Hard to believe these don’t exist – Modular Laptop Power Supplies

I’m on a quest to fix the laptop cart.  Here’s the problem:  We have a few laptop carts – also known as Computers On Wheels (COWS).  Many times the laptops are used all day long and require power supplies to keep them running.

We are continually removing the laptop and power supply from the cart and then having to put the whole thing back together again, which takes about 15 minutes each time.

That puts a great deal of wear and tear on the adapters and makes for too much work to simple use a laptop for an extended period of time.

So here’s what I want:

modular power for laptop cartI’ve searched high and low for a manufacturer that builds:

  • an adjustable power supply with enough current to charge the laptops
  • Modular cables that plug into the power supply with the ability to specify the coaxial power plug

With this solution, you could have a central power supply, with individual cords running to each laptop bay.  If you need a power adapter, you can take one from a drawer on the cart without having to tear the whole cart apart to get to remove the adapter. Simple, eh?

It’s almost hard to believe that these don’t exist in the marketplace.   For years we have have modular PC power supplies where you plug in the cable you need to the PS and onto the peripheral.

It might be that there are too many options with regard to voltage or the type of coaxial plug that the laptop uses, so who knows.

Maybe I should build these things and make a million.

    I am looking for the same solution. Any luck finding it yet?

      Ron – I did a pretty extensive search and can’t find anyone building such an animal. The only solutions I found were internal power strips with each laptop p/s plugged into them, which is where we are right now. Again – it’s hard to believe that Dell, HP or Apple for that matter have not built something that meets the needs of EDU markets.
