I have used this adapter to test a small toy helicopter (it was missing its lithium polymer battery pack) and it ran just fine, though I have never used it on a motor that needed more than 12 volts to operate. You can always connect a capacitor in parallel to the line, let the adapter charge it up, and then when you start the motor, the initial current draw will be alleviated by the capacitor and the adapter will then give a constant current flow for operation. if there is too much power draw the device will temporarily shut of and then reboot after 5 seconds after all loads have been disconnected. I have short-circuited the adapter a fair few times (mostly on accident) without any long term issues that I can tell. **Q: The readout stays at 24.5 and will not change. Can be turned on and off but turning the dial does nothing otherwise. Is this a faulty unit? Thanks** A: It Sounds Like The Potentio **Q: I think small short cable is Not an extension but is a reverse polarity cable for devices that need reverse polarity otherwise would cause damage?** A: The short cable is identified as changing the polarity of the tip from center positive to center negative; useful for guitar effects pedals which typically are CN. I don’t think Sergio 2020 is correct in their answer. I have a separate adapter cable that fulfills this same purpose and does so safely for my effects pedals. **Q: What awg wire is run in the dc cable running from the power supply to the dc receptacle?** A: It appears to be around 14 ga, which is common residential wiring. Hope this helps. ## Frequently Bought Together - SHNITPWR AC Adapter 120W Universal Power Adapter 4V 5V 6V 9V 12V 15V 18V 19V 20V 24V Adjustable Switching Power Supply 100V~240V AC to DC 4V ~ 24V 5A Converter with 14 Tips & Polarity Converter - aceyoon 38 PCS Universal Laptop DC Power Adapter Tips 5.5 mm x 2.1 mm DC AC Power Adapter Kits Connector for Thinkpad Power Supply Plug Jack Sets --- ## 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.tn/products/273756723-shnitpwr-ac-adapter-120w-universal-power-adapter-4v-5v-6v](https://www.desertcart.tn/products/273756723-shnitpwr-ac-adapter-120w-universal-power-adapter-4v-5v-6v) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-25*
