iPhone Pebble Portable Charger Review

Tech Blog - Most people nowadays carry phones with them - to school, to work, to anywhere. And 'anywhere' doesn't guarantee you of having a full battery all the time, neither does it have sockets to cater to the needs of your phone whenever it runs out of juice. We depend on these gadgets in order to be able to communicate with the world. If they run out of batteries, they would become no more than useless. Thus, keeping a portable charger in hand is a necessity.

The Pebble Portable Charger would be the most likely to meet the needs of having a fully charged battery while you're on the go. Measuring only 9.8cm x 7.2cm x 1.8cm, the Pebble Portable Charger can hold upto a whopping 500 mA (milliAmperes) worth of battery.It would take someone around five hours to fully charge the Pebble. Nevertheless, it would be worth the time since this portable charger can fill up an iPhone upto four times its capacity in just over an hour for each time you recharge. Aside from iPhones, the Pebble Portable Charger is compatible with other Apple devices, Nokia, Sony Ericsson, and any other devices that can be recharged using a mini USB. Its rubbery finish will assure you that it would be slip-proof from your hands.

Having the Pebble Portable Charger handy all the time eradicates all excuses of having run out of juice along the way. At around $80.00, this portable charger would be very essential to every traveler, and eventually, to everyone.
