If you are looking for an external battery, there are many options that you have today on the market. For years we have had multiple options, but the truth is that today we cannot look for just any battery, but it is good that we look at its technical characteristics. Here are the 5 best fast charge compatible external batteries.
1.- Aukey PB-T4
10.000 mAh with which you can charge any smartphone battery two, three or up to four times depending on the battery capacity of your mobile. You can also charge any tablet, and since it is a battery with a port compatible with Quick Charge 2.0 technology, you can also use it to quickly charge any smartphone, or even iPhone and iPad at high speed. In this case we find an input port to charge the battery itself, a standard output port to charge any device at normal speed, and a high-speed output port for the devices with which we want to use fast charging.

2.- KINPS 10.000 mAh
Another option that is also the most economical is the KINPS battery, which presents us with a capacity of 10.000 mAh, despite having such a cheap price at this time of only 13 euros, thus being one of the best options if we want to spend as little as possible.

The best of all in this battery is that it has two output ports compatible with fast charging, with a voltage of 5 V and an intensity of 2,4 A. All this with an input that is also fast charging, so that we can charge the battery more quickly than in other batteries that, although they do have fast charge outputs, sometimes they do not have fast charge inputs and take a long time to charge.
3.- RAVPower Ace Series 22.000 mAh
A battery with no less than 22.000 mAh to charge the devices that we have a lot of times, or to charge several of them at the same time. We say this because the battery stands out especially for having three different ports to charge three different devices. It is compatible with standard fast charging, being capable of reaching 2,4 A in each of the ports independently, with a total intensity of 5,8 A when we use all the ports simultaneously.

4.- Vinsic 20.000 QC 3.0
It is one of the most versatile batteries that we are going to find. It has four different ports. One of them is a standard USB port for charging devices with normal charging technology. Another is a Quick Charge 3.0 port for charging devices with Qualcomm's latest charging technology. The other port is a USB Type-C that serves both as an input and an output to charge the battery or use the battery to charge other devices. And then it has one last microUSB port to charge the battery. Thus, we have a large number of options in a unit that has a capacity of 20.000 mAh.

5.- VIVIS 20.000 with double charging input
However, when we have very high capacity batteries, it is not only relevant that they have double output, or that they are capable of charging other devices in fast charge. It is not even enough to have a fast charge for the external battery, because even then we will have to leave it charging overnight. However, the VIVIS 20.000 not only has two output ports, but also two input ports to be able to charge the external battery with two chargers simultaneously, reducing the charging time of this battery in half.
