ChargerLeash showed its smart charging cables at CES that sound off when you unplug your phone or tablet to remind you not to forget your charging device. They support a wide range of phones and tablets by measuring the specific high and low current states and alarm when they see the power use cease. Equipped with a sleep button for times that you want to leave the cable attached, it is easily possible to turn off the alarm with a simple touch. The company was promoting its Gen 2 Pro Series line.

While more expensive than a standard cable by a factor of two (priced at less than $40 for most devices), it might be just the thing to carry on trips when the trouble of finding a replacement cable would be worth more than the difference. And by minimizing the number cables adrift in the world, ChargerLeash is promoting its line as eco-friendly.

The New Jersey-based company unveiled its latest addition to the Gen 2 Pro Series line— a $35 2-in-1 Micro USB and Apple Lightning charging cable, which according to the company, “fits Android, Apple, Blackberry, and Windows-based smartphones and is compatible with most mobile devices including tablets, MP3 players, digital cameras and camcorders.”
