You might have the experience that you lose your files when it’s a blackout while you work for an important report have to finish by the day of next or need it urgen. It could be a personal problem, but if it was connected with huge amount of oney of business, it would be another story.
We are proposing some way to make sure that your files will be safe from black-out.
Placing a battery between a outlet and a plug will give you times(10-15minutes) to save your file you were working on.
