As many have discovered, many of the battery packs on the market will not charge such a low-current device as a hearing-aid charger, BUT I have just purchased an AUKEY Power Bank 15000mAh Portable Charger from NewEgg.com (I couldn’t find it at Amazon), and it works fine with my Phonak Charge and Care: it has a special setting for charging low-current devices.
It’s NewEgg item 9SIAWR7F3N3359 and is now listed at $49.99, which is a lot more than the “sale price” I paid earlier this week.
I’ve read good things about those too, but they’re more expensive than the sale price of the Aukey.
It’s back on sale today, Aug 17.
And for a little less than I paid.
I have a jumper pack for my car. It has a multi-USB cable and has been used to charge a phone. I haven’t tried with my aids but will give it a go.
Common problem seen with most bigger packs is they will assume that there is “no load” and shut off when the slight amount of power drawn to charge a set of HAs is all it sees. My HAs draw ~10ma max, and I see ~30ma when my charging case is charging both the aids and the battery. Many packs will shut off if they don’t see ~60ma.
