Bonjour je n'ai pas compris comment fonctionne le rechargement de la KNOG PLUS arrière. Sur mon PC portable, j'ai bien reconnu et connecté la KNOG ; mais comment savoir si elle est en phase "recharge"?? Merci pour votre retour, bien cordialement, Arnaud HUMBRECHT


Bonjour, lorsque la lampe est branchée en USB celle-ci s'allume de manière fixe. Lorsqu'elle est entièrement chargée, la lumière s'éteint. Bonne journée :)
