BACKSTORY: Universal charger or common charger refers to various projects to standardize the connectors of power supplies, particularly for battery-powered devices.

Since the publication of the USB Power Delivery standard in 2012, and the USB-Cconnector in 2014, USB-C has become a widespread standard for charging mobile phones.

A situation where a variety of connectors proliferate has several disadvantages. It is inconvenient and costly for users, and causes unnecessary electronic waste when users change devices, due to the disposal of chargers still in working order.^[1]

Legislation for mandatory charger standards has been criticized, particularly by Apple, who argued in 2019 that a single standard would “freeze innovation rather than encourage it.” Apple also noted that if a universal standard was not an existing standard, adoption of a new standard would lead to increased e-waste.^[2] Apple used their proprietary Lightning connector, from which USB‑C is derived, for many devices, but has used only USB-C in new products since 2023.

BACKSTORY: A battery charger, recharger, or simply charger,^[1]^[2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging after the battery has been fully charged and can be recharged by connection to a constant voltage source or a constant current source, depending on battery type.

Simple chargers of this type must be manually disconnected at the end of the charge cycle. Other battery types use a timer to cut off when charging should be complete. Other battery types cannot withstand over-charging, becoming damaged (reduced capacity, reduced lifetime), over heating or even exploding. The charger may have temperature or voltage sensing circuits and a microprocessor controller to safely adjust the charging current and voltage, determine the state of charge, and cut off at the end of charge. Chargers may elevate the output voltage proportionally with current to compensate for impedance in the wires.^[3]

A trickle charger provides a relatively small amount of current, only enough to counteract self-discharge of a battery that is idle for a long time. Some battery types cannot tolerate trickle charging; attempts to do so may result in damage. Lithium-ion batteries cannot handle indefinite trickle charging.^[4] Slow battery chargers may take several hours to complete a charge. High-rate chargers may restore most capacity much faster, but high-rate chargers can be more than some battery types can tolerate. Such batteries require active monitoring of the battery to protect it from any abusive use.^[5] Electric vehicles ideally need high-rate chargers. For public access, installation of such chargers and the distribution support for them is an issue in the proposed adoption of electric cars. (SOURCE: Wikipedia)

BACKSTORY: Mobile accessories include any hardware that is not integral to the operation of a mobile smartphone as designed by the manufacturer, and adds utility to the mobile phone.

Mobile phone chargers have gone through a diverse evolution that has included cradles, plug-in cords and obscure connectors. However, devices built between 2010 and 2020 generally use micro-USB connectors, while newer devices tend to use USB-C. Apple devices often use proprietary connectors.

External batteries are most commonly stand-alone devices, which can be cabled to the phone’s primary charging connector. (SOURCE: Wikipedia)
