Top 5 Best High-Capacity Power Banks with Over 20,000mAh Battery

Even with the advancement in technology, we have yet to see a gadget that can power you through at least two days of heavy usage. The good news is, there is a plethora of high-capacity power banks you can buy that are ready to feed your power-hungry devices throughout the day. Also, high-capacity power banks can be your lifeline should you find yourself in remote areas with no access to electricity.

All of the power banks below have one thing in common: They are portable and have high-capacity batteries. These power banks aren’t pocket-portable, though, but they are compact enough to fit in your backpack, glove box, or laptop bag with ease. Without much ado, let’s dive into the best high-capacity power banks with over 20,000mAh battery that you should buy.

Anker has established itself as a leader when it comes to charging devices, and the PowerCore+ 26,800 PD is the epitome of their work. As you’d have guessed based on the name, this power bank has a 26,800 mAh power capacity, which is huge enough to charge most smartphones over 7 times. But the colossal capacity is not the only thing that makes the PowerCore+ 26,800 PD our top choice.

The PowerCore+ comes with support for USB-C PD 30W output. USB-C PD supports a vast range of varying voltages, including QuickCharge 2.0, commonly used by the latest Samsung and Google devices. This power bank boasts of 1 USB-C (30W) and 2 USB ports (5V/3A), each with PowerIQ technology that offers the fastest charging speeds for phones and tablets.

The PowerCore+ 26,800 utilizes Power Delivery technology that enables it to fully recharge in slightly over four hours, which is three times faster than other portable chargers of this capacity. Not only does it charge smartphones fast, but it can also charge iPads and compatible MacBooks at high speeds similar to the Apple wall chargers. It can also charge select ultrabooks that support USB-C, such as the Pixelbook.

Ravpower 26,800 PD is another great, high-capacity power bank that can keep your devices powered for a whole week. Just like the Anker PowerCore+ 26,800 PD. This power bank has a 26,800mAh battery capacity and a very sleek design. Dubbed the best and fastest power bank for iPhones, the Ravpower 26,800 can charge an iPhone 6s ten times and an iPhones 7 or later nine times.

The Ravpower 26,800 can also charge Android devices at more than twice the speed of the regular wall chargers. This power bank comes with support for USB-C 30 watt output. It can recharge in four to five hours through the USB Type-C port. You can also charge it via the standard ports, but it will take around fourteen hours to recharge fully.

At around $80, the Ravpower 26,800 PD is cheaper than the PowerCore+ which retails at $129. However, the Ravpower doesn’t include a USB-C PD wall charger in the box. One advantage of the Ravpower 26,800 PD is that it can charge a Nintendo switch when it’s being played.

With a built-in bright LED flashlight and a massive 26,000mAh battery, the EasyAcc 26,000 power bank is great for travelers and outdoor enthusiasts. This power bank provides four USB ports and two Micro-USB inputs (4A) that can work in tandem to decrease recharging time by up to fifty percent. With this power bank, you can charge up to four devices simultaneously.

Technology-wise, the EasyAcc power bank isn’t left behind. It comes equipped with Fast Smart Charge technology that is one of its kind. This technology automatically identifies the type of device plugged in and delivers the fastest charging speed for that device, up to 2.4A or 4.8A through the 4 ports.

The EasyAcc 26,000 power bank also comes equipped with an intelligent integrated circuit protection system that ensures complete protection for you and your devices. It will take approximately eight hours to completely recharge the device, which is half the time taken by the Ravpower 26,800 via the standard inputs.

It may not have the highest capacity battery, but the Anker PowerCore 20,100 (check out our review here) makes a strong case for being on the list of the best portable high-capacity power banks. First, it’s the only power bank on our list with over 20,000mAh battery that can fit in your pocket. Yes! It’s pocket portable. Secondly, it weighs as little as a cup of soup.

The PowerCore 20,100 delivers 2.4 amps to both of its ports for a total of 4.8 amps. It combines Anker’s world-renowned PowerIQ and VoltageBoost to deliver superfast charge to a wide range of devices. This power bank has been designed for use with virtually any device that charges from a USB port.

On the front of the PowerCore 20,100 are four blue charging LEDs that indicate how much charge is remaining on the device. This power bank recharges itself fully in ten hours, and you can expect six to seven charges from it when it’s fully charged.

The Aukey 26,500 mAh power bank is another great choice if you’re looking for a portable charger that will keep your devices powered for an extended period of time. The company claims the Aukey 26,500 can charge your iPhone 8 ten times or the Galaxy Note 8 six times on a single charge. That’s pretty impressive considering these devices can go a day on a single charge.

The Aukey 26,500mAh power bank offers four output ports and three input ports, which you might not find in any other power bank. Besides charging your smartphones and tablets, you can also use this power bank to charge a compatible USB-C laptop since one of the ports is a USB-C port. The other 3 output ports are USB-A ports – one offers a 5V/2.4A, while the other two have a 5V/3.0A charging speed.

One of the downsides to this charger is that the USB-C port lacks the Power Delivery feature. This means it can only charge a few USB-C laptops. About recharging, you can recharge it via USB-C, lightning, or micro-USB port, which makes it a truly universal power bank.

The power capacity of a portable charger carries a lot of weight when making a buying decision. That’s because a power bank’s capacity not only affects its portability but price, too. You can get a power bank with as low as 3,000mAh battery, some as small as the size of a credit card. However, such power banks can only charge your device once.

There are also ultra high-capacity power banks with up to 50,000mAh batteries. Such power banks tend to be bulky and also come with a higher price tag. In the end, it will boil down to your personal preferences.
