Worked PERFECTLY for my Fortivoice FVC-40 !!! *by C***C on May 18, 2018* I have a FortiVoice (Fortinet) FVC-40 that suffered an AC Adapter failure. Tried to get one through the manufacturer but couldn't get the part. Couldn't find anyone who sold a replacement nor could I find a part number equivalent. IF YOU NEED AN FVC-40 POWER ADAPTER - This one works perfectly!Specs call for an 18v 1.5A with barrel connector (positive inside) - This fit the bill perfectly.Would recommend this to others. Did come with US power cable. Worked perfectly right out of the box. Zero complaints. Contrary to another review I read, this DID provide full 18 volts DC at ~1.5 amps. ### ⭐⭐⭐⭐⭐ Great replacement transformer for the price *by M***M on December 2, 2019* I love my replacement transformer. It was recommended to me from a service technician from Insignia ( Best Buy ).. I had lost my transformer for my Blue Tooth speaker... Amazing, he outsourced to Amazon because Best Buy did not have any in stock. Kudos to the service tech in Mexico for his recommendation... Works well and I love it. I got my tunes back .. ### ⭐⭐⭐⭐⭐ Works as it should. *by S***N on January 23, 2017* I purchased this transformer to use for a power supply for an LED work light that I own. It was an "experiment" that worked out well. The power supply had no problem powering the LED load that was about 1/2 of the transformers capacity. It is a good value for the money. Keep in mind that this is a DC output, and is made to power only 12 volt loads. ## Frequently Bought Together - UpBright New 18V AC/DC Adapter Compatible with ID: 2.5mm OD: 5.5mm Barrel Round Plug 2.5 mm X 5.5 mm 18 Volt 3 Amp 18 V 18.5V 3A 18VDC 3.0A - 3.5A (Positive Inside) Power Supply Cord Cable Charger PSU - HiFiBerry HighPi Raspberry Pi Case - Raspberry Pi4 - Raspberry Pi 4 Model B 2019 Quad Core 64 Bit WiFi Bluetooth (4GB) --- ## 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.dk/products/38145892-new-18v-ac-dc-adapter-compatible-with-id-2-5mm](https://www.desertcart.dk/products/38145892-new-18v-ac-dc-adapter-compatible-with-id-2-5mm) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-05-01*
