    Not just a surge protector but also a power bank.

    Since we keeping losing power and afraid of power surges I ended up getting this to help protect my Wife and daughters desk top. Even when the power goes out this is also a power bank and still has power to power what ever is pluged into it. Bought 2 first and might have to go back to to more.
