1. Our company's original research and development of the portable power bank breaks away from the traditional exterior design and innovatively adopts a transparent exterior design. You can see the electronic components and battery inside, which is full of technology. The digital display screen can show the real-time power voltage, output, input, and battery situation. It is highly practical, adopting vehicle-standard battery cells with a conversion rate of up to 80%, supporting 22.5W PD fast charging, and featuring a multi-plug design with three outputs and two inputs. It is highly practical for outdoor and home use and can also be used as a beautiful decoration. The research and development cost is high, and previously, in order to promote it better, our profit was very low. 2. We offer better prices for larger orders and higher quality products.
