A transportable system has a power distribution system with a power distribution unit and a power module. The power module is configured to provide energy in the form of rotational motion to the power distribution system. The power distribution unit has one or more power converters and an input connection. The power distribution unit is coupled to the power module, and the rotational energy from the power module is transferred to the one or more power converters via the input connection.

A drive system comprises a DC-DC converter that is arranged to receive an input voltage from a battery having a nominal battery voltage. The DC-DC converter has a first mode of operation in which the DC-DC converter generates a regulated output voltage from the input voltage and supplies the regulated output voltage to a load, and a second mode of operation in which the DC-DC converter is by-passed such that the input voltage from the battery is supplied to the load. A controller is arranged to compare the input voltage to a threshold voltage that is less than the nominal battery voltage. The controller operates the DC-DC converter in the first mode when the input voltage is less than the threshold voltage, and operates the DC-DC converter otherwise.

The solar tent comprises a canopy tent with integrated solar panels into the roof of a medical tent design. This technology allows the tent to capture solar energy, and convert it into electrical energy which can then be used to power lights, medical devices, and other equipment. This technology is foldable and collapsible to allow the tent to be both deployed and stored rapidly. The solar tent helps medical professionals overcome the challenges of lack of sufficient electricity while operating from a canopy tent, in the face of COVID-19.

Power supply equipment includes an adapter which converts power from a power source to DC power for powering an electronic device. The power supply equipment includes circuitry which produces a data signal for use by the electronic device to control power drawn by the electronic device. A cable extends from the adapter. The power supply equipment further includes a tip which has an input side and an output side. The input side of the tip is detachable mateable to the cable. The output side of the tip is detachably mateable to the electronic device. The tip output side has a shape and size dependent on the shape and size of a power input opening of the electronic device. The tip provides the data signal, as well as the DC power, to the electronic device. Different tips may be used to provide appropriate data signals to different electronic devices.
