How to shut off Led on buck converter

I am using a buck converter with a battery pack, for a usb charger. The issue is, is that the buck converter I have ( http://www.ebay.com/itm/DC-Converte...150117?hash=item3cc69bffe5:g:Q3UAAMXQTT9R0Qos ) has a led on it, which slowly drains the battery, so it loses its energy in about a day, without any load on the usb port, because of the led.

My question is, what can I do to stop this? Thank you so much for all of your help!

Disconnect the buck converter if you don't use it?

If the LED is not a relevant part of the converter (as those converters use a diode, it might be), it might be possible to simply remove it, or replace it by a better diode. I don't know the circuit they use...
Are you sure it is the LED?

well, it is a really small red light, that looks alot like a square led, with that circular diode in the middle of it, I cannot afford switches at the moment, and was hoping if someone could confirm or deny me being able to remove it, or burn it with something.

A circuit plan would help.
I could find none, in the past few hours of searching, I will take your advice and put a switch in. Thanks for your time, I appreciate the help.
