$12.99
Ideal for any device drawing up to 2A
Fully regulated to deliver constant DC power
Rotary selector switch selects 3, 41/2, 6, 71/2, 9 and 12V
Power projects or small battery operated devices
Color coded binding posts makes connection easy
Ultra-compact, lightweight design
Power on LED indicator
Dimensions: 5 3/16" (L) x 2 5/8" (H) x 3 7/8" (W)
Not continuously variable and you might be able to go inside and tweak the 4-1/2V output such that it's 5V. Regardless, for the price it would be a handy addition to most people's benches that are just starting out.
I went ahead and ordered one, I hope it will be easy to convert that 4.5 to a 5V. Worst case I can sneak a 7805ACT (good for 2.2A if well heat sinked) regulator inside and add an extra binding post.
When ordering 7805 regulators I usually get these due to the high current capability: http://www.mouser.com/ProductDetail...ACTG/?qs=sGAEpiMZZMtqO%2bWUGLBzeDCqR6jt/BN%2b and they have the same 7V input voltage requirement as the supposedly low dropout versions: NCP7805TG
