Made for a cable TV box, this floor-mount switching power supply is rated at 12VDC and a whopping 3 Amps, and has a 6-foot+ cord with a polarized plug and a 6-foot output cord terminating in a 5.5mm (2.1mm) center-positive female plug. Housing measures 4-1/2" x 2" x 1-1/4". UL.

These switching power supplies--called Mini Universal Notebook Adapters by their manufacturer, Velleman®--are smaller, produce less heat, have stabilized output, short circuit and overload protection. They put out up to 4.7A at 18-19.5VDC with ripple noise reduction via a 4-foot choked, non-polarized shaver cord and 2.1A via the USB port. Measure 4-1/2" x 2-5/8" x 3/4". You pick: The power supply alone has a plug that the manufacturer says incompatible with Apple products--notebooks, phones, iPads, etc. or the Adapter Plus which includes a pack of (8) plugs for Sony, HP/Compaq, NEC, Acer, Gateway, Dell and more. 

Absolutely not. Especially with these 100-120VAC input regulated switching power supplies with trim pots to adjust the output 0.5V either way, vented housings, 5-pole terminal blocks for AC in, chassis ground and DC out. You pick the 5A at 5VDC unit at 3-7/8" x 4" x 1-3/8" or the 8A at 5VDC at 5" x 3-7/8" x 1-1/2". Both have 3/32" mounting holes and are CE listed.
