It's always good to have a second battery for a camera, which can charge one while the other is used This is the advantage that Canon provides a small separate charger While often o must leave the battery in the device, which recharges the battery being connected by USB Result: you can not take pictures until charging is complete Problem solved with the Canon SX700HS And congratulations for the price of this material when compared to industry heavyweight, I mean the black and yellow sign that sells this battery nearly 60 euros!
