Power Bank Xiaomi Redmi Fast Charge Power Bank 20000 mAh (PB200LZM) Black. Reason for sale — I bought it to charge the quadcopter's batteries. The quadcopter is no longer around, and I don't need such a capacious power bank for charging my phone. I bought it at Zoommer store, the receipt did not survive. Now such a power bank costs about 90 lari, I am selling it for 50 lari.
