Complete linear charger for single cell lithium-ion batteries in SOP-8 package. Programmable charge current up to 1000mA with external resistor. Fixed 4.2V charge voltage with 1.5% float voltage. No blocking diode required due to internal PMOSFET architecture. Thermal feedback regulates charge current during high power operation
QC is Qualcomm's proprietary fast charging technology for mobile devices. It manages power delivery through USB communication and voltage negotiation. QC enables charging at higher power levels than standard USB
Quick Charge is Qualcomm's proprietary USB battery charging protocol. Charges devices faster than standard USB by increasing output voltage. Requires both device and charger support for operation. Uses existing USB cables with voltage negotiation capabilities
Programmable charge current up to 800mA with 4.2V output voltage. No external MOSFET or blocking diode required. Constant current/voltage operation with thermal regulation. Charges single cell Li-Ion batteries directly from USB port
TP4056 is a 1A linear Li-Lon battery charger with thermal regulation. Input voltage ranges from 4.5V to 5.5V, maximum charge voltage is 4.2V. Charging current is adjustable from 1A to 10A. Compatible with 18650 cells and other 3.7V batteries
Power banks have 4 LED lights that turn off when battery is low. Wait until only 1-2 lights are on before charging. Most power banks charge within 1-2 hours
