The field of the disclosure relates generally to portable power systems and, more particularly, to systems and methods for a portable power station and charger.
Audiovisual equipment is often positioned across a stage and are powered by portable and remote power stations. Equipment such as strobe or continuous lighting, sound systems, recording systems, monitors and cameras can require a continuous power draw for multiple hours. By way of example, a camera can draw upwards of 70 watts for a period of 8 or more hours, or a light can require a power draw of 200 watts. Such high loads over long periods of time cause the power station to overheat which results in premature degradation of the battery pack module. To reduce overheating, active cooling systems such as fans are incorporated into the power station. However, active cooling systems are prone to moisture and particle ingress, which can damage electrical components of the power station as well as the equipment powered by the power station.
Furthermore, replacement of the battery pack module is required at regular intervals to maintain peak performance of the power station. To replace the battery pack module, the user can manually disassemble the power station, which can result in improper re-assembly. Alternatively, the power station can be sent to the manufacturer for refurbishment, which increases operational costs of the user.
Thus, there is a need in the art to provide a power station having improved cooling and ease of re-assembly while reducing moisture and particle ingress.
