Review on 🌬️ EasyAcc Rechargeable Battery Fan with 2600mAh, Internal and Side Light, 2-8.6 Hours Adjustable Speeds - Portable Handheld Mini USB Fan for Cooling, Traveling, Camping (White) by Heather Welsh

I bought this one because it was a cheaper version of other similar fans from another brand (Opolar, Lileng, EasyAcc, etc.). This particular model came with an LG battery and cost a few dollars. cheaper than others. Works perfectly. Press and hold the power button while the fan is running to turn on the fan light. It took me a while to understand that. The side light can be used when the fan is off. I've used other 18650 batteries in the fan with no problems. I'm using a separate charger, so I can't confirm the charging capability of the fans. It has a circuit that turns the fan off when the battery is getting low (can't remember but I think it was around 3.4v) which is good to keep you from over-discharging. Very happy at the moment.
