Best 20,000mAh Power Banks

Smartphones are using larger batteries every year. Just take a look at the new Samsung Galaxy S21 models. The base S21 has a 4,000mAh battery, the S21 Plus has a 4,800mAh battery, and the S21 Ultra has a 5,000mAh battery. You also have budget smartphones such as the Moto G9 Power with its 6,000mAh battery capacity.

Even the iPhone, a smartphone that always uses a relatively small battery because of its excellent battery management, has started using larger batteries. The iPhone 12 Pro Max uses a 3,687mAh battery. The need to use larger batteries is because of phones using better specs every year.

A new processor, more RAM, better quality cameras that have better AI processing, higher resolution screens, and higher refresh rate screens have been using more battery power. If you’re using these powerhouse smartphones, then it’s wise to use a high capacity power bank that can charge these phones to full power a few times, as you don’t have to worry about recharging the power bank so often.

In this guide, we’re covering the types of 20,000mAh power banks that you should consider when charging your smartphone or other devices such as tablets. A 20,000mAh portable charger features a high enough power for multiple usages and fast charging technology.

RAVPower 20,000mAh 18W Power Delivery Quick Charge Power Bank

RAVPower is one of the larger brands when it comes it comes to charging electronic products. This portable charger has a powerful charging all-around and features three output and input ports.

There are two USB-A ports on this power bank; one of the USB-A port uses Quick Charge 3.0, and the other only has a standard 12W charging speed. The one additional output is a USB-C Power Delivery port with an 18W charging speed. The Quick Charge port can fast charge most Android smartphones, as most are compatible with Qualcomm Quick Charge. Still, for universal charging, you should use the USB-C Power Delivery port as Power Delivery is compatible with nearly all Android phones and iPhones.

When it comes to charging Android phones via a USB-C port, you have to use a USB-C to USB-C cable, and with iPhones, you have to use a USB-C to Lightning cable.

Recharging the power bank can be done through the USB-C port, Micro-USB, or a Lightning port. If you’re an iPhone user, this power bank is worth getting as most power banks don’t use Lightning input ports. This charger also has an LCD that shows the remaining power capacity and uses fast charging via the PD or Quick Charge port.

RAVPower 20,100mAh 45W Power Delivery Power Bank

20,000mAh power banks are also known to have more powerful fast charging, such as Power Delivery ports that use a charging rate higher than 18W. That’s the case with this RAVPower 20,100mAh portable charger, as this one has a 45W USB-C Power Delivery port. An 18W PD port is not enough to charge USB-C laptops, and the standard for a PD port is to have a 30W charging speed or higher.

With a 45W Power Delivery charging speed, you’re able to charge most USB-C chargeable laptops either at or closer to their max charging rate. This means that you can use this RAVPower power bank to charge Macbooks, Chromebooks, Microsoft Surface devices, and in our tests, you can also charge Lenovo laptops such as the IdeaPad Flex 5. You can still fast-charge smartphones with the USB-C port on this power bank, and don’t worry, and they will not get damaged as the charging rate adjusts to the device you’re charging.

There is also a standard USB-A port that has a 12W charging speed.

You can also recharge the power bank at Power Delivery speeds or use the Micro-USB input port. This charger does not include a PD wall charger, but it does come with a USB-C to USB-C cable, so you can start using it right out of the box.

Villain 20,000mAh 20W Power Delivery Power Bank

This Villain power bank follows the same formula of fast charging with a high power capacity. The portable charger has a 20W USB-C Power Delivery port, a bit higher than others in this guide. The other two ports are a Quick Charge 3.0 port and a standard USB-A port with a 12W charging speed.

To recharge this Villain portable charger, you can either use the same USB-C Power Delivery port or the Micro-USB input port. It’s best to use the USB-C port as you can recharge the power bank at PD speeds, while the Micro-USB port only has a 10W recharge rate. The charger does use a digital display to show the power capacity that you have left, instead of a few dots that most power banks tend to use.
