Good morning. Do the BV 6000 supporto wireless charge? In this case, what wireless charger could I use?
Thank you very much?

No.

though, It has a connection port on the mainboard which means that they planned adding wireless charging, but in the end, didn't do so

Interesting. Maybe one just need to insert an antenna and connect it?
I wouldn't expect quick charging though. Would one night be enough to fully reload BV's battery? Maybe field strong enough to charge it would burn the NFC module?

You can buy in Poland model Rugged Phones A20 Qi, similar to BV600, but with wireless charging:

Much more expensive than BV6000, but I suppose it can be upgraded version of BV6000 made for a seller in Poland. This could explain the additional connection port on the mainboard.

It is possible to buy a Qi-receiver and insert it in the phone case. it must be connected to the usb port bacause the two solder joints on the mainboard don't work. NFC antenna must be replaced to have enough place for both antennas. It needs 6-7 hours for full charging. Some users at 4pda rissia tried it. I have the parts here and wanted to try it when my spare-backpart for loudspeaker arrive. Bit it never arrived until half a year.
