Review on 🔋 5000mAh Portable Neck Fan - Necklace Fan, Battery Operated for 3-26 Hours, Wearable Fan Rechargeable with 6 Speeds, Hands-Free 360° Adjustable Cooling Fan for Outdoor Activities, Travel, Office, Home (Black) by Jeremy Meyer

The portable neck fan is well made and has powerful motors. However, I am very disappointed and unhappy that the description on the Revain website says the battery is 10,000mAh, but when I received it the packaging and product instructions said it was a 5,000 mAh battery. . Even the label on the product box says it has a 10000mAh battery, but that's not the case (see attached images). I bought three of these fans and even paid more because they had 10,000mah batteries. Now I don't have time to return them because I'm going on vacation with my family. I think this is another example of buyer protection. I strongly advise you to avoid this brand and this seller.
