Share this no stars should be an option. Adapters which can also be used with motor vehicle and aircraft power see EmPower are available.
Some “universal” replacement power supplies allow output voltage and polarity to be switched to match a range of equipment.
Hqwing as inappropriate Terrible and too expensive. Adapters for battery-powered equipment may be described as chargers or rechargers see also battery charger.
