I am looking for a bluetooth speaker that can:
- charge through USB, so I don't have to worry about not losing a proprietary charger
- connect through a 3.5 mm line in (aux input) - so I can use it as a regular speaker with any device
The budget is 150 Euro maximum
Yet an important question is: if the speaker has the USB charging feature, then it can charge with any USB charger or maybe some of such speakers can only charge when using their own USB charger?
