Thumb Score: -1
$ 27.89 with prime +20% coupon and get 2 for the price of 1. My total is $ 22.31 for 2 before tax. Fan seems fragile according to review but I’m going to try it because it’s cheap.
This item also part of the 2 for 1 promotion, but I didn’t order this because this solar panel is smaller https://www.amazon.com/dp/B09PYZ1…I6I13
I need a small solar fan for my window greenhouse hopefully it can move some air. Never own any solar panel before, may I ask if I want to charge my phone or power bank with this tiny panel, do I need to get a controller? Just for emergency. Thank you.
