Heavy one and huger, than i expected. Came 25%-50% initially charged, Xiaomi product code passed Product Authentication at the Xiaomi site. Checking the current and voltage while charging the bank with the fast charger I've got about 10W, not 18, but it can be maximum capability of my charger. I recommend product and seller, Item came almost instantly, just four days after payment, Item looks really great, brand new, firmly packed and just perfect. If you need one - definatelly you can buy with no worries.
Works fine. It’s kinda heavy though. I appreciate the inclusion of both type c and micro-usb intake ports. Takes a lot of time to charge without fast changing.
