power bank
A power bank is the portable savior that rescues smartphones from the dreaded low-battery doom, while itself being a burdensome constant companion. It offers candy named electricity anywhere, anytime, yet emits heat under the guise of fast charging to prove its own worth. It extends the life of your device but shatters the ideal of a light load, asserting itself at the bottom of your bag. It deprives you of the freedom of outlets and binds you with cables, a revolutionary child of power in the new era.
