What are the best high-capacity power banks with over 50000 mAh battery?

Any mobile power bank that claims to offer more than 15000 mAh is most likely a fake. You must be very careful when you buy a power bank because there are so many fakes in the market place. The most basic tip I can offer you right now is weight. The higher the capacity, the heavier it should be. Imagine the weight of a car battery compared to a pocket power bank. Also compare the wight of a small car battery (about 30 Ah) to that of a heavy goods vehicle (circa 75 Ah). You’ll find that the second one is much heavier because of the larger capacity hence more power on offer.

But you have to be extra careful with portable power banks. Like I noted above, there are too many fakes in the market and many of them are filled with sand bags. But there are other checks you can do to avoid these fakes. Have a look at Solar Power Bank Quality Assurance | HetoGrow Power Bank
