Is there any warning about the powerbank requiring high discharge cells to safely handle the high current draw from the boost converter? If there's really a 66W output that's nearly 10A per cell.
i had 2 INR21700-40T from a project left and wanted to Build this Powerbank... it seems taht the Charging Curcuit only recognizes 2500 mah cells... anybody else with this problem_?
I think Hoco came after these appeared out of blue one day in the AliExpress. Who came first? Who knows? There were a few models with different configurations such as numbers of the batteries. But soon after they popped up, now they are not seen so much these days. It’s a kind of mystery product from deep underground Shenzhen China ha ha.
Well those are some obviously BS cells. 6000mAh? They surpassed Samsung, LG, Sony, Panasonic, Molicel, Lishen, EVE, and BAK! The Samsung 50S is already irrelevant!
