A neck-mounted power bank is suitable for being hung on a user's neck to supply power to an electronic device. The neck-mounted power bank includes a body, a battery, and a pair of adjustable assemblies. The battery is disposed in the body. The pair of adjustable assemblies are respectively connected to two ends of the body, and define a wearing space with the body. The pair of adjustable assemblies can be rotated relative to the body so as to adjust the size of the wearing space. Each of the pair of adjustable assemblies includes a rotate arm and an angle arm. The rotate arm is rotatably connected to a corresponding end of the body. The angle arm is connected to the rotate arm and has a contact surface. The contact surface is suitable for contacting the user's neck.

A packaging film includes a packaging portion and a pulling portion, and the pulling portion and the packaging portion are demarcated by a tear line. When the pulling portion is pulled, the tear line is disconnected, and the pulling portion is separated from the packaging portion. In a packaging face of the packaging portion, an area packaging a side wall of the battery is a glue-free area, and other areas are provided with a first adhesive. An adhesive face in the packaging portion is provided with a second adhesive. A part of the packaging face in the pulling portion is provided with a third adhesive, and the adhesive face in the pulling portion is a glue-free area.

A system is provided with a set of removable battery packs and a set of power tools each including a motor, a controller, and a battery receiving portion. For each power tool, the controller is configured to identify a type of battery pack coupled to the battery receiving portion and limit a maximum amount of electric current drawn from the battery pack by the motor based on the identified type of the battery pack. The greater a ratio of an impedance of the motor to an impedance of the battery pack, the less the controller limits the maximum amount of electric current drawn from the battery pack such that for a given battery pack of the set of removable battery packs, the lower the impedance of the motor, the more current the motor draws from the given battery pack.

A smart key for a vehicle includes: a base part; a first terminal part coupled to the base part and which makes contact with a first electrode of a battery so as to be electrically connected to the battery; a second terminal part disposed facing the first terminal part to form an insertion part where the battery is inserted and which makes contact with a second electrode of the battery to be electrically connected to the battery; a separation prevention part which extends from the second terminal to the base part and which abuts the side surface of the battery to prevent the battery from separating from the insertion part; and a pressure applying part which is connected to the second terminal part so as to enable contact with the battery and which maintains contact between the battery and the separation prevention part by an elastic restoring force.

A battery-based portable power supply includes a battery pack that is configured to protect the batteries and components therewithin. An outer tube protects inner components from impacts that can be expected in transport and usage. A suspension system within a battery pack of the power supply protects the batteries from jolts and bumps. The batteries can be removed and replaced. A switch structure for actuating the electrical outlet is disposed within the battery pack. The switch structure is actuated by compressing the battery pack from outside.

A portable food preparation assembly for storing and subsequently cooking food items includes a lunchbox that has a first compartment and a second compartment. The first compartment is defined by a thermally insulating material to store food items and ice for cooling the food items. A microwave oven is integrated into the lunchbox for directing microwave energy into the second compartment to cook food items positioned in the second compartment.
