Not the same product every time

When I first received this product, I was able to unplug the USB connector and use out+ and out-. With the last order it changed completely and now I can't get the USB plug out.

Pros
  • Adopting high-performance synchronous rectification IC, transmission efficiency up to 96%.
Cons
  • Power outlet required

I bought a lot because I didn't read. You are wonderful.

Sturdy little board that steps down from 12v to 5v so I can reuse old signal wires in the walls to install repurposed tablet chargers. I bought a lot because I didn't see a few in one order. So now I'm dreaming of more things to do with extras.

Pros
  • Can be used for mobile power supply, mobile phones, tablets, etc. digital devices as a stabilized 5 V power supply
Cons
  • There are other interesting options.

Ideal for use as per design

This is a wonderful little circuit, only about 0.75" x 75", and if you plug it into a 7 volt DC supply, it's 5 volts or more, get a USB charger in no time. Using a few extra connectors, scrap wire, and pieces of PVC pipe, I made a dual-output USB charger that's powered by a lithium battery from a cordless drill. It took about an hour, not counting the wait for the paint to dry. When used for their intended purpose, these things are great. A previous reviewer tried to use them "off-label" and…

Pros
  • . Size: 42 mm x 16 mm x 5 mm (L x W x H) / 1.65 x 0.63 x 0.19 in. Switching frequency: 1.5 MHz (max.) Typical 1MHz, Operating Temp: -40Β°C - +85Β°C
Cons
  • Protection
