AZDelivery 220V to 3.3V mini power supply compatible with Raspberry Pi including E-Book!

We are using this to power our blink doorbell. Fairly easy to do if you are ok to strip wires ‘ solder etc. saves buying expensive lithium batteries at eight pounds a pair

I have not had time to test this yet, but it looks good. What I don't understand though is the design. Why on earth would you put the output pins so far away from each other when 5v at 0.5Amp is safe to touch, but put the two pins for the very dangerous 230V AC very close to each other? Surely the AC pins should be far apart! Very odd, but again, it looks nice.

First one worked for about 10 minutes.Second one worked for less than a minute.Third one seemed OK under 0.5A load for a few hours but had to return with the others.

Seems to be working very well, no real problems to date

Excellent product datasheet!Easily integrated into an appropriate electronic circuit.Durable.
