Hi, I recently bought a set of Bluetooth airbuds. Checking the manual I saw that they need to be charged at 5V and 500mA.
The thing is I don't have a charger that outputs 500mA. Is there any way of charging it through the USB port of a PC? By what I know USB 3.0 supplies a maximum of 900 mA so, is there a way of controlling that power output?
if it is putting out 900mA and your device only needs 500mA then you got what you need, no adjustments to the device or power being sent to it is needed. same goes for a laptop power supply 60w laptop and a 90w power supply, or a light bulb. 110w supply and a 10w light bulb, it does not blow up when you turn it on, it only draws the amount of watts it needs to work.
The manual says that the current must be <= 500mA. The batteries are sensitive, I guess.
then do some research on electricity, and electronics and how it works. I am not going to say it will not hurt them ...due to liability issues, though you can read this too.
