The tag "credit card" sized is a bit misleading... Its more of a "Credit Card Box" sized
@jovisjoseph Well, true. Still, i think it's pretty convenient.
Though I like the product, "Credit card size" is a clickbait.

When I saw "Credit Card Size" I thought it was going to be tiny! It's around the same size as my Anker PowerCore 10,000mAh. The Supermini is slightly smaller though.
@helloromero SuperMini is smaller than Anker PowerCore and can supply up to 18W with USB-C Power Delivery or USB-A Quick Charge 3.0.
Hey Product Hunt. And thank you @chrismessina for hunting us. A couple of months ago we launched our first product SuperTank here. Now we are super excited to launch our SuperMini. SuperMini is 30% smaller than a traditional 10,000mAh external battery, so it fits in virtually any bag or pocket. Here’s how we did it. SuperMini uses a type of battery cell called 21700. Each cell provides 5,000mAh of charge capacity, making them 50% more energy dense than the cells used in a typical chargers. It takes just two of these cells to reach 10,000mAh, while most portable chargers use three cells. SuperMini also supports up to 18W of fast charging capability through both its USB-C port and USB-A port. With up to 18W of Power Delivery (PD), SuperMini can charge iPhone X up to 50% in 30 mins with a USB-C to Lightning cable. Would love to answer all your questions and hear your feedback.

The one thing that I really didn't like about portable chargers was the recharge speed. But considering that you've been able to cut it down to 3 hrs and package it all in such a small form factor is really great👍🍻
@akash_sharma10 Thanks a lot for your kind words and feedback, Akash.
