Power banks come in all sorts of shapes and sizes, but most importantly there are many different power banks that have varying power capacities. Most of the time those that are purchasing a portable charger are searching for a low power capacity one that is very small and so they’re easy to be portable with. That said, as easy as low capacity power banks are able to be taken anywhere, the negative side is that they can really only last for about a single charge to your smartphone. Low capacity power banks also don’t have many charging ports or make use of fast charging tech.

In this guide, we’re going to go over the best power banks with a 20,000mAh power capacity. At this range of power capacity, power banks are capable of quite a lot more and are generally more useful. Sure, higher capacity power banks may be larger, but you may find that the charging power benefits far outweigh the larger size and slightly heavier weight.

Anker PowerCore 20100 Portable Charger

To start out with, the first 20,000mAh power bank that we’re recommending comes from a very well-known brand, that is not only in the portable charging space but in the charging electronics market in general. This PowerCore 20100 portable charger is from, Anker. It’s one of the best-selling high capacity power banks.

As you could tell by the name of the power bank, it has a has 20,100mAh power capacity and it basically does everything at an optimal level when it comes to a standard high capacity power bank. This charger uses two USB-A output charging ports, and each of the ports are capable of a 5V/2.4A charging speed. The max output of this power bank is 4.8A. This means that you can use the max power (12W) of each port at the same time without having to give up charging speed.

The PowerCore 20100 is recharged through a Micro-USB input port that has a charge speed of 5V/2.0A. This power bank does not use Quick Charge and that’s why it’s one of the best standard high capacity power banks, with its use of fast standard charging. So it doesn’t matter if you have an Android or iPhone, this charger is practically fair to charge all USB chargeable devices.

RAVPower 20,100mAh Power Bank with Quick Charge and USB-C

This RAVPower 20,100mAh power bank is a highly capable high capacity portable charger, with its use of two fast charging technologies, that is, if you consider USB-C to be fast charging. The charger makes use of three output charging ports. There are two USB-A ports, with one featuring Quick Charge 3.0 and the other port has a 5V/2.4A charging speed. The one other output port on this power bank is the USB-C port that can be used with a USB-C to USB-C charging cable to charge USB-C compatible devices.

However, just something to know is that this power bank does not feature Power Delivery charging from its USB-C port, as it has a 5V/3.0A (15W) charging speed. It can still charge USB-C compatible smartphones and also a few USB-C laptops, but it won’t be able to charge larger, more powerful USB-C laptops like the Dell XPS 13 / XPS 15 laptops that require more charging power. The USB-C port on this power bank is able to charge the USB-C MacBook though, just not at its max charging speed, as this power bank does not feature Power Delivery charging with this USB-C port.

To recharge this power bank, there are two options that you can choose to recharge it. There’s a Micro-USB input port that’s Quick Charge compatible and the USB-C port can be used as an input port to recharge the power bank. So, the Micro-USB input has an 18W max recharge speed, while the USB-C input has a 15W recharge speed, no matter what input you’re using, we highly recommend using a Quick Charge wall charger to recharge this power bank at its max charging speed.

Tronsmart 20,000mAh Presto Power Bank with Quick Charge and USB-C

Another 20,000mAh power bank that uses Quick Charge and USB-C, is from Tronsmart. Tronsmart is a brand that’s released only a few portable chargers on the market but the ones they do release hold a lot of value. Such as there two 10,000mAh power banks, with Presto power bank uses a Quick Charge port and a USB-C port, and the other, standard version using two USB-A ports.

This Tronsmart 20,000mAh portable charger basically combines both of Tronsmart’s lower level chargers. As this charger makes use of three output ports. Just like the previous RAVPower charger, this charger also uses two USB-A ports, with one using Quick Charge and the other one has a 5V/2.4A charging speed.

EasyAcc 20,000mAh 4-Port Power Bank

It’s pretty normal for a power bank to make use of multiple charging ports, that said, most of the time it’s two or three ports on high capacity power banks. This EasyAcc power bank goes a little further as this charger makes use of four USB-A charging ports. Each of the ports on this power bank is able to output a charging speed of 5V/2.4A, at the same time, the max output of this power bank is 4.8A. So you can use the max power of two ports at once, but if you’re charging three or four devices, then the 4.8A max output will be split up between the devices that you’re charging.

It’s an equivalent exchange kind of situation, as charging four devices at once with a portable charger can be very useful as you don’t have to be restricted with a wall charger and so you’re charging your devices where you want. The recharging of this EasyAcc power bank is just as impressive as this charger makes use of two Micro-USB input ports that can actually be used at the same time to recharge this power bank faster.

Each of the two Micro-USB input ports on this power bank has a 5V/2.0A recharge speed, so when you use two of them at the same time you’re able to recharge the power bank at a 4A recharge rate. This results in this 20,000mAh power capacity be able to refill within just 5 hours.

EasyAcc 20,000mAh MegaCharge Portable Charger with 5A Input and QuickCharge

Another EasyAcc power bank is their MegaCharge portable charger model. This charger is basically an upgraded version of the previous charger if you’re someone that can make use of its faster charging tech.

As this MegaCharge power bank also has four charging ports, but it’s more powerful charging. There are three USB-A ports, with one of the UBS-A ports using Quick Charge. The other two USB-A ports have a 5V/3.0A charging speed. The fourth port is a USB-C port and it has a 5V/3.0A charging speed. So it’s definitely for those that own a Quick Charge compatible smartphone or a USB-C compatible device, too.

The recharging for this power bank is also very good and that’s because this also uses two input ports, but the recharging speed for this power bank is faster than the previous EasyAcc power bank that we mentioned.

Aukey 20,000mAh Power Bank with Four Outputs and Three Input Ports

This Aukey 20,000mAh power bank is quite similar to the previous EasyAcc power banks that we mentioned, as this charger also makes use of four output charging ports, However, this power banks take it a little further with it using three different input ports for recharging.

So there are three USB-A ports that each have a 5V/3.0A charging speed, and the fourth output is a USB-C port with a 5V/3.0A charging speed. This power bank does not use Quick Charge, and we think that a charger like this using Quick Charge would have made it more valuable.

To recharge this power bank, you have three different options for recharging, and they can also be used once at a time to recharge the power bank. There’s a Micro-USB input with a recharge speed of 5V/2.0A, Lightning input with a recharge speed of 5V/1.5A, and fastest way to recharge this power bank is to use the USB-C port as an input as it has a 5V/3.0A recharging speed. Definitely, a versatile power bank as there are very few portable chargers on the market that make use of a Lightning input, which can be useful for iPhones users.

Power Delivery charging is most common with high capacity power banks, and that’s another benefit of getting a high capacity power bank. Power Delivery is basically fast charging that’s compatible with the new standard of USB-C. Many devices are now using USB-C such as new Android smartphones, tablets and there are now many laptops on the market that make use of USB-C, too. As a result, you can actually charge certain laptops that use USB-C with a portable charger. This Jackery SuperCharge portable charger is one of them.

This Jackery power bank makes use of two charging ports. With one being a 45W USB-C Power Delivery port and the other port is a USB-A port that uses Quick Charge 3.0.
