😱 ৬ ঘণ্টা চলবে এই Fan! সত্যি নাকি মিথ্যা?

😱 This Fan will run for 6 hours! True or false? #rechargablefan #fan #bdnews In this video, I have shown how I made a Rechargeable Fan that consumes only 0.8 Amp current and can provide backup for about 6 hours 😱 I have used 6 Lithium Battery Cells of 2000mAh here, which together have a total capacity of about 12000mAh. Due to this powerful battery setup, the fan can run for a long time, which is very useful during loadshedding. ⚙️ This fan uses RS555 Copper Motor, which is much more efficient than a normal motor. Where a normal motor takes a current of about 2 Amp, this motor uses only 0.8 Amp. 🔋 As a result, the total power consumption is about 9.5W – 10W, which makes it a low power but high performance fan. 🔌 Also, a high quality Trickle Charging BMS has been used here, which keeps the battery safe and provides protection from overcharge, over-discharge. This makes the battery life much longer.
