Actually, there is a much lower tech that I’ve pointed out before, at least for ReSound, maybe not for Phonak? Just buy a 2nd charger case. If you leave both charger cases plugged in all the time, you have TWO WEEKS of HA power stored in those two case when the lights go out.
I think the basic problem is sweet, innocent disposable users never seem to want a miss an opportunity to diss rechargeable rather than peacefully co-exist (my preference). No one has yet answered my question as to with disposables whether you get a good read out on your HA SOC and avoid the forgetful problem that the batteries start to crap out on you right when you most need them and it’s inconvenient to change them out .
Actually, the bigger problem in the U.S. is that it only prepares for the 50-year disaster, never the 500-year one. How many people were killed in Japan in the magnitude 9 Fukishima earthquake? - 152 unfortunates. I wouldn’t want to bet the same will be true in LA and SF when a similar big one strikes and that’s something that’s a bigger worry than whether one has chosen disposables or rechargeables - what is it, the Whittier Dam above LA - fills with a big rain storm before the Big One, the dam breaks in the shakes, and there go a whole lot of people.
So if you’re interested in rechargeables, just buy ReSound and get an extra charger or two and you’ll be able to go weeks without electricity. Since I can hear pretty well without my HA’s, buying a spare charger is an option for me.
Correction:: I’m way off on the # of people who died in Japan as a result of the magnitude 9.0 earthquake off the coast of Japan. The total is 15,800, estimated (or more). I misheard the number while listening to a recent Science Friday radio program segment on the dangers of the Whittier Narrows dam above L.A. It’s a good idea to think about the potential for disaster in your area of the country, how critical your HA’s are to surviving and communicating in a disaster, and make plans to preserve your HA’s and their power supplies, maybe keep spare power supplies both at home and work, etc., especially if you hear very poorly without your HA’s. cnicklo made a good point in asking folks to consider what happens to their hearing in a big disaster.
