Many phones don't last the entire day, all thanks to our continuous phone usage. You'd be able to relate to it more if you are always on the move with no access to power outlets. This matter turns worse if you're not on Wi-Fi, as phones tend to use more power when on less efficient LTE connections.
The most obvious solution for folks who want more juice is to invest in power banks. And if your smartphone has Quick Charge 3.0 support, you refuel it swiftly and rapidly.
In this post today, we present a list of the best Quick Charge 3.0 power banks. But before we get down to it, let's see what should you check out while buying one.
Note: Qualcomm's Quick Charge standard is different from the other charging technologies. Before you make your purchase, do make sure that your phone is Quick Charge 3.0 compatible to make it work.
What to Look for When Buying Power Banks
Does your power bank check the following boxes?
Product portability (weight & volume) of the product.
Does it have warranty coverage?
Last but not least, the actual capacity.
You wouldn't want to invest in a device that takes an eternity to charge. If you're looking for a product which fuels your phone at a considerably good speed, it should do the same with itself.
Plus, take into consideration the conversion loss and the actual capacity. Yeah, power banks hold substantially more power. However, it'd be wrong to assume that a 5000mAh portable charger will be able to yield two full battery charges for a 2500mAh battery.
So how do you calculate it? Let's take a look below.

How to Calculate Power Bank Capacity
By default, the power rating of a phone is calculated at 5 volts. But when it comes to power banks, it's estimated at 3.7 volts since they carry Li-ion battery cells inside. Naturally, this causes a step down in the charge cycles.
Calculating the actual capacity as opposed to the marketed one requires a bit of math. For instance, if a power bank has a capacity of 5000mAh, then the total energy will be 18500mWh (5000mAh x 3.7V, mWh being watt-hours).
So, if we convert that at 5V, the stored capacity will be 3700mAh (18500mWH / 5V). Now, this capacity has to take into consideration simple laws of physics like resistance and heat loss. Also, the conversion efficiency comes into the calculation which finally determines a nearly actual capacity of a typical 5,000mAh power bank.
Also, shorter the wire, lesser will be the resistance. Hence, shorter charging wire will benefit you the most.
The Aukey 30000mAh USB-C Portable Power Bank has over 67% positive reviews and bears the tag of Amazon's Choice. This one has an insane capacity of 30000mAh.

The Micro USB port for input comes with 2.4A charging support. At 30000mAh, you can expect the actual capacity of the power bank to be around 20000mAh, which is enough for most power users.
As far as the user experience is concerned, it collects pretty good reviews with many users being praising Aukey's customer care.
On the downside, this one doesn't have any dedicated notification LED light. The power button changes color to indicate the different power levels to help you know the status.

If you're looking for a power bank with plenty of ports, the ZeroLemon ToughJuice V3.0 is the one for you. It has a total of five ports, with one of them reserved for QC 3.0. The crux of this power bank is its massive 30000mAh capacity, and it comes at a catch — size. The ToughJuice V3.0 is a tad bigger and weighs approximately 1.25 pounds.
The only issue which I see with this one is that the other three ports are for 1A charging. So the phones will take its own sweet time in getting to refuel.
Another thing about the ZeroLemon ToughJuice V3.0 is that it takes a long time to juice itself. So, you might want to take these two things into consideration before you make the purchase.
On the upside, it has a USB Type-C port using which you can charge your MacBook (not as fast as a wall charger, though). Plus, there's a protective casing to protect it from regular wear and tear, and also prevent ugly fingerprint smudges.

This power bank allows charging two devices at a time. Furthermore, it features a Low Power mode using which you can fuel your low-power Bluetooth devices.
The recharge time is around 6 hours. I have been using the Mi Power Bank 2i on and off since the last one year, and it has served me well so far. The product is durable and strong, and charges compatible devices as it should.

Many people consider battery packs before investing in a power bank. Though the former is useful, they do have their shortcomings. First, they are not future proof, meaning that you have to change them when you buy your next phone.
Second, considering their price, they do not have the same power output. And let's not go into the charging speed. In the end, they end up being a disappointment.
On the other hand, power banks are future proof, and you can carry most of them with your belongings. So, which one of these will you get?
