VOKTTA | 3-5S PD 100W DIY Power Bank Mainboard with TFT Screen Bidirectional Fast Charging MPPT Solar Compatible Battery Protection Board

Features1. Supports full 100W power for both input and output, compatible with 3-5S lithium-ion batteries and voltages ranging from 3.6V to 4.5V, offering broad applicability.2. Built-in MPPT (Maximum Power Point Tracking) functionality allows connection to solar panels for efficient utilization of solar energy.3. Utilizes automatic step-up/step-down technology with intelligent switching between PWM and PSM modes to balance efficiency and power consumption.4. Integrates a full suite of protection mechanisms—including overcurrent, overvoltage, short circuit, over-temperature, and under-temperature protection—to ensure safe operation of both the device and the battery.5. Offers nearly 30 adjustable menu parameters to meet the needs of advanced enthusiasts and professional users for fine-tuned settings.6. No need for a voltage simulator; directly outputs adjustable voltages from 3.3 to 21V. USB port output voltage, current, and power can be configured, making it a versatile all-in-one solution.Input/Output Fast Charging ProtocolsType-A1 and Type-A2 supportUFCS/PE1.1/PE2.0/QC3+/QC3.0/QC2.0/AFC/FCP/SCP/SFCPOutput ProtocolsType-C1 and Type-C2 support PD3.1/UFCS/AFC/FCP/SCP input protocolsType-C1 and Type-C2 support PPS/PD 3.1/UFCS/PE 1.1/PE 2.0/QC 3+/QC 3.0/QC 2.0/AFC/FCP/SCP/SFCP output protocols; Micro-B supports UFCS/AFC/FCP/SCP input protocolsIP supports PD 3.1 input protocolVoltage, Current, and PowerPPS/PD 3.1: 20V @ 5A, 3.3V–21V @ 5A, Max In 100W / Max Out 60WUFCS: 3.4–21V @ 5A, Max In 100W / Max Out 60WQC 2.0: 5V 3A / 9V 3A / 12V 2.8A / 20V 1.5AQC 3.0: 3.6V–20V @ 200mV/step! 5V @ 3A / 9V @ 3A/12V@2.8A/20V @ 1.5AQC3+: 3.6V–20V @ 20mV/step! 5V @ 3A / 9V @ 3A/12V@2.8A/20V @ 1.5AAFC: 5V 3A / 9V 3A / 12V 2.8AFCP: 5V 3A / 9V 3A / 12V 2.8ASCP: OUT 3.3V–12V, IN 5V/9V/10V/12V, supports 10V 4APE1.1: 5V/7V/9V/12VPE2.0: 5V–12V @ 500mV/stepSFCP: 5V/9V/12VVOOC: Supports VOOC 5V, 1.0 10V 5A, and 2.0 10V 6.5AThe mainboard must be connected to the battery exactly as shown in the diagram. If the battery has its own protection board, simply connect the battery’s positive and negative terminals to the B+ and C- pads on the mainboard. Otherwise, if the mainboard has built-in protection, you must follow the diagram exactly and connect the balancing wire; failure to do so will prevent normal activation and use!!!Package includePower Bank Module *1Balancing Wire *1
