you're charging a lot of USB devices, use a USB Travel Charger (there are many of these available).

Regarding each of the items you mentioned.....

• Laptop - most Laptop chargers these days are designed for operation from 100-240 VAC, so a voltage converter isn't needed.
• Camera - ditto
• Hair Dryer - your hotel may provide hair dryers with the room. If not it would be easy to buy a 220 VAC model when you arrive in India. The resistive heating element of the hair dryer won't be affected by a "rough" AC waveform but the motor won't work as well on 50 Hz. If it has any electronic controls, that could also be a problem when used with a Voltage Converter.
• Hair Straightener - you stated that this is a 220 VAC model, so you'll only need a Plug Adapter to use that.
• Cell phone - are you taking a phone? If so, this is likely the same scenario as a Laptop.

I'd suggest packing along at least a couple of Plug Adapters as these are easy to misplace, including at least one grounded model.

Finally you may find that the quality of the AC power there is not the same that you're used to in North America. Depending on where you're travelling in India, you may experience brownouts surges / spikes or outages at times. For those that are interested in the technical details, this report provides some good information.

It is amazing that with a little additional information our answers can be more precise. Your Spanish purchased 240v straightener will be fine. Just get a plug adapter that will fit in an India outlet. Buying a 240v hair dryer is a terrific idea. Then you will not need a converter for anything.

But more caution --- do not use a power strip with surge protection. It doesn't match up well with 240v. Get a cheap one without any surge protection. You don't need surge protection for anything. OR buy a power strip when you get there.

Every notice how extension cords with only a two blade plug end have a receptacle end with a protrution to prevent plugging in a grounding plug? That's because essential safety features that are provided by the grounding pin would be defeated if plugged into the ungrounded extension cord. It's probably by law, but at least the only way to get UL listing on the extension cord.

Well, the voltage converter you linked to similarly has a receptacle to accept a US grounding plug but no provision for grounding on the plug end or elsewhere. The safety provided to an appliance by a grounding plug or a polarizing plug would be defeated. I'm appalled that it is even sold by Amazon. Don't buy it.
