This is the ChargeCard Ultra Slim Emergency Power Bank. It is the world’s slimmest portable charger. This power bank is so slim that it slips effortlessly into my wallet making it easy for me to always stay powered up on the go. It has Integrated USB-C and Micro-USB cables. I was having a hard time getting a charge with the Charge Card Power Bank at first. I was able to get the charging power bank to a full charge, but then the charging bank went from four LED lights to zero before I got a full charge. I would like to know what I’m doing wrong. It gave me 56 percent of a charge. The second time around I got a better charge. I am going to keep playing with it and see how to get it to charge the best. LTKdayinmylife LTKHome LTKTravel
