Do you mean you didn't measure output voltage of any kind from either charger, or they both output the same measured voltage?
I ask because some supplies may not engage their output until they've been connected to a device, through the use of a sense pin that identifies the device and charger to each other. This is the reason some laptops cannot (easily) use off the shelf third party chargers. Could you elaborate on what brand of chargers they are?
Also, I am not what your friend's budget (if any) is, but perhaps I could recommend something like this?
