I'm curious, next time I'm charging devices I'll check. Either way they're still not useful for anything beyond accessory charging, they're short and won't carry the power+signal necessary for my laptop (which, sigh, has two kinds of cables because the one Apple provided with their charger won't do Thunderbolt).
