hi there! Can I somehow power a small light off of this battery?

hi there, I work in valet, and I am trying to solve our peripheral power requirements for our small podium, I have everything figured out but the one last thing I need to do, is power a small LED lamp, which is charged and can operate while plugged in via a normal cell phone type plugin charger.

we have this large battery, which powers solely our backlit valet sign, I was thinking that I could somehow connect our USB charger for the small lamp on to this battery and then power both simultaneously, does anyone have any solutions for accomplishing this? I am fairly handy, but electrical questions I always need help with.

If anyone can help out with this question, I would greatly appreciate it.



Here is the battery.

I edited your post so the picture appears.

Yes, powering an LED from a battery is very easy.

Next, you'll have to determine what is a "normal cell phone charger plug". Then I have to ask why it needs to have a plug and socket and why it must be that type?

Most phones these days use a USB based connection which is 5 VDC. The battery in your picture is 12 volts. While you technically can feed 12 volts to a USB socket it is just asking for trouble. If you must have a USB socket I would install a transformer to lower the voltage and create a proper USB charging port. Or, to keep things simple just power an LED light with 12 volts.

All you need is a 12vdc to USB adapter. If you put what I've underlined into your search bar you'll get pages of them. I posted one such link below.

DC-DC 12V to 5V 24V to 5V Step Down Module Voltage Regulator with USB Cable

You will need to unplug that charger and use the 12v to USB in its place.

Ok so one of these will do! Right? Thanks.

Just connect positive and negative to battery terminals right?
