NOTE: 3.8, 3.13 to 3.25 define terms related to cells or batteries, not terms related to power banks. 3.1 power bank A power supply system intended to be carried by the user, consisting of a cell or battery, associated circuitry and an enclosure, capable of providing a stable DC and/or AC output, with a mass not exceeding 18 kg. NOTE 1: Power banks include portable power banks and portable energy storage power supplies. NOTE 2: Mobile phones, tablet computers and portable computers with reverse charging capability (including wired and wireless methods) are not considered power banks. 3.2 portable power bank A power bank whose total rated energy of the cells or batteries contained is not greater than 160 Wh. NOTE 1: A portable power bank is commonly known as a power bank (charging pack). NOTE 2: A portable power bank generally uses a universal interface or wireless charging to charge other devices. Universal interfaces include Universal Serial Bus (USB) interfaces, etc. If devices such as portable luminaires or speakers contain batteries and can charge other devices via a universal interface or wireless charging, they are considered to have the functionality of a power bank. NOTE 3: However, any mobile charging device (charging pack, charging box, etc.) whose total rated capacity of all batteries exceeds 600 mAh is considered to have the functionality of a power bank. NOTE 4: A power supply that only supplies power to specific devices is not considered a portable power bank. 3.3 portable energy storage A power bank whose total rated energy of the cells or batteries contained is greater than 160 Wh. NOTE: Some portable energy storage products are commonly known as outdoor power supplies. 3.4 nominal input voltage The input voltage value declared by the manufacturer. 3.5 nominal input current The input current value declared by the manufacturer. 3.6 nominal output voltage The output voltage value declared by the manufacturer. 3.7 nominal output current The output current value for each port, declared by the manufacturer. 3.8 rated capacity C The capacity of a cell or battery, as declared by the manufacturer. NOTE: Expressed in amperehours (Ah) or milliamperehours (mAh). [Source: GB 31241—2022, 3.8] 3.9 rated energy The total energy of the cells or batteries contained in the power bank.
