Today, I received the PowerReserve battery backup device and was flabbergasted to find that it doesn't automatically switch over to backup; you have to manually turn it on. Also, due to this incredibly idiotic design, it is also incapable of charging its own batteries; in fact, the instructions explicitly say that you can't use rechargable batteries! Did Verizon job this design out to the Three Stooges? Absolutely useless! I am hoping that I can somehow get one of the older backup devices that will automatically switch over, but does anyone know if these older backup devices charge their batteries?
