5v2a power bank cannot be charged. The rated power of the charging treasure is 10w, so its up and down rated power is about 15W, which can be charged normally within this range, without burning the internal chip of the charging treasure, but for 66w, it far exceeds the rated power range of the charging treasure, and the super power will cause irreversible harm to the mainboard of the charging treasure. Therefore, you can not use 66w to charge the power bank.
No, 66w charger voltage is too high. The 5v2a charger is low voltage. Voltage discrepancy can not be charged
