I have rechargeable hearing aids (Unitron Moxie B9), which go into a charging case to charge. If in the case, they don’t automatically turn off (which is stupid, because if they’re in the case, they aren’t in your ears), so if the case isn’t plugged in, the hearing aids are on and active, using up the charge and sometimes auto-connecting with my phone, so I don’t know I’m getting a call. If I leave the case unplugged for a couple days with the hearing aids in there, the batteries will be dead when I go to use them.
I want a power bank that will keep the charge going so the hearing aids stayed fully charged in the case and they don’t auto-pair with my phone unless I’m wearing them. The case itself doesn’t have any sort of battery storage capacity (which I think is dumb). What search terms could I use to find a power bank that doesn’t shut off?
I have used a RAV Power powerbank for years now (just the one) and it has worked great. Still doing great to this day.
That said, maybe they have changed (I dunno) and I am sure there are plenty of manufacturers of these things that will get the job done just fine. Figure out the power needs and physical size you want and then do a Google search and you will likely find what you want.
I have a couple Anker power banks, but you have to turn them on, and if the hearing aids are fully charged, they turn off. They don’t turn back on by themselves, so then the hearing aids lose power. I need something that won’t turn all the way off, so as the charge runs down in the hearing aids, it’s automatically replenishing them.
A quick Google search says Voltaic battery packs are “always on.” Not sure if that is what you want or if that is a good idea (I do not know). Read that again…since so many do not do this there may be a good reason for not being always on.
I’m slightly not sure, having next to no knowledge about hearing aids, but if you require a power bank with a standard AC grounded receptacle, I’ve had very good luck with products by Jackery used at work. They have the usual USB connections as well, but they don’t turn off unless you turn them.
Otherwise, I have a power bank in the car that is capable of jump starting an engine as well as powering DC equipment using USB ports. I don’t recall the brand name, but it’s performed flawlessly for years, and is dead easy to use; I’d expect most of those to be about the same especially from a reputable brand, like Anker, or the Ravpower. Generally not too expensive compared to a full battery pack with AC power capability.
I have help on power banks, but I wanted to ask about this.
I have similar aids from Beltone. They absolutely positively turn themselves off when they go in the case. If yours are supposed to do that but aren’t doing it reliably, they or the case are broken and should be repaired rather than band-aiding this with some power bank that will also need to be kept charged while the aids run it down.
If the problem is that you have to remember to turn them off manually and sometimes don’t, well, I don’t have a great solution for that.
What you’re looking for is “trickle charging”, meaning that when the charger (power bank or plug-in) senses that the device is fully charged, it then continues to charge the device at the same rate as it’s self-discharge rate, thereby keeping it fully charged.
That said, I haven’t had problems with my Anker power banks not keeping things fully charged when plugged in. I don’t think it’s full trickle-charge, but rather whatever device is is self-discharges to some amount, then the power bank recharges it, and so on- more of a peak/valley graph of charging than a lower, smaller current if that makes sense.
