PowerMax Power Converters Editorial Review

The Powermax PM4 35A Power Converter is highly recommended for powering car audio amplifiers. Unlike cheap Chinese power supplies, this unit has a quiet fan and does not overheat. It is reliable and delivers excellent performance. However, some customers had issues with burned electric smell and packaging. It is a direct replacement for failing converters in RVs and is well-made. The unit can get hot during charging, so good ventilation is necessary. The 75A model is suitable for use with a generator. The fan can be noisy, but overall, it is a good replacement option. However, some customers experienced burnouts under light use.
