Test with notebook PD charger

There is already exist USB-C vesion of the TP4056 charger, but that chinese board don't support supply form PD chargers.

R1 — can be 0 Ohm, recommend 0.2 Ohm – 0.4 Ohm
R5, R6 is for LED's current limitation, can be used 4.7k-5.1k;
R4 is for set maximum output current, may lower;
RK1 is NTC thermistor for battery temperature control, replace it by 0 Ohm resistor (short it);
