Hi, @xplore, Nice Hunt
Below is my opinion about your product.
Pros:
- The product is incredibly lightweight meaning it is easy to transport.
- The water that can be used to charge doesn't have to be clean or distilled.
- Each fuel cell retains a charge of up to 100 hours per dip thats cool.
- A USB port can be used to charge up mobile phones and other equipment.
Cons:
- The cells can only be recharged three times and then they must be replaced.
