Great product! It can charge my 5000mAh phone 4-5 times. It weighs 565g, so it's not exactly lightweight.

This power bank is incredibly powerful and delivers on its promises. I haven't weighed it, but it's quite heavy, which indicates that it contains batteries capable of storing and delivering a lot of power. With the right charging cable, you can immediately see how quickly my phone charges. I highly recommend this power bank; it seems to actually deliver the performance parameters it advertises. Fast delivery and very good quality—I wholeheartedly recommend it.
J
The bag and the box were a bit wet, but the power bank itself was dry and undamaged. I hope it stays that way. Otherwise, it charges my phone quickly and doesn't lose any battery itself. I'm satisfied so far
b
It's a bit heavy, but it charges super fast. I highly recommend it.
N
I'm very happy with the fast delivery and with the item itself
j
I bought this power bank for its output power so I could run LED lights, which doesn't work with weaker power banks. It does exactly what I need it to do. So, five stars from me!
b
Wow, for this price, you really can't ask for more... so many charging options, and not just one! It's too big for a pocket, but perfect for a backpack.
