And checked on videos online to see which one is best at this price range. It does so much more than the cheapest ones. If you set the current limit, and it is reached it tells you it is in current limit mode and then the voltage drains down. You can also set it to shut off with Over Current Protection, where an alarm will sound and it will cut power. I found the leads more than adequate with the alligator clips and spade terminals, which I prefer to the banana clips. Readout is nice and clear with a fairly good update rate so you can see changes happen quickly. You can even adjust the baud rate in the options to make it quicker and lower the screen brightness. USB port also came in handy, although you cannot read the current draw for this, and the manual doesn't mention what it's limit is. I powered an Arduino and charged a phone off it, so it was fit for purpose. Adjusting everything is easy with pushing the knobs to change which digit you want to adjust to do fine or rough adjustment from 1 / 0.1 / 0.01 etc. It would be nice if it remembered which digit you were last on though, as it keeps defaulting to fine adjustment and takes a bit of remembering to push it first before turning it. Only thing is the beeps are a bit annoying, which wasn't a problem at first, because the manual lets you turn it off by going into settings if you hold down the output button for 5 seconds. However, it doesn't remember what you set each time you turn it off so have to do it all again every time. This is silly because it remembers all your other settings, even when you unplug. I might just open it up and cover the buzzer with a piece of tape to make it less noisy. ## Frequently Bought Together - DC power supply (0-30V,0-5A) adjustable, switching power supplies, mini high precision 4-digit display with USB fast charging interface, variable lab bench power supply, output on/off/encoder knob - Cleqee 3 Pairs Multimeter Test Leads Set 4mm Stackable Banana Plug to Alligator Clips Mini Test Hook Clips Stackable Banana Plug Cables Copper Electrical Wire - Cleqee Multimeter Test Leads Kit 21PCS Electrical Test Cables with Alligator Clips SMD IC Test Hook Clips Test Tweezer Spade Plug Banana Plug Replaceable Needles Pins --- ## 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.com.au/products/449091881-dc-power-supply-0-30v-0-5a-adjustable-switching-power](https://www.desertcart.com.au/products/449091881-dc-power-supply-0-30v-0-5a-adjustable-switching-power) --- *Product available on Desertcart Australia* *Store origin: AU* *Last updated: 2026-11-04*
