![]() With that out of the way, let's take a closer look at the the Type-C power banks we tested. This means that though your power bank is advertised a “10000mAh power bank”, it will have just about enough juice to charge a 3500mAh smartphone twice over, not accounting for normal electrical losses resulting from the various circuits involved. In other words, a typical 10000mAh power bank will have an output capacity of around 7000mAh, though the exact value varies from one manufacturer to another, and is often buried in the products' detailed specifications. Note that all of the power banks we tested support features like the ability to charge multiple devices at once, powering off automatically when you remove the cable, and automatically charging a device when you plug in a cable.Īlso note that nearly all power banks advertise their battery capacities at 3.7V, while USB devices typically draw 5V, so the output capacity of the power banks for end-use is actually lower. We also used the same cable to charge phones across different power banks, and put the phones in flight mode to eliminate any variables. So power banks that do not support some kind of fast charging with their Type-C ports did not fare as well as they would if we had been using their Type-A ports.īest Wireless Chargers You Can Buy in India Right Now Note that we restricted ourselves to charging the phones and the power banks themselves using their Type-C ports, since that's the focus here. We first observed how much a phone could be topped up in thirty minutes, and then checked the time each power bank took to fully charge each smartphone. The second set of tests was designed to measure the amount of time it took to charge each smartphone. The phones that we used all have relatively large batteries - the Xiaomi Mi Mix 2 (3400mAh), iPhone XS Max (3174mAh), Samsung Galaxy Note 8 (3300mAh), and Google Pixel 2 XL (3520mAh). The first test involved charging a series of fully drained smartphones (all with batteries that were at full health, meaning at or near their own rated capacities), and then seeing whether or not each power bank was able to charge as many smartphones as the rated capacity would indicate. We wanted to test the power banks on two factors - if they live up to their rated capacities, and the speed at which they charge. ![]() ![]() We then proceeded to use these in the real world over a few weeks as well as run them through a standard set of tests in our labs. Then there are others - such as the Mi Power Bank Pro - that feature a Type-C port, but it is only to charge the power bank itself, and it cannot be used for output.įinding a power bank with Type-C output in India was a surprisingly difficult task, but we managed to find a few models. Most power banks out there have regular Type-A USB ports for output and a Micro-USB port to charge the power bank itself, which means you will need to carry around two extra cables just to make the power bank work for you. On the other hand, if you have a phone that ships with a Type-C charger - like most flagships do - and a cable that's Type-C at both ends, or if you are someone who is trying to go all-in with the Type-C lifestyle - maybe using an iPad Pro or a MacBook Air - your choices in terms of accessories - and especially power banks - can be pretty limited. That means you use a Type-A to Type-C cable for charging, so you won't need any extra cables if you are in the market for a power bank. However, most affordable phones ship with chargers that still have the Type-A (or as you probably know it, the “regular”/ “big” USB port). In the last few months, we've seen it trickle down the price points, and it's no longer uncommon to see phones under Rs. The Type-C port has been around for a while now, and most, if not all, Android flagship smartphones these days sport the modern USB port.
