I've only used it a handful of times so far but it's so awesome that I thought I'd chime in now.
I've used LOTS of PSU's over my 30 yrs in RC and none before have been this awesome.
Why is it awesome?
It's the smallest and lightest I've ever had. Almost half the size of my Cosel 24V 70A and 4.3 lbs instead of 8+ lbs.
Not a big deal unless you're building a charging case for the field and want it to be as light as possible. Fits in the bottom of my Pelican 2200 Storm Case with room for the PL8 on top.
Just charged at the field with charger drawing 20A for (2) 6s 5000mAh packs and the PSU was only pulling 5A (per Kill A Watt meter) from the 1000W Yamaha generator's AC.
The fans are load-controlled too so you'll only hear them if you have to.
Superior product and service from David at Progressive!!!
- This power supply was purchased after over a month of research online. It's surprisingly compact, and is half the size of the 12v 80amp power supply it is replacing. I finally can get all the power out of my chargers, and the supply doesn't even get warm. Highly recommended. Worth every cent.
Good service and fast shipping. Was able to help me to save some tax.
This power supply can handle two thunder power 820dc chargers at 14 amps each port, drawing 1640 watt peak from wall outlet. It charges two sets of 4400 mah packs from storage like 13 minutes, great for rushing out for a flight or two.
Very happy on the purchase.
