10000 mAh Fast Charging Power Bank Cum Handwarmer with LED Display for iPhone, Samsung, One Plus and All Smartphones.

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!

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

After using a couple of products, I think this is the best power bank I have used, charges my iPhone really fast. This once charged, stays for a long time and because I travel a lot, I do not worry now about my drained mobile battery. I even use it to charge my hotspot. A great purchase.The above one was when I initially purchased it ans adter 8 months even with full charge its charging a phone just once. Its's sad because my other power bank with much less capacity is running for 7 years. When you purchase a product you don't expect it to run for just few months. It's not about the money but the product experience. Plus it is not working. Contacted Amazon and they have not been helpful. Would not recommend you to buy the product.It was still within warranty period and I contacted Coolnut, they asked me to send the product and they would repair it. They repaired it and had sent it but I sadly, they have changed the case to a worn out case. If it's in warranty I don't know where in the world, you replace the product with an old product. WOULD NOT RECOMMEND IT. I have escalated it to Amazon, hope they will help.

The media could not be loaded.  Worst Product . I swear this is my first comment on Amazon just because i got worst product ever from Amazon . It stopped working after using four or five times . Who is its owner ? I really want to raise complaint to consumer court ? Such a worst worst worst brand ! Dude please don’t buy ! Please..! Rest your wish .I still have the warranty card . Exchange it or give my money back ..!Exchange my product you fraudssss . One star isliye dena pada because one star diye bina comment add nahi ho raha ! Otherwise one star bhi nahi du .

This puts out enough output to quickly charge my Samsung S7 (feels the same as plugging it into the wall). I like that it has multiple outlets to charge multiple devices simultaneously. I've had it for about 4 months now and it still works well. Mine goes down to 75% after one charge, so I don't know how many charges it would really give. I wish that the display gave an actual percentage vs. a range. Of course, it's not going to be at 100% after fully charging a phone, but is it really already down to 75%? Still some room for improving the product, but overall I'd recommend it for the low price compared to products from the US.

The plastic case is brittle and flimsy and is not classy in looks. In a few months it stopped working and when I contacted the sellers, they want me to send the battery to their address. With the additional work of packing / sending it over courier spending my money, I kept it aside. In another few months, the entire case depleted and the circuit board and the inside chemical cell in silver foil...all are exposed. I will throw it now!

Threre is no doubt that this is a really good product, above average. This is my third powerbank, I ordered MI 20000 mah powerbank as well some time back. The only reason I bough this one because of the battery display LED, cool looks and since I already had MI one wanted to try this one.1. I've been using this since 3 months now. I charge my Samsung A50 which is 4000mah around 4 times(4th time upto 75%).2. This powerbank takes around 8 hrs to get fully charged.3. Size wise it is a bit heavier and bigger than expected.4. The only flaw I found apart from size and weight is the finishing of the product is not very good. I can see the led lights where two sections are joining which is very annoying, kind of gives a cheap look to it.
