Hmm.. I've never timed it, but it's the same as the original battery. I usually carry 5 batteries but never need to use 5, I only use 2 for all day shooting, which is literally a full day (8-10 hours). Hope this helps.

Simply connect any 5V 2.1A Max output power source via the Micro-USB cable to safely charge the battery in the included charger. The connected power source can be a mobile phone adapter, a car charger, or a power bank, etc.But please do not directly connect the charger with power supply higher than 5V 2.5A.
