Good thing! The voltage is adjustable from 4 to 27. On one li-ion, you can make uninterrupted power for a variety of low-power consumers.

Tuned to 5 volts. The most interesting is to check the low voltage cut-off on the battery. They write that no. If not, it’s very bad. Although the chip is the same as on the regulators with the compartment. There are sites for soldering, i think it can be possible to solder that to turn on the cut-off on low voltage.

Used by self-made 9V battery that can be charged. Since it can be boosted to 9 V in combination with the Lipo battery, you can make your own non-disposable battery.
