Woah this is one of the coolest things I've seen today!

• Definitely an eco-friendly and versatile device having multiple functions
• You dont need to worry about your powerbank being empty since it can already be charged through solar power. This is definitely perfect for traveling and even outing geataways
• Can also be used as a bluetooth speaker. Amazing!

Cons:

• I see no cons for this one since this is really a great product! Perhaps the first in the industry. Would definitely want to buy this one
