Input & Output: As clearly indicated in the datasheet, you can use the module well if you have a >300mA input dc supply in 4.5-5.5V range but the maximum output load current never exceeds the 200mA at 5VDC limit.
Inside Circuitry: Although I didn’t get a worthy chance to break apart the B0505S-1W module, it came to my notice that its inside electronics is mainly based on the “Royer Oscillator” (https://en.wikipedia.org/wiki/Royer_oscillator) circuit.
As far as I know, the traditional Royer oscillator circuit only provides basic functions but once the circuit is abnormal, the module may be damaged and even cause serious consequences. At present, the module is available without a continuous short circuit protection (SCP) feature! - SCP-dat - protection-dat
