I used a simple phone-charger power suply that output 5V @1.8Amp. I used a regular Type-A to microUSB cable to connect to the mt3608. I hooked a voltmeter to the output terminals and use the 10-turn potentiometer to dial in my desired voltage (which was 12v). I had good luck dialing in the voltage, with no load attached, when I connected my load, the voltage stayed steady.
I powered a 100mA load and a 200mA load. I left the load on for 12 hours, the unit remained cool to the touch, and stable voltage. I also tried supplying power to the input pins, from a 4.5V battery back. This also powered by 12V load without issue. So far, so good. There are no mounting holes or other mounting accommodations, and the input and output pins have a peculiar spacing of 5.5mm on center. That will make it hard to use with a breadboard. But these tiny, inexpensive, little gizmos appear to work well in my application.

Product Description
- ICstation mini DC-DC voltage booster module supporting DC 2V-24V input and DC 5V-28V adjustable voltage output with high conversion efficiency up to 93%. With on-board micro USB power input port, just connect with the common USB power adapter then you can get 9V/12V/15V/18V/24V output voltage which is ideal for DIY power supply.
- This is a boost converter module, so the output voltage should be at least 2V higher than the input voltage.
- Please turn the potentiometer clockwise by more than 10 turns before the test
- Cannot select the maximum value of voltage and current as of the output at the same time. When the output voltage is increased, the output current is reduced accordingly.
- Input Voltage: DC 2V-24V
- Output Voltage: DC 5V-28V
- Peak Current: 2A (1A is recommended for a long time)
- Max Conversion Efficiency: 93%
- Max Load Power: 7W
- Board Size: 30 X 17 X 14mm/1.18 X 0.67 X 0.55inch(L*W*H)

Functional boost converter, but probably not 2A output current
Paired these with XCSOURCE 10pcs 1A 5V Micro USB TP4056 Lithium Battery Power Charger Board Module TE585 and a solar cell to charge a battery in an outdoor application. The solar cell voltage typically drops down around 3 to 3.5 volts under load, so the boost converter is required to provide a high enough voltage to the batter charging circuit. Tested these using a Lion battery to provide power (approx 3.6V) and set the output to 5V. Everything works - the battery charger provides 1A charging current to the battery as expected. This means a slightly higher than 1A current out of the boost converter. The only unexpected issue was that the output of the boost converter dropped by 0.5V under this load. This puts the boost converter in a low efficiency regime, and it gets quite hot (as in burn your fingers hot). Take the 2A output current rating with a grain of salt - you can probably achieve this for some combination of input/output voltages and currents, but not in the regime I needed to use the circuit. Fortunately, everything still works even with a low input voltage to the charging circuit. You may not be as lucky. If you have a varying load on the output, set the output voltage at the lower end of your load range and check the voltage drop at the high load end to make sure it is acceptable. To test the boost converter, I used a Li-Ion battery (about 3.7 volts) and set the output of the regulator to 5V under no load. I then varied the output current and measured the output voltage. The voltage was pretty constant to about 900 mA, and then started dropping. There is clearly a thermal effect involved - for a fixed output current, the output voltage would drop with time. I measured once increasing the current and once decreasing the current. The second measurement is hotter than the first, and the voltage under the hotter is lower. See the attached plot of the measurements; the blue line shows the increasing (cooler) measurements, while the red line shows the decreasing (hotter) measurements.

*update*
I was contacted by Icstation and they reshipped my order and the boards all arrived in perfect condition and performed as expected. The packaging made all the difference. Im glad that they reached out to me and made things right. Great customer service, thank you
The inductors on the boards are all broken and inside of the static shield bags they come individually wrapped in. The broken pieces are still sealed in the little static bag with the board. So 1 out of 4 came the way they were supposed to. I metered out the 1 broken one I opened and it meters out correctly.

I purchased these based on the mostly good reviews. I had hoped to use them to boost a 3.7 LiPo battery to 5V at less than 500mA.
All 4 defective. Terrible oscillation, large current draw over 100mA
Reviewed in the United States on March 28, 2019
All 4 failed miserably. They were OK at 100mA (see that attached scope trace). The output started oscillating above 100mA and began to draw significant supply current. The other scope trace shows the output at 200mA. In
t only got worse from there.. All 4 units behaved similarly so it is not an isolated component failure.
I tried several input and output Voltages with similar results.
Totally unacceptable for any use and could easily damage your circuit.
