HiLetgo 5pcs DC-DC Buck Step Down Module 6-20V 12V/20V to 5V 3A USB Charger Module

Q: Hello! i need to use them with input 28vdc, will this voltage damage the unit? thanks!

Anything over 20V will cause these units to shutdown. The original listing (when I bought them) said they had a range up to 24VDC input. None of them worked for me trying to use a 24VDC power supply. I have since come back to rate them and see that they have changed the description to indicate the max input voltage is 20VDC. I wasted my money on them.

Q: Which is positive input and which is negative?

Look closely, the ground is attached to ground plane. The positive input is isolated from the ground plane. It should be obvious.

Q: I wanted to solder four 18650 flat top batteries to this. Can i recharge those batteries with this board after they are drained from charging phone?

No, this board only works in one direction (high voltage -> 5V). You need a Li-Ion/LiPo charger board for recharging 18650 cells. E.g. https://www.amazon.com/Makerfocus-Charging-Lithium-Battery-Protection/dp/B071RG4YWM

Q: How do i charge samsung galaxy a7 pad with this board? i use large solar panels dc. i don't use ac. i don't need to charge battery. the opposite way.

The ac adapter’s turn ac into dc the battery in the phone is DC Just about everything that plugs in the AC converts it to DC for its internal workings televisions radios phones etc. USBs normally put out 5 V DC and 12 V DC you need to find out what your phone uses set the board to that DC voltage level and plug in your USB cable to your phone That’s basically the short and sweet for the actual hook up and all that information you’re gonna have to look on some stuff on the Internet
