Kogan USB Charger

[NickS]

I bought a mobile phone from Kogan which came in French with a EU power plug.
Kogan also supplied an Australian USB charger to make it usable.

It's a nice small one which is apparently rated at 2 amps!
I had to take it apart to see how it was made since it was Kogan branded and obviously from China.

To my slightly trained eye it looks dirt cheap made properly which is a odd combination.
The main chip is a "Stronglink SL2128". The one page Datasheet for it has some hilarious chinglish.
However the spacing between traces looks reasonably good, solder joints look very shiny, no traces break the isolation line except an optocoupler and a good looking cap and there is even an output inductor.

What do you guys think? Did Kogan actually supply something of quite good quality?

I've used the 1A version, it looks literally identical. My Post

Provided yours had the pieces of plastic/paper in the housing, i'd say it was acceptable.

I mean, the output is likely to be clean, and it seems well isolated, the input is fused, and has a cutout, BUT the traces for active and neutral are awfully fucking close. If there is a short, you're going to be hoping your house has appropriately rated breakers.

Definitely above-average.

If you Google the email address on the PCB, you get some interesting results...

load it up with a dummy load (resistor or better) and see how the voltage looks.  Maybe put a scope on it if you can.
