I saw this product one day at the store and thought I would pick it up for review. It, the Rayovac PS73-4BT6 7-Hour Power Back Up, filled a nice I had been looking for. I like the idea of small back up power chargers but not the ones with built in batteries that can’t be changed. The big reason I liked this one was because It takes standard AA batteries. If I want rechargeable batteries I can just charge them and in a charger and put them in this unit. I feel AA batteries are perfect for backup power. They are relatively cheap and plentiful now to stock up on and in a collapse scenario I feel they would still be able to be found. With that said lets get down to the review and see how this charger performs.
