Can I use a 14.4 volt 5A power supply?

Yes, up to 16 volts. Less than one ampere, key down on CW.

What is max DC voltage this can take? I just bought this on Amazon. I already have a 14.4 volt AC/DC power supply for my X6100. Will it work?

I have read it will work up to 16 volts. Works at 14.7volts, making 5 watts.

What is included with this transceiver? What comes in the box when it’s delivered?

Assembled one with 3D printed case (orange)，Plug and play. Include: one unit of assembled rig and one unit DC.

Can you use a 3s battery with this?

3S li ion battery pack can be used with this Qrp rig. There are two ways of powering. The first is a usb connection for 5 volts and I believe 1/2 watt out. The second is to use a tubular dc power connector which is supplied with the unit. If you use 12 volts the specs say you will get somewhere near 5watts but I’ve heard rumors in some units it’s a little less wattage. The 3d printed battery boxes that slide on the back of the radio are for 3 18650,s nominal 3.7 v to 4.2 volts max each in series for 11.1 to 12.6 volts. I personally bought a 3S power brick rather then a 3S shrink wrapped type brick.
