    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 Iโ€™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 Iโ€™ve checked the users manual and couldnโ€™t find any information so I wonder if anyone else has tried this solution?

    More importantly, I wonder if Iโ€™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 โ€“ 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 Iโ€™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. Iโ€™d go for 7 Amazon ones every time.

    Thanks Mr10Percent for your comment. I have experienced the problem you mention, yet in the case of laptops, they are smarter and simply donโ€™t charge, or let you know that the charger is not strong enough or both. In the case of simpler devices, they donโ€™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 doesnโ€™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.

    Iโ€™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 havenโ€™t  checked the Emerge or Level yet but Iโ€™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 H9โ€™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.

    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).

    Iโ€™ve also tried it on a BS-Emerge, which doesnโ€™t start at all. Actually BS-Emerge seem to be very specific to its power source. Iโ€™ve tried to connect it to three different USB-C chargers with capacities from 10 to 30 watts and it doesnโ€™t react to any of them (the lamps on toop doesnโ€™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 doesnโ€™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.

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