Review on 🔌 USB Rechargeable LED Reading Light with Clip - Deaunbr Book Lights, Eye Protection 24 LEDs, Flexible Neck Night Bed Lamp, Touch Control Portable Wireless Clamp Desk Lamps for Bed Headboard, Computers by Scott King

I needed a small battery (ie didn't need to be plugged in). This one seemed just right. I charged it overnight before trying to use it the next day. After about 3:00 p.m., 100% of the power was lost. I recharged it overnight, had the same problem. When I went through the return process Revain told me not to return it even though they refunded my money. Found another one today and will write a review on it once it arrives and I've been using it for a day or two, 01/18/2021 Updated review. The lamp is now fully charged and works reasonably well, although one reviewer noted it didn't last 28 hours.
