Ambrane 100W Fast Charging Powerbank for MacBook, Type C Laptop & Mobile Charging, USB-A Output 25,000mAh Battery, Triple Output, Power Delivery & Quick Charge (Powerlit Ultra, Black)

Highly useful and effective charger for laptop.

Don't waste money, i purchased it 1year ago and used it hardly 3 or 4 times to charge my mobile only. Now when checked its not charging just a blinking white circle, when un plugged no lights and not charging. Don't get cheated by the look and working at the starting days, Once the warrenty is over this will stop working, A product with price almost toching 5000, have only 6month warrenty. when I complainted with email see what they says

Facts:- With this capacity this can charge a dell latitude 0-90% when the laptop is not in use and 0-70% when laptop is in use.- Very fast type c laptop charging and similarly this would discharge quickly as well.- i work for 10 hours. Say I am not at home and have to work. If my laptop is fully charged. 3-4 hours my laptop will take care and rest 4-5 hours this will take care easy. if I set my laptop on low brightness/ power saver mode - Additional 1.5 hours.- Alone this or any laptop can’t take care of a full day of work. You need both.Whom this is for as my my understanding:- To use for laptop in case of travel/ airports delays/ car trip / vacation/ in case you have some major power outages in you area due to rain / repair and you work from home mostly.- I don’t think this one should buy for mobile charging for 2 reasons. First why to pay 4 times when we have other options and secondly usb out wattage is not that high . 1k power banks have better and its not safe for the mobile device (which can’t step down) to be connected to 100watt type C.

I'd earlier bought the lower capacity version of this powerbank (20,000 mAh/85W fast charging). I was quite happy with that powerbank but felt a higher-capacity one would be useful as I go on multi-day treks in the Himalayas and need a powerbank that can charge multiple devices multiple times.I was initially quite apprehensive about buying this powerbank as I'd seen several bad reviews, mostly of the powerbank overheating dangerously while charging/being charged. Found a good deal during the recent Amazon sale so decided to buy it anyway. My observations:1. My powerbank faced no overheating issues while being charged - I use a Vivo 100W charger and it takes about 2 hours to charge fully - not bad considering its capacity.2. I used it to charge my phone and laptop a few times - again, no issues of overheating. It can charge my Vivo X100 Pro fully 4 times, which is good. It also charges my laptop to about 70% if I connect the powerbank to the laptop and I'm not using the laptop for anything - I assume it would charge the laptop far less if I was actually using it.3. While it is heavier than the average powerbank, it is perfectly manageable - I'd say it's reasonably compact and light considering its capacity and charging speed - it is FAR lighter and more compact than the Portronics Ampbox 27k. It's not the kind of powerbank you can carry in your pocket, though.4. The 20k mAh version of this powerbank has two USB-C sockets and one USB-A socket. This powerbank, rather strangely, has two USB-A sockets and only one USB-C socket. This is slightly annoying as everything is moving towards USB-C, not the other way around. Deducting one star because of this inconsistency.However, I still think this is a very useful high-capacity powerbank and am happy with my purchase (one month down the line - will update this review later in case of any issues)

It’s been ages and it’s works as charm, i feel it’s your luck for electrical items but go for it.

I purchased this Ambrane 100W Powerbank in June 2025 for ₹4,999, thinking it was a premium product for emergency backup. Unfortunately, my ₹5,000 has gone down the drain.The Issue:I have barely used this power bank ONCE for 20 minutes since I bought it. My plan was to keep it fully charged for power cuts. However, I discovered a major defect: Severe Self-Discharge. I charged it to 100% and kept it aside. When I checked after a week, it was completely dead (0% battery) without being connected to any device. I tested this twice to be sure, and the result was the same. It cannot hold a charge for even a few days.Conclusion:Don't be fooled by the outer build quality; the internal material and battery cells are of 3rd class quality. This is my second product from this brand, and both have failed prematurely. It is painful to lose hard-earned money on such unreliable tech. The price has dropped to ₹4,400 now, but honestly, it is not even worth ₹500.Verdict:Please save your hard-earned money and look for better brands. Highly Disappointed!

Charging very fast

My Macbook charges for just about 4 hours which is less than expected. My 6000 mAh mobile charges for about 3 times only. I surely expected 25000 mAh power bank to charge mobile at least 4+ times, and give more charge to macbook. Either specifications are not correct or it doesn't work as claimed.
