20Pcs Mini DC Adjustable Power Supply Buck Module Step Down Module
A part of the review has been auto-translated.
Product corresponds to the description. Processing and quality are very good. I have bought these modules several times. Am very satisfied with them. Have processed these modules several times, they work reliably. Until today I had no failure. I can highly recommend a purchase.
These are an incredible value. 96-98% efficiency means NO HEAT and NO WASTED POWER.. the days of the TO-220 1A regulator with heatsink and fan are over. It brings shame to what I used to think was an efficient power supply after matching transformer, rectifier, heat sink, and convection cooling. There are two; a 1.8A and a 3A and they are both terrific regulators - power supplies made simple! ** And just as a side note: they arrived faster than a similar order for FETs from Amazon!
In conformity with order. Still untested, but it is the second purchase of the same item. Well packaged
Product corresponds to the description, Good quality and workmanship. Very small assembly, works great. Price performance is very good.

These are useful in so many places so I bought 20. Tiny size compared to XT60 and XT30 in the photo.
Second time I buy from the same supplier. good product, good price. One caveat, larger lots do not necessarily mean lower per unit cost, you have to account for shipping cost. The picture shows a unit already mounted.
received my item. thank you.
very good packaging, each circuit board is in one package. Hasn't had a chance to test them yet.
Good quality.
