Abstract: In one example in accordance with the present disclosure, an electronic device is described. An example electronic device includes a battery to provide power to the electronic device, a keyboard, and a keyboard-based charger to charge the battery by actuation of the keyboard. The example electronic device also includes a processor and memory storing executable instructions that when executed cause the processor to determine that a battery power is less than a threshold battery power and a power source is unavailable. The instructions also cause the processor to activate keyboard-based charging to charge the battery in response to determining that the battery power is less than the threshold battery power and a power source is unavailable. The instructions further cause the processor to generate a user notification to request keystrokes on the keyboard to charge the battery with the keyboard-based charger.
