Energy has become one of our main needs these days, especially for those of us who are professionals or just like to use their tech gadgets all the time. The market nowadays is full of decent offers in terms of power banks, with battery capacities ranging from… a few hundreds mAh up to… 20.000+ mAh for those power hungry!
PISEN is not a small company in this specific market segment, as they have become a smart technology provider with leading global sales to over 200 million customers. For more than ten years, Pisen, known for its stable performance and user-friendly designs, has provided satisfying products for customers from 35 countries and recently they were kind enough to send us their most powerful energy “machine” known as 20000 mAh LCD Display Power Bank.
Here’s how it did during our lengthy trials 😉

No doubt however that we’re talking about a heavy power bank that weighs a bit less than half a kilo (475 gr.) so it’s not something that you can easily carry on your pocket, or in a small purse. I use it in my back pack, that has an external USB port for direct charging my phone – when necessary- and this way it’s not causing any issues when travelling or walking in the city.
DUAL USB OUTPUT
This is something that can surely make your day in case of… need. It comes with Dual USB Ports (2A+1A Output), that are able to detect your device intelligently and deliver the optimal charging (Up to 2A Max).
This means that if your phone supports charging up to 1A/1.5A then the PISEN 20000mAh LCD Display Power Bank will regulate the current in order to charge the phone safely. If on the other hand there’s a device that can withstand up to 2A of charging, then you will get the full charging power of the device.
LCD DIGITAL DISPLAY
Yepp, this is a feature I really enjoyed using. The PISEN 20000mAh LCD Display Power Bank comes with a pretty accurate LCD display, that shows you the remaining power in percentage – 1% accuracy minimum. It also shows which port you’re using at each time (OUT1 – OUT2) and it has a smart function that can annoy you, when it needs to be recharged.
To activate the LCD display you just have to long press the power button for 2 seconds. Don’t worry about energy consumption, as the backlight goes out in 15 Seconds to save energy.
easy to use display, with 1% accuracy
CHARGE & DISCHARGE SWITCH
So how do we turn the juice on? Juts connect the power station with your device and power supply simultaneously with the micro USB cable provided (if your phone supports it) or your own cable (Lightning or USB Type-C). When you’re done, long press the power button for 2 seconds to switch the charging & discharging mode freely.
That’s all, the charging procedure will begin 🙂
COOL UNDER PRESSURE
The battery pack uses exclusive technology developed by Pisen engineers to control its temperature when charging. If high temperatures are detected then it automatically modifies power output to reduce heat. It also has a security feature that can spot any short-circuits and cut-off charging procedure for protection.
According to the manufacturer, the Pisen 20000mAh external battery charger provides over-charge, over-discharge, over-heat, over-voltage, over-current and short circuit protection. This means that in any given situation you will be protected if something might go wrong with a cable, an over-charge of your smartphone/tablet or just a mishap.
With a starting price tag of just 28$ this massive 20000 mAh power bank from Pisen proved to be decent for its money’s worth, fulfilling completely all my charging needs for my smartphone, laptop and my wife’s phone as well, with one single charge.
It takes quite sometime to charge it with a 2A charger (11 hours per average) but then you will be able to use it for several days with no issues. It offers impressive performance in everyday use, quite good quality build (with faux leather design) and you can find it available in two colors: white and black.
