Hey, noob here. I hope to use this to test for my race drones, lipo chargers, and eboards. I'm wondering which one I should get?

I can highly recommend KORAD KA3005D. Its price is in the same rage as that YIHUA, but it is a linear supply, and I guess of much better quality. |

My first bench PSU was a single lead like yours are. That served me well for about a year or so, but slowly things started getting more complex and I needed to do negative voltages and other stuff, so I ended up having to purchase a second PSU with 3 outputs. While most of my stuff is very low voltage, the 3 feed allows you to do really cool things on the bread-board :) |

I have two, an old HP E3610 (none of this Keysight rubbish, as Dave is wont to say), only a single output, which is my favorite. I also got one of the dual output ones from the ITT selloff a couple of years ago (a GW Instek) which has dual variable plus a fixed 5V output. I don;t do much analog, so my need for a dual rail power supply for things like op amps is minimal at best, so I almost always end up using the HP to power my projects. If you are planning to work a lot with devices that need +/- power supply rails to function, definitely look to one of the dual output models. Until the ITT selloff came up and those units started appearing on eBay for relatively low prices, I was planning to get the Korad. I probably would have been happy with that one as well. |

Save some cash, get a couple of these little switching units. You can power them from batteries, an old laptop charger, or an AC transformer with a bridge rectifier. They work very well. https://www.banggood.com/D3806-NC-DC-Constant-Current-Power-Supply-Step-Down-Module-Voltage-Ammeter-p-1059235.html?cur_warehouse=CN |
