It's three charging ports can practically power up my my iPhone 6 and other devices at once making it extremely handy. I'm always impressed by how quickly this charges my phone (from 10% to near full takes approximately 1:30 hours). So far, I have been able to charge my phone about 4 times from near empty to full before having to charge the power bank. With the USB cable it comes along to charge the power bank itself as well as with some company essential cards.What I love the most about this power bank is how effective it's been. Having massive 20000 mAh capacity, obviously justifies it’s size and weight (nothing wrong with this too). As a result, I haven't charged my phone using a wall outlet since I bought this power bank more than a week ago. Not having to worry about my phone going dead or being near a wall outlet is the best feeling next to purchasing a new phone.So if you want a reliable power bank that charges your phone in no time and frees you from being attached to a wall outlet, GET THIS! ### ⭐⭐⭐⭐ MadeInIndia,TankLikeSuperBuildQuality *by A***N on 27 October 2018* 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. ### ⭐ Not satisfied with performance of device *by D***A on 9 September 2017* Hello Team,As I purchased the COOLNUT Power bank,I have noticed the device has manufacturing fault.1) I had tested the device in different way but it has failed the standard as the rated mAH compare to rated Battery mAH is wrong as per given. Please provide the Wh capacity of device.2) The device is took around 2 days around 48 hrs+ get fully charged. As the rated capacity which is very high time took to charge the battery.3) Other way tested the battery performance, drained the mobile battery and start the charge the mobile with room temperature but its taking 31min to charge 6% and another 37min to charge 17%.As the different test it is failing to perform standard. I request you please return the device.Have you received certificate UL 2056 standard for the high capacity power bank?I request you please take back the device, I'm not satisfied with performance of device. --- ## 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.gr/products/69289606-coolnut-20000-mah-qc-quick-charge-3-0-fast-charging](https://www.desertcart.gr/products/69289606-coolnut-20000-mah-qc-quick-charge-3-0-fast-charging) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-30*
