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. No doubt however that we’re talking about a heavy power bank that weighs a bit less than half a kilo (475 gr.)
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.
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).
When you’re done, long press the power button for 2 seconds to switch the charging & discharging mode freely. The battery pack uses exclusive technology developed by Pisen engineers to control its temperature when charging. 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. 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.
