Power bank compatibility

Do you have the charger that needs to be plugged in or one which cahrges for multiple days?

How much amperage do your aids use in a day? How many days’ charge does your charger’s battery (if it contains one) hold? How many day’s will you be camping?

That computation should tell you how much amperage the power bank needs to deliver. Use that amperage to size the power bank, but note that power bank specs can’t deliver the promised current - there’s a formula for computing how much a power bank can actually deliver.

As for compatibility, what size cable does it need - USB-A male, USB-C, etc.? My obsolete bank needs male USB-A for output and mini-USB for input. My rechargeable aids, when I had them, needed mini-USB input. My power bank has a USB-A output cable and provides 2 inputs, 1 amp and 2 amp.

My guess - hope - is that newer chargers need USB-C drawing more power.

To follow up on this.

If I was in a similar situation looking for a Power Bank for my Jabra Enhance Pro 30, I would start with the charging case spec, which is:

Internal power source: Rechargeable lithium ion battery, 3.5 – 3.7 V, 2600 mAh
Power supply USB power supply, 5 V

Charger battery capacity (fully charged, not connected to mains power): Minimum 3 full charges of 2 hearing aids.

(So I would need 2600 mAh x 3.6V = 9.36 Wh for 3 days extra. Let’s approximate to 10Wh)

My understanding is a typical power bank internal battery is also 3.7V (TBC) so we can actually just look at mAh spec of the power bank (as both the charging case and power bank are 3.7V - presumably lithium batteries).

So If I get 10,000 mAh (actually a 10Ah getting rid of the milli and thousands!) power bank it will give me approx 4 full charges of the charging case, or a little under 12 days extra.

I would get a power bank double what you estimate you need, or maybe better 2 power banks.

Yes, all modern hearing aid charger cases and power banks should be USB Type-C in and out (but double check yours).

Now my new Garmin Watch does up to 24 days in Expedition Mode, so maybe I need need start thinking about some backpacking trips (and powerbanks for my hearing aids)!

There are other threads in this forum that have discussed the compatibility of the Lumitys with the Paradise Combi chargers. Apparently, ithey are compatible. They are cheap on eBay. For the price, it is worth trying them.

All in one. These units have been inspected, cleaned, sanitized and repaired to full working order and are in excellent condition.

Is it true that Phonak Audeo Lumity L90R’s do not work with any rechargeable charging case? - Hearing Aids - Hearing Aid Forum - Active Hearing Loss Community

This is also a situation where a secondary pair of well-programmed hearing aids in a disposable battery form would come in handy! Not as a substitution, per se, but as a backup option.
It would provide instant power replacement, no electricity required.

My power bank would not stay on when I tried to charge my Sennheiser Sonite Rs. But while doing some research one pak I read about said for “low current” charging tap the on button twice on the power pak. Well I decided to try that with my current power pack and low an behold it works. The power pack stays on until the aids are fully charged. Try it on your power pack, you might get lucky like I did..
