If you are anything like us you are constantly looking for somewhere to plug in your phone charger, which often evolves pulling the sofa out the way and unplugging that table lamp on the side board. Wouldn't it be easier if you could just plug your phone into the table lamp? This project is based on a 12v LED table lamp and a 5V USB DC 7V-24V to 5V 3A Step Down Buck Converter module.

Step 1: You Will Need...

Depending on the table lamp you are going to use to house your charger f, your design will vary and thus the parts and equipment required will to. Below is a generic list based on what we used, it is not complete but should give you a pretty good idea.


  • Low voltage table lamp (anything between 7-24v will work, we used a 12v one from B&Q).
  • 5V USB DC 7V-24V to 5V 3A Step Down Buck Converter Module.
  • Snap-in Miniature Round Rocker Switch Black (to turn the light on and off).
  • Wire, we used speaker cable
  • Hot Melt Glue
  • Solder
  • (Optional) Sticky backed felt.
  • (Optional) Heat shrink tubing
  • (Optional) Larger AC adapter, without this you will not be able to charge and use your lamp at the same time, one capable of supplying 650mA and 3000mA is best with appropriate connector for your lamp.

Tools & Equipment:

  • Basic hand tools e.g. screwdrivers, wire cutters, craft knife, spanner, a hammer, pliers etc.
  • Something to cut the slot in the lamp base for the usb socket case with, most likely a Dremel.
  • A drill and drill bits for the hole for the lamp power switch, the biggest drill we had was only a 10mm a step drill would of made things a lot easier!
  • Small round and flat files,to tidy up your drilling & cutting.
  • Soldering iron.
  • Multimeter.
  • Hot Glue gun.

You will of course also need somewhere to work, best not make this on the dinning room table, not unless you want to be explaining the soldering iron burns!

I made it with some copper wire fairy lights in a glass cloche on a solid block of European beech that I hollowed out with a drill press and router.
<p>Awesome Instructable. Very helpful for making my own. I used a regular 120v lamp that I had on hand. I then used the guts from a regular old USB wall wort that I disassembled and then implanted into the base. I copied your idea with the rocker switch, which controls whether power gets to the USB charger chip or not. It is set up so I can turn on/off the lamp and the charger individually. Thanks for the post, very helpful! </p>
Great to see your version, I would imagine a few will be built like this to get around the low voltage lamp restriction.
<p>Nice work!</p><p>Just a note to add that the lamp needs to be 7-24V DC, just in case there are any whacky AC powered ones out there.</p><p>What's the feasibility of getting two charger sockets in there?</p>
<p>Thank You! Indeed you are correct it needs to DC although it would be pretty easy to add a rectifier to a low voltage AC lamp if need be. With the donor lamp we used things might be a bit tight to fit in another charge socket but it could probably be done especially if you have a lamp with a larger base.</p>
<p>Nice job - this would be a great addition to a bedside light as well, especially in hotels.</p>
I actually have seen that in a couple of the hotels I've stayed it. I was and still am amazed by them haha
<p>Did the same project last year. What's really kicking @$$ about charging lamp is that it takes only few minutes to make and solves the headache of wire management.</p><p>In addition to being a fully functional charger it also works as a PSU for your electronic projects!</p><p>And, there's the link to full project log.</p><p><a href="http://www.techpowerup.com/forums/threads/charging-lamp.195797/" rel="nofollow">http://www.techpowerup.com/forums/threads/charging...</a></p>
