IOGear provided very little information about compatible power supplies on their website, only that it requires a 12V adapter with a center-positive barrel connector and, by the look of the inner connector of the jack, a 2.5mm hole. However, I found the HDMI version of this model (GSM1942H) has a rated power draw of a little over 3W. To save some search time for someone else: this power supply works great! In fact, it’s overkill for a device that pulls about 3W. For this particular use case, you should not have any issues with heat, noise level, or fit. Time will tell for durability, but the barrel tip fits right into the jack so it’s as easy to install as plug it into the device, plug the IEC cable into the brick, and plug the IEC cable into a power receptacle. Review: This is a great replacement power supply for Sling TV Streaming/OTA TV Box. - The power supply on my Sling TV Streaming / OTA TV Dual Tuner Box went bad and this power supply provided plenty of power to run it after I put it into service. ## Features - Input: AC 100 - 240V, 50 / 60Hz ; Output: DC 12V, Max 3A, 36W ; It can supply with currents less than 3A. ---such as 500mA, 1A, 1.5A, 2A, 3A.

If it draws more than 3 amps at 12 volts, no. In fact, I would suggest limiting it to 2.5 amps. **Q: Specs on directions: outer power 36w, power supply: input voltage ac85-265v, 12 v adapter. will this work? for a light ring for zoom calls. thank you!** A: As long as well under 3.0 amps, yes **Q: Will this work with the irig pro? all specs seem to fit but i’m wondering about the barrel plug...** A: Only you can answer that question. The plug will fit 5.5x2.5mm connector pins. If the device you wish to power has this connector size and the power supply meets all other specs, it should work. The unit also comes with an adapter that allows you to cut the tip off the the old power adapter of the unit you wish to power and connect those wires to the adapter. Basically, if the 5.5x2.5mm barrel is not an exact fit, connect the barrel tip you were using to this adapter. **Q: Would this work for ho elite 2201x??** A: No ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works for an IOGear GSM1942! *by J***N on September 13, 2025* I picked up this power supply for an IOGear KVMR (GSM1942, a dual DisplayPort, 2 PC switch) that I bought used without any of the cables or the power supply.

It is replacing a lost shiatsu massager's power supply. It does not get hot even with all options running so that's a HUGE plus for me. My only "con" for this is the lack of UL certification. It meets RoHS and CE certifications, but RoHS focuses more on what materials use used in the device and CE holds a lower standard than UL for quality and safety. TLDR: Good power supply provided your device uses less than 36 watts. ## Frequently Bought Together - SHNITPWR 12V 3A 36W AC DC Power Supply Adapter 100V~240V AC to DC 12 Volt 3 Amp Converter Transformer LED Driver with 5.5x2.5mm Plug for 5050 3528 LED Strip 3D Printer CCTV Security System LCD Monitor - Facmogu DC 12V 3A Power Adapter, 100-240V AC to DC 12V 3A 36W Power Suppy with Barrel Connector 5.5x2.5mm & 5.5x2.1mm, 12 Volt 3 Amp Desktop Adpater 12V 3A Switching Transformer AC/DC Power Converter - ALITOVE DC 12V 5A Power Supply Adapter Converter Transformer AC 100-240V Input with 5.5x2.5mm DC Output Jack for 5050 3528 LED Strip Module Light --- ## 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.co.za/products/137809148-12v-3a-36w-ac-dc-power-supply-adapter-100v-240v](https://www.desertcart.co.za/products/137809148-12v-3a-36w-ac-dc-power-supply-adapter-100v-240v) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-15*
