scope:

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 shown in 1.3. 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 24 V maximum, 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;

c) Vehicle adapter, rated 12 V dc maximum; or

d) USB input port (can also act as output port).

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) are provided as a minimum:

a) Booster cables to provide a temporary power source to a depleted land vehicle battery, rated 24 V maximum, 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.

Power packs may be considered suitable for outdoor use, suitable for temporary outdoor use, or suitable for indoor use only. Outdoor use packs can be used outdoors with no restrictions. Temporary outdoor use packs may be used outdoors but should be used carefully in wet conditions and always stored indoors. Indoor use only packs must be stored indoors and used indoors and cannot be used outdoors at any time. A power pack with a booster function shall not be considered indoor use only under any conditions.

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
