As hard as it might be to admit, we are tethered to our smart phones. They have become appendages that are with us from the time we wake until we put them back into their chargers at night. The problem is that many phones don’t have the battery juice to last throughout the day. If you aren’t near a power source, at the beach or park, at a theme park, commuting on mass transit, hiking, (you get the idea), you might power down when you least expect it. Parents told us that when their phone battery indicator starts to flash red panic sets in. With the Magic Cube or Rose Stone it’s not a concern. Light and small, you simply plug it in, put it back in your purse and keep on with your day. After a while you will find your phone 100% charged. What parents really loved was that you could do this several times or with different phones without charging the charger. The variety of colors is a nice added plus to a truly invaluable accessory.
