Review on 🔌 PEMENOL 15W DC-DC Adjustable USB Power Supply Module - Convert Voltage from 5V to 3.3V, 9V, 12V, 24V, 30V - Step Up/Down Module with CVCC Buck Boost and Shell by Nap Olivas

I've found this unit to be ideal for my regular testing of electronics in various voltage ranges. Easy to use by plugging it into any 5V USB outlet, then setting your desired voltage and turning on, and the current limit is an absolute bonus. My favorites are pressure fittings for positive and negative output voltage for quick and easy connection. If that's not the best option, then the additional USB output certainly doubles as another option for quick plug and play. From time to time a product pops out and finds you personally and that product is sure to fill my cart. Highly recommended for anyone attempting small electronics repairs themselves as this can bring in the missing voltage that allows the entire device to function as it should to transform you into the great miracle worker you are accustomed to knew it was in you. do
