1. High-capacity support: compatible with 8 18650 batteries, providing long battery life, to meet the demand for high power 2. DC regulatable function: support the output voltage adjustment, adaptable to a variety of devices, flexible and practical 3. Welding-free installation: modular design, no welding, DIY assembly is simple and convenient. 4. Multiple safety protection: built-in over-charging, over-discharging, short-circuit protection, to the use of safe and reliable! Output power: 22.5W USB output: 5V/3A,9V/2A,12V/1.5A (only 5V for multiple outputs at the same time) DC (5.5 x 2.1) output: 5V/6V/7V/8V/9V/10/11V/12V (3A-1.5A) 18W IN input: 5V/3A, 9V2AType-C output: 5V/3A, 9V/2A, 12V/1.5A (support PD protocol only output) Type-C input: 5V/3A, 9V/2A, 12V/1.5A Features: single-click to display power, double-click to turn on outdoor LED color light, long- to switch DC mode/USB mode; output input real-time current and voltage display Effective voltage: 3.3V-4.15V (spring with voltage drop) Capacity requirements: the minimum real capacity of the battery pack can not be less than 10,000 mA, otherwise the power 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 , PE2.0, SFCP output fast charging Support PD3.0/2.0, PE1.1 input/output protocols Color: Black Material: plastic Package Contents: 1 x battery box (Batteries not included) Only the above package content, other products are not included.
