It is smaller than I expected it to be, which is great, and is very heavy. Looks like it’s made from quality aluminum cover and it feels very sturdy. It worked as expected (I’m using it for a turntable) and is super quiet (no 60hz hum). Came with simple and clear instructions in proper English. Review: Does Exactly What It's Supposed To Do - Purchased this to run Japanese voltage electronics. Works perfectly. Build quality is excellent. I leave the switch on the back on all the time and the unit does not generate excess heat. The only thing is that I did not get the extra fuses pictured on the purchase page - they could be inside the unit. Would purchase again. ## Features - 300 WATT STEP UP / DOWN JAPANESE VOLTAGE TRANSFORMER - This step up and step down voltage transformer can be used for small electronic appliances.

Also, make sure the wattage rating for the transformer is 3X MORE than that of the appliance. **Q: Hi: is this transformer powerful enough for a japanese cd player.. s300s by yamaha? or do i need more voltage/ wattage? thanks lr** A: Japanese electrical things run at 100 volts, not 120 volts like here in America. This transformer has two different voltages one is 100 volts and the other is 120 volts. So if you want to use a japanese CD player plug it in the 100 outlet. If you go to Japan and want to use a US CD player you would plug it in the 120 outlet providing you switch the voltage in the back. Leave it at 120 volts. You do not need anything else with this transformer. **Q: I have some small Japanese kitchen appliances like coffee maker and small takoyaki maker .Will i be able to use my appliances in the US?** A: No, the VC100J provides up to 100 watts and your appliances will have a much higher wattage consumption. The VC2000J is commonly recommended for cooking and heating appliances. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Smaller than expected *by G***N on May 6, 2024* VC-300J - This is the 300w unit. It is smaller than I expected it to be, which is great, and is very heavy. Looks like it’s made from quality aluminum cover and it feels very sturdy. It worked as expected (I’m using it for a turntable) and is super quiet (no 60hz hum). Came with simple and clear instructions in proper English. ### ⭐⭐⭐⭐⭐ Does Exactly What It's Supposed To Do *by T***H on September 13, 2023* Purchased this to run Japanese voltage electronics. Works perfectly. Build quality is excellent. I leave the switch on the back on all the time and the unit does not generate excess heat. The only thing is that I did not get the extra fuses pictured on the purchase page - they could be inside the unit. Would purchase again. ### ⭐⭐⭐⭐ Does the job, but universal outlets not great *by M***W on March 25, 2021* Haven't had it long enough to evaluate quality as a whole, but it is doing the job I needed: powering a stereo imported from Japan that requires 100V. The only complaint so far is the "universal outlets" - they are not easy to get a 2-prong plug into. The vertical prongs want to go into the sideways "clamps" that appear designed for the sideways prongs I've seen on some plugs. You have to kind of spread them apart to get the prongs in between them. This may be intentional to put adequate pressure on the plug, but it makes it a bit of a hassle to plug something in. ## Frequently Bought Together - PowerBright 300 Watts Japanese Voltage Transformers, Step Up and Down Japan Converter, can be Used in 120 Volt and 100V Countries, Convert from 120V to 100V and 100V to 120V, Universal Outlet Socket - AZUMAYA Kotatsu Heater Folding Legs Table W36.0 x D20.0 x H14.5 Inches Natural Oak and Rubber Wood Material Home and Living Natural Oak Wooden Color ELFI-901OAK - 120V to 100V Voltage Converter 500watts Step Down toroidal Voltage Converter for Japan appliances Used in US［CE, CQC Certified］ --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/101143511-300-watts-japanese-voltage-transformers-step-up-and-down-japan](https://www.desertcart.sk/products/101143511-300-watts-japanese-voltage-transformers-step-up-and-down-japan) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-22*
