    Bought this to allow my 90 year old mother to lower herself out of her power recliner in the event of a power failure. Has already used it twice and worked like a charm.

    I have had this device for about a month. It powers a Bunker Hill security camera console. It seems to be doing a very good job, so far. I'll still have to wait and see.
