5.0 out of 5 stars Great for the price
By James Whiteman on 11 April 2019
Bought this power bank a month ago and it is performing perfectly. Capacity tested and it charged to just over 30,000mah or around 19,000 if fast charging due to it being at 9v not 5v.

The only disappointing thing is the max 18w output as for a power bank of this size, using all 3 output ports it won't charge all devices at full power. Would be much better if it could do 25w output.

But for the $40 I paid it was well worth it.

3.0 out of 5 stars Received a Used power bank
By JS on 19 July 2020
I ordered the 30000mAH one during a promotion; the price was good. However, the power bank that I received had a number of visible scuffs on its body and USB ports. It looked like it was a USED item re-packaged, which was disappointing specially when the item is listed as New.

Having mentioned this, the performance of the item is okay. Although it is a bit on the bulkier and heavier end for the purpose of portability, the bank carries a reasonable amount of charge as it should.

Am I happy with the power bank, all things considered? Meh.
Would I purchase this again? Probably not.
Would I send this to someone as a gift? No way.
