Seems scary to use the 24g broadboard style jumper wire on them for 120v AC** A: Those wires work fine. Not enough current going through it to need anything bigger ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good *by S***N on May 13, 2026* Do the job. I have bounced the power on mine many time and no issue. Constant voltage and well packaged me. ### ⭐⭐⭐⭐⭐ Tiny and functioning well *by S***N on April 27, 2025* Bought less than a month and tried one with a laser diode works out pretty well so far. Will see how long it goes. Based on the light condition, it’s pretty steady means the output voltage is steady as well. ### ⭐⭐⭐⭐⭐ Good little power supply *by S***N on November 2, 2025* Good product for the price, really. Not an instant supply when turned on, takes about a second and slow drain when off if that is an issue for your project. Someone here says is not breadboard friendly. It is, with a small modification. The supply rail of the breadboard is most likely continuous supply of power along the breadboard. You only have to snip the track underneath the bridges like sections on one end of the breadboard the mini power supply will fit perfectly sideways with the dc prongs on each side of the bridge ## Frequently Bought Together - EC Buying Mini Step-Down Power Supply, Intelligent Home Switching DC Power Module AC DC Isolated Power Module 220v to 5v, HLK PM01 AC DC Converter 220V to 5V（3PCS） - Acxico 5Pcs 5V 700mA Board Module Mini AC-DC 110V 120V 220V 230V to 5V 12V Converter Board Module Power Supply - AEDIKO 4pcs DC 5V Relay Module - 1 Channel Relay Switch Board with Optocoupler Isolation, High or Low Level Trigger --- ## 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.in/products/456578558-mini-step-down-power-supply-intelligent-home-switching-dc-power](https://www.desertcart.in/products/456578558-mini-step-down-power-supply-intelligent-home-switching-dc-power) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-06-18*
