New Power Supply




The benefits of USB-C are now finally realised…. I have switched from having a small USB charger and a PC powerbrick over to a single, powerful power supply to convert mains power to what I need for gadgets…

Tommox Power Center 4:

Small size (a little bit bigger than my laptop “brick”, but with enough power to charge at max speed my laptop, phone, headhones, powerbank and Solis Roam (chained)

Rated power:75W
USB-C PD Output: 5V3A, 9V3A, 15V3A, 18V3A, 20V3A 60W max
USB-C QC 2.0 Output: 5V 2.4A, 9V 2A, 12V 1.5A
USB-A QC3.0 Output: 3.6-6V/3A, 6-9V/2A, 9-12V/1.5A
USB Standard Output: 5V2.4A Max per port
Dimension: 103.44*72.05*27.39mm
Here it is with the cables I normally keep with it. A beefy 1m 60W C-C cable for laptop or sometimes my phone. Short cables for charging headphones or powerbank or phone.

So far (trips to Japan, Korea, Milan etc. it has worked flawlessly. The blue light is not too bright, and the unit does not get very hot so seems safe to keep on the floor when charging using aircraft power….
Reasons to change?  If it could be even smaller (New Gallium Arsenide power conversion is just round the corner). Maybe if it had an integrated Qi charger that would be nice – but not essential.
