I love these little boost converters, they're so useful, in a small package (I'm sure you can find smaller ones if you really need, but these aren't large by any means) and I love the very precise output voltage adjustment. The microUSB port is incredibly useful, just be careful if you are using the through-hole pads for your power source, that you don't accidentally plug into that microUSB port as well. I haven't tested it this theory yet, but I can only imagine it's connected in parallel with the input through-hole pads so that if you plug a USB cable in, you're either supplying a higher voltage than you want, which could boost your output voltage and fry your device, and/or possibly sending that 5v directly to your power source, which could be bad if it's a battery or power supply that doesn't have protection against a reverse current. Overall, I wouldn't hesitate to buy more.Read full review

These things have a flaw in the circuit design. They will smoke a d get very hot or outright catch fire with just 3.5 volts. Please do research online before making any purchase of these things. I would research making them yourself the circuit is simple enough.

Unit works very well. I used it to replace an old lead acid battery on an outside table lamp with a single (2cell parallel) 3.7V Li-Ion 18650 battery. I needed 9V to run an LED bulb at 9V. Great little device.

These unit work as stated! The are rock stable, and run fairly cool. All in all a very good deal!

Such a good product in such a small package! I had for lithium ion batteries in parallel, and I didn’t have enough voltage, I only had 4 volts and when I wired the chip to the circuit I was able to get over twenty volts easily! GREAT BOARD I HIGHLY RECOMMEND IT! I will be buying again.
