I investigate and take a look at a wide variety of batteries, together with some which have been scaled-down than a Tootsie Roll (for tiny gizmos like a stylus or penlight) or bigger than an overweight English bulldog (to help keep important electronics functioning throughout an influence outage or camping trip).
Around the size and shape of a little Personal computer tower, this UPS has 12 outlets in full, 6 of which it backs up While using the battery.
