Battery And Cell Charger

USB Current Voltage Meter Battery Tester measures and displays current and voltage simultaneously. USB Current Voltage Meter Battery Tester is also known as USB Doctor. This can easily measure the operating current of the output voltage of the USB port and equipment 2. This current power meter is a small size, no power, and other ancillary equipment, plug and play also detect USB charger output voltage and current are standardly suitable for charger testing, USB current tester, another measurement of USB voltage and currents.

This 3.7V Battery Charger TP4056 module is made for charging rechargeable lithium batteries using the constant-current/constant-voltage (CC/CV) charging method. In addition to safely charging a lithium battery, TP4056 BMS Board also provides the necessary protection required by lithium batteries.

This TP4056 1A Li-Ion Battery Charging Board Type C with Current Protection is a tiny module, perfect for charging single cell 3.7V 1 Ah or higher lithium-ion (Li-Ion) cells such as 16550s that don’t have their own protection circuit. Based on the TP4056 charger IC and DW01 battery protection IC this module will offer 1A charge current then cut off when finished.
