Bests & Worsts Reviews from Amazon

I have had these 34 months now and they still work just as well as when I bought them. I use each one every week, sometimes more, since I work in the field doing home visits. I even ordered more when I started doing longer camping trips. Why I love them: - I have the iPhone XS Max and I can get 1.5 charges from each battery. Surprisingly fast. - With an adapter cord I charge my ipad pro 11, and get a full charge (but it completely drains the battery). - Fully charge in less than 5 hours. - And you get two for the price of other batteries! I was told many years ago (don't know if it's still true) that all rechargeable batteries need to be used and recharged regularly. I had a rechargeable radio die because I left it sitting in a closet for eight months without use. So if you’re buying these just in case of an emergency, I would recommend you use them on a regular basis. But I am definitely not an expert.
