Best 20000 mAh Power Banks Under ₹1,500 With Fast Charging From Portronics, Ambrane, Kratos to pTron.
A few years ago, buying a power bank felt like gambling. Some charged slowly, some overheated, and others died before the warranty card yellowed. Now, things look better. Fast charging has gone mainstream, safety layers are stronger, and even budget-friendly models pack a serious punch. With festive sales and daily discounts everywhere, a solid 20000 mAh power bank under ₹1,500 feels less like a compromise and more like a smart buy. So, which ones actually deliver without heating up or slowing down after a few weeks? Let's break it down and also, check the top picks from Portronics, Ambrane, Kratos to pTron.
Before jumping into the list, a quick reality check. Capacity alone doesn't matter anymore. Look for fast charging support around 22.5W, Power Delivery or Quick Charge compatibility, and proper circuit protection. Multiple output ports help when more than one device needs power, and compact design matters if the power bank lives in a backpack or work bag.
