Specificatii
The TP4056 is a complete single-cell Li-Ion battery with a constant
current/constant voltage linear charger. The SOP40 package with
heatsink on the bottom of the TP4056 and fewer external components
make the TP4056 ideal for portable applications. The TP4056 is
suitable for USB power and adapter power supplies.
Due to the internal PMOSFET architecture and anti-reverse charging
path, no external isolation diodes are required.
Thermal feedback automatically adjusts the charge current to limit
chip temperature during high power operation or high ambient
temperature conditions. The charging voltage is fixed at 4.2V, and
the charging current can be externally set by a resistor. When the
charging current drops to the set value of 1/10 after reaching the
final float voltage, the TP4056 will automatically terminate the
charging cycle. When the input voltage (AC adapter or USB power) is
removed, the TP4056 automatically enters a low current state,
reducing the battery leakage current to less than 2uA. The TP4056
can also be placed in shutdown mode when there is a power supply,
reducing the supply current to 55uA.
Other features of the TP4056 include battery temperature sensing,
undervoltage lockout, automatic recharge, LED status pins for
charging and termination.

Protection About Type-c usb module and micro usb type-1 module :
The battery overcharge protection voltage: 4.28 V
Battery overcharge lifting voltage: 4.00 V
The battery discharge protection voltage: 3.0 V
Battery discharge termination voltage: 3.2 V
Battery: over-current protection current 3 a
NOTE:
1. Ampere meter can only be connected to 5v input end of the
module.
2. It is better that the charging current is 37% of the battery
capacity. If you charge to the battery of 1000mAH, current of 400
is enough.
3. The connection wire should not be too thick.
4. Make sure the connect point is good.
5. If the input voltage is too high, like 5.2v, the current will be
less than 1000mA, it is normal. It is protection function,
auto-substract the charging current to avoid burn damage to
chip.
6. NO Reveral polarity.
