The SMALLEST Bench Power Supply

The SMALLEST Bench Power Supply



Want to keep your power supply in a drawer when not used? Need a power supply on the go? What if you can power your power supply form a power bank? It gets even better – you can power your soldering iron to!

PD powered bench power supply. Hence the main power supply can be delivered by a phone charger, a power bank or a car adapter, this small form factor adjustable power supply is very versatile; thanks to the QC 3.0 module this PSU can power your soldering iron (i.e. TS80), fume extractor, LED light, etc.
