2. ZAGGsparq: How are you going to stay in contact with your fellow fans if your cellphone is dead? ZAGGsparq ($62) is a portable charging device with enough power to charge up to four USB devices. It’s lightweight, small and will be handy when your cellphone is about to go dead. Even better, you can make sure that your phone is fully charged so that your iGrill is able to send you messages to let you know the burgers are ready.
