The PowerMax PM3-55LK is a 12v 55 Amp charger converter power supply. The unit features a selector switch that allows you to switch between 3-Stage Smart charging or Fixed Output Mode* for faster-charging needs.
The PM3 Series converters can accept a wide voltage input of 105 to 130 VAC. The unit weighs approximately 6 lbs and is an excellent option for RVs, radios, backup power supply needs, and smaller-sized pumps! Because of its high demand the unit is fan cooled and should be installed in a well-ventilated area where it will be safe from the environment.
Power Max has designed and built a powerhouse charger/converter using only the best in manufacturing technology. Capable of providing a constant load demand of up to 100% of its rated capacity, the PM3 series converters are among the best. Pumps, fans, motors, and radio equipment will run without problems on the PM3 converter/charger.
Note:
*The Fixed Output Mode does not offer smart charging and simply outputs at the fixed voltage. Users are highly recommended to use the 3-Stage charging mode for safe charging.

Great Battery Charger
I bought this charger/converter to charge the LiFePO4 battery on my off grid system. I needed a fairly robust charger for my 325AH battery and I had to be able to adjust the output to the proper voltage. I only have to use it if we have no sun for 3 days and have only used it once since I received it 2 weeks ago. This charger performed well and replaced the 2.2 kW needed to refill the battery in about 3.5 hours, which is right in line with the specs of the charger.
Be advised whenever charging a LiFePO4 battery do not leave it unattended. This charger is not specifically made to charge this type of battery; if you know
the specific settings for your battery and make the adjustments this works great and costs about a quarter of what a charger that is made specifically for these types of batteries.

Excellent product
I installed in a rather restricted place, but made ducts for the intake and exhaust. The converter is well-made, quiet, and doing an excellent job.

Have not really put this to the test yet but it seems to be keeping the deep cell charged which is what I was looking for. Product delivered on time, price reasonable.

Works great just like the one it replaced.
This product replaced one that was burnt up due to a power input overload. It is doing the job and working perfectly just like the old one before the power problem.

Excellent
This works exactly as I hoped. I no longer have to change out batteries while running my trolling motor while bowfishing. I had to be a little creative in placement as it is not waterproof. Great product.
