Good Buy for the $
Does as advert, clean power and has the amps to drive Heltec wifi kit 32, 16' neopix strip at 100% power white light (worse case).

I’d buy again
It’s a good power supply, I purchased the wrong voltage by mistake and they gave me a full refund and didn’t need to return it

Works awesome
Functions as it should for my WeBoost Overlander. It’s affordable enough to replace the cigarette car plug that I am currently using for my toy hauler. Feel solid and well made for the price. Now I can just plug into and outlet to get a better signal from my WeBoost antenna.

Review of 5 volt 4 amp power supply.
I bought this to replace a 3 amp power supply that failed in service because it was under designed for the load. It was for a grow light requiring 3 amps. This 4 amp power supply was bigger and supposed to be able to provide 33% more than the required 3 amps. I have had it on over night for 2 weeks with no problems. It looks like it will do the job. There is a video on this on youtube, just search Marty Plecki and look for it.
