These requirements cover portable and movable power packs provided with one or more batteries or electrochemical capacitor modules. If provided with a battery@ the battery shall be either a lead acid or lithium ion battery. The power packs are provided with one or more inputs as shown in 1.2; and they are provided with one or more outputs as For power packs provided with a booster function@ the power packs are used for providing a temporary power source to a depleted land vehicle battery@ rated 12 or 24 V@ to provide emergency starting power. Power packs shall be provided with one or more of the input options as shown below: a) Cord and plug connection@ rated at 240 V ac maximum@ to and/or 60 Hz; b) Photovoltaic panel or device with inverter; or c) Vehicle adapter@ rated 12 V dc maximum. Power packs covered by this outline shall be provided with one or more of the following outputs@ with the exception that one of the outputs in items (a) ?C (c) are provided as a minimum: a) Booster cables to provide a temporary power source to a depleted land vehicle battery@ rated 12 or 24 V@ to provide emergency starting power or recharging of the external vehicle battery; b) One or more receptacles@ each rated no more than 125 V ac@ 15 A; c) DC output connectors rated 24 V dc maximum; or d) Standard USB port outputs. With reference to 1.3@ power packs may also be provided with additional systems such as an air compressor (tankless type) for inflating tires or other inflatable items@ or with a light to act as warning lights to oncoming traffic@ as a flashlight@ or the like. These functions are also powered by the internal battery. These requirements cover the power pack options such as lights@ voltmeters@ internal air compressor assemblies@ associated gauges@ inverters@ vehicle adapters@ and internal batteries@ as well as the charging of the internal batteries@ when these options are integral to the power pack. These requirements do not cover wiring or cabling used in the recharging function of electric vehicle recharging equipment.
