Coolnut 20000 mAh QC (Quick Charge 3.0) Fast Charging Power Bank with 18W for iPhone, Samsung, One Plus and all SmartPhones (With C-Type Cable)

Writing a review with just a couple of days of Usage feels unfair, hence writing it after thorough usage of this very good quality device after 2 weeks of rigorous usage on a trip. Big thing is that this is a "Made In India" product and has the Fine Quality of a Swiss made Watch.Pros: Build quality is good (can be better),Battery charging is good for a 20k mah capacity battery (10hrs charge required for this to charge from 0 to 100) i plugged it into a QuickCharge Anker charger (but it will NOT quick charge hence took 10hrs from 0..to..100),Charge on this device remains stored for a longer time with very minimal drainage (powered it ON after a week/10days and still showed 100%,USB mini to USB C adapter works like a charm, perfect fit on my Nexus 6P (no loose or wobbly fit),My Nexus 6P of 3450 mah got charged almost close to 5 times with this charger,Also charged my new GoPro Hero 7 black & Nexus 6P simultaneously and both got charged in 2 hrs flat,LED indicator on the device lights up for the entire duration of the charge indicating that the device is Actively charging your phone/camera etc.Carried it on my trip and this was a handy companion for my Phone when the battery drained by use of Google Maps (location/gps ON), Data/4g ON, Camera for intermittent pictures and videos and as the capacity was huge, it lasted me 2 days with multiple charges (Nexus 6p + GoPro Hero 7 black) and i was NOT worried abt charging the battery charger in absence of a power socket,The device auto-powers-off when the connected device/phone is fully charged and LED turns OFF,Device gets normal warm and NOT Hot while charging even 2 devices at the same time (which means good quality products used internally).Cons:There is NO fast Charging/Quick Charging with the supplied cable,Bulky in size (NO) but in Weight (yes) but what can you expect from a beast of a battery charger of 20K mah,2 charging cables should be provided when there are 2 ports for charging,One of the ports should be a quick charger/fast charge port with one (of the 2 cables) supporting fast charging/quick charging capability,........This is NOT a light device to be carried in your waist pouch or in your cargo trousers or inHand.Safely tuck it in...in an on-shoulder-bag and this can travel easily on international flights as well (as an in-cabin accessory)Next iteration of this Product: Should have capability of:Normal charging + Fast charging,Ability to charge the device using solar power,If you like my review, please vote/mark as helpful.Giving this device 4.5 stars as of now due to various small improvements that are still due.Thankyou CoolNut for this lovely product.

Sometimes you look for something and you find entirely something else and you are suddenly not sure whether to be happy with what you got or if you want to simply give a 4-star rating and move on with life and find another girlfriend.You know which path I took. If you still don't - I took the third path which also includes writing a review.(Full disclosure: I did not buy this product for myself. I did not even buy the product. My friend bought the product, upon my recommendation, from my account. I happened to use it fairly extensively - and hence the review)Sometimes you simply want a long lasting, no frills attached powerbank, so you ask a friend who you think knows a thing or two about technology, and he recommends a particular product, you spend your hard earned money on it and in the end, you end-up with a power bank which is more of a power brick and you get on with you life.... and you know the drill about finding a girlfriend.This is exactly what happened with this purchase.Now the real review:The brick ticks all the boxes.The rated power it almost accurate.It holds its charge wellIt has three outletsIt takes about 4hrs to charge fully (which is really good)The digital display looks nothing like how it looks in the pictures.So far, every expectation has been met. So, why the four stars? Simply because there is nothing spectacular or superlative about it. The bundled cable is short and flimsy, the casing scratches easily, and the overall buildquality is adequate.It doesn't thrill you with fine finishing like the  TP LINK TL PB10400mAH POWER BANK  with its build quality, not make you feel like giving everything up like the  Lipton Ice Tea, Lemon, 350ml each (Pack of 6) . It just does what it promises to do without too much fuss.It doesnt make you want to be a better human or pull out your red underwear and wear it on top of your pants and go whee....

Attractive design and good product, cable came with powerbank is differnt from the powerbank type charging slot. Power bank is not able to charge with this cable

If you are looking for a 20000 mah power bank and buying it for the first the first time you should definitely go for this powerbank.. It take some time(not quite but a little ) to get charged but when done it stays for a long time charges u your phone way faster... Coolnut service is also good, appreciable once I handled it miss carefully some fault happened to my powerbank I couriered the powerbank to the service center they got it fixed and returned it by courier now m using it happily.. I got it for 1800 from Amazon so u want in this price wait for the offer or else if you r really in need of a powerbank you can go for it at what current price it is it worth every penny.. So guys u can opt for this.. That's it from my sideCons:If at all looking for a con in this, then I think the weight is bit heavy (not much but yeah little which is manageable ).

Its very fast in charging same as when you connect to the phone charger(Not as fast as turbo chargers).where as remaining power banks dont give the same speed that this power bank is providing. What i dont like in this is the LED display, it is not much clear we need to observe it more carefully like when we are in more brighter environment like outside under the the afternoons sunlight. Size of this is verg huge its bigger than my moto E4 plus not much easy job to carry every where you need it.Remaining features like charging all the three phones at a time is very good. Im giving by rating 4.5 because of only that poor visibility of led display . I thought it would be as clear as shown in photos
