1.Mecha transparent design: cool transparent shell, full sense of technology, show the beauty of the internal structure 2. Large capacity support: compatible with 8 21700 batteries, providing long life, to meet the high power demand 3. Fast flash charging technology: support fast charging, high charging efficiency, save waiting time 4. Welding-free installation: modular design, no welding, DIY assembly is simple and convenient. 5. Multiple safety protection: built-in overcharge, overdischarge, short circuit protection, to ensure the use of safe and reliable! Parameter: Output power: 22.5W USB output: 5V/3A, 9V/2A, 12V/1.5A (only 5V for simultaneous output of multiple ports) IN input: 5V/2A Type-C output: 5V/3A, 9V/2A, 12V/1.5A (support PD protocol only output) Type-C input: 5V/3A, 9V/2A, 12V/1.5A Other features: long press to turn on the LED light; installed the reverse does not burn the motherboard (a positive and a negative burn spring) Effective voltage: 3.3V-4.15V (spring has voltage drop) Capacity requirements: the minimum real capacity of the battery pack can not be less than 10,000 mA, otherwise the power did not fall out of the battery has not actually discharged the electricity If the cell phone private protocol is not supported (USB without fast charging), you can use PD charging (TYPE-C output), PD public protocol output is more stable Fast charging specifications (support protocol): Integrated SCP 22.5W super fast charging output protocol Integrated 22.5W flash charging output protocol Integrated QC4.0+/QC4.0/QC3.0/QC2.0 output fast charging protocols Integrated FCP, AFC input/output fast charging protocols Support PPS, PE2.0, SFCP output fast charging Support PD3.0/2.0, PE1.1 input/output protocols Color: Orange Color Materi
