Like me! *by J***N on Reviewed in the United States on November 13, 2019* I’m just a tinkerer, and I needed something safer than the way I had to use 2 cars ,2 sets of jumper cables, clamp on to screwdrivers just to get 24V. So I’ve been using this power supply for about a week it does everything I need and I haven’t broke it yet, even though I have melted some wires, trip some breakers , but all in all I’ve had lots of fun and I’ve learned about electronics, Only regret is I wish there was someway to reverse the polarity, without having to switch the wires around maybe there’s something for that? ### ⭐⭐⭐ 3.0 out of 5 stars Might have a problem *by J***G on Reviewed in the United States on February 20, 2021* The power supply works, but seems to have some problems with the power switch. Sometimes when I turn it on, there is no power at all or there is power but no controllable output. The switch has to be toggled a few times to get it to work properly. I may have to return the unit, because clearly there is something wrong that will affect its useful life. ### ⭐⭐ 2.0 out of 5 stars High frequency ripple every 17.5 microseconds! *by D***A on Reviewed in the United States on March 4, 2019* I have to revise my opinion of this power supply. I now have an oscilloscope. The voltage output has a high frequency ripple every 17.5 microseconds. The ripple is +- 0.75 Volts about the set voltage output. see photo. This definetly would not work for any sensitive circuits.before buying the oscilloscope I like the power supply in general.The on/off power switch is flakey. Sometimes it does not work. Have to hit it several times before it finally powers up. At this time I am assuming it is the switch and not the internal circuit. --- ## 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.be/products/97882314-variable-adjustable-lab-dc-bench-power-supply-0-30v-0](https://www.desertcart.be/products/97882314-variable-adjustable-lab-dc-bench-power-supply-0-30v-0) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-29*
