I am extremely satisfied with this Duracell 20,000 mAh Slimmest Power Bank. The build quality feels premium, and despite its high capacity, it is surprisingly slim and easy to carry in a bag. It has become a dependable companion during travel and daily use. The charging performance is excellent, and it provides reliable backup for my devices whenever I need it. The battery backup is impressive, and the power bank itself charges efficiently. I also appreciate the solid construction and the trusted Duracell brand quality. Overall, this product has met my expectations in every aspect. If you are looking for a high-capacity, slim, and reliable power bank from a reputable brand, I would definitely recommend this one. It offers excellent value for money, and I am very happy with my purchase.

The item was great. I was a little disappointed in the cable quality which gave way a few months. The powerbank charged well until it didn't. Thanks to the two year warranty, I was able to replace it in time where the Duracell team, especially Barnali from the team was really helpful in coordinating it. Received the new product quickly. My only disappointment in the product is its charging speed limited to 22.5W power

Although the item was perfectly fine and it performed as per given specifications, but one day after 5-6 months all of a sudden the power bank failed to charge my devices. Lights on the powerbank were coming on but my devices weren't charging. I got in touch with the customer care of Duracell and Ms. Namrata was extremely helpful. It took a week (approx.) but today finally I got a refund of my entire amount paid. Thanks to Duracell Cust. Support Namrata.

I had an excellent experience with the Duracell Support Team regarding my Duracell 20000mAh Power Bank, which had stopped working recently. I had purchased it from Amazon last year, and since the product came with a 2-year warranty, I contacted customer support for assistance. To my surprise, the entire process was handled very professionally and without unnecessary delays. A special thanks to Ms. Barnali Sarkar for her prompt responses, courteous communication, and efficient handling of my case. The issue was resolved smoothly, and I was provided with a full refund under warranty support. Coming to the product itself, the power bank had actually served me very well during its usage period. Its strongest suit was the solid build quality and reliable fast charging performance. The 20000mAh capacity, compact design, and 22.5W QC/PD charging support made it extremely useful for daily use as well as travel. It consistently delivered dependable backup power for my devices and felt like a premium, well-built product in hand. What impressed me the most, however, was that Duracell truly stood behind its warranty commitment even after a year of usage. Good customer support is what builds trust in a brand, and my experience with the Duracell team was genuinely positive. Thank you once again to Ms. Barnali Sarkar and the entire Duracell Support Team for the excellent customer service experience.

⭐ Detailed Product Review: Duracell 20000 mAh Power Bank (Negative Experience) I purchased the **Duracell 20000 mAh Power Bank** with high expectations, given the brand’s long-standing reputation for reliability in batteries. Unfortunately, my experience has been extremely disappointing, and I feel this product turned out to be a complete waste of money. ### ❌ Performance Issues Within just **one month of usage**, the power bank completely stopped charging. Initially, it performed decently, but the failure occurred far too soon for a product in this price range and category. A 20,000 mAh power bank is expected to deliver durable, long-term performance — not fail within weeks. ### 🔧 Poor Build Reliability The early breakdown raises serious concerns about the **product’s quality control and durability**. For a reputed brand like Duracell, this level of unreliability is surprising and unacceptable. ### 📞 Worst After-Sales Support The most frustrating part of this experience was the complete lack of support: * **Amazon Service Center**: No resolution provided despite raising the complaint. * **Duracell Support Center**: Equally unhelpful — no proper guidance, replacement, or repair solution offered. Instead of assistance, I was left running between both parties with no ownership from either side. This clearly reflects a **failure in customer support systems**. ### 💸 Value for Money Considering the early failure and lack of support, this product offers **zero value for money**. Spending on a branded product should give confidence and peace of mind — not regret. ### ⚠️ Final Verdict * Product Lifespan: ⭐☆☆☆☆ (Very poor) * Reliability: ⭐☆☆☆☆ * Customer Support: ⭐☆☆☆☆ * Value for Money: ⭐☆☆☆☆ 👉 **Overall Rating: 1/5** ### 📢 Conclusion This purchase has been a **complete waste of money and time**. The product failed quickly, and both Amazon and Duracell customer care were unable (or unwilling) to help. **RIP Duracell — not the quality I expected from such a big name.** *** If you’re considering buying this power bank, I strongly recommend looking at alternative brands with better reliability and customer service.

Main is power bank ko kareeb 1 saal se use kar raha hoon aur performance abhi bhi bahut achhi hai. Ek baar full charge karne par mera mobile 3-4 baar aasani se charge ho jata hai. Charging speed bhi achhi hai aur battery backup expected capacity ke kaafi kareeb lagta hai. Build quality premium hai aur carry karne mein bhi convenient hai. Long trips aur daily use dono ke liye bahut reliable product hai. Ab tak koi issue nahi aaya. Overall, paisa vasool aur highly recommended power bank. 🔋⚡👍

This power bank is very good, and its overall quality is satisfactory. However, after about one year of use, it suddenly stopped working. I registered a complaint through Duracell Customer Care, and I received a replacement within a few days. The customer service was prompt and efficient. Apart from the unexpected failure, I was satisfied with the quality and performance of the power bank.

⭐⭐⭐⭐⭐ 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!
