We live in a time when there’s always a need to use our electronic devices. Whether it’s your smartphone, tablet, or laptop, we have to use those devices for either leisure reasons or work reasons. With the absurd usage comes the need for charging these power needing devices. Power banks solve the low capacity problem and with these large capacity power banks (Power banks that are about 20,000mAh or more) can charge devices many times and charge many devices at the same time.
Power Banks in this Guide:
These kinds of power banks aren’t going to fit into your pocket, or at least not comfortably, but they are going to leave a lasting impression with their massive capacity.
#1: EasyAcc Monster 26,000mAh Power Bank
The EasyAcc power bank is a highly efficient high capacity power bank with a capacity of 26,000mAh. The capacity of the power is quite amazing because whether it’s a smartphone or tablet, the EasyAcc Monster can charge devices multiple times. This power bank can charge four devices at the same time, and with EasyAcc’s smart tech charge, each device can charge as fast as possible through detection.
LED Lights at the top of the power bank indicate how much power is left in the power bank. The power button of the power bank is to the side of the power bank. Along with the four output charging ports, there’s a LED flashlight just in case you’ve taken the power bank on a camping trip or you’re in a dark setting.
These power banks can charge pretty much everything that runs on a USB cable. For example, there are some electronic snooker cues which can be charged using a power bank.
The power bank has two Micro USB recharging ports on the side:

Just another large capacity power bank? Think again. This power bank not only has a whopping 30,000mAh capacity but it also has some awesome charging tech. The power bank has a Quick Charge 3.0 charging port on the left which means that compatible devices with Quick Charge 3.0 or 2.0 can charge at very fast speeds. If you don’t have a Quick Charge compatible device, that’s okay because the two charging ports on the power bank feature AiPower charging which can charge your device up to 2.4A charging speeds.
Type-C Recharging
There’s a power button on the top of the power bank that also serves as a power indicator by changing colors to show what the capacity of the power bank is. The power bank has two options for recharging. You can either use the Micro USB port to recharge it or you can use the USB Type-C port to recharge the power bank. We recommend using the Type-C input port because it’s most likely going to be faster since Type-C is overall faster at charging.
The power bank features a LED flashlight in between the two USB charging ports as well.
The most surprising aspect of this power bank is the length. Almost matching the length of the iPhone 6 Plus, the power bank is quite small but when it comes to thickness…Well, that’s when you can’t fit it into your pocket.
