Q: Just to confirm this is both a lipo charger and 5v boost converter, correct? when you remove the usb power, the battery will be boosted to output 5v?

Yes, this device is both a lipo charger and 5v boost converter. A few things I determined about its operation are: 1. When disconnecting the (micro) USB power the 5 Volt output power (at the Type A USB port )will drop to zero volts for about 200 to 300 msec and then switch to the boosted 5 volt output. 2. There also has to be a minimum output load for the output to be boosted. It was boosted when I had a 1 Kohm load, but it was not boosted when I had just had the meter (~10 Megohm) on the output. Then I just got the battery voltage. 3. The boosted output also seemed to have problems when supplying an output current near 1 amp. I believe that is is only rated for 1 ampere output current.

Q: My board charges my phone for 10 seconds, then get really hot and turns off and stops charging. Battery: 3.7v 16340 li-ion. Short circuiting? Help?

If your phone is a fairly new model my best guess is that board cannot supply enough current. The board I tested would only supply about 0.7 Amps.

Q: Why does the output only read 3.9V? I have 4V input.

When you say you have a 3.9V input, I'm assuming you mean you have a battery connected. If you have a charged lithium ion battery connected with the plus terminal to B+ and the minus terminal connected to B-, you should see 5 volts output on the large usb connector. Some of these modules (not sure about this one) require a minimum load to be connected to the large usb connector before the full 5 volts is output. Try plugging in a phone and then check the voltage. It's also possible that you've got a bad module. In that case, try another one.

Q: can i connect a solar cell directly to this to continuously power an esp01 charging in day and running on on battery at night?

You'll need a Diode to block reverse current to the Solar panel. Would not recommend it though as there will most likely be too much losses in the conversation and solar panel most likely will not put out enough current. But in theory it would work.
