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)

Quality is topnotch, battery life.

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!

good product. works well and charges well also. sturdy design so it lasts long. had fallen from height many times but still works fine. i am able to charge both my laptop and mirrorless camera with it.

Overall, the performance is good. A full charge provides enough power to charge 3–4 mobile phones to around 80%. However, the charging time is quite long, as it takes more than 4 hours to recharge completely.

Good one for on the move office work..Peace of mind when you have a charged laptop on the car

Don't buy. you expect it to work for years to come but stopped working in 8-9 months. Unfortunately warranty is about 6 months. Of 10 battery charge indicator light it is now not going over 1st light. I use it occasionally but have never felt confident due to its silent discharge.

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.

Writing this review after 2 years of use . It worked fine for first 1 year later I noticed that it does only work if there are minimum 4 points. If light blinks less than four then device will not be charged.
