One year warranty is fake. Amazon isnot helping either. *by S***U on Reviewed in India on 4 August 2018* Would not recommend it at all. 3 times the cost and has stopped working after a month of buying. A terrible power bank. It stopped working on exactly the 32nd day, its like they planned it. Thugs! ### ⭐⭐⭐⭐ Coolnut awesome *by A***R on Reviewed in India on 12 September 2018* Bought this one around 2 weeks back. Used it for few times till the powerbank was empty. So the review is based on that.If you want something at sub 2k, go for it. Best value for money. But with higher budget you can get better power banks in terms of long lasting battery and better build quality. For more details go through the review below.Overall 4/5Printed battery capacity 5/5Actual battery capacity 3/5Design and build quality 4/5Ease of use 5/5Value for money 5/5Patriotism 5/51) Printed battery capacity is 20,000 mah. Getting such high capacity at such low price. My sony 10,000 mah power bank was of 2.5 k around 2 yrs back. 5/52) Real life battery capacity is probably 12,000-14,500 considering I could charge my S7 only 4 times (it has 3,000 mah battery). Whereas my sony 10,000mah powerbank can charge S7 ,2.6 times i.e. almost 8,000 mah and it is a 2 years old one. Only time can tell how long Coolnut can last. 3/53) Build material and design seems ok. Sony Power bank has better build quality. 4/54) 2 charging port, fast charging, led indicator and small led torch. Awesome. Far better than my sony power bank. 5/55) So in effect I get around 13,000 mah power bank at INR 1,700. Far better than 8,000 mah sony power bank at INR 2,500. 5/56)And this one is made in India. Cool. 5/5 ### ⭐⭐⭐⭐ VFM product *by S***L on Reviewed in India on 28 March 2018* Pros :2 days backup for 2 phonesgood VFMgood build qualitysoft touch body - non slipperyconsLED torch bit dimBattery capacity indicator is NOT screen (as seen in image) but simply numbers backlight by individual LEDs --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/64653737-10000-mah-fast-charging-power-bank-cum-handwarmer-with-led](https://www.desertcart.tn/products/64653737-10000-mah-fast-charging-power-bank-cum-handwarmer-with-led) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-11*
