MI Battery Experts CPB-iPhoneExtra4

iPhoneExtra battery is the thinnest and lightest external battery available for the iPhone 4 / iPhone 4S at the time of creating this page.

• Using a slimline lithium polymer battery built into a ultra thin casing that fits perfectly around the Apple iPhone 4 whilst barely increasing dimensions (adding a mere 12mm to the height, 4mm to the width including the protective bumper and only 6mm to the thickness).
• The weight added by the battery and bumper to the phone is only slightly more than a third of the phone's weight at a tiny 55 grams (less than 2 ounces).
• This battery rated at 1500mAh more than doubles the run time of the phone when used in conjunction with the phone's internal battery (1420mAh)
• The battery casing has a gloss black exterior and is supplied with a choice of two protective bumpers in gloss black & clear.
• The bumpers not only protect the phone but also alleviate the poor reception issue experienced with some iPhone 4's used without a protective cover.
• This external battery pack can be used instead of the internal battery to extend service life, in addition to the internal battery to extend the phone's run time by over double, or as a charger for the internal battery.
• Comes complete with micro USB to USB charge cable.
• Both the internal iPhone battery & the external battery are charged from the charge lead so the phone does not have to be removed from the external battery to charge the internal battery.
• World Voltage AC-USB charger and 12/24V DC car charger also available as optional extras for use with either the supplied Micro USB cable or the phone's original USB charging cable.
• Input 5V 500-1000mA, Output 5V 500mA
