It is more reliable than 2.4W (60 ohms) and 4.8W (30 ohms) relays on the market. 2), Large capacity: 120 amp high current carrying capacity, heavy duty make/break relay. 3), Ideal for split charging or any vehicle needing a high power relay. Package Content: 1 x 120 Amp Relay Review: Works - Working great so far. I have an intermittent battery drain of 4.71 amps which drains down my batteries and at one point could not start my truck after it sat for 8 hours. I was almost 100% sure that the drain was coming from my aftermarket amplifier so I wired this up to the 8 gauge power cable. When the truck starts the relay kicks on allowing power to the amp, turn the truck off and connection is terminated. So far the amp runs when I need it and battery isn't draining. Review: Awesome relay - Great product. Works well ## Features - Coil power: 1.8w, and coil resistance is 80 ohms. It is more reliable than 2.4w((60 ohms) and 4.8w(30 ohms) relays on the market - Large capacity, high current carrying capacity, heavy-duty make/break relay - Ideal for split charging or any vehicle needing a high-power relay - Never go beyond its capabilities; try to stay 10 to 15% below what the rate is for - The size of the round stud terminals: M6/6mm ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07T35K8S2 | | Best Sellers Rank | #5,831 in Automotive ( See Top 100 in Automotive ) #3 in Automotive Replacement Accessory Power Relays | | Brand | iRhapsody | | Brand Name | iRhapsody | | Coil Resistance | 80 Ohms | | Coil Voltage | 12 Volts | | Connector Type | Quick Connect | | Contact Current Rating | 120 Amps | | Contact Material | Copper | | Contact Type | Normally Open | | Current Rating | 120 Amps | | Customer Reviews | 4.7 out of 5 stars 980 Reviews | | Manufacturer | IRHAPSODY | | Minimum Switching Voltage | 1.3 Volts (DC) | | Model | AutoRelay-12V120A1P | | Mounting Type | Screw Mount | | Operation Mode | Off | | Part Number | AutoRelay-12V120A1P | | Specification Met | NEMA, UL, VDE, cUL | | Warranty Description | 1 YEAR | | Wattage | 1.8 watts | ## Product Details - **Connector Type:** Screw - **Contact Material:** Silver - **Contact Type:** Spst - **Current Rating:** 120 Amps - **Mounting Type:** PCB Mount ## Images ![Relay 120A, 12V Continuous Duty SPST 4-pin High Power Relay - Image 1](https://m.media-amazon.com/images/I/51OvRF0lqKL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works *by D***M on April 20, 2026* Working great so far.

Works well ### ⭐⭐⭐⭐⭐ Works great, doesn't seem to be getting hot. *by C***O on April 1, 2026* Seems to work well. Doesn't get as hot as I would have expected, although I'm far from maxing this thing out either. But it works exactly as expected. --- ## 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.sc/products/146549759-relay-120a-12v-continuous-duty-spst-4-pin-high-power](https://www.desertcart.sc/products/146549759-relay-120a-12v-continuous-duty-spst-4-pin-high-power) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-07-15*
