The media could not be loaded. I got the PM3-100 (100amp) to replace my lame 13.1v 45amp charger-converter in my class A 2001 Rexhall motorhome. The new converter was easy to install, especially since I replaced a previous converter so all the wires were ready for connecting: - AC cord to an AC socket - Chassis ground to the Bonding Lug - Coach 12V (+) and (-) to the output ports on the converter - 4 screws (not supplied) to anchor the converter to the floor You can tune the output DC voltage using a screwdriver through one of the sidewalls. On the same sidewall, you can switch between 'fixed output' and '3 stages' charging. I tuned the output to 14.6v as was instructed in the manual (and also on my 6v batteries spec (I have two inline = ~12v)). The converter started charging the batteries while maintaining 14.6v on the output port which is noteworthy. The converter has a fan that turns on and off to prevent overheating. The fan is very quiet. In the attached video it sounds loud since my phone was very close to the fan but in reality, it's a weak hissing sound (similar to a computer fan). After charging the batteries for a while, the voltage switched to about ~13.5v to maintain the battery charge. Following the first few hours of use, it seems that the converter works flawlessly and according to spec. I'm very pleased with the purchase. Discovering that it's pretty small and relatively light was a nice bonus.

I've been using the 100 amp charger for a few months now to charge up a couple of 200ah lifepo4 batteries for mobile work. It takes just a little over 2 hours to fill one up (the batteries throttle the charge for the last little bit). It's been very reliable and consistent. The bolt-on outputs made it very easy to connect some nice heavy wires. The fan runs when it's charging, but it isn't super loud.

We use PowerMax Chargers exclusively at my college for our Lithium battery projects. They are very easy to install, fit easily in appropriate locations, and have an acceptable noise level for the strong output that they produce. The voltage outputs are adjustable for precision battery charging, which assures maximum Battery life. The 7 units that we have in the various classroom settings at my college have been running perfectly for over 4 years now, charging 2, 3, or 4 12 volt Lithium batteries in parallel, (usually 4 to 6 hours runtime each night.) We would never trust any other brand but PowerMax. PowerMax has excellent support as well. The cost of PowerMax Chargers is excellent, so the value here is unsurpassed.

I bought this as a DC power supply, to run a car amps in a test setting. My setup out of the box for the powermax 100 amp was directly connected to the amp ( brx1116.1d by hifonics ) running 2 paired, svc 10 inch 300watt rms speakers ( the amp is 700watt rms at 2ohms ) . The initial power draw (just providing on-the-board power ) puts the powermax in 14.3v phase at less than 1.0 amp draw ( never noticed a drop to the powermaxs lower states (trickle charging ) during any point while the amp was powered). With no music and system powered up the converter ac/draw was less than 1 amp. It appears to be quite efficient with the conversion and power utilization. I was thinking about putting a battery as a buffer for power/draw at first but noticed zero sag in initial testing. The converter had the "new" burn in smell of transfer heat being applied to new components but didn't ever get hot, even pulling around moderate ac/DC amps. Everything seemed to run smooth in the first 30 minute test run. I would recommend this product for use on a test bench as the output power is very clean. I'm considering doing a longer test run but didn't have the time. I'll try to do a quality/sound test with a cap between converter and amp to see if there is any noticeable difference in sound, which I'll try to post later. While this is intended as a rv battery charger ( apparently ) it runs without the traditional humm. It would appears the internal components are quite different from a regular charger. To be honest, there is no sound from the unit. The setup ran like a camp without any background interference. As for rv battery charging and maintaining...I can't imagine anything but awesomeness from this unit.

great purchase. Was putting an amp in my cruiser and was going to have to place amp in engine compartment and run wires thru the boat which would have taken about 3 hours, but purchased this device and was able to save over 2.5 hours of install time. Actually saved me money.
