How to shut off Led on buck converter

AI Thread Summary
The discussion centers on a buck converter used for a USB charger that has an LED indicator, which drains the battery when not in use. Users suggest that removing the LED or replacing it with a better diode could potentially solve the issue, though there is uncertainty about the LED's relevance to the circuit. One participant expresses a desire for a circuit diagram to better understand the components involved. Ultimately, the consensus leans towards installing a switch to disconnect the converter when not in use as a practical solution. The conversation highlights the need for effective energy management in battery-powered devices.

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-Converter-Step-Down-Buck-Module-7V-24V-to-5V-3A-5V-usb-output-power-adapt-/261030150117?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 a lot 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.
 

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Electromagnet magnetic field issue'

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
