Will this fast-recharge device work with hearphones?

We noticed that the Bose Hearphones is low-current-draw item. And our portable charger requires a minimum 50mAh current draw to charge the device, otherwise, the powerbank will turn off automatically. This design protects your device from getting too much current which may overcharge/hurt it.  So we recommend this battery:https://www.amazon.com/gp/product/B07S829LBX  .It has a trickle charging mode to charge small current devices such as Bluetooth earphones.

Hi bhaugen,

 

Thanks for this interesting question.

The input level for Bose Hearphones is

This appears on page 8 of the Bose Hearphones Owner's Guide.

 

I have a similar power bank from the same manufacturer. It shows the same warning on the web page for the product I have.  The unit I have charges my Bose Hearphones without issues. However, it does not appear to charge my Hearphones faster than other lower-rated power banks. 

 

Does that help?

Re: Will this fast-recharge device work with hearphones?

Thanks a lot, ST. I don't know how to evaluate the input levels.

 

But since you tried one of their power banks with the same warning, I assume it's at least safe.

 

I'm looking for something I can carry along with me to charge either my phone or my hearphones, both of which tend to die in the evening if I am out and about.
