Can experienced friends recommend some useful power modules? [Copy link]

I have been using power modules from Jinshengyang and Meanwell for my projects, but they are too expensive. A 2W AC-DC output 5V, input 220V power supply, the price is about 28. This is the cheapest. Experienced friends can recommend a few cheap modules. The performance is similar to this two.

The instrument is not used for power banks, and the temperature requirement is -20, 50

If the reliability, parameters, etc. are comparable, the price will be similar, unless you do it yourself.

Vico's modules are more expensive. If you want to buy cheaper ones, go to Jack Ma

Quality and price are basically proportional.
