With the support of Group 35, our friend and colleague Viktor Dolgopyatov has developed for the military power banks that can survive a year in the trenches, do not explode from a bullet and even continue to work if they move by pickup.
The capacity of such power banks is up to 200,000 mAh, while conventional ones have about 10,000 mAh. That is, they are 20 times more powerful than conventional power banks. The devices have up to 12 USB ports, which makes them convenient for charging several phones or other gadgets at once.
Powerbank has an aluminum body, charges from 220V, and takes about 6 hours to fully charge.
Each such invention brings us closer to victory!
