I bought Lontor rechargeable fan from JUMIA yesterday. I assembled it and since the instruction says charge 20 hours first before use i obliged. But while the charging was ongoing i tried to switch on the fan to see if it was working. Alas, nothing happened! LED was working. All other functions, but the blades refuse to roll.

What might be the problem? must i charge it fully before it works? Isnt it suppose to come with atleast some energy stored so one can check if it works?

Any suggestions?

How do i contact JUMIA? That's why i asked the delivery man to get someone to assemble it but he told me its not how it is done.
