It features two adjustable voltage outputs (6-15V) for vintage tone emulation, multiple current ratings to support diverse pedal types, and includes 3 patch cables. Designed for professional pedalboards, it ensures reliable, quiet power for analog and digital pedals alike, making it a trusted choice for gigging musicians. ## Description The Iso-Brick Power Supply is small and light with tons of quiet, noise-free DC power on tap ready to run a wide range of pedal types without crowding or weighing down your pedalboard. Each of the Iso-Brick Power Supplys 10 outputs is fully isolated, eliminating gig-ending ground loop noise. Whether analog or digital, positive or negative ground, this power box has you covered. The MXR team broke down these 10 outputs to accommodate a variety of voltage and current requirements: two 9V outputs at 100mA, two 9V outputs at 300mA, two 9V outputs at 450mA, two 18V outputs at 250mA, and two variable outputs adjustable from 6V to 15V at 250mA. The two variable outputs can be used to emulate voltage sag, a drained battery effect sought by many vintage tonechasers. On top of all that, the Iso-Brick Power Supply comes in a small, lightweight housing thats built like a tank. Features power on/off and connection status LEDs. Put this little box on your pedalboard to make sure it runs reliably and quietly gig after gig. Review: Really great power supply - I've had this on my board for several years now, and I've reconfigured my board many, many times, and done numerous gigs with it. it is rock solid, and handles my needs perfectly. Review: MXR power - This thing is awesome and sturdy. I use it every day-sometimes powering it on and off a few times, and it never fails. 2 outputs with adjustable voltage make for really cool bias controls on fuzz and OD. This also makes it very easy to fry any pedals requiring 9v or less, as there are 18v outputs here as well. I really like this brick. Thank you. ## Features - Pedalboard-friendly size - 10 fully-isolated outputs - Quiet, noise-free operation - Sturdy Construction - Bundle includes 3 MXR patch cables (6") ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07FXXSF54 | | Amperage | 300 Milliamps | | Best Sellers Rank | #47,382 in Musical Instruments ( See Top 100 in Musical Instruments ) #237 in Guitar & Bass Pedal Boards & Cases | | Brand | MXR | | Color | black | | Connector Type | Barrel Connector | | Connector Type Used on Cable | Barrel Connector | | Customer Reviews | 4.8 out of 5 stars 127 Reviews | | Enclosure Material | Alloy Steel | | Form Factor | box | | Input Voltage | 18 Volts | | Item Weight | 1.05 Kilograms | | Manufacturer | Dunlop | | Material | Alloy Steel | | Model Number | M238 | | Output Current | 300 Milliamps | | Output Voltage | 9 Volts (DC) | | Output Wattage | 31.8 Watts | | UPC | 811054031700 | ## Product Details - **Brand:** MXR - **Color:** black - **Item Weight:** 1.05 Kilograms - **Connector Type:** Barrel Connector - **Input Voltage:** 18 Volts ## Images ![MXR M238 Iso-Brick Power Supply with 3 Patch Cables - Image 1](https://m.media-amazon.com/images/I/71fe1PfPdFL.jpg) ![MXR M238 Iso-Brick Power Supply with 3 Patch Cables - Image 2](https://m.media-amazon.com/images/I/71ZsBq63f8L.jpg) ![MXR M238 Iso-Brick Power Supply with 3 Patch Cables - Image 3](https://m.media-amazon.com/images/I/71np3cWTy+L.jpg) ![MXR M238 Iso-Brick Power Supply with 3 Patch Cables - Image 4](https://m.media-amazon.com/images/I/51BSBDQNlZL.jpg) ![MXR M238 Iso-Brick Power Supply with 3 Patch Cables - Image 5](https://m.media-amazon.com/images/I/41XFZmNLRjL.jpg) ## Questions & Answers **Q: Does the adapter do both 110 and 220v?** A: No. It does not. **Q: Will this fit underneath a Temple Audio Duo 24?** A: Yes it will. **Q: Can i power one iso brick with another? basically link 2 together?** A: No. Either run both separately or get a different power supply that has more ports. **Q: Are the power cables to the pedals included?** A: Yes they are. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Really great power supply *by J***N on October 23, 2025* I've had this on my board for several years now, and I've reconfigured my board many, many times, and done numerous gigs with it. it is rock solid, and handles my needs perfectly. ### ⭐⭐⭐⭐⭐ MXR power *by B***Y on September 27, 2023* This thing is awesome and sturdy. I use it every day-sometimes powering it on and off a few times, and it never fails. 2 outputs with adjustable voltage make for really cool bias controls on fuzz and OD.

Thank you. ### ⭐⭐⭐⭐⭐ Compact, sturdy, does its job! *by B***N on March 13, 2021* Great power supply so far! The one concern I’ve heard with these units are their adapter cords are thin. Not sure if newer ISO-Bricks have a more substantial cord but I’ve got no concerns that it won’t hold up. ## Frequently Bought Together - MXR M238 Iso-Brick Power Supply with 3 Patch Cables - MXR Patch Cable 6 in|15 cm - 3 Pack (3PDCP06) - Boss TU-3W Waza Craft Chromatic Tuner with Bypass --- ## 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.com.om/products/80715490-mxr-m238-iso-brick-power-supply-with-3-patch-cables](https://www.desertcart.com.om/products/80715490-mxr-m238-iso-brick-power-supply-with-3-patch-cables) --- *Product available on Desertcart Oman* *Store origin: OM* *Last updated: 2026-07-05*
