1. Large capacity support: compatible with 8 18650 batteries, providing long life, to meet the high power demand 2. Fast flash charging technology: support fast charging PD45W+ Super Flash Charge 40W + Super Fast Charge 35W + Flash Charge 30W + Fast Charge 25W + Standard Charge 15W, high charging efficiency. 3. Welding-free installation: modular design, no welding, DIY assembly is simple and convenient. 4. Multiple safety protection: built-in overcharge, overdischarge, short circuit protection, to ensure the use of safe and reliable! Note:The battery level will be inaccurate when the battery is first inserted. The battery pack must be fully charged and discharged from 0-100% for at least three cycles to be accurate. Output Power: 45W (48W Peak) Input Power: 30-65W (requires a high-performance charger and charging cable) USB Output and Supported Mobile Protocols: 5V/3.1A (standard output); SCP: 40W; UFCS: 33W; SVOOC: 45W; VOOC4.0: 30W (requires a high-performance flash charging cable); VOOC1.0: 20W (requires a flash charging cable); PE1.1: 7.5W; PE2.0: 30W; QC3+: 45W; QC3.0: 36W; QC2.0: 24W; AFC: 18W; FCP: 18W; SFCP: 18W; Multiple ports simultaneously output only 5V. Type-C output and supported mobile phone protocols: 5V/3.1A (normal output); PD3.1: 45W; PPS: 44W; SCP: 40W; UFCS: 33W; SVOOC: 45W; VOOC4.0: 30W (requires a high-performance flash charging cable); VOOC1.0: 20W (requires a flash charging cable). PE1.1: 7.5W; PE2.0: 30W; QC3+: 45W; QC3.0: 36W; QC2.0: 24W; AFC: 18W; FCP: 18W; SFCP: 18W; Multiple-port output without fast charging; Note: If your phone's proprietary protocol is not supported (USB fast charging is not available), you can use PD charging (Type-C output). The public PD protocol provides more stable output and higher output power.
