I bought a Chinese p/s on Ebay that was advertised as a Led light p/s which apparently are heavily used in China. The one I bought was the 20 amp version adjustable from 12-15v. Five months ago I paid $25.92 including shipping. Now the 20 amp is selling for $22 and the 30 amp for $25.

Here is the kick: This is a high quality p/s. Made like a brick, no hash and I used it all summer in an unairconditioned shack in Florida with no problems. It has an inaudible fan. It has a 110/220 switch that has to be set correctly and you plug it in using a 2 prong ac line. One line to L and the other to N (since it is ac it doesn't matter which is which).

On top of all that is it arrived in 14 days from China sufficiently packed. I highly recommend this power supply and vendor named Mall-ata888. You find his Ebay p/s page by typing seller:ata-mall888 then you'll see all supplies on one listing then use the drop down box for the voltage and amp you prefer. This was one of the best ham radio purchases I have made.

I'm very interested but when I searched for the seller all I got was this -

The seller User ID you entered was not found.

BTW:

I have no affilliation with this guy. Don't speak Chinese, don't even eat Chinese (hungry 20 minutes later). I just had to share this. Not good for the US economy but great for hams.

You have to type it as I instructed. He is not listed under ham radio power supplies. It will be 4th item down.

I think you got it backwards once -

Search for mall-ata888 - not ata-mall888.

It's $27.98 now for 12V 30 amp. Ebay has something now where the price changes a few dollars up or down - still a steal.

N5INP,

I'm the cheapest ham ever. To hang antennas I tie short lengths of used fishing line together so I don't have to buy more - I don't want to pay $2.95 at wm for a new spool. I use pennies for fuses like back in the 50s. To avoid buying audio plugs from rs I've soldered wire to the jack leads on my transceiver and computer  Tongue.

the Chinese sellers are playing like eBay was a bazaar.  you will generally find they introduce an item with slightly different packaging and prices that range some 10 percent or so around a core price.  they are obviously trying to see how much they can nick ya for.  they revise their pricing until there are no more suckers taking the highest prices, and then it becomes lots of 1 "46 availiable" changing to lots of 1 "3 availiable."

the prices creep up as the pack around the item decreases, and then they introduce the concept of artificial-rarity into their marketing.

clever dudes.

Just a few questions to anyone in the know. Can you somehow internally or externally adjust the voltage to a more usable 14.2 or so volts? How do they handle regulation under load? Ripple?  I know that the hash issues were already mentioned. Is the input voltage selectable or like most switching supplies is input voltage within a range, let's say 100-250 volts AC? I could certainly go look this up for myself but would rather hear from someone that has actual experience.

The power supply is a computer ATX supply?
