What is Reddit's opinion of ROCKSTONE POWER 3000 Watt Voltage Converter Transformer - Heavy Duty Step Up/Down AC 110V/120V/220V/240V Power Converter - Circuit Breaker Protection – DC 5V USB Port - CE Certified [3-Year Warranty]?

From 3.5 billion Reddit comments

I lived in Europe for a few years and powered my whole studio of 110v gear with one of these. Worked fine, no issues at all, even with my big power amp.

You might be able to add in a subpanel, which would be way cheaper than a full replacement of your old panel. Failing that, you could also replace some of your breakers with tandem breakers to open up some more room in your current panel.

A less qualified electrician would tell you to just tap into the stove’s circuit, but it certainly does violate code.

Now, the easier way would be to just buy a sturdy voltage converter front the hardware store. They plug into 120V outlets and step it up to a 240V output. Something like this. Would save you a tidy $1700. I would recommend buying in store instead of rolling the dice with online stock for this buy.

Still in the planning stages, but...

• 32 core Threadripper Pro
• 2 3090 Ti GPUs (probably replacing them, or waiting, for 4090 Ti)
• 512 Gigs RAM
• Asus WRX80E

The main issue is that the power requirements for the GPU's are going up so much. 2 3090 Ti's will consume 900 watts on average, and the rumor is that 2 4090 Ti's will consume 1200 watts. Then add in everything else (fans, drives, other peripherals).

There may be workarounds, such as using a step-up converter like this one:

Should work on a 20 amp 120V outlet.

There's always getting a 220V outlet installed as well.

I was thinking about this one. Looks like I will probs have to get a 3000 watt transformer for a 1600W continuous load of an S15.

The problem is getting the 220 in a single phase as you would in Europe. Here in the states you will get 240V as two 120V phases.

The best bet from Amazon (that I found in a quick search) is this: https://www.amazon.com/dp/B00CLYMMCC

Unfortunately, I don't know of anyone locally who would sell something like that.

you can buy a transformer and use the 220V kettle.

4 years later and your help is still appreciated! Thanks :)

I dont know for sure without know what you have exactly, but it seems like you got a power converter/transformer. https://www.amazon.com/Rockstone-3000-Watt-Transformer-Converter/dp/B00CLYMMCC?ref_=Oct_s9_apbd_otopr_hd_bw_bk1DN&pf_rd_r=2P547J029V277SBNK7WT&pf_rd_p=82eeb098-d16f-57fb-90ec-6c7f4a317a02&pf_rd_s=merchandised-search-10&pf_rd_t=BROWSE&pf_rd_i=10967761

I'm going to assume you are in Korea and brought US products/appliances with you (110v).

Your converter should have a Korean plug attached (or input) and a slot for the US plug (or output). Korea provides 220v power and will blow up your appliances if you dont have something to feed the power through.

You plug the converter box into the wall with the Korean plug, so juice is flowing in. Then plug your appliances into the box and it should safely output power to your US devices. I usually run a power strip off it for to use multiple devices. You do need to make sure you have the settings correct on the converter box though, so someone might need to help you read it anyways.

If you look on your other electronic devices, for example your phone charger plug, you can see a specification on the side of the plug with something like 110-240v. This means that plug is safe to take voltage within this range. But US appliances like hairdryers, humidifiers, kitchen appliances (things with motors), that don't have this specification, mean its typically 110v max and can short circuit/burn/go boom your appliances by forcing 220v through it.

Want it on the Cheap? this will work:

Step up / step down transformers are easy to find. For example.

Why do you want a center tap? Just connect the 120V gear to the generator directly.
