The addition of the polarity reversing patch cable is paramount in this case. I needed a charger that would be capable of charging a specific device in the opposite polarity of what most items are. This made it a very universal charger in my opinion. It works on a standard that allows me to purchase any additional charging tips that I may require for a given device. It came with several popular tips. I have only used it a couple of times and don't know the longevity yet but I am hoping it lasts for a good long time. Review: Nice one. - I bought this power supply to run 40 turnouts on N scale my model railroad. I have a lab power supply, but it has fan noise. I will be buying another to run my led lighting. I like the selection of adapters. One reason I bought this is the screw in two wire DC connector. ## Features - 3-24V Multi voltage Adjustable and Display.

There is a knob to turn to achieve whatever voltage you need down to 1/10 volt **Q: Can this be used to charge a Bluetooth speaker?** A: That's one of the things that I do with mine, Jack. I use it to charge smaller electronics including a Fugoo XL Bluetooth speaker. **Q: can you split the DC side to two wires, one positive and one negative?** A: Hmmm... I'm not sure I understand the question. The output is a 5.5mm x 2.1mm barrel connector with the center terminal positive and the outer sleeve negative. I don't know how how you'd have DC or AC current without two wires from the source. **Q: will this power a Jackery 1000W at 30V - is there a compatible connector?** A: Absolutely not. The maximum voltage output is 24v, maximum current is 36w. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Exactly what I was looking for *by D***B on April 4, 2021* I like the precision and ability of being able to dial in the exact voltage I need for a specific application and the LED display of that voltage.

One reason I bought this is the screw in two wire DC connector. ### ⭐⭐⭐⭐ Great product with limitations *by A***R on September 9, 2022* Comes with many adapters and is very handy for easy electronic testing. Accuracy is close with +- 0.2v underload Drawbacks: 1.5amps is not a great for long term use. Good for testing but not for permanent power Brick gets fairly warm during use above 9v ## Frequently Bought Together - Universal 3V - 24V 1.5A 36W Adjustable DC Power Supply Adapter Speed Control Volt Display with Variable 8 Plugs and 1 Polarity Reverse Cable Cord - NETGEAR 8-Port Gigabit Ethernet Unmanaged PoE Switch (GS108PP) - with 8 x PoE+ @ 123W Upgradeable, Desktop, Wall Mount or Rackmount, and Limited Lifetime Protection --- ## 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.de/products/125960352-universal-3v-24v-1-5a-36w-adjustable-dc-power-supply](https://www.desertcart.de/products/125960352-universal-3v-24v-1-5a-36w-adjustable-dc-power-supply) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-04-24*
