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.
