Depending on how you connect it, these chargers are draining my phone's battery. I overslept at work because I plugged my phone in before bed thinking it was charging and woke up the next morning to a dead phone. I used a different charger to charge and then used this charger again to see what was wrong. Then it started draining the battery. If you detach it from the charging cube and turn it upside down, it will charge. I've never heard of it, but I won't buy it again.
