My mobile blogging today did a number on my iPhone battery and AA backups. Didn’t think it would make it through the day, but it did. Still, I set up my system so I wouldn’t have to worry about that. Thus, I was glad to meet up with folks at PowerGenix and their nickel-zinc batteries offering 1.6V, higher than the 1.2V of NiMh rechargeables and even the 1.5V of alkalines.
By the time I met them, my AAs were already tapped below the point of being able to recharge my iPhone. I told them my story, showed them my setup, and they were happy to help me out. The mAh rating on these look low at ~1500 mAh, but that’s because the output voltage is so high. Measure it in watt-hours, voltage x amperes, and it’s very competitive. Will give them a whirl around the floor and report the results.
