Jeff, caution. Laptop power external supplies are designed to be followed by precision internal regulators that handle the logic voltages and charging the battery. The external supplies are not well regulated and can be quite noisy. They may not be the best supplies for ham rigs. 73 Fred, AE6QL

I found that Toshiba supplies are specified 15v and ranged in current capability from 2.5 amps and up. Dell, Lenovo, HP, Acer, Asus all use 19v supplies. Those Toshiba supplies are very small.
