We-Vibe tango – discreet massager

We have the Salsa and the Touch. They both use the same charger. The Salsa and the Tango are identical products except the Tango has a lipstick type tip and the Salsa is smooth all around. The first time we charged one of them it took about 3-4 hours for the light to go off. Since then, we have used one or the other of them for up to two hours without noticing a drop in power. Hope that helps.
