This Eco Flow River battery capacity is 77,830 mAh or 77.83 Ah But the mAh number is just for your comparision with other power banks. mAh only tells you about how much current it gives and for how long, but at what voltage ? Typically, all power banks are at 3.7 Volts. So, mAh measurement works. Correct units of any battery capacity is Wh (this battery is 288Wh). For your comparision, capacities of various power banks are... 10000mAh means 37 Wh, 20000mAh means 74 Wh, 27000mAh means 100Wh (Battery capacities in Wh are written at the bottom of power banks, if you want to check) Your video helped me a lot. Hope my comment hepled you too.
