230v 50hz to 120v 60hz
592191
I have used this in London, Australia and Hong Kong to convert 230v 50hz to 120v 60hz. I specifically like this converter because it does not only step-down the voltage but corrects the frequency as well. Still need to experiment to see if this is outputting a true sin wave 60hz.

The fan does make some noise when powered on.

I don't really trust the USBs for charging devices. I will still use the normal wall chargers that come with my devices.

I received the packet safely on time. And My Mixi and Grinder (230 V) working on this converter with out any problem

I bought the t3000 for connecting in spain a washlet bought in japan and it works great, no noisy sound  and converts great the 220 to 110. The delivery lasts only 3 days.

The unit solid and now has clarified its instructions for setup. You must wire the timer motor for 220V. You can use both of the 110V loads out for 220V, or just one for a 110V need.

Hi,

Recently, I got a 88V-5 used from ebay.  It seems to be a 87V-5 just with out True RMS. It works good, I used it to measure 120AC and it seems close enough. I mostly use it for electronics use, and for my vehicles (I'm a gearhead).
Its a worth wile investment, even though it is very expensive (ebay is good source).

This is what advertised. Very good quality. Another good think is, what I bought came with 110v/220v 60Hz/50Hz power adaptor. Please see attached photos what I received. You need min 6 hous to build. It is not very easy to install but also not very difficult.

Bought it because it supported 230V, and works great so far (used in for about 1 month).
After some testing it seems to manage about 26-27 In. Hg when using my 3 Gallon Vacuum Chamber.

Works great, but only rated 120 V. I bought a 240/120 V transformer but that doubled the cost. Great for NA travel

I give 5 star to this charger. It is fast. Does the job if you use it in the USA.However inspite of some misleading information about using overseas this came from Amazon with a wall plug adapter that can only be used in the USA.On the manufacturer's web site a mention is made of DPS-3000e but no other details. The information sheet that came with the model I got mentions specification for AC adapter "AC 120V/AC239V/AC220V, 50-60Hz".HOWEVER the adapter I got can only be used with 120V AC 60HZ.So I am disappointed because I had been led to beleive this item will work abroad. SO be warned if you are planning to use it abroad at AC 220V 50Hz better look for another unit.

A great way to power a 20v DC computer directly from 12v DC. No need to inverter to AC and then power supply back to DC.

I don't know how Amazon comes up with 8000 watts, let's do the math.

AC output 120V @ 47AMPS = 6016
AC output 240V @ 23AMPS = 5520

What combination yields 8000 watts?  How come other sites have this listed as a 6000 watt generator, which is a lot more realistic!

If you buy the 220 model understand beforehand that this baby runs on a 220 volt/50hz cycle power system -- to run this sweetheart in North America it means you will need a heavy duty 110/220 step up transformer that can handle the 1200 watts of power the dryer sucks up -- and you will need a Euro to USA grounded plug adapter and 16 awg heavy duty extension cord --factor in shelling out another 150 clams to make this blower blow....

People who are outside of US keep in mind that the podcast studio is 120 volts! Mine is broken because I forgot that (((

Js 572el is awesome ! Square cut and strong with 7,5 ampere. Thank to Amazon

Only needed a small converter to run a birthday present that came as 220 . 100 watts was more than enough. Works great .

This is an excellent product, exactly what I wanted. The problem is that in my country (Peru), the voltage is 220 v / 60 Hz, and the most popular power analyzers are designed to work on 110 Volts only. I have to say, Watts-up is also marketed as a 110 volts input power analyzer too, but luckily, somebody (don't remember the name, but thanks) pointed out that this works on 220 volts, too. And it really does.

At this moment, I've already taken the decision to change an old refrigerator that is eating around 25% more power than a bigger / newer one that we have. I've calculated that it will pay itself, on power savings only, in about 3.5 years, which sounds good to me.

An observation: at the very beginning, and for some reason I still don't know, it showed me very inaccurate information on everything: volts (around 40 v), amps (50 Amps !) and watts (~2000 watts for a very little appliance), resulting in impossible cost rates. It happened to me two or three times, but now it is working very well (for the last 20 days at least). I didn't do anything to correct it, by the way.

I replaced a single 240v outlet with this 120/240 volt combo outlet. This works out great for versatility. Very nice being able to plug either a 240v or 120v tool or both at the same time. If you have a single 240v outlet and have the neutral (white wire) also terminated (wired to but not connected) in the outlet box, it's an easy task.
