Its an excellent product, I have been using it since 2 years, Its fast charging capacity, battery backup and size are really good. Their customer service is also very professional and fast, they replaced my power bank at the end of its warranty period. Over all a good product and worth the money.

Good charger but many times shuts off by itself even at low battery , like 30-40 %. Messes up with the charging cycles !

Had this power bank for 1 1/2+ years and it performed well. Fast charging, good looks & finishing, battery life as promised (able to charge 5000 mAh mobile 3 times fully and close to 80% 4th time. Comes with high quality USB A to USB C cable, some may think the length is small but to me it was plus point, no tangling. Now coming to equally important aspect besides quality when we buy such product - this power bank comes with 2 years warranty and more importantly, their customer support team at UCL India is great and responsive. After 1 1/2+ years of usage, I noticed my power bank had swelling at the center. I immediately contacted their customer support and their specialist (Bhumika) promptly guided me through procedure to request replacement. Had to share video of the power bank and invoice and serial number, after approval from their side, within a week I received replacement device. There were timely follow-ups from their side and they even arranged for pickup of swelled power bank. Last 2 months or so, the new power bank is working fine without issue. I went for this power bank in hope to get good product and good service, I got both, so happy.

⭐⭐⭐⭐⭐ The Trusted Bunny Delivers! A Truly Reliable Powerhouse. Reviewed in India on 13 September 2025 Size: 10,000mAh | Color: Black/Copper | Verified Purchase ✓ I've been through so many power banks from unknown brands that promise the world but fail within a few months. I finally decided to spend a little extra on a brand I trust, and I'm so glad I did. This Duracell power bank is fantastic. What I Love: Built to Last: The first thing you'll notice is the build quality. It feels incredibly solid and durable, not like a cheap piece of plastic. The iconic black and copper design is a nice touch. Honest Capacity: This is a true 10,000mAh power bank. I can get about 2.5 full charges for my Samsung Galaxy S24, which is exactly what I was hoping for. It holds its charge for weeks when not in use. Decent Charging Speed: It's not the absolute fastest on the market, but the USB-C port charges my phone quickly and safely. I get from 20% to 80% in just under an hour. Peace of Mind: With a brand like Duracell, I'm confident that it has all the necessary safety features to protect my expensive phone from overcharging or short-circuiting. That peace of mind is worth the price alone. Clear Indicators: The 4-LED light system to show remaining power is simple and effective. Any Downsides? Honestly, not really. It has a bit of weight to it, but that's expected for a quality 10,000mAh unit and only adds to the sturdy feel. Final Verdict: If you're tired of unreliable power banks and want something that just works, every single time, this is the one to get. It’s the perfect companion for daily commutes, travel, and power cuts. Highly recommended!

Good service. The item I ordered through Amazon was working perfectly at first. After three months it stopped working properly, so I claimed the warranty. The technical support team was very cooperative and supportive, and my issue was resolved very quickly. I received a replacement, and the power bank is now working perfectly. The technician, Boomika, was very supportive and helpful throughout the process.

I am very happy with my Duracell power bank. The build quality is solid and it charges fast. What impressed me the most is their service. I had an issue within warranty and got a smooth replacement without any hassle. Excellent product and excellent after-sales support. Highly recommended!

The product has not lived up to its standards until now. (its been just about 2 months since i brought this from Amazon) Repeatedly failed twice in a month after purchase. But Duracell warranty and after sales service is excellent. Got the replacement on both times without any issue. The Customer Care executive of Duracell is very helpful in this matter.
