Works great and just plugs into the lighter socket on the dash. I take it and the bubbler off for transport of the bucket and let the batteries take over when I'm not near a 12vdc lighter socket. Works great. ### ⭐⭐⭐⭐⭐ Very easy to use and the LED output is nice *by M***R on Reviewed in the United States on December 22, 2014* Very easy to use and the LED output is nice. Had one blow when wires crossed but that was my fault. Highly recommend the use of a voltmeter if your applications are voltage specific since this only goes to tenths. ### ⭐⭐⭐⭐⭐ It does a great job! Small enough to fit in the place ... *by T***R on Reviewed in the United States on March 20, 2015* I bought this to convert some of my battery operated small devices to work on 12 V DC. It does a great job! Small enough to fit in the place of 2 D battery compartment. --- ## 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.vu/products/14790052-yobett-rrlm2596-adjustable-4-0-40v-to-1-25-37v](https://www.desertcart.vu/products/14790052-yobett-rrlm2596-adjustable-4-0-40v-to-1-25-37v) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-06*
