Bad experience with Powermax

[John Frum]

I don't like to do this, but I feel obliged to warn the community.

I ordered a Powermax PM3-30-24LK.
Unfortunately it lasted <50 cycles.

So I talked with Graham at Powermax and he arranged a replacement.
Graham sent me another PM3-30-24LK
It was damaged in shipping so they sent me another and filed a claim with the shipper.
The second replacement was a PM3-50-24LK and I thought "nice upgrade".

Then I tested it out...
It draws ~16.8 amps at ~123 volts through a nema 5-15p as measured with my Klein cl-390 ac/dc clamp meter and confirmed with my Kincrea plug power meter.
The plug head gets uncomfortably hot to the touch and a bit soft.
I'm afraid to use it and I sure as heck won't leave it running unattended.

I suspected Powermax was ducking my calls and finally today someone just picked up and hung up without saying a word.
Like many nerds I'm not clue-full when it comes to human interactions but even I took the hint from that.

Now I've got to find another charging solution.

I have no experience with their 24V models. I'm really sorry to hear this. I've had no trouble with the 3 12V models I have, one of which is a 100A unit that is regularly used to its full capacity over the last 4 years. It does not pull more than 1700W at full output (15V/100A).

I guess I'll put a pause on PM3 recommendations.
