Good morning.
If you have a CS4, would you please post the nameplate data for the external power supply.
Thanks

GX CS4 Exernal Power Supply

Thank you both. This is exactly what I need.
A friend bought a new CS4-i that was delivered with a faulty internal power supply. GX is supposed to send him a replacement but....
His compressor works just fine from a car battery. So, I'm going to recommend that he buy an inexpensive 600 watt power supply from Amazon to use while he waits for the replacement internal supply to arrive.

Generally, AGN won't address specific trigger words. The whole "don't talk about fight club..." There is a spam filter trigger that is contained in one of the words in your post. Part of words get caught in the filter, ipso Facto, some innocent posts are delayed for a short time.
It is a very small price to pay to keep the spammers off AGN. When was the last time you saw any of those posts?

Success. My friend purchased a 600 watt 12 volt generic power supply and hooked it up to his disabled CS4-i.
The pump works like a champ!
I bought one of these to serve as a backup in the event of power supply failure in my CS4-i.

I hate to tell ya but it wont live long it's gotta be 13v and 50amp time will tell GX pump will send you a rerplcement

Why I opted for the regular cs4. Just less of a hassle. If the converter dies just throw it away and get another off Amazon. No messing around inside the machine itself. To me the simple idea of having it incorporated inside is a minute convenience not worth the price hike.

Uodate: I have a CS4-I that worked properly right out of the box. So far, so good.
As I mentioned in a previous post, I purchased a 12 volt, 1200 watt power supply from Amazon. It's overkill but It was on sale.
I tested it this morning by topping off a tank. The compressor started and ran as usual with a few operating differences. First, the power supply output remained steady at 12.09 volts for the entire run. Assuming that the GX power supplies actually run at 13 volts as shown on the nameplates, this is a 7% drop in input voltage. The RPM of a DC motor is a function of input voltage and the compressor, which runs at 100 rpm on the internal supply, ran at 90 rpm when using the external supply. So a 7% drop in input voltage caused a 10% drop in rpm.
Second, there was substantially less perceived heat being exhausted through the radiator. I attribute this to the internal supply being switched off and not adding heat to the interior of the case.
The external supply is now back in the box and sitting on the shelf, ready to see me through in the event the internal supply fails.
I would have bought a 13 volt external supply from GX but, when I checked, they were sold out.

As per the other related thread right now (https://www.airgunnation.com/threads/cs4-power-supply.1331387/post-1957203) you may want to measure the output of your internal supply, and adjust your new external supply to the same voltage. You will have to measure & adjust each while they're connected to & running the compressor.

You beat me to it. I had planned to ask if any of the forum members would please measure and post the the output (under load) voltage of their CS4 external power supplies.

I get 13.5V using a dead head on the external power supply. This is on a 25 year old radio shack analogue meter that's very accurate.

Thanks,
The 12 volt external power supply will stay on the shelf unless needed for emergency use, such as failure of the internal power supply. I would buy a GX external supply but GX is out of stock and the GX website says "accessories" are not currently being shipped to the US due to Tariff Wars.
On the other hand, complete compressors are available and on-sale.
