Review on Taurusb Handheld Rechargeable Ventilador Multi Function Heating, Cooling & Air Quality by Tina Zeiher

I was going to give it an A but the fan cooled well and I liked that it was small and easy to carry. BUT. I brought it with me thinking it might be a portable charger and when I tried it my phone was ONLY 1% charged for every 10% battery drain of the product. My phone started at 11% and I was using the wearable when it was at 68% and when the wearable turns off (battery dead) my phone only charges up to 19%. Very quiet.
