      Thanks Mr10Percent for your comment. I have experienced the problem you mention, yet in the case of laptops, they are smarter and simply don’t charge, or let you know that the charger is not strong enough or both. In the case of simpler devices, they don’t, as it seems ot be the case for BS-A1. You are however right and the weird light signal (while charging) is almost certainly dependent on a non-compliant charging device.It is however curious as BS-A1 doesn’t come with a model specific charger but only a cable and should therefore be compatible with any USB-charger.

      My charger devices (both the transmitter and receiver) should at least theoretically be compatible with any USB-charging device.

      I’m using a wireless charging receiver (https://www.amazon.co.uk/UniQi-Wireless-Charging-Receiver-OnePlus-transparent/dp/B01J437ZXI) and a Xiaomi Mi 20W Wireless Chargingpad.

      I will try to charge my BP-H9i, as well as BS-Emerge and BS-level (they are all equiped with a USB-C adaptor) and will add the information on this post later tonight.

        Update,

        BP-H9i charge just fine wirelessly. I haven’t  checked the Emerge or Level yet but I’m sure now that the 1300-mili Ampere Qi receiver is too weak for BS-A1 and most likely same goes for Emerge ang Level. I will order 2000-ma version and will update this post

          My Gen3 H9’s charge via a standard Apple white plug with a USB-A to USB-C cable without issue (UGreen).

          What you may also have to check is that a) not all USB-C cables are equal and have same charge carrying capacity and from that b) not all USB-C cables are the same USB standard. In fact, it is a huge mess of non-standards.

          Im not sure what you are having a problem with Qi-chargers, cables or the power supply to these??

            As I wrote in the original post, I want to see of I can use a wireless charger instead of charging the BS-A1 using USB-C cable. I could then just place the BS on a wireless charger not needing to connect and disconnect cables. The charging transmitter is not a problem while it seems like the wireless receiver I have does not allow enough electricity through.

            Being able to connect the device to a wireless power source could simply allow for more clean, cable-less, and convenient placement of the more recent, small size Beosounds that use USB as power source

              thank you. I understand now.

                I got tired of connecting and reconnecting the charging cables to my BS-A1s so I decided to try to charge them wirelessly by adding a charging pad, like the ones you can add to mobile phones and a wireless charging dock.

                The good news is that it works and it looks like the device is charging and I can use the BS. However I’ve noticed that when I charge the BS wirelessly, the normal periodic yellow pulse that indicates that the BS is charging when I use a cable (ca 2 seconds per stroke) ) is now accompanied with a short yellow flash directly after each normal light pulse. So, something is different and I’ve checked the users manual and couldn’t find any information so I wonder if anyone else has tried this solution?

                More importantly, I wonder if I’m doing something that could potentially be dangerous in terms of risk for fire or damage to the batteries.

                  I did not know the BS-A1 could be wirelessly charged?

                  That aside, I think the devil may be in the detail: I notice that some of my USB-C power distributors cannot perfectly charge my laptop like say the Levono OEM charger. Even if it is rated at 65 or 100W output. It can charge – but the Laptop Bios recognises it as non-OEM. Also, lesser non-OEM USB-C chargers can burn themselves out quickly compared to the OEM spec.

                  So yes, it can work and I’d be tempted to try it but the longevity may be shorter than expected. This

                  looks very similar to the B&O charger (fit and finish on the outside is obviously different) but would I try and charge say a Halo with the Amazon or with the B&O version. I’d go for 7 Amazon ones every time.

                    Actually BS-Emerge seem to be very specific to its power source. I’ve tried to connect it to three different USB-C chargers with capacities from 10 to 30 watts and it doesn’t react to any of them (the lamps on toop doesn’t turn on at all), which is strange.

                    That’s because your (older) power supplies are not USB-PD compliant. See a previous thread and scroll down to the end:

                      Update:

                      Got the 2000-mA QI charging receeiver today and the BS-A1 is now charging as it should so the earlier problem dependen on the low capacity of the first QI charging receiver (1000-mA).

                      I’ve also tried it on a BS-Emerge, which doesn’t start at all. Actually BS-Emerge seem to be very specific to its power source. I’ve tried to connect it to three different USB-C chargers with capacities from 10 to 30 watts and it doesn’t react to any of them (the lamps on toop doesn’t turn on at all), which is strange. On the B&O charger it states different outputs (dependent to the voltage out) but neither of mine with similar outputs seem to work. So, it doesn’t seem like I can power BS-Emerge wirelessly, which will probabaly be the case for BS-Level as it requires eve more watts than BS-Emerge.

                      The good thing is that at least I can now charge my BS-A1s wirelessly.

                      I wish B&O could come up with new over-ear headphones that could charge wirelessly too.
