I have been keeping my eye on the prices of the awesome BlackBerry Extra Battery Charger Bundles for both the BlackBerry Z10 and Q10. The prices started at around $50 but now they are closer to $30. These bundles include both an extra battery for your device along with a charging pod that also doubles as a backup battery. In short its a pretty slick deal.
Amazon now has the BlackBerry Q10 extra battery charger bundle for $36.18 with free shipping. They also have the BlackBerry Z10 extra battery charger bundle for $30 with free shipping.
