THE MAGNUS OPUS 21000MAH
The 337g heavy glossy enclosure of the Magnus Opus measures 162mm in length, 65mm in width and 21mm in height.
Once again to see just how large or small the powerbank we have here is we placed the Magnus Opus it right next to several other models we're using in the lab including the CHJGD Ultra Compact Powerbank 10000mAh, Xtorm AL420 9000mAh, Luxa2 PL3 10400mAh models and the Luxa2 PL2 6000mAh.
At the top we find the small LCD screen and the power button (pressing the power button once turns the LCD screen on while pressing it twice lights up the LED torch).
As mentioned earlier the Magnus Opus is perhaps the only powerbank to ever pass from our lab that features a formed enclosure for your thumb and index finger.
The micro USB charging port is placed at the front of the enclosure right beneath the LED torch and the two USB ports.
Both the input and output electrical specifications are listed at the rear of the enclosure.
