Duracell Powerbank 20000mh with Series 3 - A to Lightning Cable

Thanks for the response and the immediate replacement of productThe new power bank is performing well

Slimmest Powerbank , it is actually slimmest in 20000mah , quality of the product is really good .Everyone just go for it

I bought this Duracell 20000mAh power bank and it has completely failed. Not only does it not charge or provide any backup, but the power bank has also swollen up dangerously, turning into a serious fire hazard.This is not just product failure — it’s a safety threat. It could have easily caught fire or caused harm. I contacted Duracell’s customer service over 15 days ago, and despite the product still being under warranty, I have received no help or resolution from their side. Absolutely ridiculous service for a company of this reputation.To make it worse, Amazon has also refused to help, washing their hands off the issue completely.Stay away from this product. It's unreliable, dangerous, and backed by pathetic customer service. Highly disappointed.

Very useful while travelling. Charging speed is good and give more backup.

Very nice product, easy to use

Duracell power bank good work

Excellent product 👍
