This transformer is capable of both up/down voltage conversions for Japan/USA. It Can be used in both 100 and 120 volt countries. This transformer will convert from 120 volt to 100 volt AND from 100 volt to 120 volts - Input: 100/120V and Output: 100/120V. This transformer is rated for 500 Watts max including power surge. This is a heavy duty for continuous use. There is a built in Power ON/OFF Switch and Fuse Protection.TRANSFORMER PURCHASE GUIDE: Remember to leave at least a 100% slack for the transformer, Heating appliances, laser printers and power tools spike when you turn them on. For these products you need to buy a transformer that is at least 3 times the items capacity. ## Features - This continuous use transformer is capable of both up and down voltage conversions for Japan and USA electricity to enable use of Japanese products in USA and USA products in Japan - 500 Watts is the maximum capacity of this transformer including the power surge - It converts 110/120 volt USA power to 100 volt Japan power AND 100 volt to 110/120 volts (means it will convert the American power to Japanese power and also convert Japanese power to American) - Power ON/OFF Switch. Fuse protection for safety - Remember to leave at least a 100% margin for power surges/spike when buying a transformer. For power tools, laser printers and heating appliances like Rice cookers, coffee makers, toasters, halogen or fluorescent bulbs you must leave a power spike margin of 4 times. Please Note: Kindly refer the User Manual before use. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000PC4JL4 | | Best Sellers Rank | #134,411 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #531 in Power Converters | | Brand Name | VCT | | Customer Reviews | 4.6 4.6 out of 5 stars (551) | | Global Trade Identification Number | 00894076000862 | | Item Dimensions D x W x H | 5.75"D x 3.6"W x 3.4"H | | Item Weight | 4.9 pounds | | Manufacturer | VCT Electronics | | Minimum Frequency | 50 hertz | | Model | VT-500J | | Mounting Type | Rack Mount | | Number of Items | 1 | | Part Number | VT-500J | | Power Source | Corded Electric | | Specification Met | UL | | UPC | 894076000862 | ## Product Details - **Brand:** VCT - **Mounting Type:** Rack Mount - **Power Source:** Corded Electric - **Product Dimensions:** 5.75"D x 3.6"W x 3.4"H - **Specification Met:** UL ## Images ![VT-500J - Japanese Step Up/Down Voltage Transformer Converts Japan 100 Volts To 110V OR Vice Versa - 500 Watt - Image 1](https://m.media-amazon.com/images/I/71Qda9flDAL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: wich watt should i pick for stax energizer from japan?** A: Power consumption is listed in the specifications. Go to Stax's official website (stax DOT co DOT jp) and click on "イヤースピーカーのスタックスへようこそ" (which means, "Welcome to STAX Earspeaker". The link should be above another link that says, "Overseas Distributor"). Then, on the next page, click on the tab that says, "製品情報" (which means, "product information".). Click on your product and then Ctrl+F (or equivalent, to search on the page for specified text) for "消費電力" (which means, "power consumption"). Units should be in watts. Should your energizer no longer be in production, scroll down to the bottom of the page and find it in the list of discontinued products and follow the above steps to find the power consumption. If you get a pdf of an image (and you cannot Ctrl+F or equivalent), then use your favorite internet search engine to search for "stax pdf", without quotes, to find the product manual. There should be text in the pdf you can use Ctrl+F or equivalent on. For example, the official product page for the SRM-353X energizer lists its power consumption as 30W. And the new flagship SRM-T8000 hybrid energizer that just came out is specified as consuming up to 95W. If we naively assume that the newest flagship tube energizer from STAX is the most power-hungry model, then take 95W, multiply it by 4, round UP to the nearest transformer model, and call it done. Using this logic, the 500W model should be fine. Another very important thing to note is that in the official product manuals, it is very likely stated that the energizer is rated to ONLY accept an input of 90~100VAC at 50/60Hz. If you are in the USA and have outlets at 120VAC, then this product will not bring the voltage down far enough into the 90~100VAC range. My outlets are measured with a DMM to be at 123VAC, so this product (rated to bring 115VAC down to 100VAC) will only bring the voltage down to 108VAC, which does not fall into the range of 90~100VAC. This is systematic error that will most likely damage your energizer over time. Follow the product specs to the letter. Don't take risks on an expensive, sensitive ~$1000 amplifier. **Q: I have a vacuum cleaner that i brought from japan and it says 100v, 1000w,, 50-60hz. will this converter make this vacuum cleaner work in us?** A: You cannot use a 1000 Watt vacuum cleaner with a 500 watt transformer. You should be buying atleast a 2000 watt transformer.http://www.amazon.com/VCT-VT-2000J-Japanese-Transformer-Converts/dp/B004O9WIK8/ref=sr_1_1?s=hi&ie=UTF8&qid=1436467556&sr=1-1&keywords=vct+vt-2000j **Q: Would this transformer work well with japanese dryer (ac100v 50-60hz 1200w)?** A: The transformer is rated at 2000 watts. Your dryer is rated at 1200 watts. It should work with plenty of capacity to spare , however I'd keep an eye on it to ensure it does not overheat, just because devices like heating units and large motors tend to load up devices like this. **Q: I blew the fuse on my VT-1000J. Would someone please kindly let me know either a replacement fuse model number or specs? Thanks so much!** A: "F10AL250V" seem to be fast acting according to specs. Would slow-blow be better for this application? ## Frequently Bought Together - VCT VT-500J - Japanese Step Up/Down Voltage Transformer Converts Japan 100 Volts To 110V OR Vice Versa - 500 Watt - Metro (METRO) kotatsu Replacement heater U-shaped quartz tube MSU-501H (K) - Alamic Corner Brace 30 x 30mm Stainless Steel Black Brace Corner Steel Joint Right Angle Bracket Fastener with Screws - 12 Pcs --- ## 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.sn/products/1592196-vt-500j-japanese-step-up-down-voltage-transformer-converts-japan](https://www.desertcart.sn/products/1592196-vt-500j-japanese-step-up-down-voltage-transformer-converts-japan) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-26*
