From the reviews I read, there are some major advantages that other power bank does not have.

• 3 - 4 filling process simultaneously. IP65 has incredibly effective advantages, however, 3 to 4 charging simultaneously requires considerable power. Without device stability, the possibility of short-circuiting damage may occur at any time.
• USD Support and Wireless Charging. You could say this product is very complete, has a USB charging type, and also Wireless, making this product multipurpose.
• Solar Charging. IP65 is very environmentally friendly and cost-effective because it converts solar thermal energy into electricity.
