Question 1

Using 6 of these 5v to 6v for 1.7a mg995 servos. set outs  6. no movement. measured. damn things showed 17 to about 30 and destroyed my servos! why???

Accepted Answer

These boost converters are not current limited, most likely your servos don't draw a consistent amount of current. When electric motors turn on they draw a  huge amount of current(compared to normal operation) sometimes over 8 times as much, called inrush current, this would cause the boost converter to send in a large amount of voltage to compensate. First, never trust the output of the boost converter, always decrease the voltage to minimum and then slowly work your way up untill your motor starts spinning at 6 volts. That will most likely solve your problem. And second, because servos are current sensitive devices it is always better to use a current limiting boost converter with them IF you are putting them under a heavy load. Don't worry, pretty much ever diy'er has burned out electronics before.

Question 2

Can this be used with the 5v dc output from a usb power source to a 20v dc bit of equipment (low power)?

Accepted Answer

Yes, your setup will work. You will have to adjust the output voltage using the blue component with the golden screw on top. Best to measure the output voltage with a multimeter before you connect your equipment.

Question 3

Can this be used safely with an arduino and if so should it be used with the 5V out pin or one of the Analog out?

Accepted Answer

Do not use any arduino pins to power this board. You will fry your arduino. Power the boost converter directly from a dedicated power source and controll the output with a relay.

Question 4

Can i use this to step 12v from a battery to charge a laptop with these specs - output: 15v dc, 3a, 45w?

Accepted Answer

Not if you are using the laptop while charging, this converter is rated only at 30 Watts so find a more powerful converter. I would go with a 100W one with a nice heat sink just for peace of mind.
