The first test was to find out the true magnification. No, somewhere around 1300X. My test with a 0.015 wide pencil line was only 200x at full magnification. I emailed the company to ask if my device is just bad. Still waiting for an answer. The included battery was now fully charged, so I could use it without plugging in the USB cable for power. The device could not be switched on. The battery was checked with a tester with a load. After a day of charging on the block, the battery only had 3.5 volts. I took one of my fully charged batteries and it didn't work either. Should I assume the monitor requires a full 5VDC to turn on? That's all collected for return.
